One of the approaches to prevent forests’ destruction is to improve the knowledge and participation of local people. In the present study, the role of indigenous knowledge of stakeholders and the participation of local people in the sustainable conservation of the west of Guilan forests were investigated using the theories of normative levels and planned behavior. The statistical population consisted of the residents and native forest dwellers of Sowme'eh Sara, Fuman, and Shaft cities, as well as the experts from General Department of Natural Resources and Watershed Management of Guilan. The sample amount was calculated using the unlimited Cochrane method, and 198 people responded to the questionnaire. The sampling method was simple random and for data analysis, structural equation modeling with SPSS 26 and Smart PLS 3 software were employed. The correlation test showed a significant positive relationship between participation and local knowledge variables with sustainable conservation and these two variables were able to predict sustainable conservation by 0.661 and 0.377, respectively. The structural equation modeling indicated that the experience of forest destruction through the weak participation of local people and indigenous knowledge has an indirect effect on adaptive behavior in sustainable forest conservation. According to the theory of normative levels, the focus of indigenous communities on the promotion of indigenous knowledge as an objective concept along with their focus on abstract concepts such as participation in the conservation of degraded forests can motivate protecting forests. This issue is accordance with the theory of planned behavior which creating a positive attitude among native people in the form of mental norms, lead to the control of behavior based on sustainable conservation. The results of the present research can be used to change the attitude of the general managers of the Natural Resources and Watershed Administration regarding the effectiveness of indigenous knowledge and cultural issues in the sustainable conservation of natural resources.

Introduction:             

AI refers to systems that exhibit intelligent behavior by analyzing their environment and taking actions, with some degree of autonomy, to achieve specific goals. In recent years, AI has also made its way into politics. In an increasingly interconnected world, the emergence and rapid development of AI has become a pressing issue in foreign policy decision-making. The exponential growth of data and the emergence of advanced AI technologies have opened new opportunities to enhance human decision-making capabilities. The integration of AI technologies into foreign policy decision-making processes has the potential to transform the way countries shape their strategies and navigate complex geopolitical challenges. The present study aimed to examine the role of AI in foreign policy decision-making, as well as the capacities and challenges lie therein.

Literature Review:

Several studies have dealt with to the use of AI in foreign policy decision-making. For instance, Berkoff (1997) explored the potential of AI to enhance individual and organizational decision-making capabilities, offering suggestions to the AI engineering community on what policymakers need to improve these processes. Putri et al. (2020) used AI to simulate ASEAN negotiations. They clarified how AI decision-making systems can help international relations experts and learners understand the decision-making process and government foreign policy strategies during diplomatic negotiations. Scott et al. (2018) tried to provide a basis for planning a foreign policy strategy that effectively responds to the emerging power of AI in international affairs. In the Iranian context, there is a notable lack of research regarding AI and its impact or application in foreign policy or international relations.

The study employed a mixed methods research design to analyze over 100 sources. Lawshe’s content validity ratio (CVR) method was used to validate the research hypothesis. Moreover, a panel of 12 experts, including academics and AI specialists, evaluated the hypothesis. With a CVR value exceeding 0.56, the hypothesis was confirmed, which showed the reliability of the research findings.

The applications of AI in foreign policy decision-making can be classified under two main types: 1) AI independent decision-making as in the virtual politician or AI politician and 2) AI as a support and supplement to decision-making in foreign policy. Currently, the concept of the AI politician is still at the theoretical level and has not been implemented in practice. Despite the efforts to promote the AI politician, these systems face many challenges and limitations. AI cannot understand complex foreign policy dynamics, cultural nuances, historical context, and diplomatic subtleties. Additionally, AI cannot evaluate and measure moral considerations or take responsibility for decisions. It is also unable to explain unexpected events, sudden policy changes, or emerging trends in world affairs. As a result, until these challenges are resolved, it is unlikely that humans will allow AI systems to make independent decisions.AI tools and methods (e.g., neural networks, expert systems, fuzzy logic, evolutionary computing, natural language processing algorithms, and computational argumentation technology) can be used to support and supplement decision-making in foreign policy. Artificial neural networks can be used to predict conflicts and armed confrontations. A concrete example can be found in Olaide and Ojo (2021) which developed a model to predict conflicts in Nigeria. Expert systems can aid in diplomatic negotiations by creating scenarios. An example is the simulation of foreign policy decision-making in ASEAN negotiations. Fuzzy logic can also be helpful as seen in Sanjian’s attempt to use the fuzzy set theory for modeling the decision-making process in the U.S. arms transfers (Sanjian, 1988). Genetic algorithms are the most widely used evolutionary computing methods in decision-making, which can shorten decision-making time and provide better decision-making plans for foreign policy decision-makers. In addition, natural language processing algorithms can reduce language barriers between countries, allowing diplomats and policymakers to communicate more easily with foreign governments and embassies. Moreover, special systems like the Project Debater can debate complex issues with humans, helping people make persuasive arguments and informed decisions.Using AI in foreign policy decision-making presents both capacities and challenges. AI offers several capacities to support decision-making in foreign policy. By helping decision-makers analyze abundant and diverse foreign policy data, AI enhances the ability to better assess decision risks and reduce errors in decision-making. This leads to more accurate predictions of international events and speeds up the decision-making process. Moreover, AI can reduce the influence of human biases, emotions, and interests, ultimately improving the quality of foreign policy decisions and enhancing the overall diplomacy process. Regarding the challenges, it is important to note that if the data inputted to AI is biased or incomplete, it can replicate and perpetuate human prejudices such as racism and sexism. The improper or unethical use of AI also poses a significant challenge. Additionally, AI systems lack the capacity for innovation and creativity and do not understand the value of human life or the consequences of military operations. Another challenge is verifying the performance of AI systems. The black box problem also presents a challenge, as the decisions made by AI cannot be easily explained by humans. Overall, considering both the capacities and challenges, researchers recommend that AI should support human strategic decision-making, with final decisions always being made by people in positions of authority.

