The prevalence of suicide attempts and suicidal ideation among university students is a global concern. Cultural values, social determinants, religion, and especially growing stress all play an important role in this. This systematic review aimed to identify potential protective and risk factors thought to be associated with suicidal ideation among students in the Eastern Mediterranean region and highlight the importance of developing an effective health care response. MEDLINE, CINAHL, Embase, PsycINFO, WHO Global Health Library, IMEMR, Web of Science Core Collections and Farsi and Arabic databases were searched for papers in English, Farsi, and Arabic. A combination of validated filters, free text keywords, and Mesh and Non-Mesh terms were used to retrieve relevant literature. A total of 2774 papers were found after the search, 257 selected for full-text review, and 72 papers included in the final review. Family and peer support play a potential protective role in the development of suicidal ideation among university students, while adverse life events, bullying, depression, anxiety, and other mental health conditions were identified as risk factors. Suicidality was likely under-reported due to stigma around social and cultural factors. Factors involving religion and culture may act as both protective and risk factors and require more in-depth investigation. The student population in the Eastern Mediterranean region face many challenges. The common theme of suicidality emerged as an indicator of an imbalance of resources and stress, which needs to be addressed proactively, given a most likely underreporting of suicidal ideation and attempts due to stigma., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Fadakar et al.

Green manure is used as an environmentally friendly technology to produce clean agricultural products. This technology not only helps reduce environmental and health concerns, but can also increase productivity. Green manure is especially needed in the production of paddy. Because rice as a strategic product is the main food of people in many countries of the world. Rice production using green manure can enable countries to develop and increase healthy production. However, the acceptance of this technology is low in many rice producing countries. In this regard, this study used an integrated and extended version of the theory of planned behavior to predict and encourage the adoption of green manure technology in Iran. To collect the required data, a cross-sectional survey was performed among Iranian rice growers and the results of hypothesis testing were analyzed using partial least squares-based structural equation modeling. The results revealed that moral norms of green manure, attitude towards green manure, perceived behavioral control on using green manure, and trialability of green manure have positive and significant effects on intention towards using green manure. In addition, bootstrap analysis showed that moral norms of green manure and trialability of green manure positively and significantly mediated the (indirect) effects of subjective norms towards application of green manure on intention towards using green manure. The results led to important practical and theoretical implications that could provide new insights for policy-makers, planners, and practitioners to develop and encourage the adoption of green manure technology to produce clean and healthy agricultural products., (© 2023.

Naturally abundant dyes are very attractive for the development of dye-sensitized solar cells (DSSCs). Hydroxycinnamic acid derivatives, such as caffeic acid (CA), ferulic acid (FA), and p-coumaric acid (PA), were considered for the selective harvesting of ultraviolet A (UVA) (315-400 nm) photons. Their spectroscopic and electrochemical properties were investigated both theoretically and experimentally. They were further successfully adopted as photosensitizers in UV-selective and visibly transparent DSSCs, which exhibited a power conversion efficiency of 0.22-0.38% under AM (air mass) 1.5G (global) illumination (100 mW/cm 2 ) and 3.40-3.62% under UVA irradiation (365 nm, 115.22 mW/cm 2 ), with a corresponding visible light transmittance (VLT) of 49.07-43.72% and a general color rendering index (R a ) of 93-90., (© 2023.

