Published: January 2025

Based on initial observations, information from green clam shell collectors that the production of green clams in Kampung Kerang Hijau, Cilincing, North Jakarta, can reach 5 tons/day when the condition of the clams is abundant and can reach 1 ton/day when the condition of the clams is declining. Based on this number, until now green mussels are only used for their meat to be consumed by the community and the waste accumulates in landfills and causes an unhealthy environment for the surrounding community. Based on this background, as an effort to reduce green clam shell waste, improvements need to be made. The purpose of this study is to be able to determine the optimal formulation/composition of green clam shell powder in the manufacture of bricks and to determine the characteristics/properties of bricks produced through testing rules. The method used in this study is an experimental method, carried out by making samples, testing samples, and drawing conclusions with comparative techniques against standards. The results obtained in this study are the optimal composition to produce good quality bricks, namely by using a mixture of 10% fine shell powder on sand. The characteristics or properties of the resulting bricks are with a compressive strength value of 10.26 N/mm2, water absorption of 16.45%, and resistance to nails (not broken or cracked)

Authors: Zhang Yang
Published: January 2025

Conventional information dissemination methods of online media mainly use the Susceptible Infective Removal model to describe the transformation relationship of information dissemination, which is easily affected by false delay stabilization, resulting in a low dissemination influence index. To solve the above problems, this paper proposes an information dissemination method of online media based on semi-supervised learning. That is to locate the source of network media information dissemination and use semi-supervised learning to design the network media information dissemination algorithm, thus realizing the network media information dissemination. The experimental results show that the designed semi-supervised learning communication method of network financial media information has a high communication influence index, good communication effect, high efficiency, and certain application value, and has made certain contributions to improving the comprehensive quality of network financial media information communication.

AI-enabled business analytics has become a game changer in the US tech industry by making it possible for organizations to gain innovation, greater efficiency and competitive advantage, especially in product development. The main focus of this study is on the adoption of more advanced AI techniques like machine learning (ML), natural language processing (NLP), predictive analytics and computer vision to take a look at the impact they have on the four core product development metrics (development speed, product quality, innovation potential and customer satisfaction). The project used a quantitative research design through which data were gathered from 200 U.S.-based tech professionals through a structured survey to better understand organizational practices, outcomes and challenges. Results indicate substantial changes in outcomes of product development, with machine learning emerging as the technique with most impact, especially covering customer satisfaction and predictive capability. Smaller firms observed that not having enough resources, not having enough skilled personnel and even not being capable of achieving data confidentiality are making it difficult for them to adopt AI and, as a result, they rated their satisfaction less than larger organizations, which have already been in front of their technological revolution and possess advanced infrastructure and readiness for AI. Organizational readiness, size and strategic alignment were found to be the significant predictors of AI success and statistical analyses such as chi-square tests, regression analysis and correlation, verified these findings. The study underscores the critical need for pairing AI initiatives with business goals, so that the
results are optimized. The fact remains that the potential for transformation exists and there is still a barrier for the smaller companies in this area who struggle with integration and scalability. Filling a critical gap in the empirical research on AI driven business analytics, this study provides useful insights for policymakers and practitioners involved in the U.S. tech industry in practice while providing a future research agenda for emerging AI technologies that contribute to product development.
Putting the prime in priming: Using prime processing behavior to predict target structural processing
Authors: Tooley Kristen M. , Brehm Laurel
Published: January 2025

