The problems of biodiversity reduction and degradation of river ecosystems in the Russian Far East require urgent solutions. This is especially important for areas of intensive development and urbanized territories that are located in the areas of the strongest anthropogenic impact. In order to understand the processes taking place in such ecosystems, an adequate assessment of their ecological state is necessary, based on reliable methods of integrated assessment adapted to regional conditions. To this end, a long-term scientifi c project «Development of methods for a comprehensive assessment of the ecological state of East Russian streams and rivers under anthropogenic infl uence» was initiated. The Muravyov- Amursky Peninsula, on which the Vladivostok urban agglomeration is located, was chosen as a model territory.
ESTIMATION OF WATER QUALITY ACCORDING TO THE EPT INDEX IN THE KAMCHATKA PENINSULA RIVERS IN AUTUMN, TAKING INTO ACCOUNT REGIONAL FEATURES OF THE FAUNA

The paper presents the results of the water quality assessing in the surveyed areas of the foothill Kamchatka Peninsula Rivers in the autumn of 2023. The EPT index of indicator groups of mayfl ies (Ephemeroptera), stonefl ies (Plecoptera), and caddisfl ies (Trichoptera) in the streams of the Bolshaya, Kamchatka, and Avacha River Basins varied within 8–16, which corresponds to the standard of good-fair or fair water quality. However, given that the fauna of these indicator orders of aquatic insects in the Kamchatka Rivers is slightly more than 20 % of that in the south of the Far East; these regional features are also refl ected in the indices when assessing water quality, in particular, in the number of EPT species. And if the water quality is considered good if there are 24–31 species in the rivers of the south of the Far East, then for the watercourses of Kamchatka such water quality, which we assessed with an index of 10 to 16, is quite justifi ed. It is also necessary to take into account seasonal changes in the fauna, since the samples were taken in September, when most of the indicator taxa left the streams, and a number of species of the new generation had not yet hatched. Our results can be confi rmed by studies conducted earlier in the areas of existing economic facilities on the Kamchatka Peninsula, which showed that the EPT index in the background river sections varied from 10 (Agi R.) to 13 (Tolmacheva R.), which is comparable with our results.
U.S.-China Cyber Warfare in the 21st Century: Implications for International Security
Authors: Khan Sarmad Ali , Abbasi Saira Nawaz
Published: June 2023

The power competition between the major powers of the world has always been dependent on the strategic security landscape. Over the years, military operations and warfare have evolved with the development of new weapons, equipment, and technologies. During the 20th century, the world witnessed a transformation from conventional strategic competition to unconventional strategic competition with the advent of nuclear weapons. The genesis of the 21st century marked another revolution in military affairs when electronic warfare was modernized and cyber warfare came into the spotlight. In the current century, new poles of powers have emerged whereby Beijing and Washington started competing at all levels and in all domains. Shortly after the incorporation of digital, electronic, and cyber equipment and techniques by militaries around the world, cyberspace became militarized and emerged as the fifth battlefield. The U.S. armed forces and the Chinese PLA both rely heavily on cyberspace when it comes to their communication, operations, and planning. Cyber campaigns launched by Washington and Beijing on various targets accounted for a cyber arms race and continuous cyberspace strategic competition between the two countries.
Western Perception and Media Coverage of Türkiye’s Elections
Authors: Giannotta Valeria
Published: June 2023

Media coverage of the recent elections in Türkiye, especially in the first round, has proven the profound distortion of image and misperception in some Western circles. Although a biased reading of the events, which pivots mainly on ideological connotations, aimed at influencing the outcome of the vote, it resulted in mere wishful thinking. The role of the media in influencing communication through the framing of the agenda has empirical evidence; however, in the case of Türkiye, a cognitive gap has opened up between expectations and reality, which lies on a non-objective and sometimes emotional interpretation of the facts. The electoral results, by denying once again any superficial prediction and manipulation attempt, must be read as a lesson on how to look at Türkiye, its government, and its people and therefore generate more accurate and genuine information.
Turks Vote in Favor of Continuing the Erdoğan Era
Authors: Bezci Bünyamin
Published: June 2023

