Time constraints on the geological evolution of the main sedimentary basins and tectono-magmatic events on Livingston Island, South Shetland Archipelago, Antarctica: a review
Authors: Georgiev Stoyan , Velev Stefan , Dochev Docho , Metodiev Stefan , Balkanska Eleonora , Sabeva Ralitsa , Georgiev Neven
Published: September 2023

The Lower Cretaceous to Miocene South Shetlands Islands’ volcanic arc is a result of the subduction of the Phoenix Oceanic Microplate (part of the Pacific Plate) beneath the Antarctic Peninsula. The magmatic activity on Livingston Island has been going on for a long time: since the Early Cretaceous to the present. The evolution of the volcanic arc resulted in the formation of various sedimentary basins and paleoenvironments (turbiditic to shallow marine and continental) that formed varied sedimentary successions and tholeiitic to potassium calc-alkaline subduction-related magmatic rocks. Considering the magmatic activity on Livingston Island, a general trend of rejuvenation can be observed from the WNW (Byers Peninsula) to the ESE (to Hannah Point, Point Williams and further to the Hurd Peninsula and the Tangra Mountain). The rejuvenation of the magmatic rocks in the direction of the thrust plate can be explained as an effect of a flattening subduction that was active from the Early Cretaceous (135 Ma) up to around 90–70 Ma. The mixed ages of the dikes and small intrusions in the Hurd Peninsula are most probably due to periods of rotation and probably beginning of а slab-roll back. A regional Paleocene–Eocene (65–47 Ma) compressional episode that caused a low temperature to high-pressure metamorphism is registered on Smith and Elephant islands. The regional metamorphism was followed by a vast extension between 50–30 Ma that culminated with the opening of the Drake Passage around 34–30 Ma. The magmatic response of that regional scale extension was the intrusion of the Eocene Barnard Point Pluton (46–40 Ma) and dikes with youngest ages of around 30 Ma. The major uplift phase and the exhumation of the Tangra Mountain happened between 22–16 Ma as indicated by the Ap FT thermochronology. The last magmatic event on the island produced the contrastingly different in composition Quaternary alkaline mafic rocks that occupy the area between Innot Point and Burdick Peak. This episode is interpreted as related to a process of crustal extension that culminated in asthenospheric upwelling and rifting along the Bransfield Strait. The latter is due to a slab roll-back that led to the break-up of the South Shetlands from the Antarctic Peninsula and consequent subduction termination.

In the current study, 3-formyl phenyl benzenesulfonate is created by reacting 3-hydroxybenzaldehyde with benzene sulfonyl chloride, which is aided by triethylamine. Nine unique (Z)-3-[(3-substituted-5-oxo-1,5-dihydro-4H-1,2,4-triazol-4-yl)-iminomethyl] compounds were formed through the reaction of a manufactured 3-formyl phenyl benzenesulfonate chemical with nine 3-alkyl(aryl)-4-amino-4,5-dihydro-1H-1,2,4-triazol-5-one, as detailed in the existing literature. Phenyl benzene sulfonate (S) compounds were purchased. Through the reaction of the Schiff bases that were made a secondary amine, such as morpholine with formaldehyde, heterocyclic Mannich bases of a unique kind were created. Five recently found (Z)-3-[(3-substituted-5-oxo-1,5-dihydro-4H-1,2,4-triazol-4-yl)-iminomethyl] compounds are presented in this work. By reacting phenyl benzene sulfonate (S) with morpholine in the presence of formaldehyde, five new (Z)-3-[(3-substituted-1-(morpholinomethyl)-5-oxo-1,5-dihydro-4H-1,2,4-triazol-4-yl)-iminomethyl] compounds were created. Chemical compounds fall under the category of phenylbenzene sulfonates (M). Utilizing IR, 1H NMR, and 13C NMR spectroscopy, fourteen recently novel compoundsand#39; chemical structures were examined. The ability of the freshly synthesized Schiff and morpholine-derived Mannich bases to obstruct the acetylcholinesterase enzymeand#39;s (AChE) activity was also assessed. The 1,2,4-triazole functional group was modified by adding various groups at the 1 and 3 positions, resulting in a collection of compounds (S1–9 and M1, 2, 4, 5, 7). It was determined whether these synthetic compounds could prevent the human recombinant AR enzyme from working in vitro, and the findings were validated using molecular docking, molecular mechanics, and ADME analyses. To better understand this mechanism, synthetic Schiff and Mannich base derivatives as well as the positive control substance quercetin were tested using molecular docking against the human recombinant AR enzyme in vitro. To assess the drug-like properties of Schiff and Mannich base analogs, a series of absorption, distribution, metabolism, and excretion (ADME) properties were analyzed theoretically.
Trauma in the movie Ordinary People (1980): An investigation of psychological trauma and recovery from a traumatic experience
Authors: Umer Hajra , Aziz Sabah
Published: September 2023