Structural priming effects are widespread and heavily relied upon to assess structural representation and processing. Whether these effects are caused by error-driven implicit learning, residual activation, a combination of these, or some other learning mechanism remains to be established. The current study used preexisting data and a novel data analysis approach that links processing at the prime to later processing at the target to better understand the nature of structural priming. This novel analytic approach was applied to total reading times from a previously published structural priming study in comprehension, which provided processing measures of the structurally critical regions of prime reduced-relative clause sentences. These were then used as predictors in a series of hierarchical linear models where analogous processing measures at the target sentence regions served as outcome variables. Separate sets of models were run for prime–target pairs that had the same structure (i.e., abstract priming) and those that had the same structure and initial verb (i.e., a lexical boost). Prime-to-target processing relationships were observed for both types of prime–target pairs, but showed very different patterns. This provides support for the claim that abstract priming effects and the lexical boost are caused by different mechanisms. Additionally, the observed effects were positive and so do not support the error-driven learning prediction that processing difficulty at the prime should lead to greater facilitation at the target. Overall, this novel method provides a new tool for investigating structural priming and processing.
APPROXIMATE METHODS OF RECOVERING THE ANGULAR VELOCITY OF PROJECTILE ROTATION ACCORDING TO DATA OF REFERENCE POINTS
Authors: Bondarenko S.
Published: January 2025

A promising direction for determining individual aerodynamic force coefficients (moments) of a projectile is an approach based on solving the inverse problem of projectile motion dynamics based on experimental data of ballistic firing. In a number of works, the author obtained expressions for calculating the aerodynamic coefficients of the projectile, which functionally depends on the parameters obtained from external trajectory measurements and the angular velocity of the projectile. In addition, the accuracy of determining the aerodynamic coefficients is significantly affected by the change in the angular velocity of the projectile along its entire flight path. In the article, to obtain values of the angular velocity of rotation of the projectile, it is proposed to use a set of reference (pre-reference) points corresponding to the moment of departure from the barrel of the gun at different initial velocities of its flight. Numerical modeling was carried out and the accuracy of the calculation of the angular velocity of rotation of the projectile at reference (pre-reference) points was evaluated using the example of the 155-mm high- explosive fragmentation projectile Assegai M2000. It has been proven that with a relatively small number of shots at different initial speeds of the projectile flight, it is possible to obtain the value of its angular velocity of rotation at reference (pre- reference) points with the average value of the relative error, which is within -(0.01-0.03)%. Procedures for approximating the angular velocity of projectile rotation based on reference (pre-reference) points, as well as procedures for minimizing the error of their approximation, have been developed. It is shown that the obtained approximation functions ensure the passage of their curve through the given extreme reference (pre-reference) points and allow to minimize the errors in the calculation of the angular speed of rotation of the projectile, over the entire trajectory of its flight, in the range of - (0.08-0.3)%.

Published: January 2025

The study of H-Darrieus rotor attracted considerable attention due to its environmental advantages among generating electricity from renewable energy source. However, this rotor present reduced aerodynamic efficiency. In the present study, two-dimensional (2D) computational fluid dynamics (CFD) simulations of vertical axis H-Darrieus wind turbine (VAWT) rotor, characterized by a NACA0018 aerodynamic profile has been conducted using Ansys Fluent software. The air flow around three-bladed wind turbine has been simulated in order to improve the aerodynamic performance of this rotor. The numerical approach adopted consists on the resolution of unsteady Reynolds-averaged Navier-Stokes equations (URANS) applying k-ω shear stress transport (SST) and k-ε Realizable turbulence models. The obtained results indicate a good agreement with the available experimental data in terms of the variation in the power coefficient (Cp) as a function of the tip speed ratio (TSR). Furthermore, the results affirm the superiority of the k-ω SST turbulence model over the k-ε Realizable model regarding Cp which takes maximum values of 36%, 38% and 35% for velocity U∞ equal to 10, 15 and 20 respectively, in the case of k-ω SST. This result is valid also for the velocity magnitude contours. A parametric study has been established based on the variation of the torque coefficient with the azimuth angle, for different values of velocity

