Demírel, Ugur; Çam, Handan
This study investigates public sentiment about popular cryptocurrencies listed on crypto exchanges in Turkey, using comments shared on social media platforms and online forums. The research seeks to enhance the existing body of knowledge by overcoming the shortcomings of sentiment analysis studies focused on Turkish texts. Data collected from social media and online forums were examined with sentiment analysis techniques. A total of 607,592 comments were analyzed, of which 89,986 were classified as negative, 72,655 as positive, and 444,951 as neutral. For binary classification, 89,986 negative and 72,655 positive examples were selected and machine-learning models were trained and tested on 162,641 examples. The study's methodology includes an in-depth examination of sentiment analysis results obtained using machine learning classifiers. The findings show how various cryptocurrencies are perceived on different social media platforms. For instance, BTC (Bitcoin) is generally perceived negatively on Investing.com and Telegram, while ETH (Ethereum) generally displays more negative views. These results help investors understand their perceptions and market expectations towards cryptocurrencies. This study deepens the role of social media sentiment analysis in cryptocurrency markets, contributing to the development of new methods and approaches for future research.

Ozyurt, E.
This study numerically investigated the elevated temperature resistance of earthquake-damaged square hollow section (SHS) T-joints subjected to brace axial compressive load. The residual stresses and deformations due to the earthquake were obtained from a pushover analysis. The extensive numerical simulations were analyzed using nonlinear finite-element software to examine the effects of the beta ratio, gamma ratio, damage level ((D) over cap), and initial applied load (n(f)) on the fire resistance of SHS T-joints after verification of the numerical simulations based on the available test results in the literature. The results indicated that the fire resistance of SHS T-joints with axial compressive load in the brace member decreased significantly due to the residual stresses and deformations from the earthquake. This situation worsened in all numerical models as the damage level increased. The reduction rate of the critical temperature at various damage rates was independent of the initially applied load ratio, but the loading rate directly affected the fire resistance of the joint regardless of the earthquake. As the beta ratio decreased, the yielded area at the brace-to-chord intersection region increased. Thus, the critical temperature of the joints at a constant damage level was inversely proportional to the beta ratio. Joints with a large gamma ratio had larger residual stresses and deformations than those of corresponding joints with a small. ratio. Therefore, the fire resistance of the joints after the earthquake decreased as the chord-wall thickness decreased. The critical temperature of the joints with either a large beta or gamma ratio was limited by the deformation limit at high damage levels. The fire resistance of the SHS T-joints after the earthquake decreased due to residual stresses and deformations. That effect increased even more in joints with high beta and. ratios.

Balik, Emrah
One of the educational methods emphasized and applied by the Qur'an is the use of parables. In this context, there are many stories of prophets, individuals and communities in the Qur'an. The inclusion of parables in the Qur'an serves a number of purposes. In this regard, there is a strong similarity between the purposes of parables and the purpose of the Quran's revelation, primarily to ensure that people take lessons. This is because the Qur'an includes the historical experiences of past prophets and nations through parables when it talks about individual issues and social events that concern human life. Qur'an emphasizes that within the stories of past prophets and communities, there are numerous lessons for people of understanding, and these are not fabrications but sources of mercy and guidance for believers. As a source of guidance for believers, the Qur'an aims to give people a new faith through parables, to lead them away from superstitious beliefs, in short, to change their lives. Based on this feature, Qur'anic parables have an important position in terms of values education. Undoubtedly, one of the methods that can be utilized in values education is the method of education through storytelling/narratives. Indeed, the Qur'anic parables are witnesses to the existence of values such as good, right, beautiful, lawful, etc. since Adam. Because narratives are as ancient as human history itself. In this respect, the many different role models and examples of positive and negative behaviors interspersed in the Qur'anic parables allow people at all levels to draw their own conclusions. The dramatic narratives about the roles represented by the different characters mentioned in the parables and the consequences of the behaviors arising from these roles lead to permanent changes in attitudes and behaviors in the addressees. In this context, each parable in the Qur'an is important in terms of values education. In this context, the parable of Lot is a parable that should be meticulously emphasized and analyzed in terms of its aim to impart a set of moral principles and virtues to today's individuals and societies. Indeed, the fact that the scope of the impact of Quranic parables is not limited to the societies in which they occurred historically, but also encompasses dimensions relevant to today's individuals and societies, underscores the necessity of examining the story of Prophet Lot from the perspective of values education. In this context, the subject of the article was determined as Analysis of Negative Attitudes and Behaviours Mentioned in the Parable of Prophet Lot in the Qur'an in terms of Values Education. Prophet Lot, during his forty years of prophethood, forbade his people, who were sinful and committed many evils, especially homosexual intercourse between men, from disobeying Allah Almighty, and invited them to the consciousness of servitude and obedience to Allah. In this context, the parable of Prophet Lot in the Holy Qur'an is a parablethat deals with individual and social morality and presents the related issue in a perfect style. According to the account narrated in this parable, the vile behaviors exhibited by the people of Prophet Lot (peace be upon him) illustrate how the mentioned society trampled upon individual and societal ethics. Even today, some individuals and societies abuse similar moral principles and virtues. In such cases, it is a social responsibility to remind people of the experiences of individuals and societies in the past who have disregarded these moral principles and virtues, and to help them draw a series of instructive conclusions. In this regard, fulfilling sexual needs within the framework of halal, as in every human need, is one of the issues that Islam insists on. In this context, it is also important to identify the negative attitudes and behaviors mentioned in the parable of Lot in order to inculcate a world life based on faith and ethics in today's individuals and societies. Only in this way can people learn the necessary lessons from the past and be protected from the same or similar immoralities.