The political landscape in Türkiye has changed since the 2010s, setting the stage for the elections in 2023. The Nation Alliance and the People's Alliance were formed as a result of electoral alliances in the center. After the 2019 municipal elections, the Nation Alliance felt more confident, whilst the People's Alliance encountered difficulties because of socioeconomic problems and earthquakes. The Nation Alliance and the HDP collaborated covertly during the campaign in order to win the PKK's backing. They had internal conflicts and placed more emphasis on virtual platforms than on actual issues. President Erdoğan's ruling party demonstrated its capacity to keep its promises by taking action. They were able to gain the legislative majority and re-elect President Erdoğan thanks to their composure, quick reactions, technical foresight, and remoteness from terrorists. The CHP, İP, HDP, and YSP all saw losses as a result of the elections, while fringe groups within the Nation Alliance gained the most. Internal elections are to be held by CHP and İP to quell disagreements about the party's leaders. In this sense, short-term changes remain unlikely in any of the movements that pledged “change.”
A Comparative Analysis of Turkish Foreign Policy on the Azerbaijan-Armenia Conflicts (1988-2020)
Authors: Öztığ Laçin İdil
Published: June 2023

With the collapse of the Soviet Union, the relative stability that prevailed in the Caucasus region during the Cold War period dissolved into instability and conflicts. This article is based on a comparative analysis of Turkish foreign policy in the context of the Azerbaijan-Armenia conflicts. During the First Nagorno-Karabakh War, Türkiye gave political and military support to Azerbaijan, but this support was not sufficient to change the course of the conflict. Türkiye showed an ardent interest in playing a mediator role. However, its mediator role was limited due to domestic and external circumstances. During the Nakhchivan conflict, Turkish policymakers brought up the possibility of interfering militarily to end the conflict in line with Türkiye’s legal commitments. However, Türkiye’s pro-Azerbaijani position took the form of discursive reactions and border militarization. When the Second Nagorno-Karabakh War erupted in 2020, Türkiye played a much more assertive role to the point of actively contributing to tilting the balance in favor of Azerbaijan. This article compares Türkiye’s position on the Azerbajani-Armenian conflicts and discusses its impacts and implications in the context of the regional dynamics.

Published: June 2023

Vitamin B1 (thiamine) plays an important role in various metabolic processes and is one of the main factors in the body's health. Thiamine excess and deficiency in the body might cause a variety of diseases such as shortness of breath, beriberi, and heart failure, hence thiamine levels must be detected as a reference for intake. The present research detected thiamine using the amperometric biosensor method and the yeast Saccharomyces cerevisiae as a bioreceptor. Dissolved oxygen (DO) level measurement parameters are considered based on yeast cell metabolism. Thiamine was treated with various concentrations of 15 mM, 30 mM, 45 mM, 60 mM, and 75 mM. The measurement results are in the voltage range of 1912–1964 mV, where the addition of thiamine causes an increase in the reproducibility and growth rate of yeast cells. The ideal characteristics of the biosensor based on the parameters of sensitivity, linearity, and stability was also carried out, which resulted in successive biosensor measurements of 0.925 mV/mM, a correlation coefficient of r = 0.9868, and a decrease in the voltage response of the biosensor up to 4.97% from its initial activity. The measured data were grouped and classified using principal component analysis (PCA), which resulted in a total accumulated data variance percentage of 84.5% and an eigenvalue > 1 for both PCs. It is intended that the findings of this research can be utilized as a reference for controlling vitamin consumption levels that have an impact on health.

Authors: Talavera Andújar Begoña , Mary Arnaud , Cheng Tiejun , Zaslavsky Leonid , Bolton Evan , Heneka Michael , Schymanski Emma
Published: June 2023