The problem of vortex disruption from the cylindrical blades of Magnus wind turbines is an urgent topic, which subsequently reduces the efficiency of the installation. Also, these cylindrical blades have a disadvantage in the form of low lift and high drag, as a result of which low operating efficiency is observed. Thus, the purpose of this work is a numerical study of the addition of a fixed blade to the cylindrical blades of a two-bladed wind turbine. Numerical studies were carried out for various angles of inclination of fixed blades from 0° to 60° using the Realizable k-ε turbulence model. The results of the study showed that with an increase in the angle of inclination of the fixed blade, the flow is disrupted, which is clearly visible at the maximum speed of rotation of the blades and the wind wheel, which causes a drop in lift, leading to a decrease in the efficiency of the wind turbine. Based on this, 0 degrees is the optimal angle of inclination of the fixed blade of a wind farm
Study of Internal Flow with Deceleration in a Cryogenic Chamber Composed of Jet-Type Atomizers
Authors: Arriaga Carpio Ian Lev , Sayán Jasuo , Ronceros Julio , Klusmann Mirko , Raymundo Carlos , Namay Wilder , Ronceros Gustavo
Published: January 2025

The present article delves into the comprehensive study of internal flow dynamics within a cryogenic chamber used for freezing food with high water percent. For cryogenic freezing is necessary to reduce temperature extremely and maintain a uniform distribution, different behaviours may cause structural damages on food. This is because the chamber comprises a circular-sectioned tunnel or chamber coupled with a set of Jet-type atomizers for the injection of liquid nitrogen. The internal flow, predominantly consisting of liquid nitrogen, necessitates prolonged residency within the chamber to uniformly and effectively cool or freeze food traversing its interior. Consequently, the primary aim is to extend the cryogenic fluid's residence time, achieved by strategically decelerating the flow. This deceleration is orchestrated through the strategic injection of the fluid to induce a swirling or vortex effect. The formation of this effect is meticulously executed by positioning the atomizers at periodic intervals around the internal walls of the cylindrical chamber, ensuring a prolonged recirculation of the internal flow. This research endeavour is further augmented by a comprehensive numerical analysis of swirling flow dynamics and associated parameters such as temperature, velocity, pressure and nitrogen-liquid interface. Leveraging the robust capabilities of CFD ANSYS software (Computational Fluid Dynamics), this analysis incorporates sophisticated models including the Volume of Fluid (VOF) model and the k-epsilon turbulence model. Additionally, the construction of a three-dimensional hexahedral mesh, facilitated by ICEM CFD software, adds depth and precision to the numerical simulations. The culmination of this study lies in the profound comprehension of internal flow behaviour and its intrinsic correlation with the design intricacies of the cryogenic system. Variations in nitrogen injection pressures and the strategic deployment of atomizers around the chamber serve as pivotal parameters for elucidating the system's optimal design
Hydrodynamic Analysis of an Eco-Trap to Improve Gross Pollutant Removal on Water Surface with CFD Simulation

Published: January 2025

The use of gross pollutant trap (GPT) as one of the primary treatment measures to remove coarse pollutants from water surfaces that should not enter sewers and waterways is widely recognized worldwide. Over the years, GPT designs have evolved significantly, from large and built-in devices to proprietary off-the-shelf products as a structural measure to curb river pollution. Nevertheless, most of the installed GPTs are poorly maintained, leading to many environmental problems such as odour, vermin, flooding and unsightly views. This study is interested in developing a removable gross pollutant trap, called Eco-trap, which can contribute to river cleaning without much complexity and cost. The hydrodynamic performance of the Eco-trap is evaluated using Computational Fluid Dynamics (CFD) simulations. To ensure the reliability of the simulations, grid independence tests were conducted with coarse, medium, fine and finer mesh sizes. Three different mesh sizes (0.10m x 0.05m, 0.20m x 0.10m and 0.30m x 0.15m) were tested in five velocity scenarios to evaluate their effectiveness in removing pollutants from stormwater runoff. The results provide important insights into the velocity distributions, pressure gradients and force distributions around and on the trap structure, which provides valuable information for optimizing the design of pollutant removal devices. By analysing the total deformation and equivalent stress, net weaknesses were identified for further improvements. This study contributes to the improvement of stormwater management in Malaysia by providing new insights into the hydrodynamic behaviour of gross pollutant removal devices and their potential applications to reduce water pollution in river ecosystems
The Influence of International Standards on National Regulation of Taxation of Digital Services (on the Example of Austria)
Authors: Ageev S. S.
Published: January 2025