Gökçür, Uyesi Engin
Suffixes -(I)p and -(U)p have been used as verbal adverb suffixes during the historical development of Turkish language. When these suffixes are added, verbs modify the central meaning in terms of 'situation, time and style.' Therefore, they are used instead of the verbal adverb suffix (- arak), not used in Turkmen Turkish, that is used to refer to situation and style. These suffixes mostly form verbal adverbs stating situation and style with their function mentioned above in Turkmen Turkish. Besides, when they are added to verbs, they form descriptive verbs by attaching verbs to auxiliary verbs. In this case, it has been seen that they take role in the formation of descriptive verbs that refer to sufficiency, quickness, duration, process, ending and starting. As these suffixes have the function of attaching completed conclusions to another conclusion, they have lost their verbal adverb function in time in Azerbaijani Turkish as in Turkmen Turkish and have been used as past perfect tense. These suffixes are used especially in second-person singular and plural in past perfect form in Turkmen Turkish. They are used in the form of past perfect tense when followed by the (- dir) affix.

Recepoglu, Mursit
This study has examined the causality relationship between public expenditures, economic growth and income inequality for transition economies called the Commonwealth of Independent States (CIS). In the study, in which the 1998-2019 period was analyzed, the effects of public expenditures on economic growth and income inequality were determined with the bootstrap panel causality test. Bootstrap panel causality test results show that there is a one-way causality relationship from public expenditures to economic growth for Armenia, Belarus, and Kazakhstan. On the other hand, a one-way causality relationship has been determined from public expenditures to income inequality in Belarus and Kazakhstan, and from income inequality to public expenditures in Kyrgyzstan. In Moldova and Russia, however, no causal relationship could be obtained between the variables. The overall evaluation of the findings obtained from the panel causality tests concluded that public expenditures in CIS member countries are closely related to both economic growth and income inequality. CIS member countries need state interventions in order for the market system to fully settle in transition period. However, implementing policies that do not exclude private investments and do not harm the functioning of the market economy should be elaborated during practicing public expenditure policies in these countries in transition.

Yalcin, Numan; Dedeturk, Mutlu
In this study, we develop a systematic framework for anageometric calculus as an extension of non-Newtonian analysis. Fundamental concepts, including limits, continuity, differentiation, and higher order derivatives, are established, and the connection to classical calculus is clarified through a logarithmic transformation. Within this framework, we derive the properties of the anageometric derivative, inverse function relations, partial derivatives, and mean value theorems. The theory is extended to integration by establishing the first and second fundamental theorems of anageometric calculus. Furthermore, the structural implications of the anageometric derivative are investigated, demonstrating that the equation D similar to f=lambda f naturally generates power-law solutions rather than classical exponential ones. This highlights the suitability of anageometric analysis for scale-invariant phenomena and proportional growth processes, supported by a practical heat-conduction example.

Aydin, Aydanur
In the event of a natural disaster, women who assume multiple roles within the family unit tend to postpone their health concerns and delay medical appointments. The present study aims to examine the relationship between the level of fear of breast cancer and the implementation of breast cancer preventive behaviours among women following an earthquake. The sample consists of 2,671 women aged 20 and over who participated voluntarily. The data were collected using two instruments: the Breast Cancer Fear Scale and the Women's Breast Cancer Prevention Behaviors Form. Following a comprehensive review of the extant literature, it was determined that women affected by earthquakes exhibited elevated levels of fear of breast cancer. A substantial decline was observed in the utilization of preventive measures necessitating institutional access, including mammography. The findings of this study indicate that education, occupation, and family history of breast cancer have a significant impact on women's post-earthquake fear levels in implementing preventive behaviours. However, given the cross-sectional design and the absence of pre-disaster baseline data, these findings reflect post-earthquake associations rather than temporal or causal trends. Natural disasters can result in the deterioration of health perceptions, exacerbated by heightened stress and health concerns. Consequently, there is an urgent need for innovative approaches to ensure the maintenance of health check-ups and continuous access to preventive care in the aftermath of large-scale natural disasters.