The present study examined various applications of AI in foreign policy decision-making. The discussion concluded that the concept of the AI politician is not yet practical since AI lacks the capability to fully comprehend and navigate the complexities of foreign policy, thus making the emergence of such a phenomenon unlikely. In other words, AI cannot replace humans in making independent decisions within the realm of foreign policy. However, AI is effectively used today as a support and supplementary tool, serving roles in analysis and prediction to aid decision-making in foreign policy.

With the remarkable rise of China's economy in the 21st century and its unparalleled role in commercial and financial exchanges, the internationalization of the Chinese yuan has become one of the primary indicators of China's emergence as a significant political and economic power in the global order. As major challenges confront the dominance of the U.S. dollar on one hand and China’s ascending position in the global power hierarchy on the other, new debates have emerged regarding the potential of the Chinese currency—the yuan or renminbi—to become an international currency in academic and policy-making circles. Regardless of whether this internationalization is feasible, one thing seems certain: the consequences of such a development. The circulation of a currency such as yuan on the international stage, its status as a financial intermediary, and its transformation into a store of value are influenced by both political foundations and power dynamics. This article aims to explore the trends and consequences of the yuan's internationalization, taking into account the uncertainties within China’s political and economic system, and to answer the question of what consequences might arise from the yuan's internationalization in the context of political and economic uncertainty. This article adopts the uncertainty approach as a hypothesis and employs a descriptive-analytical and exploratory method. It posits that the internationalization of any emerging currency, including the yuan, requires a reduction of uncertainty in both political and economic domains. If these uncertainties are understood and managed, the internationalization of the yuan will be facilitated; otherwise, it will face significant challenges. The article assumes the yuan's internationalization as a given trajectory and does not aim at future forecasting. Instead, it focuses its analysis on the potential consequences by drawing on the historical experiences of more established and widely used currencies in the international monetary system, such as the U.S. dollar, within an analytical framework. The present article, assuming the future internationalization of the yuan within the international monetary system, identifies the consequences of political uncertainty in areas such as democratic reforms, China's role as a responsible power, its increasing influence in the Global South, and its portrayal as a major power. Economic uncertainty is discussed in terms of factors such as the adjustment and reform of China’s political-economic structure, changes in government-led price setting, challenges to the U.S. dollar sanctions regime, and the strengthening of Chinese economic institutions. The findings of this research show that the internationalization of a currency primarily depends on the economic capacities of the country that issues it and, secondarily, on the trust it commands from other countries. Despite the fact that, according to available statistics, the Chinese yuan ranks below traditional currencies such as the dollar, pound, euro, and Japanese yen in terms of international exchange, its rising trend indicates increasing internationalization. This process will undoubtedly be influenced by China's economic capacities. To reduce uncertainty and enhance predictability in the domestic environment, democratic reforms and greater economic and institutional transparency are necessary. Additionally, in the international arena, China must assume greater responsibility for global issues and work towards a positive portrayal of itself as a major power in the Global South, particularly in addressing global challenges.

Recently, social health has become significantly important as one of the dimensions of overall health. Additionally,the issue of students› social health is a crucial concern that poses numerous challenges. This study aimed to assess the socialhealth status of students enrolled at Bam University of Medical Sciences and identify the factors that influence it.

This descriptive-analytical study was conducted in 2017, involving 260 students from Bam University of MedicalSciences. The participants were selected using the quota sampling method. The data collection tool was the Social HealthStandard Questionnaire developed by Keyes. Data analysis was performed using descriptive statistics and chi-square test,performed using SPSS version 22.

Among the students studied, women accounted for 67.7% of the participants. In terms of age distribution, 53.6% fellinto the 20- to 24-year-old age group. Regarding social health, 78.4% of the students exhibited an average level. The dimensionwith the highest social health score was social participation (15.21 ± 4.30), while the lowest score was recorded for socialprosperity (11.18 ± 3.10). Female students had slightly higher social health scores (76.51 ± 14.33) compared to male students(76.21 ± 14.33). The research findings indicated that the relationship between social health and variables such as gender, age,marital status, and educational level was not significant. However, significant relationships were observed with interest in thefield of study (P = 0.002), field of study (P = 0.048), and academic year (P = 0.008).