The purpose of this research is to study the impact of the OECD international standards regarding the taxation of digital services on national regulation. Currently, there is an imbalance in the distribution of revenues in the form of direct and indirect taxes on digital services between developed and developing countries. This problem is due to the fact that the largest digital companies carrying out cross-border activities are subject to direct taxes not in the country where the service is provided but in the country, in which they are located, that is, in a country with a developed economy. The problem is also aggravated by regulatory arbitrage, which is expressed in different country approaches to the taxation of digital services, which ultimately affects the taxpayer’s choice of the most favorable jurisdiction when providing such services. In this research there were analyzed both the OECD international standards and regulation in Austria and the EU, where a harmonized transition from a national tax model for digital services to a model that complies with these international standards took place. Through the prism of these conclusions, the changing tax policy of Russia was examined in terms of the implementation of the OECD international standards as well as the current regulation of VAT for the provision of services in electronic form. Based on the results of the research, a conclusion was drawn about the potential risks associated with the implementation of the OECD international standards, both for Russia and for developing countries, and the prospects for other harmonized approaches to the taxation of digital services were outlined.

Estudiamos la migración pos nupcial de aves a través de los Pirineos en los puertos de montaña de Somport y Portalet durante 2016 y 2017. Se siguieron cuatro especies: (aves planeadoras) abejero europeo Pernis apivorus, milano negro Milvus migrans y aves batiendo alas, aleteadoras o remeras (avión común Delichon urbicum y golondrina común Hirundo rustica). Las planeadoras utilizaron las horas centrales del día para migrar debido a los flujos térmicos. Las aleteadoras evitaron los fuertes vientos. El abejero europeo migra desde mediados de agosto hasta mediados de septiembre, el milano negro desde mediados de julio hasta mediados de agosto, el avión común desde finales de julio hasta finales de septiembre y la golondrina común desde finales de agosto hasta mediados de octubre. La selección de la dirección del viento es diferente en cada especie. La temperatura es el factor meteorológico más relevante que explica su migración.

The mangrove land cover is undergoing unprecedented anthropization. The main objective of this study is to map and quantify the dynamics of land cover in the Moanda Mangrove Marine Park between 2002 and 2020. Specifically, it aims to: (i) assess the annual rate of change in the mangrove land cover; (ii) estimate the influence of wood energy on the decline in mangrove forest area; and (iii) propose measures for the sustainable management of the Mangrove Marine Park forest. The study method is a combination of field survey, diachronic analysis of Landsat images and statistical analysis. The very good correspondence between the classification results and field reality was justified by the Kappa value (0.81) and overall accuracy (82.4%). The diachronic analysis of satellite images showed the regression of areas covered by forest classes in favor of the anthropogenic activities, herbaceous mangroves and the savannah. The annual deforestation rate in the Moanda Mangrove Marine Park is estimated at around 0.07%. The result points to the heavy dependence of coastal households in Moanda on fishing (31%), agriculture (26%) and charcoal production (22%), all of which put pressure on the natural resources of the Mangrove Marine Park. Promoting an integrated approach and techniques for the sustainable use of natural resources is an effective way of combating deforestation in the Moanda Mangrove Marine Park.

