A B S T R A C T Temperature is one of the climate elements that has fluctuated a lot over time. When these fluctuations increase and decrease more than normal and are placed in the upper and lower regions of the statistical distribution, if continued, it can lead to the creation of heating and cooling waves. The purpose of this study is to analyze the temporal and spatial changes in heating and cooling waves in Iran during a period of 50 years. For this purpose, the temperature of 663 synoptic stations from 1962 to 2004 was obtained from the Esfazari database. Then, in order to complete this database, the daily temperature from 2004 to 2011 was obtained from the Meteorological Organization of the country and added to the aforementioned database. In order to perform calculations and draw maps, Matlab, grads and Surfer software have been used. The results of this study showed that the index of cooling waves and heating waves, while having a direct effect on each other, had an increasing TREND in most of the area of Iran. The statistical distribution of the index of cooling waves is more heterogeneous than that of the index of heating waves. So that the spatial variation coefficient for cold waves is 84.22%. Also, the index of cooling waves has more spatial variability. The highest common diffraction of the index of heating and cooling waves has been seen in the northwest, east and along the Zagros mountains. Analysis of the indexes TRENDs show that heat waves have intensified in 65.8% of Iran and the intensity of cold waves has decreased in 48.5% of Iran Extended Abstract Introduction Temperature is one of the major climatic variables, which it has a direct impact on different aspects of human life. It plays an essential role in the growth of crops and is considered a key driver of the biological system(Reicosky et al, 1988). It is associated with several types of extremes, for example, heat and cold waves which caused human societies maximum damage. Past occurrences of heat waves hitherto had significant impacts on several aspects of society. Have increased Mortality and morbidity. Ecosystems can be affected, as well as increased pressure on infrastructures that support society, such as water, transportation, and energy(Dewce, 2016). The long-term change of extreme temperatures has a key role in climatic change. The form of statistical distribution and the variability of mean values and also extreme event indicate a change in the region. It can be a small relative change in the mean as a result of a large change in the probability of extreme occurrence. Also, the variation in temperature data variance is significantly more important than the mean, for assessing the extreme occurrence of climate(Toreti and Desiato, 2008). The average surface temperature has increased the world between 0.56 and 0.92 ° C over the past 100 years(IPCC, 2007). Meanwhile, it was in the Middle East, the average daily temperature increased by 0.4-0.5 ° C in decades(Kostopoulou et al, 2014; Tanarhte et al, 2012). Considering that not many studies have been done in the field of spatio-temporal Variations of the heating and cooling waves thresholds in Iran, in this study, the spatio-temporal Variations of the heating and cooling waves thresholds in Iran during 50 years were examined and analyzed.   Methodology The daily temperature from the beginning of the year 21/03/1967 to 19/05/2005 was obtained from the Esfazari database prepared by Dr. Masoudian at the University of Isfahan. In order to increase the time resolution of the mentioned database, the daily temperature of observations from 05/21/2005 to 05/12/2012 has been added to the mentioned database using the same method, and the exact spatial resolution (15 x 15 km) is used as a database. Threshold indices of heating waves are the average numbers between the 95th and 99th percentiles, that is, the extreme hot threshold to the limit of excessively extreme hot. For extreme cool, from the 5th percentile down to zero is used. Of course, a condition was added to these thresholds, which is that these thresholds must be repeated two days in a row. These thresholds were extracted for each day in the 50 years of the study period and used as the original database. In order to analyze the relationship between cooling and heating waves, Pearson's correlation coefficient was used and regression was used to analyze the TREND.   