Trauma theory is an emerging field that is interdisciplinary and incorporates both psychological and physiological studies related to trauma. The main focus of trauma theory is the exploration of the workings and effects of post-traumatic stress disorder (PTSD). Embedded in the trauma theory, this research aims at carrying out a qualitative analysis in order to explore the workings of trauma and recovery from traumatic experience. The study shall deal with analyzing Conrad’s character in the movie Ordinary People (1980) by evaluating different behavioral patterns exhibited by him in the movie. In order to explore the working of trauma, the study shall utilize the diagnostic criteria provided by the American Psychiatric Association (2013) that lists the symptoms related to traumatic disorder. In order to explore the process of recovery, Herman’s three stage model (1992) of recovery from trauma is utilized. The research findings conclude that Conrad’s character suffers from trauma exhibiting most of the symptoms listed in the diagnostic manual. These symptoms include nightmares, flashbacks, intrusive thoughts, isolation, irritability etc. The findings also show that Conrad’s character successfully undergoes all three stages of recovery. He transforms into an emotionally stable individual after the recovery process occurs. The study has made use of the film medium in order to create awareness about the trauma related issues focusing on the role of professional and social help for traumatic individuals.
Presentation of Racial Discrimination: A Transitivity Analysis of Meghan Markle’s Interview at The Oprah Winfrey Show
Authors: Haque Rabail , Janjua Fauzia
Published: September 2023

The transitivity analysis of Meghan Markle’s interview at “The Oprah Winfrey Show” has been carried out to see how the experience of racial discrimination has been presented in language.  It is descriptive-qualitative research where Hallidayan Transitivity Model, from SFG, has been employed to explore the meanings construed in utterances.  SFG looks at the functions of language and transitivity deals with experiences narrated and conveyed through language.  The analysis of the data reveals that the utterances construe an experience of racism as Meghan had a Black American identity.  Her unborn child was mocked for his/her complexion, and was denied security, title, and an equal status in the Royal family.  She also experienced bullying at the international level through international media and had to leave the UK.  The most dominant processes found through the analysis are mental and verbal processes.  The mental processes show that she understood, perceived, and therefore got affected by racism.  The verbal clauses show that she was bullied, verbally, and questioned by the family.  While the material and behavioural processes show her effective response towards racism and discrimination based on that racism, while the relational clauses identify it.  The language is highly objective since circumstances are used thereby bringing validity and detail to her experiences.

Published: September 2023

In the current study the socio-psychological analysis of The Lion of Kashmir (2020) by Siddhartha Gigoo's is done by using the prism of socio-psychological theory and the theoretical notion of psychoanalytical theory. According to the researcher, the novel's protagonist has a disturbed mental state brought on by violence. There many elements which can induce mental disturbances. These elements include frequent bombardment, a shortage of basic amenities in contested regions, homelessness, the murder and kidnapping of family members, and others. The study also looks at how the victims of this mental disorder suffered from inferiority complexes and self-shattering. The novel's author provides a window into the protagonist's mind and paints a vivid picture of his anxieties. The narration's phantasmagoria offers us several perspectives on the story. This analysis supports the idea that the selected novel of Gigoo emphasizes life is difficult  for Kashmiris.
Perceptions of Undergraduate ESL Learners towards Syntax Contents & Teaching Methodology
Authors: Hussain Bilal , Mehdi Muntazar
Published: September 2023

