Published: September 2024

In dealing with the COVID-19 pandemic situation, the learning and assessment process is required without meeting face to face. So optimizing the use of ICT must be done. One of them is in the learning process and physics assessment using the Whatsapp (WA) online application. A total of 30 respondents who are students of SMA IT ANNISA Kadungora, conducted research and data collection using questionnaires, observations and interviews. Respondents filled in data through WA chats and links sent to WA group chats. The results show that 40% feel very helpful, 53% are helped and 7% are quite helped in the communication of learning facilities. Then 7% felt very helpful, 86% helped and 7% was quite helped in the delivery of learning materials. The data received by utilizing this WA does not reduce the value obtained compared to face-to-face. It is even able to increase learning motivation through interaction, improving the quality of communication and discussion between learning actors. Optimizing the use of ICT by using WA greatly facilitates the learning and assessment process. In addition, the respondents were very enthusiastic and suggested that they apply it to other lessons. This study also shows the need for further research on the effect of using WA on student achievement.Dalam menghadapi situasi pandemic covid-19, proses pembelajaran dan penilaian diwajibkan tanpa bertatap muka secara langsung.

Published: September 2024

Due to modern requirements for environmental protection, introduction of environmentally friendly power engineering technologies involves search and development of new energy sources. One of the ways to meet these requirements and maintain the same level of energy production by thermal power plants is to use multicomponent fuels. The most promising and affordable heavy fuel oil from the point of view of energy, ecology and economy are coal-water slurries (CWS). In this regard, the study of the properties and characteristics of such fuels is relevant. The coal-water slurries have been prepared in a rotary hydrodynamic cavitation generator. A pneumatic atomizer with external mixing is used to spray the coal-water slurries. Interferometric Particle Imaging method is used to determine the average size of fuel droplets after atomization. The authors have conducted experimental studies of the characteristics of atomization of coal-water slurries based on lignite and pyrogenetic liquid with a pneumatic atomizer with a tangential supply of a spraying agent. A three-stage method to prepare lignite-based slurries with pyrogenetic liquid has been tested. It has been established that when using this technique, the fluidity of coal-water fuel is maintained even with the introduction of 20 % by weight of pyrogenetic liquid into the composition of coal-water slurries when replacing both water and coal in equal proportions. The kinematic viscosity of coal-water suspensions increases when pyrogenetic liquid is added, despite a decrease in the concentration of the solid component. The change of suspension density is insignificant. The results of the study of atomization process have shown that the tangential air supply to the atomizer leads to an increase of the jet spraying angle by 6° compared with direct supply. At the same time, the average droplet size in the jet of a two-component CWS with direct air supply is 8 % smaller. The results of the study have made it possible to obtain completely new knowledge that can significantly advance domestic and world science and technology in the field of power engineering, namely the technology of coal-water fuels atomization. Experimental studies have determined the main patterns of influence of the CWS properties and the method of spraying agent supply on the formation of a gas-drop jet. Such patterns will provide conditions for the effective atomization of quite viscous CWS in the combustion chambers of energy boilers. The results obtained will enable designers and constructors to develop highly efficient designs of steam and hot water boilers and gasifiers fueled by CWS.

To ensure the operability of a circuit with three-phase pulse width modulation, it is necessary to meet the conditions of operability. One of the most important conditions is to exclude the phenomenon of overmodulation. To obtain the boundary values of the variables that determine the quality of modulation, it is necessary to study the phenomenon of overmodulation in various modes of operation of a three-phase converter. New modulating functions with constraints have been introduced to analyze the phenomena associated with overmodulation. Methods of analysis of electrical circuits have been used. The processes of three-phase pulse width modulation in the overmodulation mode have been studied. An assessment of the effect of overmodulation on the variables that determine the quality of the modulation process has been made. The boundary amplitude coefficient of a three-phase bridge has been determined, at which a three-phase overmodulation mode occurs. The results can be used to develop algorithms for controlling frequency converters in frequency control systems of electric drives.