The study results emphasize the significance of implementing educational and health promotion interventions aimedat enhancing social health among students. It is hoped that these interventions will provide a foundation for improving the variousdimensions of social health and fostering the overall well-being of students

Qasem Soleimani, one of the senior commanders of the Iranian Revolutionary Guard Corps, was killed on January 3, 2020, near Baghdad airport by an American drone authorized by the US president. US officials justified their actions on the basis of self-defense under Article 51 of the UN Charter and the anticipatory self-defense theory. This paper deconstructs the US legal arguments in accordance with international law, especially the rulings of the International Court of Justice (ICJ), and concludes that it is difficult to justify the US's actions based on the theory of self-defense, both in its restrictive and broad interpretations. Considering the fact that at the time, Iran and the United States were not in a state of armed conflict, resorting to the law of war to justify the United States' decision in assassinating General Soleimani would be baseless. Using deductive reasoning, this paper concludes that Soleimani's assassination was more a matter of revenge and deterrence rather than self-defense. The paper is organized into five sections, including an introduction, US domestic legal justification, self-defense under Article 51 of the UN Charter, anticipatory self-defense, and conclusion.

The current study has focused on the design and explanation of the Jihadi management model in the Islamic society based on the divine-political testament of Imam Khomeini. This research was carried out qualitatively. Data and components were obtained by the content analysis method, using MAXQDA software for drawing the network of topics. By deeply studying the divine-political testament of Imam Khomeini, the themes that were representative of Jihadi management in the Islamic society were collected in the form of open, central, and selective coding. Ultimately, the codes were classified by thematic analysis in the form of 81 open codes, 53 basic themes, 10 organizing themes, and 2 sub-themes. They include ethics, religion, selflessness, insight, God-centeredness, effective communication, and revolutionaryness, and the manager’s general characteristics, including manager and thoughtfulness, orderliness, lawfulness, and meritocracy, were identified.

Fear and hesitation of managers in their decision-making may sometimes cause devastating and irreparable consequences for themselves, employees and organizations. The purpose of this research was to discover and understand the phenomenon of decision-making phobia or decidophobia as well as its types among managers of government agencies.

This qualitative research was applied in terms of purpose and was descriptive-exploratory in terms of data gathering technique. Phenomenology method (study of the lived experience of people involved in this phobia) was employed to conduct the research. The data collection method was in-depth interviews with the participants. Therefore, based on the principle of theoretical adequacy and using purposeful sampling method, 20 public administrators and management professors were selected as the sample.

In addition to the recognition and understanding of decision-making phobia, the research findings contain the types of this phobia. There are seven main themes, including: situational decision-making phobia, headquarters-supervisory decision-making phobia, social decision-making phobia, legal decision-making phobia, individual-personality decision-making phobia, Job/organizational decision-making phobia and political decision-making phobia.

Shift handover is one of the critical tasks and major challenges among health care providers in hospitals. Most serious errors are caused by communication problems related to shift handover. Thus, it is essential to implement effective programs to overcome shift handover challenges in hospitals. This study aimed to evaluate the effects of the I-PASS (illness severity, patient summary, action list, situation awareness and contingency planning, and synthesis by receiver) program on nursing shift handover in hospital wards in southeastern Iran.

This study used a quasi-experimental design with a before-and-after method (without a control group) and was conducted in Pasteur Hospital in Bam City from January to March 2021. Sampling was performed using the census method. Participants included 47 nurses who work in critical care unit (CCU) and intensive care unit (ICU) wards. All nurses received shift-handover training based on the I-PASS program for 4 weeks (45-minute sessions weekly). The standardized I-PASS assessment tool was used in this study. Data were analyzed using SPSS version 25, along with the chi-square test, independent t test, and paired t test. P values less than 0.05 were considered statistically significant.

Among the participants, 89.4% were female, and 68.1% worked in the ICU ward. The mean age of the nurses was 33.25 ± 5.00 years old, and the mean year of their work experience was 8.08 ± 5.27 years. There was a significant difference in the mean scores of nursing shift handover before and after the intervention in the CCU ward from 1.88 ± 0.32 to 3.62 ± 0.98 (P = 0.018) and in the ICU ward from 2.37 ± 0.84 to 2.93 ± 0.35 (P = 0.013). Also, the mean scores of the CCU ward were higher than those of the ICU ward after the intervention (P = 0.01).

The I-PASS program can overcome many challenges in nursing shift handover and workflow. Therefore, this method can be a suitable alternative to the common methods of shift handover and patient delivery in hospital wards.

Creative deviance means defiance and disobedience to the orders of managers pursuing creative ideas which can bring positive results. The aim of the current research is to identify and prioritize the antecedents and consequences of creative deviation using the fuzzy Delphi method.

In terms of method, this research is a mixed research, and in terms of the type of use, it is an applied and exploratory research. The statistical population of the research included management professors and experts from Chaharmahal and Bakhtiari governorates, 16 of whom were selected based on the principle of adequacy and theoretical saturation and by snowball sampling. A semi-structured interview was used to collect data in the qualitative part, and a Delphi questionnaire was used to collect data in the quantitative part. The validity of the data collection tool was tested using theoretical validity and content validity and its reliability using intra-coder-inter-coder method. To measure the validity of the questionnaire, the content validity method was used, and the inconsistency rate method was used to measure the reliability.

