This paper proposes a controller to track the maximum power point (MPP) of a photovoltaic (PV) system using a fractional-order proportional integral derivative (FOPID) controller. The employed MPPT is operated based on a dp/dv feedback approach. The designed FOPID-MPPT method includes a differentiator of order (μ) and integrator of order (λ), meaning it is an extension of the conventional PID controller. FOPID has more flexibility and achieves dynamical tuning, which leads to an efficient control system. The contribution of our paper lies is optimizing FOPID-MPPT parameters using Aquila optimizer (AO). The obtained results with the proposed AO-based FOPID-MPPT are contrasted with those acquired with moth flame optimizer (MFO). The performance of our FOPID-MPPT controller with the conventional technique perturb and observe (P&O) and the classical PID controller is analyzed. In addition, a robustness test is used to assess the performance of the FOPID-MPPT controller under load variations, providing valuable insights into its practical applicability and robustness. The simulation results clearly prove the superiority and high performance of the proposed control system to track the MPP of PV systems.

Natural metabolites from beneficial fungi were recognized for their potential to inhibit multidrug-resistant human and plant fungal pathogens. The present study describes the isolation, metabolite profiling, antibacterial, and antifungal, antioxidant, and anticancer activities of soil fungi. Among the 17 isolates, the AK-7 isolate was selected based on the primary screening. Further, the identification of isolate AK-7 was performed by 18S rRNA sequencing and identified as Penicillium limosum (with 99.90% similarity). Additionally, the ethyl acetate extract of the Penicillium limosum strain AK-7 (AK-7 extract) was characterized by Fourier Transform Infrared Spectroscopy (FTIR) and a Gas Chromatography-Mass Spectroscopy (GC-MS) analysis, and the results showed different functional groups and bioactive metabolites. Consequently, a secondary screening of antibacterial activity by the agar well diffusion method showed significant antibacterial activity against Gram-negative and Gram-positive bacterial pathogens. The AK-7 extract exhibited notable antifungal activity by a food poisoning method and showed maximum inhibition of 77.84 ± 1.62%, 56.42 ± 1.27%, and 37.96 ± 1.84% against Cercospora canescens, Fusarium sambucinum and Sclerotium rolfsii phytopathogens. Consequently, the AK-7 extract showed significant antioxidant activity against DPPH and ABTS•+ free radicals with IC50 values of 59.084 μg/mL and 73.36 μg/mL. Further, the anticancer activity of the AK-7 extract against the human ovarian teratocarcinoma (PA-1) cell line was tested by MTT and Annexin V flow cytometry. The results showed a dose-dependent reduction in cell viability and exhibited apoptosis with an IC50 value of 82.04 μg/mL. The study highlights the potential of the Penicillium limosum strain AK-7 as a source of active metabolites and natural antibacterial, antifungal, antioxidant, and anticancer agent, and it could be an excellent alternative for pharmaceutical and agricultural sectors.

Published: October 2023

Recent advances in phenotyping techniques have substantially improved the ability to mitigate type-II errors typically associated with high variance in phenotyping data sets. In particular, the implementation of automated techniques such as the High-Volume Instrument (HVI) and the Advanced Fiber Information System (AFIS) have significantly enhanced the reproducibility and standardization of various fiber quality measurements in cotton. However, micronaire is not a direct measure of either maturity or fineness, lending to limitations. AFIS only provides a calculated form of fiber diameter, not a direct measure, justifying the need for a visual-based reference method. Obtaining direct measurements of individual fibers through cross-sectional analysis and electron microscopy is a widely accepted standard but is time-consuming and requires the use of hazardous chemicals and specialized equipment. In this study, we present a simplified fiber histology and image acquisition technique that is both rapid and reproducible. We also introduce an automated image analysis program that utilizes machine learning to differentiate good fibers from bad and to subsequently collect critical phenotypic measurements. These methods have the potential to improve the efficiency of cotton fiber phenotyping, allowing for greater precision in unravelling the genetic architecture of critical traits such as fiber diameter, shape, areas of the secondary cell wall/lumen, and others, ultimately leading to larger genetic gains in fiber quality and improvements in cotton.
Epistemic Challenges in Neurophenomenology: Exploring the Reliability of Knowledge and Its Ontological Implications
Authors: Shutaleva Anna
Published: October 2023