This research investigates the scheduling of tasks in real-time to optimize energy use in the context of integrating renewable energy sources into the smart grid. The primary goals are to analyze the influence of fluctuations in renewable energy on grid synchronization, evaluate the efficiency of different optimization methods, and identify significant obstacles and corresponding remedies. Secondary data studies advanced forecasting methods, energy storage systems, and optimization techniques, including Linear Programming (LP), Dynamic Programming (DP), and metaheuristics. The significant findings show that renewable energy fluctuations affect power system stability. Advanced prediction methods and energy storage are essential in reducing these impacts. Optimization approaches enhance the scheduling efficiency, but the computational complexity and practical application constraints limit their effectiveness. Challenges such as frequency regulation, voltage management, and integrating Distributed Energy Resources (DERs) need specific solutions such as dynamic voltage support and grid modernization. The policy implications include supporting advanced technologies, encouraging real-time scheduling system research, and enhancing grid infrastructure to increase resilience. These measures are essential for integrating renewable energy, ensuring a reliable smart grid, and achieving a sustainable future.
Neurodivergent Spatialities: A Geographical Reading of Recent Empirical Work in Neurodiversity Studies
Authors: Olund Eric
Published: September 2024

Neurodivergent people often feel they don’t belong. This is not just an emotional response to neurotypical norms, but a matter of “misfit” embodiment in particular places (Garland-Thomson, 2011). Recent empirical research adopting a neurodiversity critique is beginning to examine neurodivergent spatialities in increasingly substantive ways. Often space is a static container for the discourses and practices that shape neurodivergent people’s lives. Unmarked whiteness often accompanies this approach to space. However, space becomes a much more active presence when examining the experiences of racialized neurodivergent people. Strategies of spatial containment have long been central to regulating racialized and other oppressed groups. However, “container-space” on its own is inadequate for understanding the different risks and outcomes that different neurodivergent individuals face, especially when exhibiting neurodivergent comportment and emotions. Other work builds on these critical insights by seeking to affirm neurodivergent ways of relating to the world. Here, often borrowing from ideas of queer and crip time, scholars show how space can shape how people are continually becoming as embodied subjects over time. This scholarship invites us to ask how specifically neurodivergent forms of agency might emerge from the mutual relationship between embodiment, time and space. Deeper engagement with material space through intersectional thinking and more robust attention to space when exploring alternative temporalities are needed not only to understand how neurodivergent people can be misfits, but also how they may thrive.
Crecer en movimiento: desafios y oportunidades para la primera infancia migrante
Authors: Lopez Boo Florencia , van der Werf Cinthia , Daga Giuliana
Published: September 2024

En la última década, los flujos migratorios en América Latina y el Caribe (ALC) han crecido notablemente, caracterizándose por movimientos migratorios complejos que incluyen migración de origen, tránsito, destino y retorno. Este fenómeno ha tenido un impacto profundo en las familias y, especialmente, en los niños en la primera infancia (de cero a cinco años). La migración parental produce efectos mixtos en los niños que se quedan atrás: aunque el incremento del ingreso familiar puede beneficiarlos, la ausencia de los padres puede afectar negativamente su desarrollo emocional y cognitivo. Para los niños migrantes, la evidencia sugiere un desarrollo cognitivo y socioemocional más pobre debido a la falta de estímulos y el estrés del viaje y la adaptación. Los niños nacidos en el país de destino enfrentan tanto oportunidades como desafíos, incluyendo dificultades en el acceso a servicios de salud y educación, así como el estrés asociado al riesgo de deportación. Este documento examina la evidencia sobre la relación entre migración y primera infancia a nivel mundial, con un enfoque especial en la región de ALC. Se destacan los desafíos que enfrentan estos niños y se proponen recomendaciones de políticas públicas que se adapten a las diversas necesidades de los niños migrantes. Entre las políticas más prometedoras destacadas en la literatura se encuentran las intervenciones familiares, los servicios basados en centros y el apoyo en salud mental para los cuidadores, todas ellas diseñadas para mejorar el desarrollo cognitivo y socioemocional de los niños migrantes.

