Authors: Hadi Kasnawi Al , Budianto Arif , Alhadawiah Sabila , Fidya Karina Alma , Rahayu Satutik
Published: December 2024

VOC is a group of organic compounds that easily evaporate into the atmosphere and have various impacts on human health and the environment. Human exhaled breath and VOC is related to each other. The concentration of VOC differs from an abnormal condition to other abnormalities. However, there is limited information or study about VOC concentration in human exhaled breath. In line with this, this study aims to develop a VOC meter or a measurement system using a CCS811 sensor for human exhaled breath. This study used a CCS811 sensor, a microcontroller, and a suction pump installed inside a sensor box. The system was calibrated using filtered and non-filtered air. The system was tested using varying flow rates. At the final test, the system was tested to measure VOC levels in human exhaled breaths. The results show that the VOC measurement system can measure VOC levels in different air conditions for both filtered and non-filtered air. The use of different flow rates influences the system's performance. The highest sensitivity level is obtained at 0.7 m/s of the flow rate of the suction pump. The system was also able to measure VOC concentrations of the human exhaled breath with concentrations of 0 ppb to 1156 ppb. The VOC concentrations of human exhaled breath depend on many factors that should be further analyzed, including the medical treatment history, food consumption, placebo effect, and many other parameters.

Authors: Tessarolo Marcela , Ziller Joana , Malini Fabio Luiz
Published: December 2024

Este artigo tem por objetivo cartografar os afetos sobre o tratamento precoce contra a covid-19, na timeline discursiva no Facebook. Para isso, partimos de revisão teórica sobre o cenário comunicacional na sociedade da plataforma, estudamos os afetos medo e esperança e a sociedade da desinformação. Coletamos em páginas e perfis públicos, no Facebook, as palavras “tratamento and precoce”, via CrowdTangle, no período de 29 de junho a 8 de julho de 2020, e analisamos os atores e as narrativas com mais engajamento. Políticos (38%), empresas de mídia (26,7%) e páginas de ativistas de direita (12,7%) foram os atores com mais engajamento no período. Houve disputa de significado do termo “tratamento precoce”. Para muitos, denotava esperança de cura. Para outros, uma afronta à ciência, uma promessa de cura sem respaldo em estudos científicos.

Authors: Santiago Glaucia Helena de Paula , Nardino Fernanda , Machado Rita Rangel de Souza , Lima Fernando Lopes Tavares de
Published: December 2024

A cobertura vacinal contra o papilomavírus humano no Brasil está aquém das metas do Ministério da Saúde. O objetivo do estudo aqui apresentado foi analisar os discursos sobre a vacina contra o papilomavírus humano presentes na rede social X em 2023 no Brasil, visando aprimorar a campanha de vacinação. Realizou-se a análise do discurso, de Pêcheux, de um tweet com argumentação favorável e outro contrário à vacinação, além de toda a interação gerada com outros usuários. Observou-se que o conhecimento da população sobre o tema é limitado, havendo disputa de sentidos entre grupos favoráveis e contrários à vacina. Apesar do X ser um terreno fértil para a divulgação de notícias falsas e teorias conspiratórias sobre a vacinação, ele pode ser também uma ferramenta para avaliação e aprimoramento da campanha de vacinação, desde que as instituições científicas e governamentais se façam presentes nesse espaço, operando com a mesma competência comunicacional que os influenciadores.