Syntax is one of the important branches of theoretical linguistics that deals with the study of structural constructions of various languages. However, learners often find studying and internalizing the contents of syntax a challenging and daunting task. To address this issue, mixed-method research was conducted to evaluate the perceptions of fifty non-randomly selected sixth-semester undergraduate ESL students with reference to the course contents and teaching methodology. The survey research design was employed, and the data were collected through a comprehensive questionnaire. Findings reveal that most learners studied grammar at schools and colleges through the deducted approach. This grammar background has enabled them to grasp course contents of syntax rather effortlessly. Moreover, the learning process was facilitated by comparing English syntactic constructions to those of the Urdu language in addition to the structures of other languages. However, there are some topics that learners find somewhat laborious and challenging to internalize. These contents include tree diagrams, structural ambiguity, forms and functions, phrase structure rules, and X-bar rules. Personalized instruction and extensive practice can make these course contents less challenging. The learners generally have felt their overall satisfaction with the teacher's interactive and learner-centered teaching methodology.
Development and evaluation of the gender-specific CONSTANCES job exposure matrix for physical risk factors in France
Authors: Wuytack Francesca , Evanoff Bradley A , Dale Ann Marie , Gilbert Fabien , Fadel Marc , Leclerc Annette , Descatha Alexis
Published: September 2023

OBJECTIVES: This study aimed to construct and evaluate a gender-specific job exposure matrix (JEM) for 27 physical work exposures, based on self-report.

METHODS: We constructed a JEM using questionnaire data on current physical exposures from 29 381 male and 35 900 female asymptomatic workers aged 18–69 years in the French CONSTANCES cohort study. We excluded workers with musculoskeletal pain to reduce potential reporting bias. We grouped 27 self-reported physical exposures using the French national job codes and stratified by gender. We compared individual and group-based exposures using the performance indicators Cohen’s kappa (κ), sensitivity, specificity, and area under the receiver operating curve (AUC).

RESULTS: JEM validation showed fair-to-moderate agreement (κ 0.21–0.60) for most physical exposures for both genders except for ‘reach behind’ (poor), ‘bend neck’ (poor), ‘finger pinch‘ (poor), standing’ (good), ‘use computer screen’ (good), and ‘use keyboard or scanner’ (good). We found the highest AUC for ‘standing’ (men 0.85/ women 0.87), ‘kneel/squat’ (men 0.80/women 0.81), ‘use computer screen’ (men/women 0.81), and ‘use keyboard or scanner’ (men 0.82/ women 0.84). The AUC was <0.60 for only three exposures: ‘bend neck’ (men 0.58/women 0.57), ‘finger pinch’ (men 0.56/ women 0.55), and ‘reach behind’ (men 0.54/ women 0.51).

CONCLUSION: The constructed JEM validation measures were comparable for men and women for all exposures. Further research will examine the predictive ability of this gender-specific JEM for musculoskeletal disorders and the relevance of gender-stratification in this process, knowing accuracy of each exposure.

Towards zero downtime: Using machine learning to predict network failure in 5G and beyond
Authors: Basikolo Emmanuel , Basikolo Thomas
Published: September 2023

A stable network is very important to both network providers and their customers, as it increases reliability, improves security and helps customers and companies save costs. When network outages occur, they result in significant downtime and financial losses for organizations and network users. Traditional methods of detecting and troubleshooting network failures are often reactive and time consuming, whereby network administrators rely on traditional methods such as reactive monitoring and manual troubleshooting. These methods are often not effective in detecting and preventing network failures. In this paper, we propose a machine learning-based approach to predict network failures and minimize downtime. Network performance observability data from a 5G core network testbed based on Cloud-native Network Functions (CNFs) is used to train several supervised learning models, including random forest, gradient boosting regressor, conventional support vector regressor and proposed support vector regressor, to predict network failures. Our experiments and analysis show that the proposed model Support Vector Regressor (SVR) produced better results as compared to other models. In a very short amount of time (ten seconds), the proposed SVR model is capable of predicting whether a network failure event will occur or not within the next ten minutes, with an f1-score of more than 0.9. Our results indicate that machine learning-based approaches can significantly enhance the detection and prediction of network failures, leading to zero downtime and improved network performance.

Published: September 2023

In order to verify the security of the Z-Wave communication protocol, the possible attacks in the protocol are analyzed to reduce user privacy security vulnerabilities. For the communication process and key exchange process between the controller and the node, this paper uses CPN tools to model the Z-Wave S2 protocol, and introduces the Dolev-Yao attack model to verify the security behavior of the protocol. The results show that there is a man-in-the-middle attack when using S2 authentication for device inclusion. In response to this vulnerability, we propose a lightweight static authentication scheme based on HKDF function and XOR operation, which performs authentication between Z-Wave controller and slave device. Secondly, we formally verify the security objectives of the improved scheme, and prove that the optimization scheme can effectively prevent man-in-the-middle attacks in the S2 security mode.