Çakir, Tufan; Dag, Serhat
The Mononobe-Okabe (M-O) method based on limit equilibrium principle is widely used in the design of retaining structures against earthquake loads. However, this method does not consider the soil-structure interaction and wave propagation effects. On the other hand, it is known that the interactions of retaining structures with backfill and foundation soils transform the seismic behavior of these structures to a rather complex problem. The main purpose of this study is to evaluate the soil-structure interaction and wall flexibility effects on the seismic behavior of backfill-cantilever retaining wall-foundation/soil systems. In line with this target, three dimensional finite element models were utilized for analyzing the aforementioned systems. Seismic analyses were carried out in the time domain by considering five different foundation soil conditions and two different wall thicknesses. The results were comparatively interpreted in terms of lateral wall displacements and the stresses occurring at critical sections of the wall. It was observed that these responses may vary significantly due to soil-structure interaction and wall flexibility effects.

Demir, Sertac Timur
This paper is basically about nowism as a representation of modernity rather than a temporal fragment, about cancer as philosophical reference rather than as a biological illness, and about death as constructive value rather than as a destructive experience. All these representation-loaded concepts are dealt with through the story of Tessa, the protagonist in the film Now is Good (2012). In the liquid modernity, on the one hand nowist orientations, tendencies and acts are wryly reduced to a cliche: Carpe diem (seize the day) and on the other hand temporal uncertainty of death implies the essential principle of memento mori (remember you will die) or Mutu qabla an tamutu (die before you die). The now is, as a worldview beyond a temporality, not merely good, but perhaps the God of the modern society. However, deadly cancer, which is an uninvited guest, nullifies this modern doctrine that commercializes the now as eternity and immortality itself. Cancer that marks death and the sense of chaos what cancer stirs are antithesis and perhaps antidote of the liquid modernity. This paper, for the very reason, unexpectedly affirms death while criticising the nowist culture.

Sipahi, Ferkan
Skarn deposits are located in the NE Black Sea region of Turkey belonging to the Alpin metallogenic province. The Fe skarn deposit at Arnastal is hosted by Late Cretaceous carbonate rocks comprised of limestone and the skarn occurrence at Camibogazi dolomitic limestone, adjacent to the Eocene Zigana Granitoid. The prograde textures include rhythmic banding, spots, and mossiness, and the retrograde textures are shock-induced and brecciated. These are identified in the Fe skarn deposit at Arnastal, where there are mineral parageneses of andradite, actinolite, tremolite, epidote, quartz, magnetite, and hematite, and less pyrrboune and pyrite. Additionally, well-crystallized vesuvianite, well-crystallized phlogopite, and diopside in the skarn occurrence. at Camibogazi are identified. Some of the skarn minerals are calcic and have high Mg/(Mg + Fe) ratios. Clinopyroxene consists of diopside (Di(96.66-99.04)Hd(0.67-2.80)Jo(0.29-0.55)). Vesuvianite is mostly Mg-rich, and has a very low MnO content (<0.1 %). Other skarn minerals are Fe-rich. Garnet is characterized by oscillatory zoning and has an andradite composition (Ad(72)Gr(28) to Ad(98)Gr(2)). Epidote has an Fe content of 8.96 to 12.42 wt%. Magnetite is generally massive and sporadically banded with some martitization. The formation temperatures of skarn minerals range from 330 to 600 degrees C. In addition, mass change calculations from the granitoid and andesite toward the skarn zone indicate that there is considerable mass transfer of Si, Al, Fe, and Mg to the carbonate rocks during skarn formation. The average mass changes are estimated at a depletion of 41 g/100 g in granitoid and a gain of 8 g/100 g in andesite. Fe skarn deposit and skarn occurrence are characterized by early, high-temperature mineral assemblages dominated by the anhydrous minerals garnet and diopside and late low-temperature assemblages with hydrous minerals, such as vesuvianite, phlogopite, and epidote. The type of garnet and the abundance of magnetite with minor pyrite suggest that the Fe skarn deposit at Arnastal forms under relatively oxidized conditions. The type of clinopyroxene in the skarn occurrence at the Camibogazi shows oxidized skarns.