Conservation agriculture is an approach for managing agricultural ecosystems, improving productivity, increasing benefits and food security, and preserving resources and the environment. The core purpose of this study was to analyze the constructs affecting the intention to use conservation agriculture measures. For this purpose, protection motivation theory was applied as the theoretical framework. Validation of the model was done using a cross-sectional survey among Iranian farmers, and SMART PLS software was used to test the hypotheses. The results showed that the direct effects of the five constructs of perceived severity, perceived vulnerability, response cost, response efficacy, and self-efficacy were significant on the intention to use conservation agriculture measures. In addition, the variables of perceived severity, response cost, and perceived self-efficacy had significant effects on the fear of not using conservation agriculture measures. The results of the bootstrapping analysis indicated that the fear of not using conservation agriculture measures significantly mediated the effects of perceived severity, response cost, and self-efficacy on the intention to use conservation agriculture. The results of the present research help to develop protection motivation theory by defining new relationships between its variables and achieving a deeper understanding of these relationships. The results also can pave the way for social and psychological interventions in the field of adopting the principles of conservation agriculture in agricultural societies. Finally, the results of this research can be used as a decision-making tool and help for users and planners of behavioral changes to better identify the focus points and necessary strategies., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Bazrafkan, Valizadeh, Khannejad, Kianmehr, Bijani and Hayati.)

Aquifer storage and recovery (ASR) is considered as an innovative method and an alternative one for sustainable management of water resources that has, in recent years, attracted the attention of experts and thinkers. Implementation of this method would entail the participation and collective action of various stakeholders. In this process, farmers are considered as the most important stakeholders; and limited studies have been conducted on their intentions to participate in collective actions of ASR management. In this regard, the investigation of farmers' intention to participate in ASR and its determinants, using social identity models of collective action, was selected as the main purpose of the present study. For this purpose, using a cross-sectional survey, 330 Iranian farmers were interviewed. In this study, the ability of the dual-pathway model of collective action (DPMCA) and the encapsulation model of social identity in collective action (EMSICA) was evaluated and compared to explain farmers' intentions towards participation in ASR management. The results revealed that the both models had good predictive powers. However, DPMCA was a stronger framework than EMSICA for facilitating farmers' collective behaviors in the field of participation in ASR management. This is one of the most important results of the present research that might be used by various users including decision makers, managers, and practitioners of water resources management in Iran and generally the world. Finally, the creation of a " we thinking system " or social identity in the field of ASR management was highlighted as one of the most important take-home messages., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Valizadeh, Bagheri-Gavkosh, Bijani and Hayati.)

Conflicts over rangeland exploitation have been a serious challenge in Iran, rooted in human behavior. Accordingly, this study aimed to provide a comprehensive theoretical framework in the field of analyzing conflict behavior among rangeland exploiters. This research is a descriptive-correlational and causal-relational study conducted using a cross-sectional survey. The statistical population of the study was rangeland exploiters in one of the northwest provinces of Iran ( N = 66,867) of whom 384 people were selected as a sample and stratified random sampling method with proportional assignment. The research instrument was a questionnaire, the validity of which was confirmed by a panel of academic experts and the reliability of its items was verified using Cronbach's alpha coefficient. The results showed that the variables of personal norms (PN) and the perceived behavioral control were able to predict 25.9% of the variance in terms of the conflicting behavior of rangeland exploiters; besides, ascription of responsibility, PN, perceived behavioral control, and awareness of consequences, which have been proposed as activators of PN, were able to explain a significant percentage (63.5%) of the variance in terms of PN. Furthermore, analysis of the effects of environmental and cultural values showed that conflict behaviors of exploiters were mostly affected by their underlying values. Generally, the results of this study would help in the development of more integrated and comprehensive models in the field of exploiters' conflict behavior. Eventually, to change and improve the environmental behavior of exploiters to better management of conflict in rangelands, providing a list of considerations and competencies for agricultural extension and education, this article comes to the end., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Haji and Hayati.)