 
Estimation on Human Motion Posture using Improved Deep Reinforcement Learning
Authors: Wenjing Ma Wenjing Ma , Wenjing Ma Jianguang Zhao , Jianguang Zhao Guangquan Zhu
Published: September 2023

Estimating human motion posture can provide important data for intelligent monitoring systems, human-computer interaction, motion capture, and other fields. However, the traditional human motion posture estimation algorithm is difficult to achieve the goal of fast estimation of human motion posture. To address the problems of traditional algorithms, in the paper, we propose an estimation algorithm for human motion posture using improved deep reinforcement learning. First, the double deep Q network is constructed to improve the deep reinforcement learning algorithm. The improved deep reinforcement learning algorithm is used to locate the human motion posture coordinates and improve the effectiveness of bone point calibration. Second, the human motion posture analysis generative adversarial networks are constructed to realize the automatic recognition and analysis of human motion posture. Finally, using the preset human motion posture label, combined with the undirected graph model of the human, the human motion posture estimation is completed, and the precise estimation algorithm of the human motion posture is realized. Experiments are performed based on MPII Human Pose data set and HiEve data set. The results show that the proposed algorithm has higher positioning accuracy of joint nodes. The recognition effect of bone joint points is better, and the average is about 1.45%. The average posture accuracy is up to 98.2%, and the average joint point similarity is high. Therefore, it is proved that the proposed method has high application value in human-computer interaction, human motion capture and other fields.

 
A Dynamic and Fine-Grained User Trust Evaluation Model for Micro-Segmentation Cloud Computing Environment
Authors: Chaoqun Kang Chaoqun Kang , Chaoqun Kang Erxia Li , Erxia Li Dongxiao Liu , Dongxiao Liu Xinhong You , Xinhong You Xiaoyong Li
Published: September 2023

With the diversity and complexity of user access behaviors in the “micro-segmentation” cloud computing environment, it is no longer possible to control unauthorized access of authorized users by only relying on user identity login authentication to control user access to cloud resources. The existing trust evaluation methods can not cope with the characteristics of “micro-isolated” cloud environment, which is characterized by high granularity of resources, increasing number of users’ access requests and rapid changes. Based on the zero-trust principle of “Never trust, al-ways verify”, we propose a dynamic, fine-grained user trust evaluation model for micro-segmentation cloud computing environment, which combines multiple user trust attributes and leverages the subjective-objective approach to assign weights to trust attribute indicators to achieve dynamic scoring of users’ real-time behaviors. To capture the characteristics of users’ intrinsic behaviors, we use correlation analysis to identify the correlation between users’ current and historical behaviors, and combine sliding windows and penalty functions to optimize the model. The massive simulation experiments demonstrate the effectiveness of the proposed dynamic and fine-grained method, which can effectively combine the intrinsic correlation of users’ own access behavior and the difference of access behavior among different users.

 
Sweetness and Flour: A Biopolitical Fable of the Sixteenth Century
Authors: Schwartz Ana
Published: September 2023

Following recent research in cultural studies that has observed “the emergence of biopolitics in the Americas,” this article proposes a new aspect to the early modern experience of eating. Rather than simply a vehicle for pollution, eating appears in the 1555 captivity of the Hessian adventurer and autobiographer Hans Staden by Tupinambá in Brazil as a flashpoint for techniques of coercive self-governance. Working as an arquebusier on early Portuguese sugar plantations, Staden witnessed the dangerous sweetness of early modern capitalism. Yet Staden’s keen sensitivity to the political economy of cassava root flour, a commodity on which he himself depended, also suggests he witnessed his own unhappy conscription into a regime that required him to discipline himself in order to survive. Staden’s frustrated memories showcase biopower’s surprisingly intimate, personal, reach, revising our understanding of modernity as altogether distinct from the feudal past.
Gold Links: Teaching Culture through Commodity Chains
Authors: Bruhn Heather McCune , Townsend Sarah J.
Published: September 2023