Based on the data analysis, the most important factors among the antecedents of creative deviance include high IQ, risk-taking, creative thinking and vagueness of rules, motivational factors, employees' mastery of rules and management support, and among the consequences, creating creative performance and increasing the ability to innovate, increasing organizational efficiency, accelerating organizational goals and solving some organizational problems are among the most important factors.

Creative deviance has important practical implications for organizations. By giving employees some degree of individualism and psychological independence, managers can encourage creative deviation and creative efforts among employees.

Rare earth elements (REEs) play a crucial role in modern technology, making them essential components of various high-tech products, including electronics, electric vehicles, and military applications. While the quantity of REEs in each device might be small, their unique properties are irreplaceable, and they are vital for the proper functioning of these technologies. The growing use of REEs in advanced applications, combined with the establishment of international trade agreements in this sector, has led to increasing global competition in the rare earth elements market. China has emerged as a leader in the REE industry, a position it has held since the mid-1980s when it began to gradually dominate the world market. As demand for these elements continues to surge, the limited availability of extractable reserves has become a concern. Changes in consumer preferences worldwide, particularly the shift towards high-tech, environmentally-friendly products, have driven this growing demand. The increase in demand has had a profound impact on countries that control the production and market for rare earth elements, as they gain significant influence in the international political and economic arena.The central question explored in this research is the geopolitical consequences of China's near-monopoly in the international rare earth elements market. Given the indispensability of these elements in various industries, including electronics, medical technologies, telecommunications, and defense, their control has far-reaching implications. A country that manages to monopolize the rare earth elements market can wield substantial influence over global politics and the international political economy. This paper aims to investigate the geopolitical outcomes resulting from China's dominance in the international rare earth elements market.

THEORETICAL FRAMEWORK:

The concept of the geopolitics of natural resources is employed in this research to elucidate China's hegemony and its exclusive position in the international market for rare earth elements. Geopolitics involves examining how a country's unique geographical attributes impact its power dynamics and influence on the global stage. Among these geographical elements, natural and mineral resources are of paramount significance. Governments strive to manipulate and control the supply and demand chains within strategic markets to shape the structure of these markets, including those related to strategic resources, in alignment with their political and economic objectives.

The paper will utilize a descriptive-analytic methodology to address the research question and expound on the influence of rare earth elements on China's political, economic, and military power in global politics. This methodology involves the use of both current and historical data to discern patterns and relationships between the variables associated with the research question or hypotheses. It is a method employed to provide a comprehensive and analytical examination of the subject matter.

The research findings indicate that China's relative monopoly and comparative advantage in the production and supply of rare earth resources have evolved into a geopolitical asset, with implications for its economic, political, and military power in relation to major rivals like the United States. In essence, China's geopolitical control of rare earth elements has translated into advantages across economic, political, and military dimensions vis-a-vis its formidable competitors. Despite efforts by other governments to counter China's monopoly, these endeavors have not yielded substantial success thus far. Given China's long-term strategic plans, it is anticipated that Beijing will likely maintain its monopoly on these resources at least until the year 2050.

 CONCLUSIONS & SUGGESTIONS:

To summarize, the key findings of this research on the political and geopolitical consequences of China's relative monopoly on rare earth elements include:Price Determination: China's control over rare earth elements allows it to influence the prices of these elements, giving it a strategic advantage in the global market.Dependence and Vulnerability: Other countries, particularly the United States, become dependent on China for these critical resources, making them vulnerable to China's policies and potentially subject to supply disruptions.Bargaining Power of Chinese Companies: Chinese companies gain significant bargaining power in industries dependent on rare earth elements, enhancing China's economic influence.Impact on Employment: China's control affects employment rates in Western countries and elsewhere as industries relying on rare earth elements may face challenges due to supply issues.These developments collectively contribute to an increase in China's power position compared to competitors like the United States, Japan, and the European Union. Given Iran's substantial reserves of rare earth elements, there is potential for these resources to serve as a diplomatic tool in foreign policy, bolstering Tehran's bargaining power in the international economic arena and potentially influencing discussions related to U.S. sanctions against Iran.

Stock returns is one of the important factors in making decisions and investing in the stock market, which is of interest to investors and other capital market practitioners. Investors and other people involved in this market, considering the specialization of the subject, need tools that will help them in choosing the right investment option and choosing the right portfolio. In order to increase the efficiency and correct performance, the tools need to be tested in different times and markets. The main purpose of this research is to compare static and dynamic artificial neural network models in estimating stock returns in the Tehran Stock Exchange in the period 1391-1400. In order to obtain the required information, the sources and records available in the libraries as well as the information available in the stock exchange and kodal system have been used. Excel and MATLAB software have been used for storage, processing, variable measurement and statistical analysis. The results of the research showed that the dynamic artificial neural network model has better predictive power than the static artificial neural network model in estimating stock returns in Tehran Stock Exchange.