Authors: Gruyer Léa
Published: January 2025

Cet article examine le rôle des influenceurs diététiciens sur Instagram dans la diffusion des recommandations du Programme National Nutrition Santé (PNNS). Depuis 2001, le PNNS vise à promouvoir une politique nutritionnelle nationale et à sensibiliser sur les risques liés à une mauvaise alimentation. Les diététiciens sont identifiés comme des acteurs clés dans cette démarche de sensibilisation. Parallèlement, les réseaux socionumériques (RSN), notamment Instagram, offrent un espace pour la diffusion de messages liés à la santé et l’alimentation. Certains diététiciens, en adoptant une posture d’influenceur, parviennent à construire un modèle économique autour de leurs conseils en nutrition. Il s’agit d’interroger la manière dont l’activité d’influence cohabite avec le discours du professionnel en diététique. La présente étude se concentre sur huit comptes Instagram de diététiciens, analysant la conformité de leurs contenus aux recommandations du PNNS et les implications éthiques et commerciales de leur présence sur les RSN.

Published: January 2025

L’objectif de cet article est de montrer que le développement de la filière d’alimentation à base d’insectes n’est pas un « problème public » (Neveu, 2015). Des analyses des corpus de données portant sur la médiatisation du sujet dans la presse généraliste française (1997-2023) et les pratiques informationnelles des acteurs travaillant dans la filière (conduits en 2023) mettent en évidence le déficit d’information. Celui-ci révèle les différentes logiques et stratégies info-communicationnelles présentes dans la sphère médiatique et professionnelle : la faible publicisation du sujet et l’invisibilisation des risques et des controverses, ainsi que le manque de données spécialisées, qui contribuent de manière concertée à la construction d’un « non-problème » (Henry, 2021)
Free Jazz
Authors: Cotro Vincent
Published: January 2025

Seule œuvre musicale (tous genres confondus) à avoir donné son nom à un courant tout entier, « Free Jazz » reste entouré d’un halo de contradictions et de polémiques qui a obscurci sa réalité musicale et parfois faussé son analyse. Sans contester sa valeur de manifeste ni son caractère révolutionnaire à bien des égards, le présent ouvrage propose de resituer cet album – au format et à l’instrumentation uniques – dans son temps comme dans le parcours d’Ornette Coleman et de ses partenaires. Il en observe les mécanismes les plus fins (thèmes préexistants, improvisation individuelle et collective) à la lumière des deux prises conservées, montrant également comment l’album s’appuie sur les nouvelles ressources technologiques offertes à l’enregistrement (en particulier la stéréophonie). Un panorama est également proposé tant de la réception de « Free Jazz » que de ses conséquences immédiates ou plus lointaines. L’ouvrage invite en définitive la lectrice et le lecteur à réfléchir à la façon dont s’invente un album « historique » mais aussi, en dépit de son caractère encore déroutant aujourd’hui, à en risquer une écoute entière et attentive.

The aim of the study was to evaluate the influence of online exams on the following: (i) ability to motivate students to study for their upcoming summative exams, (ii) adoption of online mode of assessment by the students and (iii) educational outcomes with respect to the confidence that may be attached to the judgements.  Methods: We conducted online assessments for two batches of postgraduate Medical Biochemistry students: nine second-year and eight third-year Master of Science (M.Sc.) students of our institute. Online feedback forms were administered to the students and the teachers after declaring the exam results.  Results: The teachers were not fully convinced about the usefulness of online assessments. The teachers strongly prefer tests under supervision and were of the opinion that malpractices can be reduced by questions from higher levels of cognition during the online assessments. The students found online assessments highly useful in their learning process. The adoption of online assessment by the students and its impact on the educational outcomes were found to be inferior to the conventional exams. The scores of the students in online exams were comparable with their previous in-class internal assessment scores as well as with their scores in the final university exams.  Conclusion: It is suggested that online assessment is a suitable tool for promoting the learning process. It can also serve as an effective tool for summative assessments; although its educational outcome and the readiness to adopt are inferior to conventional exams.