Authors: Reche Sérgio Antônio Mendes , Barbosa Neto Jair Borges , Caseli Helena de Medeiros , Frizzo Heloísa Cristina Figueiredo
Published: December 2024

This study examines changes in occupational performance as observed in posts by university students on a social network. Depression is prevalent in Brazil, particularly among students, impacting academic and daily functioning. Using CrowdTangle, anonymous Facebook posts were analyzed following American Occupational Therapy Association guidelines. 301 posts revealed occupational changes across seven areas defined by the association. Depressive symptoms hinder academic performance, exacerbating symptoms. Academic stress, loneliness, stigma, loss of leisure interest, and socioeconomic factors contribute to distress. Social engagement and support benefit mental health, while time constraints detrimentally affect academics, especially disadvantaged students. The study underscores the link between occupational changes, academic decline, and depression, proposing six relevant subcategories within the Education domain.
TRANSPORTATION: CHALLENGES AND OPPORTUNITIES FOR DEVELOPING SUSTAINABLE FOOD MARKETS (THE CASE OF GEORGIA)
Authors: Kharaishvili Eter , Gechbaia Badri , Goletiani Ketevan
Published: December 2024

Introduction. The paper analyses the three pillars of transportation and evaluates the development models of the transportation system. It is evident that transportation plays a crucial role in the development of food markets. The level of transportation infrastructure has a direct impact on the improvement of food accessibility and the process of forming a sustainable food market. Furthermore, transportation can greatly contribute to inclusive economic growth, diversification of exports, introduction of innovations, reduction of costs, minimisation of food losses, and so forth. The allocation of resources towards the development of transportation infrastructure, particularly in relation to the export of Georgian agri-food products to international markets, is regarded as a crucial strategy for fostering sustainable food markets. Aim and tasks. The principal aim of this paper is to identify the challenges inherent in the transportation of foodstuffs and to determine the opportunities that will encourage the formation of sustainable food markets. To this end, an analysis of the transportation sector was undertaken. The "urgency-impact" matrix was employed to identify the challenges inherent to the field of food transportation, while the "priorities scheme" was utilised to ascertain the potential avenues for the sustainable development of transportation and food markets. Research results. The paper concludes that there is a positive correlation between the indicators of the development of transportation and sustainable food markets. Nevertheless, this is inadequate to affect economic growth. The overcoming of challenges in the research area will facilitate improvements in transportation and the diversification of food markets, particularly in Europe. Conclusion. The paper presents conclusions regarding the challenges inherent to the transportation of foodstuffs and proffers recommendations for the advancement of sustainable food markets through the surmounting of these challenges.
YOUTH PERCEPTIONS TOWARDS ENTREPRENEURSHIP IN SOUTH AFRICA
Authors: Madondo Elvis , Tinonetsana Faith
Published: December 2024

In South Africa, the field of youth entrepreneurship is confronted with considerable obstacles, many of which are rooted in the country's historical economic inequalities, which were further exacerbated by the apartheid era. This study aims to gain insight into the perceptions of youth regarding entrepreneurship by employing the Entrepreneurial Event Theory (EET) to analyse these perceptions through the lenses of desirability, feasibility, and propensity to act. EET was used to provide a structured understanding of how attitudes towards entrepreneurship, perceived capability and propensity to act influence entrepreneurial engagement. The thematic analysis of qualitative data from semi-structured interviews revealed that while South African youth have a strong desire to use entrepreneurship to address unemployment and economic inequality, their active engagement is limited. Participants expressed high aspirations for entrepreneurship due to its potential for financial independence and personal fulfilment. Nevertheless, this enthusiasm is tempered by perceived feasibility concerns, including challenges related to financial resources, regulatory complexities, and intense market competition. Moreover, the propensity to act varies; some young people demonstrate a proactive attitude, while others are hesitant due to perceived risks and systemic barriers. The study recommends integrating comprehensive entrepreneurship education across all educational levels, launching national and community-level campaigns to promote an entrepreneurial culture and showcase success stories, and advocating for policies to enhance access to funding. These measures aim to improve the overall feasibility and increase the propensity to act among South African youth, thereby fostering a more vibrant entrepreneurial landscape.
EXPRESS METHOD FOR CALCULATING GROSS MARGIN IN E-COMMERCE: A PRACTICAL APPROACH
Authors: Zalizniuk Viktoriia , Nozhovnik Oleh
Published: December 2024