Nausea and vomiting are among the most common side effects of chemotherapy, and despite using pharmaceutical treatments, no desired outcome has yet been achieved in this regard. Therefore, using non-pharmacological techniques has been recommended.

The present study examined the effect of overshadowing on chemotherapy-induced nausea and vomiting in children with leukemia.

In this clinical trial study, participants were 70 children aged 3 - 18 years admitted to the Oncology Department of Mofid hospital in Tehran, Iran, and were randomly assigned to 2 intervention and control groups. A flavored candy was given to each child in the intervention group 10 minutes before the start of chemotherapy. This process was repeated during 3 rounds of chemotherapy. The severity of nausea was measured with the Baxter Animated Retching Faces Scale. The frequency of vomiting was measured using a checklist in both groups 10 minutes before and immediately after chemotherapy. The data were analyzed with SPSS software (version 25).

The data revealed no statistically significant difference in the severity of nausea in the first and second chemotherapy rounds between the intervention and control groups (P > 0.05). However, there was a significant difference in the third chemotherapy round between the 2 groups (P < 0.05). The severity of nausea and frequency of vomiting in 3 chemotherapy rounds was not significant (P > 0.05).

The results indicated that overshadowing was not effective in reducing the severity of nausea and frequency of vomiting. Further studies are needed to determine the potential effects of this technique on gastrointestinal symptoms, including nausea and vomiting.

There are always concerns about the environmental and human consequences of the widespread use of pesticides. This study aimed to determine the role of pesticides in the development of autism spectrum disorders in children through meta-analysis. All studies (11 articles) that had the potential to be used in our study were exported in EndNote X8 software and reviewed by authors. We extracted the required data, and we used Stata software (version 12) to analyze the pooled effect. Random and fixed-effect models were used to determine the combined estimation using the “metan” command.The results showed exposure to organochlorine pesticides could increase the risk of autism by 32% (OR=1.32; 95% CI: 1.14-1.53). The first trimester of pregnancy had the highest risk for autism (OR=1.23; 95% CI: 1.15-1.31). The cumulative meta-analysis showed a decreasing trend for crude and adjusted odds ratio over time.This study showed that exposure to pesticides can increase the risk of autism, and the time of exposure to pesticides is associated with the risk of autism. These results came as the cumulative meta-analysis results for crude and adjusted odds ratios showed a decreasing trend over time.

Recognizing and introducing common cultural elements significantly affects convergence and divergence among nations. Cultural commonalities, or awareness of them, facilitate international collaboration and communication. UNESCO's primary mission is to promote international cultural cooperation and mutual understanding across cultures by developing institutional mechanisms. As one of the significant universal cultural spheres, the cultural Iranian civilization sphere has always had an excellent capability for developing cooperation among political units linked to it. In this regard, the question arises as to how UNESCO uses its cultural policies to create political-identity ties among countries within the cultural Iranian civilization sphere. This study employs a descriptive-analytical method within the theoretical framework of cultural diplomacy, drawing on library and statistical sources. It aims to investigate the current state of UNESCO's diplomatic mechanisms and to provide alternatives to their efficiency. According to the findings, UNESCO has taken steps to disseminate cultural convergence in the aforementioned civilization sphere by implementing cultural projects such as World Heritage, Intangible Cultural Heritage, Memory of the World Programme, Unitwin/UNESCO Chairs Programme, and Creative Cities Network. Although this procedure establishes multifaceted cultural relations among nations in this sphere, it has been affected by some executive, political, and social challenges.

Although the conflict between Russia and Ukraine is mostly interpreted based on geopolitical propositions such as NATO’s expansion towards the Eastern Europe, the cultural identity and the inference of the political elites in both countries also play a significant role in escalating this battle. In some cases, the way of interpreting identities, which are defined on the basis of a sense of individual affection to the society or a specific group according to a set of cultural and social features such as religion and language, has been influential in creating friction in human societies. In addition to expansion of “self and the other” in the mental situation of the citizens, this interpretation has a great impact on the perception of politicians about their ego and its function in relation to other countries. Meanwhile, the conceptual dimensions of this research have been based on cultural revanchism and radicalism. In order to answer the main question of the research, a descriptive-analytical method has been used and the data has been gathered through library and statistical resources. The findings of the present research indicate that reactional policies of both parties regarding one another and in ties with past humiliations and present threats have roots in “contradictory and converging” Russian and Ukrainian cultural identities. These roots, within the framework of historical, ethnic, lingual and religious perceptions, pave the way for escalating the current conflict between the two countries.

Different factors in the workplace may create potential health risks for workers. Noise is one of these factors and it is considered as a concern through the world. The aim of this study is to provide information on the prevalence of noise-induced hearing loss (NIHL) among cement factory workers.

In this descriptive-analytical study, 283 workers were randomly selected from different production units in a cement factory. Equivalent Sound Level (Leq) was measured by using a Casella CEL-320 ‎ dosimeter and Sound Pressure Level (SPL) was measured by using a TES-1358 sound level meter (SLM) (sn: 090717269), with high accuracy. Audiometric tests were conducted by using an AVA C88 audiometer. Hearing Threshold Levels (HTLs) were calculated at different frequencies for both ears. Collected data were analyzed by using SPSS.16 software and statistical tests.