This article investigates the challenges posed by the reliability of knowledge in neurophenomenology and its connection to reality. Neurophenomenological research seeks to understand the intricate relationship between human consciousness, cognition, and the underlying neural processes. However, the subjective nature of conscious experiences presents unique epistemic challenges in determining the reliability of the knowledge generated in this research. Personal factors such as beliefs, emotions, and cultural backgrounds influence subjective experiences, which vary from individual to individual. On the other hand, scientific knowledge aims to uncover universal truths based on empirical observations and objective principles. Reconciling the subjective and objective realms presents a significant challenge in determining the reliability of knowledge generated through neurophenomenological research. This article aims to examine the inherent limitations and challenges of neurophenomenological research to shed light on the complexities involved in understanding the nature of knowledge itself. This article highlights that the ontological implications of the reliability of knowledge in neurophenomenology arise from the question of how subjective experiences relate to objective reality. Understanding the neural correlates and mechanisms behind subjective experiences can provide insight into the underlying ontological nature of consciousness.
Multi-Event Location Denoising Scheme for φ-OTDR Based on FFDNet Network
Authors: Yang Xiyu , Li Shuai , Xu Yanping , Liu Zhaojun , Qin Zengguang
Published: October 2023

In order to improve the signal-to-noise ratio (SNR) of vibration sensing in the phase-sensitive optical time-domain reflectometer (φ-OTDR) system, a fiber sensing signal processing method based on the FFDNet convolutional neural network is proposed in this paper. In the network, the concept of residual learning is introduced, which involves constructing a residual mapping and utilizing multi-layer convolutional neural networks to learn the noise distribution present in the original image. The denoised result can be obtained by subtracting the learned noise from the original image. We have built a φ-OTDR system based on coherent detection, using three PZTs as simulated vibration sources and a series of experiments at 200 Hz, with each experiment simulating a single vibration event or multiple vibration events by setting different intensities. The experimental results demonstrate that the FFDNet based fiber optic sensing signal processing method enhances the SNR to 37.84 dB, 37.11 dB, and 37.31 dB, respectively, while preserving vibration signal details more effectively than wavelet denoising and Gaussian filtering techniques. The trained FFDNet model has great potential for improving the performance of the φ-OTDR system and has some practical application value.
Barry Turner: The Under-Acknowledged Safety Pioneer
Authors: Bills Kym , Costello Leesa , Cattani Marcus
Published: October 2023

Barry Turner’s 1978 Man-made Disasters and Charles Perrow’s 1984 Normal Accidents were seminal books but a detailed comparison has yet to be undertaken. Doing so is important to establish content and priority of key ideas underpinning contemporary safety science. Turner’s research found socio-technical and systemic patterns that meant that major organisational disasters could be foreseen and were preventable. Perrow’s macro-structuralist industry focus was on technologically deterministic but unpredictable and unpreventable “system” accidents, particularly rare catastrophes. Andrew Hopkins and Nick Pidgeon respectively suggested that some prominent writers who wrote after Turner may not have been aware of, or did not properly acknowledge, Turner’s work. Using a methodology involving systematic reading and historical, biographical and thematic theory analysis, a detailed review of Turner’s and Perrow’s backgrounds and publications sheds new light on Turner’s priority and accomplishment, highlighting substantial similarities as well as clear differences. Normal Accidents did not cite Turner in 1984 or when republished with major additions in 1999. Turner became better known after a 1997 second edition of Man-made Disasters but under-acknowledgment issues by Perrow and others continued. Ethical citation and potential reasons for under-acknowledgment are discussed together with lessons applicable more broadly. It is concluded that Turner’s foundational importance for safety science should be better recognised.
Color Perspectives in Aquatic Explorations: Unveiling Innate Color Preferences and Psychoactive Responses in Freshwater Crayfish