The purpose of this study is to present a streamlined approach to calculating the gross margin of online stores, with a particular focus on addressing the specific requirements of small and medium-sized enterprises (SMEs) within the e-commerce sector. This research presents a comparative analysis between the traditional method of gross margin calculation and an express approach that utilises the average order value (AOV) as a central metric. The objective of this study is to evaluate the efficiency and accuracy of the express method, particularly in the context of SMEs that may lack the resources required for more complex financial analyses. Methodology. A quantitative research design is employed, utilising data from three online retailers specialising in the sale of home textiles and linens produced by an in-house sewing studio. The shops in question operate on a number of e-commerce platforms, including Rozetka, Etsy, eBay, and Prom.ua. The study encompasses a period of eight months, during which sales data was collected and analysed in order to evaluate the efficacy of both manual and express methods of gross margin calculation. The express method incorporates statistical analysis, including z-scores and normal distribution, to provide a probabilistic framework for the assessment of the likelihood of achieving target gross margin ranges under different pricing scenarios. Results. The findings of the study indicate that the express method suggests a probability of achieving a gross margin within the 25-30% range, with a 38.11% likelihood. A case study utilising tulle curtains demonstrates the practical application of the aforementioned method. Following the implementation of a 20% discount, the gross margin experienced a notable decline, from 33.9% to 17.36%. Furthermore, the results of the z-score analysis indicate that the probability of exceeding a 30% gross margin is 27.43%, while the likelihood of the margin falling below 25% is 34.46%. This analysis underscores the inherent risks associated with offering discounts and illustrates the potential for significant fluctuations in profitability contingent upon price adjustments. Practical implications. The express method offers invaluable insights that can inform decision-making in a range of retail contexts. To illustrate, an online fashion retailer may utilise the method to evaluate the influence of price increases on gross margin during seasonal promotions. Similarly, a home goods store could employ the method to ascertain the impact of a flash sale discount on profitability, thereby facilitating the balancing of margins with sales volume. Value / Originality. The express method introduces a novel approach by integrating AOV and probabilistic analysis into gross margin calculation. This offers a dynamic framework that accounts for variability in discounts and sales, which is a significant advantage over traditional methods that rely on fixed margin targets or historical averages.
ON THE PATH TO THE EU: STRENGTHENING ECONOMIC RESILIENCE OF UKRAINE’S JUSTICE AREA
Authors: Kolomoiets Tetiana , Agapova Olena , Orzechowski Marcin
Published: December 2024

This study examines the process of integrating public administration entities within the Justice Area into the European Union's legal and administrative framework, with a particular focus on the economic dimensions of these transformations. It is widely acknowledged that the enhancement of administrative and legal regulation is of paramount importance for the attainment of EU membership, as it serves to promote both institutional efficiency and economic stability. The accelerated legislative adaptation amidst the ongoing war serves to illustrate Ukraine's resilience in aligning its governance structures with EU standards, with the objective of improving public administration efficiency, human rights protections and economic sustainability. The research identifies key reforms in the justice sector, including the digitalisation of legal aid, modernisation of the penitentiary system and streamlining of the notarial process. These reforms are not only advancements in the judicial system but also strategic steps to attract foreign investment by improving the rule of law and reducing corruption. The economic benefits of these reforms include increased investor confidence, more optimal resource allocation within the justice system, and cost reductions through digital transformations. The study's key findings highlight the role of public administration entities in fostering economic stability. For example, reforms in insolvency and restructuring, in accordance with EU Directive 2019/1023, serve to enhance the resilience and efficiency of the business climate. Furthermore, initiatives to modernise forensic services and digitise justice processes have the additional benefit of reducing systemic costs, thereby promoting transparency and economic competitiveness. The study reaches the conclusion that Ukraine's integration into the European Justice Area is as much an economic endeavour as it is a legal and administrative one. The reinforcement of public administration mechanisms in the justice sector serves to bolster macroeconomic stability, facilitate sustainable development and position Ukraine as a pivotal economic partner within the European legal and financial ecosystem. These endeavours illustrate a dedication to harmonising governance and economic frameworks with EU standards, thereby ensuring mutual benefits for both Ukraine and the EU.