About 55 percent of the participants suffered from some levels of hearing-loss at the frequency range of 4- 8 KHZ. There was a significant difference between the mean HTLs ‎ of left and right ear at most frequencies. The highest mean of sound pressure level (SPL) was measured in crusher unit and the lowest mean occurred in bag-filling unit.

Occupational exposure to noise has the potential to cause hearing loss in cement factory workers. Therefore, it is necessary to perform effective measures to prevent the prevalence of hearing loss in units with high exposure risks.

The main purpose of the study: The present study has been designed to design a model of revolutionary management in an Islamic society based on the statements of the Supreme Leader from 2011 to 1400 AD.Research The method of this research was qualitative; Extraction of data and components by content analysis method is extraction of components, which has been done using MAXQDA software to draw the content network. By deeply studying the statements of the Supreme Leader Ayatollah Seyyed Ali Khamenei (as), the topics that were introduced by the revolutionary leaders in the Islamic society were collected in an open, pivotal and selective coding. Finally, the codes extracted by content analysis method were classified from a total of 50 lectures in the form of 66 open codes, 50 basic themes and 5 organizing themes. The work was presented as a model of revolutionary management in the management of the Islamic society. Which includes a comprehensive theme called revolutionary leader and 5 beliefs, political, professional, economic and personality indicators of a revolutionary leader were identified. It should be considered by all political advisors and managers of the country.

To understand climate change adaptation in forest management, it is necessary to be examined the general approach of perception and experience with daily behavior to adapt to climate change and the relationships between them. According to the National Center for Drought and Crisis Management, based on the SPEI index, 62.2 percent of the annual and 84.9 percent of decade of the total area of Guilan, respectively, is affected by drought. This study examines the relationship between people's perceptions and experiences of drought as a climate disaster and their daily behavior in terms of adaptation to climate change. Using the theories of world psychology, a questionnaire based on the Theory of Regular Levels (CLT) and Planned Behavior (TPB) was developed and distributed to the teenager generation at the school level in Rudbar city. Then, by using the structural equation model and path analysis, standard beta coefficients and factor loads were estimated using PLS software. For the research variables, convergent validity of AVE was greater than 0.5 and Cronbach's alpha for reliability was greater than 0.7, indicating the validity and reliability of the questionnaire. SEM results showed that drought experiences had an indirect relationship with adaptive behavior, but the two hidden variables of climate change and water saving perception had a direct relationship with adaptive and saving behavior. Significance of these relationships was confirmed by t-test with 95% confidence. The existence of a stronger relationship between the variable of climate change than the variable of perception of water saving implies that people focus less on abstract concepts (high level of CLT structure), while their focus is on objective concepts , like more daily behaviors. Therefore, considering the impact of climate change on climate disasters in Hyrcanian forests, it is necessary to plan climate change adaptive behavior to deal with climate disasters.

In this study, to determine Trump’s images of himself and Iran, the authors have focused on Trump's verbal behavior on Twitter. In this study, Maxqda 10 software was used. Through three-step coding, open coding, axial coding, and selective coding, the research seeks to answer these questions: what image does Trump represent of America and Iran on Twitter? And what are the reasons for this representation? The findings of the study are in the form of two concepts: the image of the self and the image of the other. In terms of self-image, authors have faced two sub-categories of Republican and Democratic achievements; Two category that Trump is trying to portray as a pro-American image of Republicans (with four categories) and the threatening image of US power by Democrats and Obama (with two categories) against Iran to achieve its intended goals of justifying anti-Iranian measures and extending his presidency. This, in turn, has polarized US foreign policy on Iran. Also in the terms of the image of the other, Iran is represented as the enemy of the United States that consists of three categories of the authoritarian regime, violating democracy and disturbing the international order. This type of Trump illustrations is influenced by anti-Iranian discourse in the US, The influence of Israeli loby and those around Trump, Trump's personality traits and his hate of Obama.

Professional ethics is a set of principles and standards of human behavior that affect individual behavior and leads to improve care that provided by medical staff. The present study examined the knowledge and attitude of medical and nursing students toward professional ethics in Iran.

This descriptive‑analytic study was carried out on 176 medical and nursing students in Bam University of Medical Science, Iran in 2019. In this study, students were selected by census sampling. Data collected using two researcher‑made questionnaires related to knowledge and attitude toward professional ethics. Data were analyzed in SPSS software.

The mean scores of knowledge among nursing and medical students were 86.56 (8.76) and 85.10 (12.19), respectively. The mean score of attitude among nursing and medical students was 127.06 (12.45) and 129.9 (11.88), respectively. Results of the Pearson correlation test showed a positive and significant associated between the score of knowledge and attitude nursing and medical students’ (P < 0.001), (r = 0.76) (r = 0.66). Among the demographics characteristics, student age was associated to their attitude and knowledge significantly (P = 0.03).