Published: October 2023

Color preference assay is a test for an animal’s innate and adaptive response to differentiate colors and can be used as an endpoint for psychoactive activity evaluation. Several color preference test methods in aquatic animals that can be used to perform behavioral screening have been established. However, the color preference test conditions have yet to be extensively studied and standardized in aquatic invertebrates. This study aimed to replicate and optimize the previously published method to evaluate the potential color preference in freshwater crayfish based on four different approaches: species, life stages, sex, and pharmaceutical exposure. Using the optimized setup, two crayfish species display color preferences to some specific colors. P. clarkii displays more dominant color preference behavior than C. quadricarinatus in terms of color preference ranking and index. P. clarkii prefers the red color compared to other colors (red > green > blue > yellow), while C. quadricarinatus dislikes yellow compared to other colors (blue = green = red > yellow). Since P. clarkii has a more obvious color index ranking and several advantages compared to C. quadricarinatus, we conducted further tests using P. clarkii as an animal model. In the juvenile and adult stages of P. clarkii, they prefer red and avoid yellow. However, the juvenile one did not display a strong color preference like the adult one. Different sex of crayfish displayed no significant differences in their color preference responses. In addition, we also evaluated the potential effect of the antidepressant sertraline on color preference in P. clarkii and found that waterborne antidepressant exposure can significantly alter their color preference. This fundamental information collected from this study supports the crayfish color preference test as a good behavioral test to address environmental pollution.

Authors: Lessi Leandro
Published: October 2023

Nos dias de hoje, muito se discute sobre benefícios como os quais a implementação da Inteligência Artificial (IA) pode apetrechar nas corporações e no dia a dia das pessoas. Nota-se que a Polícia Militar do Paraná (PMPR), apesar de possuir uma gama de recursos tecnológicos, padece por falta de incorporação de ferramentas capazes de auxiliar e melhorar o trabalho dos militares estaduais. Nesta linha, a criação de Centros de Treinamento de Realidade Virtual (CTRV), sala tecnológica dotada de sistemas que conseguem projetar situações parecidas com as enfrentadas no dia a dia de trabalho, munidos de equipamentos de adaptados, poderá, ao propor cenários realistas, aprimorar as habilidades dos policiais, por meio de repetição e prática, todavia em ambiente seguro com o qual consiga treinar ilimitadamente. O objetivo deste presente artigo é analisar a relevância de se introduzir CTRV com vislumbre de aperfeiçoar o combate aos criminosos, lapidando a qualificação da tomada de decisão do policial ao situar-se em um ambiente sob pressão, com o qual deva raciocinar com rapidez, visto que ambientes virtuais conseguem simular situações reais em locais seguros. Ademais, serão estudados o proveito de tal inserção para a segurança pública, bem como para o servidor, o qual terá acesso a impressos comunicando seu desempenho, podendo assim,  identificar áreas de melhoria e alinhamento de suas habilidades de forma mais eficiente. Ao longo deste artigo, objetiva-se, também,  apresentar elementos que corroboram com a mencionada implantação, revelando a real melhoria não apenas dos serviços prestados à população, mas também para a destreza dos servidores, proporcionando-lhes, assim, mais resguardo e  amparo para o desempenho de seus deveres.

A Comparative Study of the Irrigated Zones of Jaguaribe-Apodi and Morada Nova from a (Un)Sustainable Perspective
Authors: Souza Tavares Jessie Coutinho de , Ciarlini Teixeira Roberto Ney , Tassigny Mônica Mota
Published: October 2023