This co-authored article offers reflections on the pedagogical potential of focusing on commodity chains as an approach to teaching culture. By way of example, it foregrounds gold, drawing on the two authors’ experiences teaching material related to this valuable mineral in very distinct fields: European art history (in courses on the ancient and medieval eras) and Latin American literature and culture (in courses about the Amazon taught in Spanish and Portuguese). The authors also discuss their collaborative work in creating an Open Educational Resources (OER) module on gold, and the possibility of a co-taught course. Gold is a particularly interesting commodity given the many myths that surround it, its history as a form of currency and standard of value, and the aesthetic qualities attributed to it. More generally, however, focusing on specific commodities from the point of extraction to their use in an array of products encourages students to think about the materiality of culture and its implication in an array of political, economic, and ethical issues. It also offers a way of charting connections and differences across long arcs of time, across geographical space and cultural differences, and across different academic disciplines.

A “Deák School of History”
Authors: Judson Pieter M.
Published: September 2023

This article argues that—fully unintentionally—István Deák founded a distinctive school of history among the students he mentored. The school took inspiration from Deák’s captivating style, clear argumentation, and empathetic moral capacity. In particular, however, Deák and his students sought explanations for social, cultural, and political phenomena in East Central Europe outside the constricting boundaries of the nationalism that dominated this field of history. Before Benedict Anderson, Eric Hobsbawm, and Ernest Gellner revived constructivist theories of the nation from very different perspectives in the 1980s, Deák’s wary approach to nationalism and the Habsburg monarchy would become a key element that defined the school of historians that grew up around him. In doing so he and they radically reshaped our understanding of the region and its history.
Writing Gender into the “István Deák School of History”
Authors: Wingfield Nancy M.
Published: September 2023

This contribution discusses István Deák’s influence on the rapidly expanding field of gender in Habsburg Central Europe. While Deák did not employ gender as a category of analysis in his own work, some of the categories he did analyze, including collaboration and resistance, war and retribution, and the Habsburg military, and the way he analyzed them, often with a focus on social history, helped open the way for some of his students to move into the newer field of gender and sexuality.
István Deák: A Historian Who Cared about the Jews
Authors: Rozenblit Marsha L.
Published: September 2023

This article will demonstrate how the Habsburg historian István Deák always paid significant attention in his scholarship to the role of Jews in Central European society. In his first book on left-wing intellectuals in Weimar Germany, his 1979 study of Louis Kossuth, the leader of the Hungarian revolution of 1848, his magnum opus on the Habsburg army officer corps (1990), and his later work on collaboration and resistance in Nazi-occupied Europe, Deák revealed much about both the assimilation of Jews into European society and their rejection by that society. In his book on Kossuth, Deák demonstrated the ambivalence of the revolutionaries, whose liberalism impelled them to emancipate the Jews at the same time as many thought them incapable of Magyarization. Ultimately, it was Jewish loyalty to the Hungarian cause that made the Hungarian revolutionaries extend equal rights to the Jews. In his book on the army officers, Deák clearly demonstrated how the late Habsburg army refused to allow anti-Jewish prejudice to flourish. Unfortunately, many Habsburg Jewish officers were deported to the death camps during World War II.

Reading Gertrude Stein for Pleasure: Finding the “Mere Humor” in “High Modernism”
Authors: Shermyen Sarah
Published: September 2023

High modernist poetry, particularly Gertrude Stein’s 1923 poem “If I Told Him: A Completed Portrait of Picasso,” is often considered impenetrable and distinct from Stein’s more clearly humorous prose work. However, the poem invites us to laugh at the chaos of our world through the chaos and instability of language. This article explores the poem’s humor and the possibilities for pleasure it offers through the rhythm of repetition. Stein’s playfulness points to an oft-overlooked aspect of high modernism: its appeal to our most visceral selves.
Challenging Stereotypes: Prosocial Racial Humor in Luís Valdez’s Actos
Authors: Hama Mark
Published: September 2023

This article examines how Luís Valdez uses prosocial racial humor in his collection of short plays to challenge the anti-Mexican racism directed against the strikers during the 1965–1970 Delano, California, grape strike as well as to address many of the other social issues faced by the Chicano community during this period. Drawing on social psychology research on the dynamics of racial group identification and focusing on the acto entitled Los Vendidos, the article analyzes how Valdez and his Teatro Campesino created the set of conditions that allowed audience members to confront and overcome the negative effects of the racial stereotyping and ethnic slurs they were experiencing on the picket lines and elsewhere and in the process to raise their Chicano cultural and political consciousness.
When the Community of Laughter Needed the Bathroom: Bridesmaids and the Limits of Cringe Comedy
Authors: Schwanebeck Wieland
Published: September 2023

