Abstract

As China's economic, technological and military power continues to rise, the US is increasingly concerned about Beijing's rising power. The United States views China's regional rise as a challenge to its hegemonic ambitions. China's increasing military power and political influence in East Asia has caused concern and suspicion among some of its neighbors and Washington. In the meantime, America for reasons such as; Countering the rise of China and supporting the freedom of navigation in this region has an active presence. Washington's effort to challenge China's maritime sovereignty reflects the United States' concern about China's rise and its determination to maintain its hegemony in the Asia-Pacific region. This causes the United States to try to create a ring of encirclement against China and contain it regionally and ultimately prevent the change of the balance of power to the detriment of Washington in East Asia. Thus, the research question is, what strategy does America follow to contain China's power in the South China Sea? The hypothesis that can be proposed is that considering that China's economic growth and the expansion of its maritime power are considered a strategic threat to the countries of the region and the United States; Therefore, Washington to prevent China from becoming a regional hegemon in East Asia; In an effort to prevent the rise and rise of China in the region, it has been found that this, while forming the balance of power in favor of Washington and its regional allies in East Asia, can help to secure the goals and interests of the United States in the region. Preventing China's rise to power and the containment and isolation of this country in the region, while shaping the balance of power in favor of Washington and its regional allies in East Asia, can greatly contribute to the development of influence and securing the goals and interests of the United States and its allies in the region.

Abstract

Introduction and Objectives: Unbalanced distribution facilities and services on Economic, Social and between regions, need to the planning and balanced spatial development the spatial structure of the country is inevitable This study aimed to determine the level development of the provinces of Iran and rank them based on the level of development and different levels of development of the country From 1345 to the present to help make the planning system and national policy has been done.

Methods: This study is based on cognitive research and in terms of the goal of the evaluation research method - comparative. The population according to the latest political divisions of 31 provinces and indexes evaluated 33 indicators in four dimensions (Economic, infrastructure-physical, socio-cultural and health), respectively. For data analysis, factor analysis and cluster analysis techniques were used.

Findings: The results show, between the provinces in terms of development, there are differences and inequalities. So that in Tehran alone during the decades the highest level of development and Sistan and Baluchestan province are the lowest and most disadvantaged. Comparison provinces during different periods of development of the center over the periphery of inequality.

Conclusion: According to the results of research to reduce disparities between provinces The placing of the country due to the talent and potential of each region and prioritizing disadvantage and less developed provinces in the planning of regional demands.

Abstract

Population growth and urbanization development are the main triggering factors of changes in urban land uses. These, in turn, result in changes in the components of radiation balance. The present study tries to analyze the role of urban land uses in radiation balance by calculating net radiation and its analysis. For this purpose, the Landsat 8 satellite image of 2016 was used. Characteristics of radiation flux including net radiation flux (RN), ground surface albedo (α), incoming longwave radiation (RL↓), incoming shortwave radiation (RS↓), outgoing longwave radiation (RL↑), and ground surface temperature were computed using Sebal algorithm.The values ​​of these components in different land uses (compressed residential, scattered residential, green area and wastelands) were analyzed using one-way analysis of variance (ANOVA) and Tukey’s test. The results of this study showed that the selected land uses have significant differences in the amount of radiation flux, therefore the wastelands are warmer than the residential areas by about 6 oC and the residential areas are warmer than the green areas by about 1.5 oC. The results also indicated that these differences are due to changes in output energy (α and RL↑), and any change in land use over time will ultimately lead to a change in the radiation balance and the temperature of those places, which this temperature increase, is different from the increase of the temperature due to global warming.

Abstract

Today, sustainable placement is one of the main approaches of urban planners and regional planners. The purpose of this study was to design and fit a consolidated model of localization of densely populated areas with emphasis on environmental balance. The purpose of this research is practical and it is a survey-analysis type. At first, according to the theoretical foundations, the research background and interviewing the experts designed the integrated model (basic conceptual model). Then the model was fitted by referring to experts (86 simple). The initial model of the research was investigated and tested using SEM using Smart PLS 2 software. The results showed that the factor loadings of all questionnaire questions were more than 0.4 and were therefore acceptable. The t-values ​​for all questions are greater than 1.96 and are therefore significant at 95% confidence level. On the other hand, environmental equilibrium in locating subtropical regions is affected by 7 criteria and 22 sub criteria, among which environmental quality had the highest impact (path coefficient= 0.5227) and semantic structure (path coefficient = 0.0353) the least. Also, the mean of the common index index was 1.147 and the coefficient of determination (R2) was 0.9184. The overall fit of the model (GOF) was calculated to be 0.55235. In the final study, it was found that all paths have significant coefficients and thus the conceptual model of research was confirmed.

Abstract

The concept of balance has been applied  into various areas such as  Davis's evolutionary perspective,  the field of systemic epistemology as well as  the concepts and interpretations of the Quranic verses about the phenomena of the earth's surface.  Davis's theory about the balance of forms and morphology states that the forms of the earth in longer periods of time are evolving or gradually decaying, in other words, they have progressive and irreversible change. This concept has strong entropy maximization and positive feedback, but without a doubt, what is meant by the concept of balance in Davis's point of view is comparable to what is meant by the systemic point of view and the concepts of verses from the Quran that show evolution, order, continuity and balance in phenomena. In this regard, there are three points of view that can be examined. They are similar considering two of the points of view, however, there are differences  regarding the time frame required for the destruction of the mountains.However, according to Gilbert's point of view, the appearance of the form and process can be associated to mechanisms of negative feedback. The results are subject to change and fluctuation with different intensities and cause the surface forms of the earth to change their shape according to the intensity of the fluctuation which does not contradict with the Quranic verses. Additionally,  Gaia's perspective, which examines life and its effects on the earth according to the positive and negative feedbacks in a system, is consistent with the concepts of the Quranic verses. This study is a fundamental research that aims to compare the three theories of Davis, Gilbert and Gaya with the verses of the Quran to discover their similarities and differences.

Abstract

The smallest change in energy exchange of Earth System Shifts the balance of life. In order to be aware of the solar radiation Balance, Recognition of the measure of Balance level of the input and output components of radiation of input Short wavelength to the surface of the earth and Long Output Wavelength, it is necessary from the earth. To study the energy balance of input and output in Iranian plateau, the input and output radiation data of NCEP / NCAR site was used With a resolution of 2.5 * 2.5 *, including 46 cells in Iran,. For each season, a representative month was considered And correlation, confidence level, coefficient of determination and amount of oscillation of input and output radiation were calculated in different regions of Iran. Finally, some calculations were presented spatially with the IDW method. The results showed that the maximum short-wave wavelength was 230 watts per square meter in August and the lowest was 52 watts per square meter in November. The highest long-wavelength output in August was 65 watts per square meter, and the lowest amount was January and November with 20 watts per square meter. The highest the amount of output increase has been occurred in August in the east of province South Khorasan with a correlation of 0.59 to 112 watts per square meter in 2001. In decreasing output changes, except for May, there was a decrease in the rest of the months. The highest long-wavelength output was in the northwest and in the provinces of Ardabil and Guilan.