Environmental challenges to natural resources have been attributed to human behavior and traditional agricultural production techniques. Natural resource degradation in agriculture has always been a prime concern in agro ecological research and sustainability analysis. There are many techniques for assessing environmental performance; one of which, ecological footprint (EF), assesses human pressure on the environment and natural resources. The main purpose of this study was calculation of ecological indices including biocapacity (BC) and EF of rural areas of Fars province of Iran. The study was accomplished using survey and structured interviews consisting of three main questionnaires in two different steps. Different agricultural stakeholders, including farmers (for the first step) as well as the policymakers, extension managers and authorities (for the second step) were interviewed. Based on multi-stage stratified random sampling, 50 villages and 423 farmers were selected. Face validity and reliability of the questionnaires were assessed by a panel of specialists as well as conducting a pilot study, respectively. The paradigmatic perspectives of agricultural policy makers and managers (22 individuals) were also analyzed using another specific questionnaire by Analytical Hierarchy Process (AHP). Findings revealed that most of the studied villages faced a critical environmental condition due to the results of ecological indicator which was calculated in the study. According to the four main components of human ecology (POET model) including Population, Organization, Environment and Technology, village groups that differed in terms of sustainability level also showed significantly differences due to population, social participation, use of green technologies and attitude towards diverse environmental management paradigms. The causal model also revealed that population, green technology, social participation and attitude toward frontier economics, which were in accordance with the elements of human ecology model, were the main factors affecting the ecological index. Finally, AHP results determined the dominant economic perspectives of agricultural authorities. A paradigm shift toward the comprehensive paradigm of eco-development plus consideration of the results of the ecological indicator calculation as the base of agricultural planning at the local level were recommended., Competing Interests: The authors have declared that no competing interests exist.

Investment in the behavioral change projects would not be possible without knowing their prerequisites and determinants including intention, moral norms, identity, and place attachment. Therefore, this study aimed at the determination of the effects of place attachment (PAT) (place dependence (PDE), place identity (PID), and place affect (PAF)) and farmers' identity (conservationist identity (CONID) and productivist identity (PROID)) on the moral norms of water conservation (MNWC) as well as the intention of water conservation (IWC) of the Iranian farmers. This was a descriptive-correlational and causal-relational study. The instrument of the study was a questionnaire completed using a cross-sectional survey and face-to-face interviews. Hence, a stratified random sampling method along with a proportionate allocation was used to select 380 farmers. The research findings indicated that the PAT (PDE, PID, and PAF) and CONID had significant positive effects on the MNWC. In addition, MNWC and CONID had significant positive effects on the IWC. However, PROID had a significant negative effect on the MNWC and IWC. In general, it was found that independent variables (PDE, PID, PAF, PROID, and CONID) could predict 39% and 53% of the variance of the MNWC and IWC variables, respectively. Moreover, the social-psychological framework of the study provides practitioners, decision-makers, policymakers, researchers, and other stakeholders of the agricultural water management with useful practical and theoretical insights about the practices of behavior changes and social interventions. Finally, it is recommended that government decision-makers should further focus on the increased attractiveness of the rural and agricultural areas to increase PAT, MNWC, and IWC., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier Ltd.

Two donor-π-spacer-acceptor (D-π-A) organic dyes were designed as photochromic dyes with the same π-spacer and acceptor but different donors, based on their electron-donating strength. Various structural, electronic, and optical properties, chemical reactivity parameters, and certain crucial factors that affect short-circuit current density ( J sc ) and open circuit voltage ( V oc ) were investigated computationally using density functional theory and time-dependent density functional theory. The trans - cis isomerization of these azobenzene-based dyes and its effect on their properties was studied in detail. Furthermore, the dye-(TiO 2 ) 9 anatase nanoparticle system was simulated to understand the electronic structure of the interface. Based on the results, we justified how the trans - cis isomerization and different donor groups influence the physical properties as well as the photovoltaic performance of the resultant dye-sensitized solar cells (DSSCs). These theoretical calculations can be used for the rapid screening of promising dyes and their optimization for photochromic DSSCs.