This article links the concept of the community of laughter to cringe comedy, which emphasizes embarrassment, awkwardness, and social isolation over the affirmative bonds of other, less pain-inducing branches of comedy. It uses the film Bridesmaids (2011) to investigate how cringe comedy refrains from celebrating communality and solidarity, exposing the fragility of female bonds in the context of class warfare. The film’s eloquent and cringeworthy set pieces isolate the main character from her potential “community of laughter” and set her on a trajectory that is often closer to the arc of tragedy, where characters experience a fall. Crucially, cringe comedy’s inherent necessity to soften the blow, signaled by the climactic reconciliation in Bridesmaids, is not to be confused for a cop-out on behalf of the filmmakers. It is part of cringe comedy’s tendency to set its main characters on a path towards catharsis and spiritual betterment.

En la actualidad uno de los problemas dentro de los ambientes atemperados, es el hecho de aprovechar el espacio al mismo; frente a ese problema se planteó el presente trabajo titulado: Evaluación de diferentes marcos de plantación en dos variedades de espinaca (Spinacea oleracea L.) en el Centro Experimental Cota Cota, realizado en un ambiente atemperado, perteneciente a la Facultad de Agronomía, Campus universitario de la Universidad Mayor de San Andrés; donde se evaluó el desarrollo de dos variedades de espinacas bajo diferentes marcos de plantación, además de determinar el rendimiento y realizar un análisis económico de la producción. Realizándose en un invernadero de una superficie de 31,32 m2 de área utilizable. Las dos variedades empleadas (Quinto y Viroflay) fueron evaluadas; lográndose los siguientes tratamientos distribuidos en un diseño completamente al azar con arreglo bifactorial, de 6 tratamientos y cuatro repeticiones. El método de trasplante empleado fue en hileras con un determinado marco de plantación de (20 cm x 30 cm, 20 cm x 20 cm y 20 cm x 10 cm), para ambas variedades. Así también se planteó las siguientes variables de respuesta: porcentaje de germinación, días a la emergencia, altura de planta, número de hoja, longitud de hoja, ancho de la hoja, días a la cosecha, rendimiento de biomasa y análisis económico. De los resultados alcanzados, en las variables agronómicas evaluadas, no mostraron significancia estadística en la variable ancho de hoja; con relación al peso de la variable rendimiento de biomasa tenemos que el T6 de la variedad Viroflay a un marco de plantación de 20 cm x 10 cm, presento un peso promedio de 675, 45 g. En cuanto al análisis económico del experimento tenemos que T6 de la variedad Viroflay a un marco de plantación de 20 cm x 10 cm es uno de los tratamientos con mayor valor de beneficio/ costo igual a Bs. 1,10.-, del cual podemos establecer que genera beneficios y por tanto por cada boliviano invertido existe un mínimo de ganancia.

"Climate is the average state of weather events observed on earth over many years. Changes occur in climate over time with natural or antropological (human) effects. Shifts in climate due to natural factors are defined as climate variability. Natural causes of climate change include solar eruptions, changes in the earth’s orbital parameters, and volcanism. The use of carbon- containing fossil fuels, unplanned urbanization, and the steady disappearance of forested areas that act as greenhouse gas sinks are the causes of human-induced changes in the climate. The term “climate change” refers to both driven on by human activity and the change in the climate carried on by natural factors. During the latter half of the 19th century, researches on the impact of greenhouse gases on global warming provided the basis for the first studies on climate change. The studies gained momentum following the establishment of the Intergovernmental Panel on Climate Change (IPCC) in 1988, which was initiated by the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP). With the 1997 approval of the Kyoto Protocol and the 2015 adoption of the Paris Agreement, an international struggle against climate change has been planned. Nationally, the First Climate Council in 2022 was held in line in an effort to fight climate change and promoting green development. Institutionally, the Climate Change and Changeability Unit was established in 1991 under the Turkish State Meteorological Service (TSMS) against climate change. In 1992, the Atmospheric Conservation and Climate Change report was published. The importance of this report is that it is the first report on climate change published in Türkiye. In 2008 for the first time, a comprehensive projection analysis was conducted as a TUBITAK project with the cooperation of TSMS - ITU. In 2012, for the first time as a public institution, the TSMS runned large-scale climate projections in Türkiye. Within the scope of projection studies, 3 global climate models outputs were simulated with a regional climate model using 2 different scenarios (RCP4.5 and RCP8.5) at 20 km horizontal resolution with the dynamic downscaling method. The climate data, which form the basis of the climate projection data operated, are the data contributed to the global climate models from 2054 observation systems of TSMS located throughout Türkiye."