Alzheimer’s Disease (AD) is a complex and multifactorial neurodegenerative disease. The current diagnosis relies on non-specific biomarkers (Aβ1-42, t-Tau, and p-Tau) measured in cerebrospinal fluid (CSF), which do not provide sufficient insights into disease progression. Studying the exposome could reveal new disease-specific biomarkers for more accurate diagnosis. In this pilot study, exposomics was performed on the CSF of three groups; AD, Mild Cognitive Impairment (MCI) due to AD, and a non-demented control group (ND), using non-target high resolution mass spectrometry (NT-HRMS) coupled with liquid chromatography (LC). An open-source cheminformatics pipeline was developed using MS-DIAL and patRoon with PubChemLite for Exposomics, plus CSF- and AD-specific suspect lists. Fifteen statistically significant chemicals (nine Level l, six Level 2a) from diverse classes (amino acids, gut metabolites, sugars, environmental chemicals) were identified. Most of the relevant chemicals (thirteen out of fifteen) were detected using the Hydrophilic Interaction LC (HILIC) method. Environmental and lifestyle factors may explain some chemical differences found across groups, such as the higher levels of indole-3-acetic acid found in the AD and MCI compared to the ND group. This work provides a strong methodological basis and several promising hypotheses to upscale these efforts on larger AD cohort numbers in future studies.

Published: June 2023

The discorhabdin natural products are a large subset of pyrroloiminoquinone alkaloids with a myriad of biological activities. Despite garnering much synthetic attention, few members have thus far been completed, with none featuring a bridging carbon–nitrogen bond that is found in numerous discorhabdins, including discorhabdin V. Here we report the first total synthesis and full stereochemical assignment of (+)-discorhabdin V in 13 linear steps. To access the pyrroloiminoquinone we developed a convergent N-alkylation/oxidative aminocyclization/bromination cascade that joins two key components, which are both made on multigram scale. An intramolecular Heck reaction then forms the quaternary carbon center in an intermediate containing the carbon–nitrogen bridge, and a reductive N,O-acetal cyclization sequence introduces the final piperidine ring. Furthermore, we have established the relative stereochemistry of (+)-discorhabdin V through experimental NOESY data and DP4 NMR probability calculations. The absolute configuration of the natural product has also been determined via circular dichroism and the use of an amino acid-derived chiral starting material. Our work represents the first report of a total synthesis of a nitrogen-bridged discorhabdin and paves the way for future biological evaluation of such compounds.
Capturing and Assessing the Sustainability of Frugal Innovations
Authors:   International Institute of Social Studies - ISS, Pineda-Escobar Maria Alejandra
Published: June 2023

It has been proposed that frugal innovation can contribute to the attainment of sustainability in resource-scarce contexts. However, not all frugal innovations are necessarily sustainable by definition, and little is currently known about the frugality-sustainability link. This short paper is part of a research project that reveals the scarcity of evidence-based claims on the sustainability potentials and pitfalls of frugal innovation and emphasizes the need to count with better ways in which these can be captured and assessed.
A Framework for Pairing Circular Economy and IoT: Creating value by developing business models for the interplay of circular economy with IoT
Authors:   École des Ponts Business School, Adamidis Chrysostomos , Craven Annette , Dober Dariusz ,   BlueSoft Sp. z o.o, Alexandris George
Published: June 2023

Economic growth from increasingly scarce resources is becoming a key global challenge. The circular economy (CE) provides a promising alternative to the current economic system. It is conceived as a continuous positive development cycle, reforming the current economic model of “take-make-dispose” by preserving and enhancing natural capital, optimizing resource yields, and minimizing system risks by efficiently managing finite stocks and renewable flows (Morlet et al., 2016). The internet of things (IoT) connects the digital and physical worlds by collecting, measuring, and analyzing data to predict and automate business processes. It enables the implementation of circular economy principles, including resource efficiency, asset lifecycle extension, and maximizing asset retained value and recovery. This paper explores the business model for the interplay of circular economy with IoT. Specifically, pairing circular principles and integrating IoT architecture to develop Poland’s intelligent Demand Side Response (DSR) electricity system. The model proposes the use of intelligent technology assets to regulate energy demand according to energy supply and thereby reducing the costs for the consumers and improving asset utilization for the energy distributors while at the same time reducing overall energy consumption and carbon emissions and increasing the potential for the use of renewable energy sources. The DSR model is developed by focusing on the external digital business ecosystem. Further research is required to identify the intra-organizational drivers and challenges organizations face in adopting digitally enabled circular business models.