V prispevku smo opisali primer razvoja aplikacije RAG (Retrieval-Augmented Generation). Za jezikovni model smo uporabili Chat GPT-4o. Aplikacija COBISS Lib, ki jo uporabljajo knjižničarji, podpira postopke nabave monografskih in serijskih publikacij ter elektronskih virov, obdelavo podatkov o zalogi, izvajanje postopkov v izposoji in medknjižnični izposoji itd. Ker je aplikacija in dokumentacija obsežna, smo poskusili razviti asistenta, ki bi knjižničarjem pomagal pri vsakodnevnem delu. Razvili smo programe v Javi 21, ki so markdown datoteke priročnikov razbile po odstavkih. Za vsak odstavek smo od ChatGPT zahtevali, da pripravi povzetek. Nato smo za vsak tak povzetek pripravili vektor ter ga shranili v vektorsko bazo. Ko uporabnik postavi vprašanje, od ChatGPT zahtevamo, da generira vektor in zazna jezik uporabnika. V vektorski bazi poiščemo pet (nastavitev) najbližjih vektorjev/besedil (cosine similarity) glede na iskalni vektor. Nato od ChatGPT zahtevamo, da za uporabnikovo zahtevo na osnovi najdenih besedil generira odgovor v zaznanem jeziku. Razvili smo Javanski odjemalec do ChatGPT z uporabo odprtokodne knjižnice OpenAI-Java. Nismo pa uporabili popularne javanske knjižnice langchain4j, ki ima podporo za veliko število različnih modelov, podporo za izločanje odstavkov, tokenizacijo, generiranje vektorjev itd. Celotno pot smo želeli prehoditi sami in pri tem dobiti lastne izkušnje.
A hypothesis about interrelations of epigenetic factors and transposable elements in memory formation
Authors: Mustafin R. N.
Published: September 2024

The review describes the hypothesis that the drivers of epigenetic regulation in memory formation are transposable elements that influence the expression of specific genes in the brain. The hypothesis is confirmed by research into transposon activation in neuronal stem cells during neuronal diﬀerentiation. These changes occur in the hippocampus dentate gyrus, where a pronounced activity of transposons and their insertion near neuron-specific genes have been detected. In experiments on changing the activity of histone acetyltransferase and inhibition of DNA methyltransferase and reverse transcriptase, the involvement of epigenetic factors and retroelements in the mechanisms of memory formation has been shown. Also, a number of studies on diﬀerent animals have revealed the preservation of long-term memory without the participation of synaptic plasticity. The data obtained suggest that transposons, which are genome sensors highly sensitive to various environmental and internal influences, form memory at the nuclear coding level. Therefore, long-term memory is preserved after elimination of synaptic connections. This is confirmed by the fact that the proteins involved in memory formation, including the transfer of genetic information through synapses between neurons (Arc protein), originate from transposons. Long non-coding RNAs and microRNAs also originate from transposons; their role in memory consolidation has been described. Pathological activation of transposable elements is a likely cause of neurodegenerative diseases with memory impairment. Analysis of the scientific literature allowed us to identify changes in the expression of 40 microRNAs derived from transposons in Alzheimer’s disease. For 24 of these microRNAs, the mechanisms of regulation of genes involved in the functioning of the brain have been described. It has been suggested that the microRNAs we identified could become potential tools for regulating transposon activity in the brain in order to improve memory.
A study of the influence of the T2DL.2DS-2SS translocation and the 5S(5D) substitution from Aegilops speltoides on breeding-valuable traits of common wheat