Large-scale government-sponsored irrigation is a feasible alternative to the development of semiarid regions, such as Northeastern Brazil, provided perennial rivers and reservoirs are available. Brazilian irrigation projects have also generally promoted the participation of farmers as informed agents in the process, encouraging training and education towards agribusiness. The purpose of this explorative and descriptive study was to analyze and compare the sustainability characteristics of the Jaguaribe-Apodi and Morada Nova irrigation zones in light of the triple bottom line model (Elkington, 2012), based on information from 18 interviews conducted in September 2015 to November 2015 and submitted to discourse analysis. Triple bottom line sustainability envisages a balance between three dimensions: social, environmental and economic. Such a balance was not observed in our study due to insufficient awareness of environmental issues. However, focusing on a specific context and moment in time, the exploratory study design made it difficult to extrapolate our findings. Future studies could expand the discussion on the sustainability of irrigation zones by using data triangulation in longitudinal designs.
KEY ROLE OF FOSSIL SEAWATER IN NEOGENE SEDIMENTARY ROCKS FOR LANDSLIDE OCCURRENCES IN THE NORTHERN PART OF CENTRAL JAPAN
Authors: Watanabe Naoki , Sato Hisanori , Nishiyama Nariaki , Furuya Gen
Published: October 2023

The south-western area of Niigata Prefecture has the highest landslide densities in Japan. Saline groundwater emerges from several landslides in this area and is an influential factor in the occurrence of these landslides. The geochemical approaches to groundwaters and application of the electromagnetic surveys for landslide slopes revealed the hydrogeological structure of the large-scale landslides which was located on the outlet of saline waters from deep reservoirs and landslide-prone area where wide zonal distributions of saline water at depths of more than 50–100 m and fresh water at depths of shallower than 50–100 m. It is most likely that the saline groundwater behavior emerging in large-scale landslides is controlled by injections of the geo-pressured saline waters from deep reservoirs. The injection of the geo-pressured waters into the landslide mass likely results in excess pore pressure, which is a possible cause of landslide occurrence. On the other hand, the shallow fresh groundwater is inferred to be meteoric water of origin that replaced the saline groundwater, which likely weakened the shear strength of bedrocks, resulting in landslides. Thus, pore saline water plays an important key role in the occurrence of landslides, both large-scale landslides with low frequency and common landslides.

Published: October 2023

Wind Farm Podveležje is located on the plateau Podveležje, about 10 km east of the city of Mostar, in the center of the Herzegovina-Neretva Canton. The Wind Farm consists of 15 wind turbines, each with a power of 3.2 MW, making a total capacity of 48 MW.
The geological structure of the surrounding area on the Podveležje plateau is very complex due to its intricate tectonic complex, ranging from layered to thinly layered Upper Cretaceous limestone with Turonian-aged radiolites as the bedrock. Cracks are often highly prominent, filled with rock weathering products, terra rosa and clay material. During geological and geotechnical investigations at foundation locations, caverns were identified in certain places. The program of additional works (destructive boreholes and TV logging) was carried out to delineate the cavern locations on WT-3, WT-4, WT-8, WT-12, WT-15, and WT-16 plateaus.
The aim of the paper is to describe the cavern rehabilitation at locations of wind turbine foundation including substrate preparation, filling procedures, mixture composition, and performing destructive boreholes to verify rock mass compactness.

To create a spatial plan for Srebrenik City, geological and engineering-geological surveys were carried out. A detailed engineering geological map of the terrain was prepared based on the results of all previous research. A graphic visualization of the field was developed based on the survey, presented through a map of the slope, an engineering geological map, a map of the terrain's stability, and a map of construction convenience. Zoning space was used to determine and allocate favorable and safe terrain for building construction. The paper describes an innovative concept for terrain research, taking into account various factors that determine urbanization conditions. This work has shown the importance of studying the earth's environment, natural slopes, and slope processes (shedding, sliding, landslides, etc.) when planning, designing, and building capital and other construction facilities.
THE EARTHQUAKE IN STOLAC APRIL 2022., CAUSE, PREVENTION AND CONSEQUENCE
Authors: Nikolić Toni , Zekan Sabid
Published: October 2023