Published: January 2025

Introduction: Despite being a certifiable competency, students find it difficult to learn communication skills effectively. Learner initiated individualized strategies can be developed by students by making utmost use of strengths and opportunities while minimizing the weaknesses and threats. Application of SWOT analysis (strength, weakness, opportunities and threats analysis) by students for establishing learning strategies could be evaluated for its effectiveness in improving learning outcomes. Methods: After seeking IEC approval, baseline formative assessment for prescription communication was conducted. Participants were briefed about SWOT and were helped with plotting SWOT tables and building individual strategies. After one month, second formative assessment was conducted. Outcomes of two assessments were compared. Students’ perception of utility of SWOT analysis was assessed by scoring on a 6 point likert scale. Results: 83 participants who consented to participate in the study and present for all 4 sessions conducted were enrolled. There was a significant improvement in post test scores from mean of 5 (1.02 SD) to 7 (0.4 SD). 98% of students scored a 3 or more on likert scale indicated a positive perception of utility of SWOT analysis based strategies in improving learning outcomes. Discussion: Educational research studies based on SWOT analysis has been used for situational analysis as well as to develop strategic countermeasures in medical education but not for leverage of learning outcomes. Conclusion: SWOT analysis for strategy building to improve learning outcomes of prescription communication in medical students is effective as well as perceived as an important tool by students.

1 Thessalonians 4:13 and grief management in Nigerian churches
Authors: Ademiluka Solomon O.
Published: January 2025

1 Thessalonians 4:13 indicates that the Thessalonian Christians were deeply grieved about the death of their loved ones because they were not sure of the status of the deceased in the supposedly imminent parousia. Paul admonishes them not to grieve like those who have no hope, a caution which is highly relevant in Nigeria where death causes harrowing grief for those bereaved. This article interrogated the extent to which the application of this text relieves grief for Nigerian Christians, as well as its attendant impact on the people’s culture. The article employs the historical-critical exegesis and the phenomenological approach. It found that in the traditional African setting, the grieving process involved the performance of certain rituals which Christianity has condemned as heathen, as they contradict the injunction in 1 Thessalonians 4:13. Such mourning practices have been substituted with Christian models. Still, unfortunately, apart from being ineffective in addressing grief, this pastoral approach has impacted negatively on the cultural heritage and identity of Nigerian Christians. Therefore, for Christian burial in Nigeria to be desirable and effective in addressing mourners’ grief, there is a need for it to accommodate traditional practices as much as possible.Contribution: The article contributes to the interaction of Christianity with African culture. It argues that, for a Christian burial to be effective in addressing grief in Nigeria, there is a need for interaction with traditional mourning practices.

Authors: Smit Carla A. , Marais Belinda S.
Published: January 2025

Background: Good mental health literacy (MHL) has proven to aid in providing adequate and timely care, promote positive attitudes towards mental health and assist in the integration of mental healthcare with other services. Studies have shown that enhancing the MHL of healthcare workers (HCWs) can help alleviate the burden of mental illness.Aim: The study aims to explore the MHL of HCWs at a tertiary hospital in Johannesburg.Setting: The study was conducted at Helen Joseph Hospital.Methods: A quantitative, descriptive, cross-sectional study via a self-administered questionnaire consisting of: (1) a demographic, work and exposure to mental illness and mental healthcare services questionnaire and (2) the Mental Health Literacy Scale (MHLS) was employed. The MHLS identifies people with low MHL who could benefit from further interventions.Results: Two hundred and fifty-two HCWs participated in the study. The overall median MHLS score was 129, in keeping with a previous study conducted in SA and Zambia. Younger HCWs with less than 5 years of experience scored higher. Among the various professions, doctors scored highest and nurses lowest. The anaesthetic and psychiatric departments obtained the highest MHLS scores. Personal exposure to mental illness and mental health services was associated with higher MHLS scores.Conclusion: This study highlighted areas where mental health awareness and education are lacking, which are crucial for improving MHL. Targeted interventions to fill these identified gaps are therefore recommended.Contribution: To our knowledge, this was the first South African study to assess MHL among tertiary-level HCWs across various professions.