The use of the gene pool of wild relatives for expanding the genetic diversity of common wheat is an important task of breeding programs. However, the practical application of common wheat lines with alien genetic material is constrained by the lack of information on chromosomal rearrangements and the negative impact of the transferred material on agronomically important traits. This research is aimed at studying 14 introgression lines with the T2DL.2DS-2SS translocation and the 5S(5D) substitution from Aegilops speltoides obtained from crossing common wheat varieties (Aurora, Krasnodarskaya 99, Nika Kubani) with the genome-substituted form Avrodes (BBAASS). Hybrid lines with diﬀerent combinations of T2DL.2DS-2SS and T1BL.1RS translocations and 5S(5D) substitution were characterized by resistance to leaf and yellow rusts, productivity components and technological qualities of grain. The assessment of the varieties’ resistance to rust diseases showed that Krasnodarskaya 99, Nika Kubani and the Aurora variety, which is a carrier of the T1BL.1RS translocation, are highly susceptible to diseases, while the presence of the T2DL.2DS-2SS translocation and the 5S(5D) substitution, both together and separately, provides resistance to fungal pathogens. The analysis of the lines using markers designed for known resistance genes of Ae. speltoides did not reveal the presence of the Lr28, Lr35 and Lr51 genes in the lines. The results suggest that the genetic material of Ae. speltoides transferred to chromosomes 2D and 5D contains new resistance genes. To determine the eﬀect of the T2DL.2DS-2SS translocation and the 5S(5D) substitution on the productivity and technological qualities of grain, the lines were assessed by weight of 1000 grains, grain weight and number of ears per 1 m2, by protein and gluten content, gluten quality and general baking evaluation. A positive eﬀect was determined upon the weight of 1000 grains, protein and gluten content. There were no signiﬁcant diﬀerences in other characteristics. The T2DL.2DS-2SS trans-location and the 5S(5D) substitution did not have a negative eﬀect on the productivity and technological quality of grain, and are of interest for breeding practice.
Variation among Blackgram (Vigna mungo L.) Genotypes for Antioxidant Defence System and Yield under High Temperature Stress
Authors: Pavithra N. , Jayalalitha K. , Sujatha T. , Harisatyanarayana N. , Lakshmi N. Jyothi , Roja V.
Published: September 2024

Background: Blackgram is a short duration pulse crop which is sensitive to high temperatures. Raising global temperatures are becoming a serious threat to the production of blackgram by altering biochemical processes at cellular level. Hence, the present investigation was carried out for better understanding of genotypic variability and the biochemical mechanisms governing heat stress tolerance which can help in identifying heat tolerant blackgram genotypes that can yield better under climate change scenarios. Methods: Thirty blackgram genotypes selected from temperature induction response technique were evaluated for biochemical efficiency under natural high temperature conditions during summer, 2022 and 23. Field experiment was conducted at Agricultural College Farm, Acharya N.G Ranga Agricultural University, Agricultural College, Bapatla. Biochemical and yield parameters were recorded at flowering and the data were analyzed statistically and pooled. Result: The results of the study revealed that the genotypes TBG-129, LBG-1015, PU-1804 and PU-31 recorded higher seed yield indicating their ability to withstand high temperatures by up-regulating various biochemical pathways involved in increased production of proline, carotenoids and antioxidant defense enzymes that might have scavenged the free radicals that were produced due to high temperature stress, thereby preventing lipid peroxidation. Lower seed yield was recorded in TBG-125 and LBG-1023 which might be due to oxidative damage caused by higher accumulation of free radicals and poor scavenging activity of antioxidant enzymes. Moreover, the results of correlation analysis revealed that all the biochemical traits such as proline, carotenoids and antioxidant defense enzymes showed positive association with seed yield except free radicals and malondialdehyde. The principal component analysis results revealed considerable variability among the traits accounting for 80.0%. The genotypes TBG-129, LBG-1015, PU-1804 and PU-31 can be used in breeding programmes for development of heat tolerant genotypes.
Evaluating the Impact of UVC Exposure on Forage Maize Seeds under Hydroponic Condition
Authors: Palacio Jose Alfredo , Cadavid Bayardo Emilio , Quintero Edwin García
Published: September 2024