Authors: Sofyan Azinar , Tamtelahitu Jopie , Nikijuluw Jeanee B
Published: December 2024

Isu kemiskinan hingga saat ini masih terus diperdebatkan berbagai kalangan dan pemerhati masalah kemiskinan. Dimana, kemiskinan dimaknai sebagai ketidakmampuan seseorang atau sekelompok orang dalam memenuhi kebutuhan pokok. Kajian-kajian terkait kemiskinan selama ini menyoroti variabel makro ekonomi. Sementara, kenyataannya geografis wilayah Maluku merupakan wilayah kepulauan. Sehingga, penanganan kemiskinan pada wilayah kepulauan memerlukan strategi tersendiri dibandingkan penanganan kemiskinan pada wilayah kontinental. Metode penelitian yang digunakan adalah Systematic Literature Review. Pendekatan ini melibatkan serangkaian langkah terstruktur untuk mengidentifikasi, mengevaluasi, dan mensintesis temuan dari berbagai sumber literatur yang relevan. Proses ini di awali dengan menetapkan kriteria inklusi dan eksklusi untuk memilih studi yang akan dianalisis. Hasil penelitian menggambarkan jika, Kemiskinan menjadi permasalahan yang bersifat multidimensional sehingga upaya penanganannya tidak hanya dapat mengandalkan faktor ekonomi semata saja. Akan tetapi memerlukan beragam penanganan dengan turut melibatkan masyarakat. Kemiskinan pada wilayah kepulauan selama ini masih erat dikaji melalui variabel makro ekonomi, seperti pertumbuhan ekonomi, pengangguran, pertumbuhan penduduk, ketimpangan pendapatan dan sebagainya. Terlebih lagi, upaya penanganan yang dilakukan pemerintah seringkali belum tepat sasaran yakni masyarakat miskin. Hal tersebut makin diperumit dengan kenyataan bahwa, daerah kepulauan memiliki kelemahan terkait konektivitas antar pulau pada wilayah kepulauan tersebut. Sehingga upaya penanganan kemiskinan melalui kebijakan dan program kerja pada wilayah kepulauan perlu mempertimbangkan konektivitas antar pulau.

Aspetti stilistici e tecnici
Authors: Valenti Devis , Restiani Federica
Published: December 2024

The restoration of Nicolò di Pietro’s frescoes (doc. 1394‑1427) in the apse of the church of Santi Maria e Donato in Murano (Venice) was carried out in 2022. It allowed an in-depth study of stylistic and technical aspects of this work of art, created by the painter in his mature years. Despite the poor state of conservation, the close-up view allowed us to recognize the high quality of the details painted by Nicolò (i.e. Evangelists’ faces), while a large part of the painted surface can be attributed to his workshop. Furthermore, the removal of the wooden choir made possible the discovery of some unknown fresco fragments in the lower sector of the apse. The restoration was also an opportunity to study past restorations of this decorative cycle and techniques of mural painting in fifteenth century Venice.

The Meaning of the Form and Substance of Music from the Perspective of John Dewey's Art Philosophy
Authors:   Korean Music Education Society, Kim Gi-Su
Published: December 2024

This study attempts to grasp the meaning of the form and substance of music from the perspective of John Dewey's art philosophy. John Dewey's art philosophy takes nature containing primary contribution and reality as its category. Nature acts as the source of all art's existence as well as the occurrence of form. The organization of nature's vital energies becomes a condition of form. Under this condition, the form of music is always a method of revealing the meaning of music as a fluid, dynamic, and processive aesthetic experience, and the body of music becomes a new and reinforced meaning of music made to be known. Therefore, from the perspective of Dewey's art philosophy, the form and substance of music are possible not as any intellectual structure or frame but as an aesthetic experience, and anyone who experiences music can possess a musical meaning. This ideological perspective not only solidifies the cornerstone of the philosophy of modern music education of ‘music for all people’ but will also serve as an important factor for the aesthetic experience of music as an experience that cultivates metaphorical ability, an essential competency in the AI era.