On the April 22, 2022. at 11:07 p.m., an earthquake occurred with the epicentre in the area of Berkovici Municipality, at a depth of 5 km, magnitude M 5.7 according to Richter. The same was felt throughout BIH, but also in the wider region. It caused the collapse of chimneys, damage to buildings and landslides in parts of the slopes, so that the residents of eastern Herzegovina (Stolac, Capljina Ljubuski, Berkovici, but also Mostar) spent the night on the streets. The municipality of Stolac suffered significantly, with one victim and several injured due to landslides, which were triggered during the earthquake. An earthquake of this magnitude is always followed by a relaxation of the ground, so that during a period of a few months afterwards Stolac and its surroundings were shaken by dozens of smaller earthquakes, which caused additional anxiety among the residents of Stolac.
According to the research carried out on the spot and the information obtained, cases of rock falls are not a rare case in these areas. The causes of landslides are different, from heavy rains, strong winds, temperature fluctuations and earthquakes, as was the case here. Geologically speaking, the tern is made of crumbling, chalky dolomite and limestone. Since they are located in an outcrop, with a large slope, over 65 degrees, and the objects are located immediately below the slope, then this explains the "shelling" of objects with stone projectiles during any of the above-mentioned hydrological-geological changes.
As we are dealing with a significant number of residential buildings, it is necessary to record the terrain in detail as soon as possible and determine which is the most efficient and economically profitable way of stabilizing the slope above the buildings, i.e. the installation of walls and rock catchers at the foot of the slope, which would in a certain way secure objects from similar engineering-geological processes in the future and protect the lives of the inhabitants of this area.

INFLUENCE OF THE CHANGE OF THE STRESS-DEFORMATION STATE ON THE CALCULATION OF SLOPE STABILITY
Authors: Ribić Nedžad , Zekan Sabid , Hodžić Mersudin
Published: October 2023

The paper presents an analysis of the stability of the slope, where the stress-deformation state of the slope was taken into account before the disturbance of natural conditions, i.e. before any excavation and disturbance of the natural balance, and an analysis of the same stresses after excavation was performed. A slope that is unstable and has a high intensity of movement was taken for analysis. For the first time in the analysis of slope stability, geotechnical models were created as a hybrid that includes the existence of two separate methods, the finite element method and the limit equilibrium method. The finite element method was used to analyze the stress-strain state, and the limit equilibrium method was used to analyze the safety factor. The analysis of the slope in the above manner led to the fact that in the calculation of the stability of the slope, attention must be paid to the appearance of crack systems, which is a consequence of changes in the stress-deformation state of the massif before and after excavation.
GEOTECHICAL ASPECTS OF THE 2020 YEAR MW6.4 PETRINJA EARTHQUAKE AND SOME REMEDIATION WORKS
Authors: Zlatović Sonja , Matešić Leo , Mihaljević Ivan
Published: October 2023

Magnitude MW6.4 Petrinja earthquake on 29 December 2020, caused liquefaction in the fields, under some houses, under some bridges, damages to some roads and bridges, several levees, some landslides and rockfalls, and wide opening of sinkholes.
Several levees along the Kupa and Sava rivers were damaged – mostly longitudinal cracks were noticed near or on the body of those levees, often followed by sandy soil ejected to the surface – on these locations some layers of soil containing sand were discovered on the depth of 5 to 8 m, which obviously liquefied during the earthquake – causing strong movements of the levee body, cracking and lateral spreading. Designs of the solutions are shown with changes made due to the very unfavourable weather conditions in long and heavy periods of rain. Design of a soil improvement is shown for a bridge which suffered settlelments due to liquefaction of the foundation soil. An example of successful foundation is shown – of a reservoir on a soil improved by gravel columns – which helped the pore pressure dissipation after the earthquake.
The paper gives some information on other investigation and other remediation works.

The relationship between geopolitical risks, renewable energy and economic growth in OPEC+ countries
Authors: Belloumi Mounir , Aljazea Ahmed
Published: October 2023