Authors:   Maastricht University, Nyffenegger Roger , Grösser Stefan ,   Bern University of Applied Science, Bocken Nancy
Published: June 2023

This research paper analyzes the value proposition, creation, and capture of circular solar photovoltaic (PV) business models in Switzerland, with a focus on product-service system (PSS)-related PV business models. The paper identifies three areas of circular solar PV business models within the midstream value chain: application-related, position-related, and interaction-related. The paper also discusses the benefits and drawbacks of PSS business models in demand-side focus groups and presents possible solutions on which the supply side can focus. The research aims to contribute to the adoption of PSS-related solar PV business models by business-to-business (B2B) and business-to-government (B2G) customers.
Business as usual? The behavioural consistency of short-term rental platform hosts despite the challenges of the pandemic
Authors:   University of Siena, Sanna Venere Stefania
Published: June 2023

The Covid-19 pandemic that started in March 2020 had a significant impact on the freedom of movement of the global population, impacting the activity of short-term rental platforms (STRs). According to several studies (Romano 2021, Dagkouli-Kyriakoglou et al 2022), during the peak of the pandemic the number of listings dropped in many major markets. In Europe, Spain lost 59% of booking days in 2020, Italy 58%, France 33%, and Germany 39% (Dagkouli-Kyriakoglou et al 2022, p. 5). Even more pronounced was the decrease in the occupancy rate of urban listings (measured in terms of reviews) recorded at the main tourist destinations in Italy compared to 2019: Rome was down 70.07%, Milan 77.71%, Florence 77.55%, and Naples 63.92% (Romano 2021, p. 5). Nevertheless, while the impact of the pandemic on the geography of STR listings is evident, empirical evidence on the business strategies adopted by hosts to survive the crisis is scarce. The aim of this contribution is to present and discuss a detailed empirical analysis based on STR host data for the period November 2021¬April 2022. To reveal any changes induced by the pandemic in five Italian cities – Rome, Florence, Venice, Naples, and Turin – information from 411 respondents who participated in a direct online survey is presented. The author investigates in particular (i) actions taken during the pandemic (e.g., cancelation of listings, changes in business/organizational model, etc.); (ii) future “post pandemic” strategies (e.g., rent accommodation differently, sell the property, etc.) and (iii) the impact on hosts’ income.
Circular Business Models as Instruments of Corporate Power
Authors:   Cardiff University, Wells Peter , Skeete J-P
Published: June 2023

The creation of circular business models to deliver the circular economy has been widely accepted as offering significant sustainability benefits. A related expectation is that in creating circular business models, focal companies will necessarily need to encompass multiple stakeholder partnerships to access the resources and skills which they lack. In combination, these two expectations result in a neglect of the potential for focal companies to increase their power and control over the entire product lifecycle for which the outcomes are at best uncertain. This paper proposes a research agenda on corporate power in the circular economy, with a focus on the exclusive control over natural capital that circularity may enable in the form of circular vertical integration. Competitive forces are argued to be fundamental to the corporate drive to control natural capital. The paper is empirically grounded in a case study of VW Group in the automotive industry and its transition to battery electric vehicles. It is concluded that previous research into business model innovation for the circular economy has often mistakenly assumed benign stewardship in which corporate hegemony is mitigated by stakeholder engagement, such that a more critical perspective is needed.
A FRAMEWORK FOR DECODING PHYSIOLOGICAL AND NEURAL SIGNAL USING LONG SHORT-TERM MEMORY (LSTM)
Authors:   Department of Computer Science  Federal University Otuoke Yenegoa, Bayelsa State, Nigeria, Mary Obasi, Emmanuela Chinonye
Published: June 2023