The purpose of this study is to explore implications for the internalization and quality of university music liberal arts education. The subjects of the study were a total of 183 male and female undergraduate students who had participated in an appreciation-based music liberal arts class at a four-year university in Region A, Korea, and participants were analyzed according to appreciation activity, emotional empathy, positive emotions, class participation and satisfaction factors that can have an effect on music learning flow and intention to continue learning. Results of the study, First, time spent appreciation to music, number of music viewing activities per year, other-oriented emotion, subjective experience, and individual involvement were positively significant for learning flow. Second, individual engagement, satisfaction with instructors and assessments were found to have a significant static effect on intention to continue learning. I propose continued discussion and research on practical education from various perspectives, including the development of teaching strategies for liberal arts music learning outcomes, strengthening of support systems, and network-based communication and empathy.
Musical Feature Perception: A Comparative Study Among Musicians, Dancers, and Non-musicians,
Authors: Winston Jim Saroj , Uppunda Ajith Kumar
Published: December 2024

Music and dance are two art forms that depend on musical components to produce an output. The
training usually starts at a young age, and the skills are fine-tuned through rigorous practice. Longterm
musical or dance training has been associated with enhancements in various sensorimotor domains
compared to non-trained laypeople. However, few studies have directly compared musicians’
and dancers’ performances for musical perception tasks. In the present study, we administered Mini-
PROMS on 152 participants comprising formally trained musicians, dancers, and nonmusicians/
dancers and recorded their performance in subtests of melody, tuning, tempo, and accent discrimination.
The total score was computed as a composite of scores from the subtests. The results
revealed a significant advantage for musicians only in the task of melody discrimination and not for
other subtests or total scores. We also observed that the performances of a subgroup of nonmusicians
were at par with musicians and dancers to be identical in the total scores. Dancers performed at par
with musicians in untrained domains like accent. The findings suggest that cultural factors and innateness
influence music perception. In addition, long-term musical and dance training leads to distinct
enhancements in non-trained domains, hinting at a trans-modality transfer of skills.
Adapting Rhythmic Movement in Dondang Sayang: Melody and Movement Matching Analysis
Authors: Ismail Md Jais
Published: December 2024

This study aims to analyze the adaptation of rhythmic movement in dondang sayang by examining
its melodic and rhythmic structures. While previous research has extensively explored the lyrical
content and melodic compositions of dondang sayang, there has been limited focus on the theoretical
relationship between its melody and rhythmic elements. To address this gap, this study reviews ex-
isting literature and connects the elements of rhythmic movement with the musical framework of
dondang sayang. Despite dondang sayang’s deep roots in Malay culture, its rhythmic movements
can effectively manifest the musical structure and convey the song’s message. This research demon-
strates how rhythmic movement is intricately blended into dondang sayang, resonating with the aes-
thetic principles of Malay music culture. By providing a detailed analysis of the interplay between
melody and rhythm, this study contributes to a deeper understanding of how traditional music inter-
acts with rhythmic movement, accommodating and molding each other to create a new form of
aesthetic expression. It has the potential to enhance both the performance and the audience’s expe-
rience, indirectly enriching and strengthening dondang sayang as a Malay cultural heritage for future
generations.
A Biographical Study of William Banda Makulloluwa's Contributions
Authors: Samarasinghe Kamani
Published: December 2024