Background: UV radiation, with shorter wavelengths than visible light, plays a pivotal role in stimulating growth processes and boosting the synthesis of beneficial compounds in plants. Moreover, it triggers morphological changes and genetic responses, shaping plants’ physical traits and adaptability. Nevertheless, a nuanced understanding is necessary as excessive UV exposure can also cause harm, underscoring the complexity of the relationship between UV radiation and plants. The study aimed to evaluate the effect of ultraviolet C (UVC) light exposure on the germination and growth of forage maize seeds under controlled conditions in an indoor crop. One sample of seeds was exposed to UVC light, while the other was not. Methods: The experiment was carried out for 14 days, with the plants subjected to mixed blue-red light, fertigation and kept at a maximum external temperature of 30°C and maximum internal temperature of 25.1°C. UVC light is applied for 10 minutes to the seeds before germination. Result: The results showed that the plants exposed to UVC light had an average growth increase of 3cm compared to those that did not receive the treatment. However, the protein content of both sets of seedlings was similar. The study suggests that further research is necessary to determine the optimal duration and distance for UVC exposure to minimize any potential negative effects on the plants. It also highlights the need to investigate the effect of UVC radiation on the nutritional content of hydroponic crops to ensure that the increased growth does not come at the expense of nutritional quality. The experiment was carried out in Medellin, Colombia, with a maximum solar radiation of 1000 W/m2 and an altitude of 1500 meters. Overall, the study provides evidence that UVC radiation can enhance the growth of hydroponic maize seedlings, but more research is needed to fully understand its effects. At the end, there is an improvement in the growth of forage corn in seeds that have been subjected to UVC light compared to those that have not. It is worth highlighting the need for more research on changes in nutritional components in general.

Published: September 2024

Jember Regency has great potential in the agricultural sector, with cassava being one of its key commodities. Cassava can be developed into MOCAF (Modified Cassava Flour), produced through a fermentation process that modifies cassava cells using lactic acid bacteria. The development of the MOCAF agroindustry in Jember Regency has promising prospects due to the abundant availability of raw materials and increasing market demand. However, supply chain management optimization is necessary to ensure the effectiveness and efficiency of MOCAF agroindustry development. This study aims to generate effective and efficient strategy recommendations for developing the MOCAF agroindustry. The study uses the Interpretative Structural Modeling (ISM) method to determine the most dominant supply chain actors and the Analytical Hierarchy Process (AHP) method to determine the priority strategies for MOCAF agroindustry development. Based on the identification results, the MOCAF supply chain structure consists of four members: cassava farmers, collectors, MOCAF producers, and consumers. Farmers and cassava collectors act as suppliers of raw materials to producers, who then process them into MOCAF and sell them to consumers. The main actor in the supply chain is the consumer the party who determines the sustainability of the MOCAF agro-industry. Meanwhile, the most appropriate and prioritized supply chain development strategy is partnering with farmers to strengthen institutions within the supply chain. This strategy aims to improve the effectiveness and efficiency of relationships among supply chain actors, especially between the MOCAF agroindustry, farmers, and cassava collectors. This partnership is expected to ensure product quality, increase efficiency, stabilize, and even reduce the price of raw materials, which can increase the demand for MOCAF. Other strategies resulting from the AHP analysis are complementary to encourage the increase in MOCAF demand.

Authors: Kurniasari Lia , Kertasurya Martha Irene , Nugraheni Sri Achadi , Agushybana Farid
Published: September 2024

Background: Low birth weight (LBW) remains a significant global health issue, leading to higher rates of infant and child morbidity and mortality. In 2022, Indonesia had a 12.58% rate, while in Kutai Kartanegara Regency, East Kalimantan, the rate was higher at 16.30%. The Covid-19 pandemic, which severely impacted East Kalimantan also influenced LBW rates.
Objectives: Analyzed the determinants of LBW incidence during the Covid-19 pandemic in Kutai Kartanegara.
Methods: This population of 1265 mothers delivered in four public health centers with the highest cases of BBLR. This study used a case control design for 240 mothers, including 120 mothers who gave birth to babies with low birth weight and 120 mothers who gave birth to babies with LBW. Data were obtained from e-cohort data according to specific inclusion and exclusion criteria. Data collection occurred from August until October 2022 through interviews with structured questionnaires and maternal child handbooks. Data analysis was performed with logistic regression.
Results: Determinant factors LBW were maternal nutritional risk (upper arm circumference <23.5 cm) (OR=2.800, 95% CI=1.237-6.340), history of anemia (OR=3.156, 95% CI=1.716-5.804), history of Covid-19 (OR=4.357, 95% CI=2.355-8.063), living with a smoker (OR=2.505, 95% CI=1.716-2.804), and not having health insurance (OR=2.744, 95% CI=1.435-5.247).
Conclusions: Internal factors such as age, under arm circumference, anemia, Covid-19, birth spacing, and parity and external factors (such as living with smokers, not having insurance) were interconnected in contributing to the risk of LBW, the pandemic further influenced these determinant factors.