The geopolitical risk (GPR) can be described as the risk connected with some crisis (e.g., wars, terrorist attacks, and conflicts between nations). Besides many other characteristics, OPEC+ countries are prone to risks and uncertainties. According to Bloom (2009) uncertainty is a broader concept that reflects ambiguity in the minds of decision-makers and policymakers about the possible future that spreads across macroeconomic to microeconomic levels. For instance, volatilities in GDP growth and oil prices affect investment decisions, plants' production schedule and individual's consumption habits. Researchers use different proxies of uncertainty that ranges from economic data such as volatility of oil prices, stock markets and GDP to news published in daily papers (Baker, Bloom, and Davis, 2016) since its broader existence implies no specific measures (Bloom, 2009). Extent empirical literature affirms significantly negative effects of uncertainty on the entire economy. Caldara and Iacoviello (2018) have introduced a new-based global uncertainty index, which covers country-specific and region-specific uncertainties measures. They included all words, linked with geopolitical tensions and are exogenous to macroeconomic uncertainties, published in 11 prominent newspapers. This geopolitical risk (GPR) index identified events such as 'Paris assaults', 4 'Iraq invasion', 'tensions during Gulf Wars', and '9/11 WTC attacks in USA'. Geopolitical risks such as wars, terrorist acts, military attacks, or diplomatic conflicts around the world are of major concern to businesses, financial market participants, public media, and policy makers. Considering the novelty and the significance of GPR, we investigate the impacts of geopolitical risks on three key elements of OPEC+ countries that have also global implication: economic growth, oil prices and energy exports.

Authors: Rangsaritvorakarn Nattaphon , Fakkhong Korawit , Iamchuen Niti
Published: October 2023

The study used the Analytical Hierarchy Process (AHP) tool combined with the Map Overlay Model to determine the appropriate evaluation criteria for establishing a second airport in Chiang Mai province, Thailand. The researchers collected data from 17 previous studies and consulted with five experts to establish the main criteria and to create a suitable map display. They then used a pairwise comparison matrix (PCM) to evaluate 16 sub-criteria and collected decision-making data from four experts. The study found that the Social Criteria had the highest weight (0.499), followed by Topography (0.231), Safety and Risk (0.142), and Environment (0.127). The Distance to Main Transportation was the most critical sub-criteria (21.34%), followed by the population in the area (14.54%), slope (13.01%), Distance from Flood history (9.04%), Wind speed (7.21%), and Distance from the residential region (6.04%). Finally, the researchers used the Overlay tool and found approximately 5,825,231 square meters for Average Suitability, 280,876,398 square meters for Good Suitability, and 88,868,024 square meters for Excellence Suitable Area. This is beneficial for state enterprises in planning which location is suitable for establishing a new airport to reduce passenger congestion. Furthermore, the study can serve as a reference for the establishment of new airports in developing countries in the future.

The Combined Effects of Marketing Strategies and Environmental Factors on Tourist Satisfaction: Does E-Commerce Matter?
Authors: Ismail Fadillah , Imran Muhammad
Published: October 2023

This research investigates the impacts of marketing strategies (product, price, promotion, and physical evidence) and the environment on tourist satisfaction in Malaysia by focusing on the moderating influence that e-commerce has in the relationship between environment and tourist satisfaction. Following a quantitative research approach, a structural equation modeling technique called partial least squares structural equation modeling (PLS-SEM) was employed to evaluate the hypotheses. For data collection, a questionnaire was used, and a total of 330 completed questionnaires were included in the study. The findings revealed that the presence of physical evidence had no impact on the level of satisfaction experienced by tourists. However, a positive correlation was found between product, price, promotion, and environment. In addition, the findings also indicate that the association between the environment and tourist tourists is not affected by the presence of e-commerce. Through an investigation into the moderating effects of e-commerce on the relationship between environmental factors and tourist satisfaction, this research aims to significantly expand the academic understanding of the impact that marketing strategies and environmental factors have on tourist satisfaction. In conclusion, it is assumed that the outcomes of this study would give adequate insight to scholars and marketing managers in the tourism industry. The findings' implications and further study potential directions are also highlighted.