Machine learning for deciphering physiological and neural signals holds great promise for use in creating brain-computer interfaces. (BCIs). Brain-computer interfaces (BCIs) are tools for using mental activity to operate mechanical or electronic equipment. To convert these signals into actionable instructions for the external device, machine learning algorithms are employed. Brain-computer interfaces (BCIs) have shown considerable promise in enhancing the lives of people who are unable to use their limbs normally due to injury or illness. This paper presents an LSTM model for the decoding of physiological and neural signals. In this paper, an electroencephalography brain signal data was used. The dataset was pre-processed so as to remove noise from the data. The pre-processed data was used in training the LSTM model. The LSTM model was trained on fourteen (14) steps. The result of the LSTM model showed an accuracy of 85% at the first step and a validation (testing) accuracy of 90%. For the fourteenth step, the model achieved an accuracy result of 98% for training and 94% for validation (testing). We also evaluated the performance of the model using a classification report and confusion matrix. The result of the classification report shows an accuracy of 95%. This means that the performance of the model on the test data is efficient. The confusion matrix was used in how well the model classified the electroencephalography signal The result of the confusion matrix shows that the model predicted the result correctly to be neutral 151 out of 153, positive to be 127 out of 142, and negative to be 128 out of 132. The result shows that the level of false positive and negative values is minimal.

Exploring the Nature and Influence of Intermediate-Depth Seismicity Beneath the Taupō Volcanic Zone
Authors:   , Mark Olivia
Published: June 2023

The central Taupō Volcanic Zone (TVZ) hosts the most productive rhyolitic volcanic system in the world. A link has been proposed between the composition of deep subduction fluids and the extreme productivity of the caldera volcanoes in the central TVZ (Taupō and Ōkataina), largely based on geochemical studies. It is hypothesised that fluids freed from dehydration reactions in the subducting slab facilitate intermediate-depth earthquakes through dehydration-related embrittlement. These fluids can migrate into the mantle wedge and contribute to partial melting of the primitive magma source, which influences the flux of magmas to the central TVZ calderas. In this thesis we aim to investigate the potential link between these earthquakes and the subduction fluid signature that is present in the central TVZ caldera volcanoes. Well-constrained earthquake locations and their faulting parameters can help us better understand this relationship. The new earthquake catalogue produced in this thesis contains 397 earthquakes between depths of 50–305 km. These were located with 40,266 manual P- and S-picks, a 3D velocity model, and relocated using relative relocation techniques. These locations are further refined by observations of converted and reflected seismic phases, unique to earthquakes nucleating in various regions of the subducting slab.

We observe a double seismic zone (DSZ) beneath the central TVZ. This occurs in one section of the slab, at depths of 145–190 km and the seismic planes are separated by an aseismic plane <8 km wide. The stress state of the subducting slab, as determined by 47 focal mechanisms, has an upper seismic plane in down-dip extension and a lower seismic plane in down-dip compression. We also identify earthquakes occurring in the mantle wedge whose computed focal mechanisms indicate that they typically occur on near vertical faults.

The pattern of intermediate-depth seismicity we observe is consistent with earthquakes being facilitated by dehydration reactions in the oceanic slab crust and mantle. The abundant fluids released from these reactions have distinct geochemical signatures, that have been previously identified in the eruptive products of the caldera volcanoes in the central TVZ. We therefore provide evidence of a link between intermediate-depth seismicity and magmatism in the central TVZ. Additionally, the uniqueness of the Hikurangi slab, which has an unusually high fracture permeability, its oblique subduction beneath the North Island and its thermo-mechanic structure, is likely a significant contributor to the anomalous rhyolitic volcanism observed in the central TVZ.

THE INFLUENCE OF THE 6-PHASE LEARNING CYCLE - THINK PAIR SHARE LEARNING MODEL ON LEARNING OUTCOMES AND STUDENT RETENTION ON CHEMICAL EQUILIBRIUM MATERIALS
Authors: Hidayati Ririn Eva , Maharani Dina Kartika
Published: June 2023