Published: September 2024

Background: The presence of anemia in pregnant women significantly affects the health of both mothers and their fetuses. Around 37% of pregnant women worldwide experience anemia. In the Community Health Center of Tanjung Sekayam, the prevalence of anemia in women at the third trimester of their pregnancy was notably high, at 50.4%.
Objectives: This study aims to identify the risk factors for anemia in women at third trimester of pregnancy in the working area of the Community Health Center of Tanjung Sekayam Subdistrict, Sanggau Regency.
Methods: This study was an observational research with a case-control design. The study population consisted of 153 women at third trimester of pregnancy, receiving antenatal care in the Community Health Center of Tanjung Sekayam. The samples included 62 respondents, selected through a simple random sampling, comprising of 31 cases and 31 controls. Data were collected using questionnaires and analyzed with the Chi-Square test to assess the factors associated with the occurrence of anemia.
Results: There was a relation among maternal age (p=0.000; OR=22.9), interpregnancy interval (p=0.024; OR=6.9), parity (p=0.011; OR=2.2), nutritional status (chronic energy deficiency) (p=0.000; OR=11.3), compliance (p=0.021; OR=3.9), and knowledge (p=0.001; OR=8.2) and the prevalence of anemia in the third trimester. However, the family support did not show any significant relation.
Conclusions: Maternal age, pregnancy interval, parity, nutritional status, compliance with iron tablet intake, and knowledge are related to the prevalence of anemia in third trimester of pregnancy. Family support did not show any significant relation with the incidence of anemia, possibly due to the limitations in measuring the family support itself and other factors, such as discomfort in consuming iron tablets and forgetfulness. More structured interventions and intensive education on the importance of iron and nutrition during the pregnancy are needed to reduce the risk of anemia.

Published: September 2024

Background: Stunting is a nutrition problem that can slow down the growth. With prevalence at 32.5%, Landak Regency in West Kalimantan has been designated as a stunting hotspot. The lack of a maximum penalty for the stunting case in Landak Regency is not based on factors causing the stunting itself, because there is no identifiable factor causing the stunting in certain area due to narrow roads and sharp curves.
Objectives: The objective of this study was to identify causes and distribution of the stunting case in Landak Regency.
Methods: A total of 330 households in Meranti, Sebangki, and Senakin were included in this cross-sectional study because they were at a risk of the stunting. Toddlers, mothers, health care, and environmental factors were among the found variables. The researchers employed a basic random sampling strategy for the sampling and used the secondary health center data to find out whether or not toddlers were stunted. Researchers in this study collected data on the independent variables by observing and interviewing participants. Using the chi-square test, the data was analyzed.
Results: The results showed that determinants of the stunting in Landak Regency were the history of early breastfeeding initiation (p-value=0.032), exclusive breastfeeding (p-value=0.042), frequency of exclusive breastfeeding (p-value=0.040), the continued breastfeeding (p-value=0.024), complementary feeding (p-value=0.042), immunization history (p-value=0.007), infectious disease history (p-value=0.000), maternal height (p-value=0.046), delivery assistance (p-value=0.000), access to health services (p-value=0.004), the role of health workers (p-value=0.002), and family latrine ownership (p-value=0.000).
Conclusions: Several factors were found to be associated with incidence of the stunting among toddlers in Landak Regency.
Artificial Intelligence in Cryo-EM Protein Particle Picking: Recent Advances and Remaining Challenges

Published: September 2024

Cryo-electron microscopy (Cryo-EM) has revolutionized structural biology by enabling the determination of high-resolution 3- Dimensional (3D) structures of large biological macromolecules. Protein particle picking, the process of identifying individual protein particles in cryo-EM micrographs for building protein structures, has progressed from manual and template-based methods to sophisticated artificial intelligence (AI)-driven approaches in recent years. This review critically examines the evolution and current state of cryo-EM particle picking methods, with an emphasis on the impact of AI. We conducted a comparative evaluation of popular AI-based particle picking methods, using both general machine learning (ML) metrics and specific cryo-EM structure determination metrics. This analysis involved constructing the 3D density map from the picked protein particles and assessing the obtained resolution and particle orientation diversity, underscoring the significant impact of AI on cryo-EM particle picking. Despite the advancements, we also identified key obstacles, such as handling complex micrographs with small proteins. The analysis provides insights into the future development of more sophisticated and fully automated AI methods in cryo-EM particle recognition.