William Banda Makulloluwa (1922–1984) was a musician in Sri Lanka who made a significant con-
tribution to preserving Sinhalese music. He dedicated his scholarly pursuits to the investigation of
Sinhalese music and the cultural intricacies of Sri Lanka. Undertaking extensive fieldwork from the
1960s to the 1980s, he methodically documented and studied traditional music, with a particular
emphasis on various communities in Sri Lanka. The objective of this study is to investigate the con-
tribution of Makulloluwa’s musical style, expectations, and ideologies to elevate Sri Lankan tradi-
tional music. The study is based on the narrative method of qualitative research. Interviews, records,
autobiographies, various reports, and books written by Makulloluwa were used to collect data. Seven
in-depth semi-structured interviews were conducted in November and December 2022 and January
2023 to gain a better understanding of his musical style, expectations, and ideologies. Non-probabil-
ity purposive and snowball sampling were used as the sampling method. Content analysis was used
to evaluate the data. Research revealed that he used techniques such as recording, documenting,
rearranging, and educating to safeguard the distinct Sinhalese musical melodies. He established a
formal framework for community singing, which helped to establish the foundation for Sinhalese
traditional music. He assumed the task in a proactive manner as a musician, showing genuine interest
in recording and conserving Sinhala traditional tunes. He worked very hard to locate, preserve, and
share these tunes with the next generation. This study emphasizes Makulloluwa's unwavering com-
mitment to the growth and preservation of Sri Lankan folk dance and music.

En esta investigación, exploramos cómo un grupo de 21 futuras maestras de primaria atiende, interpreta y decide basándose en el pensamiento algebraico evidenciado por niñas al resolver igualdades numéricas. Nos situamos en las perspectivas conceptuales del noticing y el MTSK para profundizar en el conocimiento profesional de las participantes. Las futuras maestras participaron en una asignatura sobre la enseñanza y el aprendizaje del álgebra escolar, la cual siguió la metodología del análisis de vídeos. Los principales resultados muestran que las participantes consideran los elementos algebraicos involucrados en la situación, aunque el uso de evidencia es limitado. Además, destacamos la movilización de diversos conocimientos matemáticos para la enseñanza del álgebra escolar.

The present study captures the pressure exerted by the population on the Apuseni Natural Park (ANP), from the perspective of the significant role of the human component in the conservation and development of these fragile areas from a natural and human point of view. The proposed study is focused both on the quantitative characteristics (general density, physiological density, pasture load) and on the quantitative ones (naturality index, human pressure through forestry), analyzed at the level of the ANP. The analysis of these indicators highlights the fact that, from the point of view of the human pressures exerted at the level of the ANP, it is not a strong one, and moreover it can jeopardize the optimal use of the potential of the ANP.
Stabilisation of the Track’s Subgrade Foundation by Injection in the Case of Degradation of Permafrost Soils
Authors: Razuvaev D. A. , Pechenkin R. S.
Published: December 2024

The location of the railway infrastructure on permafrost increases risks of emergence of defects and deformation of the subgrade. In Russia permafrost occupies approximately 65 % of the country’s area. Consequently, defectiveness of subgrade in the Eastern part of railway network of Russia exceeds the network’s average.

The objective of the study was the increase in the efficiency of stabilisation of track subgrade’s foundation with injection method under the conditions of degradation of permafrost soils.

An improved algorithm for designing pressure injection of cement-soil grout, implementing an integrated approach, is proposed for railway subgrade operated under conditions of degradation of permafrost soils and formation of soft soils in foundations.

A laboratory experiment was set up and carried out to determine the amount of heat released by injected grout of various composition due to the exothermic reaction of hardening of cement, that allowed determining a linear dependence of the specific heat release of injection grout on the cement content.

A new calculation scheme with an equivalent layer of grout in the stabilisation area has been proposed to predict the amount of thawing of permafrost foundation soils when injecting materials with a cement binder, and an analytical solution to the problem under consideration has been proposed for preliminary calculations.