After the victory of communist revolution in China, Nationalism had been combined with communist teachings as result of cultural revolution at the Mao era. The outputs of mentioned process caused to formation of ideological and transnational principles in Chinese foreign policy. But after nearly three decades, People's Republic of China has not achieved its foreign goals and faced with turmoil in domestic economy. Therefore, at the late of 1970s Beijing endeavored to improving their relations with the outside world, especially with the United States. Over the 1980s-decade transnationalism ideas replaced with pragmatist nationalism. These developments paved the way for control the nationalism narrative by China development-oriented government. It is important to point out that one of the most important factors which influence states foreign policy is the kind of nationalism narrative. There are different kinds of nationalism in china's political temporary discourse, but only one of them has taken dominant position in China’s foreign policy. The aim of this article is to analyze the conceptual developments of Chinese nationalism and its impact on the development-oriented foreign policy. The research will examine main kinds of nationalistic attitudes in China and try to answer the following question: how do dominant narrative of nationalism contribute to construct the development-oriented foreign policy in china? Developmental outlook of China has directed it to interpret and promulgate nationalism in a pragmatist way as well as along its development-oriented foreign policy.

To analyze above mentioned issues the authors used a research desk method; we used various international publications, like monographs, scientific articles, and statistical data. This research has written by descriptive-analytic method and constructivism theory used as analytical framework.

Researchers owing to the goal of their research have classified Chinese nationalism from different perspectives. The authors of this article divided Chinese nationalism into three following categories: ethnical nationalism, liberal nationalism and pragmatism nationalism. The first one (ethnic nationalism) is usually defined as “to the process whereby a group or community that shares a common history, culture, language, and territory is persuaded to assert its identity in such a way that it acquires the authority to be in charge of its own affairs, usually through the creation of an independent state.” When ethnic nationalist interests are mobilized to achieve state interests, that is, state nationalism, a more assertive brand of nationalism tends to emerge. The second one (liberal nationalism) was introduced in the early twentieth century as a means to improve China through political and social reforms. It defines the nation as a group of citizens who have a duty to support and defend the rights of their state in the world of nation-states, but also to pursue individual freedoms. The third one (pragmatist nationalism) is a state-led and largely reactive, pragmatist nationalism does not have a fixed, objectified and eternally defined content, nor is it driven by any ideology, religious beliefs or other abstract ideas. This kind of nationalism is a form of nationalism that is more ready to compromise with the outside world for the sake of state interests. After Deng Xiaoping launched the reform pragmatist nationalism has taken significant foreign policy implications. China’s diplomacy began to serve economic development under the guidance of keeping a low profile and accumulating strength quietly. In addition, nationalism is becoming more influential within the government as it begins to overshadow communism and becomes the concept that draws the government and people closer to the economic objectives more effectively.

Facing chronic economic problems and acute political crisis at home and from a relatively weak geopolitical position abroad, the Chinese state took a pragmatic attitude toward nationalism and made sure that China’s foreign policy was not dictated by emotional rhetoric. The results of the article shows that China's development-oriented foreign policy has compelled Chinese ruling party to economic interpretation of nationalism which have led to impressive economic indexes so that will replace the US dominant economic status in third decade of new millennium.

The persistence or decline of US Dollar as a pervasive international currency has been one of the most important issues in the field of international political economy, since the beginning of the 21st century. While some scholars point to the continued dominance of US Dollar by citing the dominance of the United States in the world political and economic equations, others refer to the decline in the hegemony of this international currency due to the US economic weakness and its international alternatives. The present study aims to recognize the factors affecting the persistence or decline of US Dollar hegemony in the 21st century by using descriptive-analytical method based on considering available data and to examin the scenarios resulting from these situations. After raising this question that whether the hegemony of US Dollar as an international currency is still continuing or is facing a decline in the 21st century, this article is hypothesizing that despite the various factors affecting the continuation or decline of US Dollar hegemony, it seems that the continuity of US Dollar hegemony, as an international currency, will be strongly linked to the continuation of the existing international system and the US capability to keep it. The findings of this study in the framework of hegemonic stability theory show that the US Dollar hegemony will continue with some fluctuations depending on the willingness, volition and producing public goods by the United States in the short- and medium-term. However, in the long term, given the economic preponderance of China and other other emerging economies, a multi-currency monetary system may be formed in which the US Dollar would be a currency among other currencies.

The Arab Spring’s wave arrived in Syria on 26 January 2011 and the unrest flared up on 15 March 2011 in the city of Daraa, 58 kilometers south of Damascus. Since then, Syria has been immersed in a civil war. The Security Council adopted different measures to contain this crisis. The main objective of the present research is to analyze the performance of the United Nations Security Council in tackling the Syrian crisis. The findings of the present research imply that the Security Council, in its role as a conflict moderator, has shown a positive performance particularly in such areas as instituting ceasefire, deploying peacekeeping forces, promoting humanitarian activities, facilitating the political transition process, securing the territorial integrity of the country, assisting the refugees and controlling Syria’s chemical weapons arsenal. Even so, this body, due to the veto power of the permanent members, the complex nature of the crisis, and the conflictual interests of Russia and the United States and regional actors, has not been spectacularly successful in the termination of the armed conflict and enforcing peace. In order to explicate the matter, a descriptive-analytical method based on qualitative content analysis has been utilized and the library, internet-based resources, and United Nations documents have been used.