This study aims to decide the influence of the Learning Cycle 6 Phase - Think Pair Share learning model on knowledge results and student retention on chemical equilibrium material. The research design was a quasi-experimental research design without a pretest (posttest-only control group design). All students of class XI MAN 1 Kota Malang were used as the population in this study. The sample selection was carried out using the cluster random sampling technique and 2 research groups were acquired. Class XI MIPA 6 was selected as the experimental class using the Learning Cycle 6 Phase - Think Pair Share learning model while class XI MIPA 5 was selected as the control class using the Learning Cycle 6 Phase. The number of students in class XI MIPA 5 was 36 students, while the amount of students in class XI MIPA 6 was 34 students. The measurement instrument used is a test. The test was carried out after being given treatment to measure students' skills to recognize the concept of chemical equilibrium. In addition, there is a retention test that is held 1 week and 1 month after students study chemical equilibrium material without prior notification. Test the hypothesis to determine whether there was a substantial difference in education outcomes and retention between schoolchildren taught by the 6-Phase Learning Cycle - Think Pair Share learning model and students taught with the 6-Phase Learning Cycle model in chemical equilibrium material with the Independent Sample T-Test. The data analysis technique used consisted of preliminary analysis consisting of a normality test and homogeneity test and analysis of results consisting of hypothesis testing. The outcomes of the Independent Sample T Test showed a likelihood worth of fewer than 0.05 which indicated that there was a substantial difference between the knowledge outcomes of the experimental group and the control group. The probability values of retention tests I and II are also smaller than 0.05. This shows that there is a substantial difference amongst the retention test of the experimental group and the control group on retention tests I and II. The outcomes of this research show that the midpoint knowledge outcomes in the experimental group are higher than the midpoint knowledge outcomes in the control group, namely 77 in the experimental class and 71 in the control class. This proves that the Learning Cycle 6 Phase - Think Pair Share learning model has an effect on student learning outcomes of MAN 1 Kota Malang on chemical equilibrium material. This model also affects student retention.

Los pódcast se han planteado como un híbrido entre charla magistral y entrevista, siendo mayor una y otra dependiendo el tema a abordar. Sin embargo, la presente obra trae por escrito dichas reflexiones en un formato reducido y para facilitar un mayor acceso a dichos documentos, en este caso en soporte escrito. Los Objetivos de Desarrollo Sostenible (los ODS) buscan hacer de nuestro planeta un lugar mejor en el que vivir y donde se ponga fin a la pobreza, se proteja el medioambiente de nuestro planeta y se garantice que todas las personas gozamos de paz, libertad e igualdad. Con ese fin, diferentes aspectos del derecho están adaptándose para conseguir dichas metas que abarcan prácticamente todas las esferas y ámbitos de nuestra rutina. Sírvase las reflexiones y visiones de los/as expertos/as participantes como una aproximación a esos cambios que se han producido o están produciéndose, e incluso alguna crítica a cómo debería modifcarse el Derecho para cumplir los ODS. Por último, debo agradecer la intervención de todos ellos/ellas, su apreciado tiempo en la elaboración del presente Proyecto. Y debo hacer extensible el agradecimiento a Eva Entrena Fernández, especialista de medios audiovisuales del Laboratorio de Medios Audiovisuales de la Facultad (SEMETA) de Filosofía y Letras de la Universidad de Zaragoza, por ayudar en la elaboración de los pódcast y su buen hacer.

Trybunał Konstytucyjny pomiędzy dwoma światopoglądami – Kelsenowska interpretacja orzecznictwa TK w kwestii prymatu Konstytucji
Authors: Włoch Wojciech
Published: June 2023

Celem artykułu jest próba interpretacji znaczenia zasady prymatu konstytucji w orzecznictwie Trybunału Konstytucyjnego. Orzecznictwo TK do roku 2021 można zinterpretować jako wyraz monizmu monadologicznego: państwa-monady wspólnie współkonstytuują meta-monadyczny system norm i instytucji, przy czym żadna z monad nie traci statusu suwerenności. W zakresie państwa-monady może obowiązywać zasada prymatu konstytucji. Natomiast od 2021 r. zaczyna się przejawiać monizm solipsystyczny: państwo-Ego jest źródłem i absolutną podstawą systemu norm obowiązujących na jego terytorium. Z tego punktu widzenia ponadnarodowe instytucje mogą się jawić jako zagrożenie dla suwerenności państwa-Ego. Obydwa światopoglądy można zinterpretować jako reakcję na proces powstawania konstytucjonalizmu 3.0. Monizm monadologiczny chciałby zachować i dostosować pojęcie suwerenności w nowym kontekście, natomiast monizm solipsystyczny zatrzymać sam proces zmian i zachować suwerenność niewzruszoną.