Authors: El-Hajj Mohammed , Pavlova Miglena
Published: September 2024

In today’s data-driven marketing landscape, accurately predicting customer responses to marketing campaigns is critical for optimizing engagement and return on investment (ROI). This study utilizes a Decision Tree (DT) model to identify key factors influencing customer behaviour. Initially, the model achieved a high accuracy of 87.3% but struggled with precision and recall due to class imbalance. By applying a resampling technique, the model’s performance improved significantly, with a recall increase from 44% to 83.1% and an F1-score improvement from 49% to 74.2%. Key influential features identified include how recently a customer made a purchase, the number of days they have been a customer, and the number of previous campaigns they responded to. The study highlights the DT model’s interpretability, making it a practical tool for marketing professionals to improve campaign effectiveness and customer targeting.
Regulatory Role of IL-6 in Immune-Related Adverse Events During Checkpoint Inhibitor Treatment in Melanoma
Authors: Singh Krishna Pal , Singh Anuj , Wolkenhauer Olaf , Gupta Shailendra Kumar
Published: September 2024

The landscape of clinical management for metastatic melanoma (MM) and other solid tumors has been modernized by the advent of immune checkpoint inhibitors (ICI), including programmed cell death-1 (PD-1), programmed cell death-ligand 1 (PD-L1), and cytotoxic T lymphocyte antigen 4 (CTLA-4) inhibitors. While these agents demonstrate efficacy in suppressing tumor growth, they also lead to immune-related adverse events (irAEs), resulting in exacerbation of autoimmune diseases such as Rheumatoid arthritis (RA), Ulcerative colitis (UC), and Crohn’s disease (CD). The immune checkpoint inhibitors offer promising advancements in the treatment of melanoma and other cancers, but they also present significant challenges related to irAEs and autoimmune diseases. Ongoing research is crucial to better understand these challenges and develop strategies for mitigating adverse effects while maximizing therapeutic benefits. In this manuscript, we addressed this challenge using network-based approaches by constructing and analyzing molecular and signaling networks associated with tumor-immune cross-talk.. Our analysis revealed that IL6 is the key regulator responsible for irAEs during ICI therapies. Furthermore, we conducted an integrative network and molecular-level analysis, including virtual screening, of drug libraries, such as the Collection of Open Natural Products (COCONUT) and the Zinc15 FDA-approved library, to identify potential IL-6 inhibitors.. Subsequently, the compound amprenavir was identified as the best molecule that may disrupt essential interactions between IL6 and IL6R responsible for initiating signaling cascades underlying irAEs in ICI therapies.
The Illusion of Competence: A Deep Dive into Workplace False Performance
Authors: Dunnion Marie Frances , Gbadamosi Gbolahan , Francis-Smythe Jan
Published: September 2024

This paper develops an understanding of False Performance as a negative form of workplace behaviour which has received scant attention. According to the quantitative literature, which measures False Performance using the Organisational Charlatan Scale (OCS), false performers are incompetent employees who deliberately portray themselves as better able to perform in a job role than they know themselves to be capable. In this study, False Performance was explored in United Kingdom public sector organisations for the first time, using novel focus group methodology and grounded theory. Eight focus groups (n=51) were conducted to explore employees’ perceptions and experiences of False Performance, with a focus on job interviews and performance appraisals. Using NVivo for analysis, five categories emerged: Co-Worker Perceptions of False Performance in the Workplace, False Performance in Interview/Appraisal Settings, The Impact of Trust on the False Performer, The Effect of False Performance on Co-Worker Morale, and Preventing False Performance in the Workplace. The results support the literature review that False Performance is a new and negative addition to the taxonomies of job performance. Human Resources (HR) managers are, therefore, urged to prevent and reduce False Performance via well-designed selection processes and performance appraisals, thereby improving co-worker trust amongst employees.