After the 1979Islamic revolution and the establishment of the Islamic Republic in Iran, hostility between Iran andthe Zionist Regime has been created and escalated. As the imperatives of Tehran's anti-Israeli orientation, the alliance with Syria plus non-state groups in Lebanon and Palestine and gradually the formation of the Resistance Axis have been established. This paper aims to address this question: What is the impact of the Resistance Axis on the strategic depth of the Islamic Republic of Iran?

The method of research is descriptive-analytical by using library and internet sources.

The findings of this paper indicate that the Resistance Axis influence on Iran's strategic depth through mechanisms such as making balance of power by establishment of resistance basesand creating loyal groups, a strategic alliance with Syria and other non-state allies, improving Iran's missile capabilities, increasing the military power of Hezbollah, Hamas and Islamic Jihad, and weakening the deterrent capabilities of the Zionist Regime.

The formation and development of the Resistance Axis has expanded the Islamic Republic of Iran’s strategic depth in the Fertile Crescent region.

The onset of the pandemic of coronavirus disease 2019 (COVID-19) has weakened traditional diplomacy in the field of international relations. As a result, interest in digital diplomacy and the activities in cyberspace have been growing by a multitude of administrative departments across government agencies in the world. The United States Department of State (U.S. DOS) has also become more prominent in digital diplomacy in the midst of the coronavirus pandemic by constructing strategic narratives against China. A key objective of this study is to explore the content and main reasons for narrative against China by using MAXQDA10 software package which is suitable for qualitative data analysis. A three-step coding is used to collect data in the content of Twitter, Instagram and YouTube accounts and channels of the U.S. Department of State to manipulate perceptions of the danger that China poses. The questions raised in this research are as follows: 1- With the advent of the Covid-19 pandemic, how does the U.S. State Department express its goals and aspirations in the international system related to attitude of the U.S. toward China by constructing strategic narratives? 2- Why is the United States promoting these narratives? After studying the three U.S. DOS accounts, it became clear that the main US foreign policy agency was attempting to highlight two strategic narratives: a) The right conduct of the United States in foreign and domestic policy and b) the wrong conduct of China in foreign and domestic policy. In the strategic narrative of the morally good or correct foreign and domestic policy behavior of the U.S., two genres were extracted (the savior of the world during the COVID-19 pandemic, the responsible state confronting China's misguided policies). In the strategic narrative of the China's wrong foreign and domestic policy behavior, two other genres were observed (China acting as a non-transparent and irresponsible government in this outbreak, an authoritarian state at home and an aggressive power abroad). Clearly, the U.S. government portrays China as a threat to its hegemony, and has taken advantage of the international community’s interest in the origins of the coronavirus pandemic to promote its anti-China agenda. In order to understand the importance of communication in international relations, the authors have used the theories of image and strategic narrative. Image theory show the perception of politicians and other actors of each other on any subject. Image theory is appropriate for the analysis of the nature of relationships in interactive contexts, because it enables an actor to define and understand one’s self-image and the image of others. Strategic narrative is also a means by which governments can express their interests, values and aspirations. Strategic narratives are a tool for political actors through which they can change the discourse space, manage expectations, and expand their influence. This is a qualitative study using content analysis method to show the hidden meaning of texts in the digital content of the U.S. State Department social media accounts. Accordingly, 247 tweets, 80 Instagram posts and 27 short videos from YouTube from the early days of the outbreak of COVID-19 in March to mid-August 2020 were selected. A total of 354 contents of the State Department’s digital activity related to COVID-19 and China's performance were systematically and randomly identified; then they were selected, translated into Persian, and analyzed. The analysis process consists of the three coding steps that are specified using the Maxqda10 software: 1- The first stage is the description stage, and is related to the formal features of the text, such as words and text structures. 2- The second stage deals with interpretation, and is a combination of the contents of the text and the mentality of the interpreter. Mentality here refers to the background knowledge that the interpreter uses in interpreting the text, which leads to the linguistic formation of genres. 3- The third stage is the explanation stage, and describes the relationship between social events (interactions) with social structures that affect or are affected by these events. At this stage, narratives are formed. By studying these three social media accounts, it can be seen that the U.S. State Department is trying to highlight two strategic narratives; the right behavior of the United States in foreign and domestic policy and the wrong behavior of China in foreign and domestic policy during the coronavirus pandemic. The U.S. State Department has highlighted four genres (four images). The self-image of Washington as the savior of the world in the pandemic era is highlighted, in contrast to China's misguided policies. In general, the use of social media platforms such as Twitter by the U.S. Department of State is expected to grow in order to reach foreign audiences with the aim of achieving U.S. foreign policy goals. In the case of China, the U.S. goal has been to justify itself and discredit China during the current outbreak of COVID-19. Thus, two images have been constructed: a non-transparent and irresponsible Chinese government, an authoritarian state at home and aggressive outside. The U.S. government sees China as a threat to its hegemony. For this reason, the United States has somewhat sought to tarnish China's image by narrating it negatively on social media.