"There are changes in the frequency, intensity, geographical distribution and duration of extreme weather and climate events, with the impact of global climate change. The increase in extreme weather and climate events will continue according to the Assessment Reports of the Intergovernmental Panel on Climate Change (IPCC). Accordingly, it is expected that there will be an increase in disasters caused by natural hazards. Although earthquakes are the most widely known nature-based disasters, disasters that occur due to severe and extreme meteorological events constitute a large part of nature-based disasters. As in the whole world, meteorological disasters have been occurring quite frequently in our country, which has large geographic and different climatic regions, and have resulted in serious losses of life and property during the recent periods. There has been a considerable increase in the number and the strength of meteorological disasters, especially after the 2000s. The transformation of severe and extreme meteorological events into disasters is a natural consequence of the failure of human systems to be prepared and take precautions against extreme weather and climate risks, as well as local or regional geographical factors such as incorrect settlement and incorrect land use practices. Experienced meteorological disasters and their consequences reveal the importance of considering forecasts and early warnings, being ready to overcome severe and extreme weather events before they turn into disasters, or even if they do, for the least possible damage, taking the right precautions in a timely manner. The prediction of atmospheric events has brought many conveniences because of the widespread use of High-Performance Computing Systems. With the prepared numerical weather prediction models, changes and atmospheric events that may occur in the atmosphere from minute to hour, from day to week can be predicted. It is also very important that the produced early warning products can be understandable by the public, as well as obtaining forecasts to reduce disaster hazards. Turkish State Meteorological Service (TSMS), which is a forecasting and early warning institution, presents the meteorological forecasts and early warnings it has prepared to the information of all public and relevant public institutions/organizations and continues its activities as the first part of the disaster risk reduction chain."

"Today, groundwater is the source of about a third of global water withdrawals and provides drinking water to a large proportion of the world’s population. Groundwater resources are considered a more reliable source than surface water resources, as they are more protected against atmospheric conditions. Climate change creates uncertainties regarding the supply and management of water resources. While the two basic elements of the climate the temperature and precipitation trend affect the regional droughts, the frequency, and severity of floods, the amount of surface runoff, and the recharge and discharge mechanisms of groundwater are also affected by these changes. Türkiye is one of the most vulnerable countries to the effects of climate change. The country’s average air temperature tends to increase continuously since the 1990s, and precipitation regimes are changing. Climate factors, population growth, increase in agricultural and industrial activities, and unlicensed wells create changes in groundwater supply and demand. The use of groundwater for agricultural purposes in Türkiye is increasing every year and today this rate is 67%. When the groundwater levels are examined from past to present, these resources are faced with the problem of decrease in most regions and even depletion in some regions. In particular, in the Marmara, Aegean, Central Anatolia, and Southeastern Anatolia regions, the groundwater levels have decreased about 100 meters. The continuation of this trend may cause irreversible problems for aquifers, which are an important source for domestic, industrial, and agricultural irrigation and provide the continuity of the ecosystem by feeding the streams in dry periods. In addition, projections for the future reveal that water stress will increase in many parts of Türkiye due to climate change and increasing water demands. For this reason, it is of great importance for the sustainable use of water resources to evaluate the current situation of groundwater and to develop water management policies by predicting the effects of climate change. This article provides a general framework on climate change and the current state of Türkiye’s groundwater."

"Earth’s climate is changing much faster than it is used to be. Climate change has adversely affected all systems in which human beings are at the center. Since Türkiye is located in Mediterranean Basin, which will be greatly affected by climate change; all sectors including water resources, agriculture, hydrometeorological disasters and forests are under threat. Average temperature increases across Türkiye are expected to reach 5.9°C by the end of the century due to climate change. Although precipitation decreases vary in each region, it is expected to become more prominent by 2050s. Furthermore, reductions in snow cover are expected. As a result, it is estimated that there will be a serious water deficit in the Euphrates- Tigris and Konya River Basins."