The article is dedicated to the anniversary of Academician Vladimir Nikolaevich Obraztsov, who largely contributed to organisation of domestic transport science and founded a scientific school of designing railway stations and transport junctions, and who was a leading specialist in the field of railway operation, a prominent public figure, and a Professor at MIIT. The professional and creative activity of a talented educator and scientist is closely connected to the history of the country’s largest transport university - Moscow Institute of Transport Engineers (MIIT), now Russian University of Transport. The stages of a scientist's professional path are examined using materials from the institute's newspaper «Stalinets». V.N. Obraztsov had worked at MIIT for almost 50 years, created a scientific school, trained dozens of students and was the head of the country's first department of stations and junctions.
Eosinophilic Esophagitis: A Comprehensive Review of Pathogenesis, Diagnosis, and Management.
Authors: Khan Zmarak
Published: December 2024

There has been an extraordinary development in our understanding of eosinophilic esophagitisover the last twenty years. This is a chronic immune system disorder that occurs when there is anincrease in the numbers of eosinophils in the esophagus, leading to inflammation and symptomssuch as chest pain and heartburn and most prominently, dysphagia which refers to food beingstuck in the esophagus. It is usually linked to allergies such as food allergies and asthma. Thediagnosis normally entails endoscopy and biopsy of the esophageal tissue for diagnosis. Thetreatment of this disease involves dietary control to avoid allergens, drugs like proton pumpinhibitors or topical steroids and occasionally esophageal dilation. Initially, research focused ondefining characteristics of the disease and the evaluation of its impact. Recent studies changedthis tendency by identifying particular risk factors that could facilitate development of thedisease. In this paper we seek to solidify the current fundamental understandings of this disease,resulting in a comprehensive knowledge base. Moreover, the paper analyses different modalitiesof treatments effectiveness as well as implications of untimely therapy.Keywords: Food allergens, Elimination diet, Fibrosis, Esophageal strictures, Biopsy findings,Dysphagia, Treatment options, Diagnosis, Eosinophilic esophagitis.
Euler inversion: Locating sources of potential-field data through inversion of Euler's homogeneity equation

Earth scientists can estimate the depth of certain rocks beneath Earth's surface by measuring the small disturbances that they cause in the Earth's gravity and magnetic fields. A popular method for this is Euler deconvolution, which is widely available in geoscience software and can be run quickly on a standard computer. Unfortunately, Euler deconvolution has some shortcomings: 1) the approximate shape of the rocks must be known, for example, a sphere or a wide flat slab, represented by the structural index 2) the depth of the rocks is not well estimated when there is noise in our data, which is a common occurrence. We propose a new method, Euler inversion, which fixes some of the shortcomings of Euler deconvolution by using more adequate (and complex) mathematics. Our method is less sensitive to noise in the data and is also able to determine the approximate shape of the source (the structural index). Euler inversion is also fast to execute on a standard computer, making it a practical alternative to Euler deconvolution on an Earth scientists toolbox.
Reinforcement learning is positively associated with anhedonia symptoms
Authors: Liang Shiyi , Wimmer G. Elliott
Published: December 2024

Impairments in reward-related behavior are characteristic of major depressive disorder and closely linked with anhedonia. While previous research has suggested a negative relationship between reward-related behavior and symptoms of depression or anhedonia, findings across clinical and non-clinical studies are mixed. To investigate this relationship, we conducted three online studies with a combined sample of over 600 participants. Participants completed reinforcement learning tasks which involved the selection of either the more rewarding response or more rewarding stimulus. Contrary to expectations, we consistently observed a positive association between reinforcement learning performance and anhedonia symptoms across all studies: an exploratory study, a preregistered replication, and an independent dataset utilizing a different learning task. Depression symptoms overall showed only weak positive associations with performance. Our results contrast with the assumption of a negative association between reward-related task behavior and symptoms of depression or anhedonia. Instead, our findings in large non-selective samples suggest that anhedonia symptoms can be positively associated with reward-guided behavior.