Macroeconomical and Microeconomical Aspects of Technology Transfer
Authors: Aleksejs Hilkevics
Published: October 2023

Technology transfer (TT) is the transfer of research results from universities to the commercial sector. The macroeconomic aspects of technology transfer are related to the impact of TT on the technological constant, therefore, on gross domestic product and all major macroeconomic indicators, and on the economic growth of the country as a whole. The microeconomic aspects of technology transfer are related to the behavior of companies in harnessing scientific and technological advances to promote new products on the market. The problem of technology transfer is relevant due to the fact that the main factor for the growth of the economy of modern developed countries is not the growth of capital and labor, but the growth of the technological level. From the point of view of management theory, the first important peculiarity of the technology transfer process is due to the fact that several actors are involved in the process, the three main ones being academia (universities and research institutions), the business environment (enterprises) and public administrations. All participants in the process are relatively independent, have different goals and different value systems, all participants have at their disposal the resources to achieve their goals. Representatives of the business environment in the process of technology transfer are interested mainly in such results that are related to the creators of business success. For representatives of academia, universities and research centres in the process of technology transfer, such results are important that relate to the general successes of the academic environment – number of scientific publications, reports at scientific conferences, scientific awards. Representatives of public sectors in the technology transfer process are most interested in the quality indicators of public administration.

The rise of social commerce has altered consumer purchasing behaviour, but little study has been conducted to investigate the aspects that drive it. This study employs Chen, Lu, and Wang's (2017) model, which is based on social learning theory, to examine the influence of consumers' acquisition of knowledge on important features in social commerce components (SCCs) on their cognitive and affective attitudes, as well as their intentions to make purchases. This study discovered that cognitive and affective assessments are markers of purchase intention in a survey of 417 Gen Z social commerce users in Indonesia, with affective evaluations having a stronger effect. Furthermore, affective evaluations are subject to influence from several factors such as the use of forums, communities, ratings and reviews, and social recommendations. Similarly, cognitive evaluations are impacted by ratings, reviews, and social recommendations. The results of this study indicate that social recommendations have a significant impact on both affective and cognitive evaluations. In contrast to prior studies, it has been found that the influence of information acquired from forums and communities on affective judgement is rather minimal, while its impact on cognitive judgement has yet to be substantiated.

ESG performance and the Cost of Equity: Evidence from South-East Asia
Authors: Tharavanij Piyapas
Published: October 2023

This study analyzes the effect of ESG (Environmental, Social, and Governance) performance ratings on the cost of equity in South-East Asia, both individually and in aggregate. The implied cost of equity (ICC) based on various models is used as a proxy of a true cost of equity. The ESG rating data are from Refinitiv. The panel regression is applied to relate ICC to ESG rating scores and relevant explanatory variables. This paper examines the following five South-East Asian markets: Indonesia, Malaysia, Singapore, Thailand, and the Philippines. We find that firms with better ESG ratings do not necessarily have lower cost of equity as the effects of each ESG component are not the same. Environmental rating (E) and Social rating (S) are not statistically significant in determining the cost of equity. Only Governance rating (G) has a statistically significant negative relationship. The implication is that a firm that aims to lower its cost of equity does not need to invest in all aspects of ESG but should focus more on improving its governance.

21st Century Language Learners' Perceptions and Expectations of Self-Directed Language Learning Apps to Enhance their Listening Skills
Authors: Azirah Ismayatim Wan Faizatul , Ab Wahab Nursyuhada' , Ahmad Azrin Raimi , Zamri Nur Adibah , Yunus Melor Md
Published: October 2023

It is now very impressive how technology has transformed the way 21st-century learners learn and acquire new language skills through listening lessons. It was from listening to the audio that teachers played using a CD player during language lessons, to using headphones and getting the chance to listen to audio or even videos available on various online language learning platforms or mobile applications. It was from the traditional method that used pen and paper to answer listening comprehension questions to only clicking their choice of answers on the mobile phone screen. In today's world, where students' lives cannot be separated from technology, students not only have the chance to get access to millions of authentic audio and videos online from all over the world but also have the freedom and flexibility to pause, stop or replay the video according to their needs which gives the learners the freedom to control and self-direct their own learning. Self-directed learning refers to a teaching approach where students take more responsibility for their own learning and take an active role in setting their own goals, seeking out resources and materials, and evaluating their own progress.