Results and discussion The average of cold waves was 5.26 ° C and for the heat waves is 30.20° C. Generally, if the temperature is upper or lower than this threshold, it is considered as hot or cold temperatures. A comparison of the median, mode, and average of cold waves with heat waves shows that the distribution is more heterogeneous for cold waves and its CV is 84.22%. In southern Iran, the average threshold heat waves are higher. This situation can be caused by the effects of subtropical high-pressure radiation, low latitude, and proximity to the sea. Though the threshold is higher in these areas, fewer fluctuations and changes are seen in the area. Heights moderate the temperature so they pose a minimum threshold for heat waves i.e. an iso-threshold of 25 ° C is consistent along the Zagros mountain chains, but in the west and east of Zagros Mountains, the threshold of heat waves is increased. Heat waves have increased in most areas of the country. So nearly 85 percent of the Iran has been an increasing TREND, of which 65.8 percent is statistically significant at the 95% confidence level. Still, more areas of the country (60 percent) have a TREND between 0.00828 and 0.00161. As can be seen, only 15% of the land area (including the southwest and northwest of the Country) had decreased heat waves. Cold waves, in most parts of the country, have a Positive TREND. However, about 25 percent of the study area's cold waves have a negative TREND. they are located in areas higher than Latitude 30°. The largest decline of the wave's TREND along the country is highlands. Nowadays, most of the country, has a TREND between 0.01494 and 0.00828 ° C, respectively. Conclusion Common changes and effects of heat and cold waves had a direct relationship in many parts of the country. It is remarkable common variance in the East reached 55 percent, according to statistical significance. In some areas of the northwest and southwest, which have been impressive heights, the common variance is 40 percent. This common variance in mountains area has been high values. Investigation of heat waves TREND shows that 65.8% of Iran significant positive TREND and 7.1% significant negative TREND. Also, the cold waves TREND has indicated a 48.5% significant positive TREND and a 10.8% significant negative TREND. Climate change and global warming have changed the frequency and severity of temperature extremes. The present study, by examining the number of warm waves, concluded that the warm waves have increased in magnitude in 65.8% of the Iran zone. Also, the study of the cold waves TREND showed that 48.5 percent of Iran had a positive TREND, which means that the amount of temperature in the cold waves increased In other words, the severity of the cold has been reduced And only 10.8 percent of Iran had a negative cold wave TREND And it shows the intensity of these waves is reduced.   Funding There is no funding support.   Authors’ Contribution The authors contributed equally to the conceptualization and writing of the article.

هدف اساسی این مقاله پژوهشی، بررسی ترجیحات فرزندآوری در بین گروه های قومی منتخب در ایران است. گروه های قومی این تحقیق، مشتمل بر اقوام ترک، ترکمن، کرد، گیلک، لر، لک، و مازنی است. یافته های این تحقیق نشان دهنده شباهت ها و تفاوت های قابل ملاحظه ای در بین گروه های قومی از نقطه نظر ترجیحات فرزندآوری آنها است: از یک سو، مهم ترین وجوه مشترک آنها این است که نه تنها هیچ یک از گروه های قومی مورد مطالعه تقریبا هیچ گونه ترجیح و تمایلی به الگوی بی فرزندی ندارند، بلکه بیشترین ترجیح آنها معطوف به الگوی دو فرزند است. از سوی دیگر، بیشترین تفاوت ها در بین گروه های قومی در زمینه ترجیحات فرزندآوری را باید در الگوی سه فرزند و بیشتر جستجو کرد. در مجموع، تجزیه و تحلیل های این تحقیق، مبین این نتیجه گیری نهایی است که هیچ یک از متغیرهای تحقیق، حتی سطح تحصیلات دانشگاهی نیز نتوانسته است یک نوع هم گرایی قومی در الگوی فرزندآوری زیاد یعنی ترجیح به داشتن سه فرزند و بیشتر را فراهم کند که به خوبی نشان دهنده این نکته مهم است که تعلقات قومی کماکان نقش بسیار مهم و تعیین کننده ای در ترجیح فرزندآوری زیاد ایفا می کند.