A series of donor⁻π-conjugated spacer⁻acceptor (D⁻π⁻A) organic dyes featuring an azobenzene spacer were designed as chromic dyes and investigated computationally. The electron-donating strength was modified by introducing electron-donating units to the donor side. In particular, the trans ⁻ cis isomerization of the azobenzene-based dyes and its effect on the optical and electronic properties were further scrutinized. In both trans and cis conformers, a gradual increase in electron-donating strength promoted the natural charge separation between donor and acceptor moieties, thereby allowing the absorption of a longer wavelength of visible light. Importantly, the conformational change of the azobenzene bridge resulted in different absorption spectra and light-harvesting properties. The azobenzene-based dyes will open up a new research path for chromic dye-sensitized solar cells., Competing Interests: The authors declare no conflicts of interest.

There is a high risk of serious water shortages in Middle-East and North African countries. To decrease this threat water conservation strategies are gaining overall importance and one main focus is now on farmer's behavior. Among other dimensions it is assumed that normative issues play an important role in predicting environmental oriented intentions and actual actions. To empirically test the possible interactions the Theory of Planned Behavior was used, revised and expanded for the specific case on water management issues and applied to Iranian farmers. The results could not validate the TPB framework which emphasizes the importance of perceived behavioral control for intention and actual behavior and findings are much more in line with the Theory of Reasoned Action. Normative inclinations as well as perception of risk are found to be important for intention as well as actual water conservation behavior. Additionally, the importance and linkages of the dimensions are found to be different between sub-groups of farmers, especially between traditional water management farmers and those who already using advanced water management strategies. This raises the question if one-fits-all behavioral models are adequate for practical studies where sub-groups may very much differ in their actions. Still, our study suggests that in the context of water conservation, normative inclination is a key dimension and it may be useful to consider the role of positive, self-rewarding feelings for farmers when setting up policy measures in the region., (Copyright © 2014 Elsevier Ltd.

The aim of this study was to determine the effects of transformational leadership and its components on work engagement among hospital nurses. There are a few set of researches that have focused on the effects of transformational leadership on work engagement in nurses. A descriptive, correlational, cross-sectional design was used. In this study, 240 nurses have been chosen by stratified random sampling method which filled related self-reported scales include multifactor leadership questionnaire (MLQ) and work engagement scale. Data analysis has been exerted according to the statistical method of simple and multiple correlation coefficients. Findings indicated that the effect of this type of leadership on work engagement and its facets is positive and significant. In addition, the research illustrates that transformational leaders transfer their enthusiasm and high power to their subordinates by the way of modeling. This manner can increase the power as a component of work engagement in workers. Idealized influence among these leaders can result in forming a specific belief among employees toward those leaders and leaders can easily transmit their inspirational motivation to them. Consequently, it leads to make a positive vision by which, and by setting high standards, challenges the employees and establishes zeal along with optimism for attaining success in works. regarding to the results we will expand leadership and work engagement literature in hospital nurses. Also, we conclude with theoretical and practical implications and propose a clear horizon for future researches.

The present study examines the relationship between academic burnout and quality of learning experience and self-efficacy among undergraduate students. The sample consisted of 233 undergraduate students (106 men and 127 women) who were selected by stratified random sampling method. The participants completed the Quality of Learning Experience Scale, Academic Burnout scale, and General Self-Efficacy scale. This study is particularly interesting in the context of Iran, known for its equality-striving and high-quality educational system. Iranian youth, compared with youth in many other countries, have a lower level of well-being. The antecedents of academic burnout are divided into two categories: internal and external variables. In most studies regarding to the issue, one category is used to predict the dependent variable. However, in this study we utilized both ones; self-efficacy was considered as internal and quality of learning experience was used as an external predictor. Correlation coefficients indicated that all relationships between academic burnout and its components with self-efficacy were statistically significant. Furthermore, academic burnout and all of its components had significant correlations with quality of learning experience. Also, the relationship between resources with emotional exhaustion and professor-student relationship with academic inefficacy were not significant. On the basis of the results, through our research, we will expand academic burnout literature by focusing on its external and internal antecedents. In addition, we conclude with theoretical and practical implications and propose a clear horizon for future researches.