Cumhuriyetin 100. Yılında Sürdürülebilir Su Kullanımında Yeşil Alan Tasarım ve Yönetiminin Etkinliğinin Araştırılması: Ankara Dikmen Vadisi Örneği
Authors: ÜNLÜKAPLAN Yüksel , TİĞİZ Betül
Published: October 2023

Bu çalışmada, Ankara İli Çankaya bölgesinde yer alan ve geniş ölçekli yeşil alana sahip park niteliğinde olan Dikmen Vadi etaplarındaki yeşil alanlarda ihtiyaç duyulan sulama suyu ve kullanılan şebeke suyu miktarının ve Dikmen Deresi Havzasından yağmur hasadı ile elde edilecek potansiyel su miktarının hesaplamalarının yapılmasıyla birlikte yeşil alanların tasarlanması ve yönetiminde suyun etkin kullanımına yönelik önerilerin geliştirilmesi hedeflenmiştir. Bu amaçla Dikmen Deresi Havzasından yağmur suyu hasadı ile geçirimsiz yüzeylerden 1.542.220 m3 potansiyel su miktarı toplanabileceği hesaplanmıştır. Vadi etaplarındaki bitkisel ve yapısal mevcut durum irdelendiğinde ise, vadi etaplarının sezonluk yeşil alan su ihtiyacının 414.180 m3, şebekeden temin edilen suyun 543.268 m3 ve sulama suyu maliyetinin 2021 yılı birim fiyatı dikkate alınarak hesaplandığında yaklaşık 2.000.000 TL olduğu hesaplanmıştır. Çalışmada Dikmen Deresi Havzası genelindeki yeşil alanların sezon boyunca ihtiyaç duyduğu sulama suyunun sadece % 16’sının, Havza genelinden yağmur hasadı ile toplanacak potansiyel su ile sağlanabileceği saptanmıştır. Diğer bir ifade ile vadi etaplarındaki tüm yeşil alanların sezon boyunca ihtiyaç duyduğu sulama suyunun, Dikmen Deresi Havzasından yağmur hasadı ile toplanacak potansiyel suyun sadece % 27’si ile sağlanabileceği, geri kalan kısmı ile de yapılması planlanan IV. ve V. etaplardaki yeşil alanların sulanmasında kullanılacak şekilde planlanmasının suyun sürdürülebilir kullanımı için son derece önemli olduğu sonucuna ulaşılmıştır. Dikmen Deresi Havzasından sadece çatı yüzeylerinden toplanacak su ile seçenekli olarak, günlük 48.172 m2 çim alan, 150.539 m2 yer örtücü ve çiçeklik alan, 30.488 m2 yeşil alan sulanabildiği gibi, III. Vadi etabındaki tüm yeşil alanların da sezonluk su ihtiyacı karşılanabilmektedir. Çalışmada kent ölçeğinde geniş yeşil alana sahip bir parkın sulanmasında suyun sürdürülebilir kullanımı için kurakçıl peyzaj ilkelerini temel alan bir planlama ve proje anlayışının uygulanması gerektiği sonucuna ulaşılmıştır. Aynı zamanda geçirimsiz yüzeylerden toplanabilecek yağmur hasadı sularının tekrardan kullanılması ve değerlendirilmesi halinde yeşil alan sulamalarında ciddi bir tasarruf sağlanacağı da çalışmada ulaşılan bir diğer önemli sonuçtur.

Published: October 2023

Tourism plays a crucial role in shaping the economic, social, and environmental landscapes of destinations. However, its impact on local communities often remains a subject of concern. Understanding local people's perceptions of tourism is essential for sustainable tourism development. Metaphors have important functions in learning people's perceptions. However, metaphors have not attracted sufficient attention from tourism researchers as data sources. This paper explores the metaphorical representations used by local residents to articulate their thoughts and emotions regarding tourism. By analyzing these metaphors, it is aimed to gain deeper insights into the complex and multifaceted relationship between tourism and host communities, thereby informing effective strategies for responsible and sustainable tourism management. Qualitative methodology was used to explore this phenomenon. The participants were local people in Dereli, Turkey. Data were collected using a semi-structured questionnaire and processed through content analysis. Next, the metaphors found in the answers were categorized into different groups.