The ability of plant communities in natural ecosystems to modify temperature has become increasingly important due to the profound impacts of global climate change, particularly in arid regions. However, previous studies have provided limited information on the long-term temperature feedback of these plant communities and the biotic drivers behind these changes. This study aimed to determine the functional traits and types of plant communities as biotic drivers of land surface temperature (LST) at the plant community scale, with a focus on identifying co-functioning communities in the Sirjan region of Kerman Province. To achieve this, we utilized the MODIS-LST 8-day composite product at the plant community scale and measured functional traits of dominant species through field operations. The results revealed that leaf dry matter content (LDMC), maximum height (MH), and leaf width (LW) traits significantly reduce LST. Additionally, cluster analysis indicated that the plant communities in the study area can be classified into five functional groups, which fall into two co-function categories. The S-strategized co-function (e.g., 26 communities), characterized by high LDMC values and a combination of abrupt and TREND feedback in LST, was found to be more effective than the R-strategized co-function (e.g., 13 communities), which exhibited only TREND feedback. Therefore, it can be argued that extreme temperatures, as a global concern, can be mitigated through careful selection of vegetation based on functional traits and strategies. This approach, particularly through rangeland improvement practices using species such as Astragalus spachianus, Cornulaca monacantha, and Launaea acanthodes, could play a significant role in addressing this challenge.

The reception of Popper in Japan has not been a glorious history up to the present day. There have been numerous misunderstandings and distortions. It is important to record and discuss them in order to learn from them and to make use of his ideas in the Japanese intellectual climate. This is the purpose of the present paper. From the perspective of the reception history, we searched the reasons why Popper has been misunderstood in Japan (especially in four areas: philosophy, economics, history, and political philosophy), and tried to identify some of the factors responsible for this misunderstanding. To this end, we applied the method of “situational analysis” to the Japanese peculiar intellectual situation after the so-called après guerres, rather than by using a chronological order. If the causes of misunderstandings and distortions in Japan can be clarified by means of a situational analysis, we can learn a great deal from this history and can use this knowledge to throw new light on the status of critical rationalism in Japan

A B S T R A C TThe morphology of each region is related to its landforms, the morphology of flat areas is related to inselbergs. The presence of inselbergs in desert and dry areas gives a special appearance to the morphology of these areas. The study of these landforms and the effective factors in their formation is considered a necessity in terms of regional development. According to the studies, various factors play a role in the formation of inselbergs, and the role of lithology seems to be more prominent. In this research, which was conducted with the method of field and library studies, we identified 18 inselbergs in Safi Abad plain and by studying them, we came to the conclusion that the inselbergs of this plain are mainly formed in sedimentary rocks such as limestone, conglomerate and sandstone. Among the geological formations, the largest and most diverse inselbergs in the Safiabad plain are formed in the mass conglomerate formation with good hardening because this formation is the most widespread in this plain. But the most typical inselbergs of this plain are formed in thick layered limestone. Because this formation is more resistant to erosion. Lar Formations including Limestone and Thick Limestone’s to Mass Dolomite and Delichai Formations have also played an important role in the formation of inselbergs in this plain. Although the extent of these formations is not significant, but due to their significant resistance to erosion and being far from these processes, they have caused the formation of evolved inselbergs in this plainExtended AbstractIntroductionInselbergs are ridges with a height of less than 500 meters formed with a steep slope in the plains. Their resistance to erosion has caused them to be considered capable players in the morphology of arid and semi-arid regions. Due to their uniqueness in desert areas, these areas are of interest to tourists, and the economic situation of these areas can be improved by attracting tourists. The prominence of inselbergs in desert areas has caused researchers to pay attention to their studies, the most important of which are the studies of Pye in Kenya (1984), Nenonen in Finland (2018), Luiza in Brazil (2021), Laetitia in Africa (2019), and Mashaal in Egypt (2020). Although the conditions for inselberg formation are available in some areas of Iran, and these landforms have given a particular face to the morphology of this country, no significant study has been done on them so far. This research attempts to investigate the role of lithology in inselberg formation in Safi Abad Plain by using library and field studies. MethodologySafi Abad plain in the northeast of Iran and North Khorasan province and in terms of geographical coordinates between 36-˚ 48-05 to 36-22-55˚ North and 37-57˚ East to 36-˚ 37-08 It is located at 57-58-11 east. Field and library studies were used to study the inselbergs of this plain. The entire region was surveyed in 2 years in the field studies, and 18 inselbergs were identified. Then, the location and extent of their expansion were determined. In the morphometry that was done as a survey, the minimum height, length-to-width ratio of inselbergs, and their distance from each other were measured with GPS. The study of the concepts, definitions, and effective processes in inselberg formation was done with the library method. The maps of this research were drawn with Adobe Illustrator software. Results and discussionInselbergs are diverse in terms of morphology; in the studied area, 18 inselbergs were identified, most of which are mixed. Most of them are rocky and have less vegetation. Regarding lithology, inselbergs are particular forms of igneous and metamorphic rocks, but some are also formed in other rocks. Although lithology plays an essential role in inselberg morphology, it cannot be claimed that inselbergs formed in the same formation have the same shape. Although the dominant lithology of the Safi Abad plain is formed from sedimentary rocks, due to the different resistance of its formations, the height, shape, and slope of the inselbergs of this plain are different in different parts of the region. The difference in these characteristics has caused the different shapes of the land in this plain. According to the studies of the most resistant formations of Safi Abad plain against erosion, limestone is a thick layer of chert mass formed due to the resistance against the erosion of the complete inselbergs.After this formation, the Lar formation consists of fine-grained uniform dolomitic limestone with thick to massive layering, which is more resistant; that is why many inselbergs in the region have formed in it. The third formation in terms of resistance is the Apsin-Albin unit, which includes orbitolinate limestone and thick limes to a mass of dolomite. Although this unit has a small area, its inselbergs are closer to typical inselbergs. In terms of area, most of the area is composed of mass conglomerates with good hardening. Due to the different effects of this formation from different processes, its inselbergs do not have the same morphology. The inselbergs formed in this formation are in the middle part of the high area, low in the southern part, incomplete in the western part, and incomplete mushrooms in the path of the Gerati River. After this formation, gray shales are the most resistant to erosion. This formation, which belongs to the Jurassic period, has formed a large part of the northeastern inselbergs. The alternation of limestone and marl in the Delichai formations in the middle part of the region provides the basis for the formation of mushroom-shaped inselbergs in the future. ConclusionSafiabad Plain is in the northeast of Iran, and in terms of geomorphological units, it is part of central Iran. Inselbergs form part of the morphology of this plain. In this study, 18 inselbergs were identified in this plain, and their detailed study showed that their primary skeleton was established by tectonic activities in the Devonian to Miocene period with the formation of Posht Bahram mountains. It was formed when the tectonic activities calmed down and in opposition to the lithology and erosion of the inselbergs of this plain. In terms of lithology, the well-hardened conglomerate formation covers nearly 47% of this plain, and due to its large size and different distances from erosion processes, various inselbergs have been formed in it. The southern inselbergs formed in this formation have a regular shape due to wind and blue erosion. In contrast, the middle inselbergs have an incomplete shape due to the distance from higher erosion, and the western inselbergs have an incomplete shape due to the superiority of blue erosion. Another formation that plays a vital role in this field is Lar Mei Formation. Although this is the second formation in terms of size and strength, many inselbergs have formed in it. The Shemshak formation is placed after the Lar formation in terms of resistance. This formation has caused the formation of chain inselbergs in the northeast of the region. The most typical inselbergs of the region are observed in the thick layered limestones of the formation (Maastrichtian). Also, this research found that inselbergs may be formed in all flat areas of the world and even in sedimentary formations. However, the inselbergs formed are far from those formed in tropical regions' igneous and metamorphic formations. FundingThere is no funding support. Authors’ ContributionThe authors contributed equally to the conceptualization and writing of the article.