Published: January 2025

Introduction:

Globally, in the age group of 5–17 years, about 10% of schoolchildren are overweight or obese. According to an Indian study among 12–16-year-olds, the overall prevalence of overweight and obesity was 10.8% and 6.2%, respectively. Childhood and adolescent obesity may lead to emotional and behavioral problems, poor socialization, and stigmatization. With this study, we aimed to describe the emotional and behavioral patterns in overweight and obese school-going adolescents.

Materials and Methods:

Overweight and obese schoolchildren between 10 and 15 years of age were included and administered the self-reported version of the Strengths and Difficulties Questionnaire (SDQ). Behavioral patterns across emotional, conduct, hyperactivity, peer relationship problems, and pro-social behavior were assessed, and a “total difficulty score” was noted.

Results:

Out of 260 overweight and obese children included in our study, 131 (50%) were males, 129 (50%) were females, 85 (33%) were overweight, and 175 (67%) were obese. The SDQ showed an abnormal score in about 19% of children with respect to the emotional component, 22% of children in the category of conduct problems, 3% and 9% of children, respectively, in hyperactivity and peer relationship problems, and 9% of children with respect to pro-social behavior patterns; however, these were not statistically significant. Around 13% of the children in our study had an abnormal “total difficulty score” on the SDQ; however, this was not statistically significant (P = 0.47). The proportion of abnormal scores was higher among obese children than the overweight ones in our study, though statistically not significant.

Conclusions:

Overweight and obese children have a high likelihood of developing behavioral problems. Understanding this association may help in the development of comprehensive programs and interventions to promote physical and mental well-being in adolescents.

Published: January 2025

Introduction:

Imposter syndrome has increasingly become a subject of concern in the mental health of medical students. It is very problematic as it can lead to high levels of stress and burnout among them. This study aimed in determining the magnitude of imposter syndrome among medical students in a medical college of West Bengal and its associates.

Materials and Methods:

This cross-sectional study was conducted among 104 undergraduate medical students in a medical college of West Bengal. Imposter syndrome was assessed using the Harvey Imposter Phenomenon Scale (HIPS). Perceived stress and coping ability were also assessed using a predesigned validated questionnaire. Data were analyzed using SPSS software. Pearson correlation test was done to find the relationship between imposter syndrome with perceived stress and coping ability.

Results:

The median age of study participants was 22 years (interquartile range = 21–23); 48.1% were males. The mean HIPS score was 34.96 ± 8.97, and 19.2% (n = 20) had significant imposter feelings. Imposter scores showed a significant weak positive correlation with perceived stress scores (r = 0.37, P < 0.001) while coping ability showed a protective effect against imposter syndrome (r =−0.301, P = 0.002).

Conclusion:

Awareness campaigns at the various medical institutions along with face-to-face counseling with trained psychologists for those with symptoms suggestive of imposter syndrome will help in improving the mental well-being of medical students.
Hidden challenges to happiness: A cross-sectional study of Western Maharashtra, India
Authors: Gore Alka Dilip , Dhobale Randhir V. , Waghachavare Vivek B. , Dhumale Girish B.
Published: January 2025

Background and Objectives:

Individual happiness and well-being are the most essential components of quality of life. For the last few years, the United Nations General Assembly has annually published the World Happiness Report, and the ranking of India has repeatedly fallen to an alarming level where the country’s position remains below 100 nations in these surveys. Hence, this study was carried out to uncover the associated sociodemographic and lifestyle-related factors for happiness and well-being in the general population of Sangli district, Western Maharashtra, India.

Materials and Methods:

A cross-sectional study was conducted using a questionnaire among willing adults in the Sangli district. Section A regarding the sociodemographic data; Section B is the evaluation of lifestyle-related factors; and Section C contains a 29-item Oxford Happiness Questionnaire scale for assessing personal happiness. Microsoft Office 365 and SPSS-22 software were used to analyze data.

Results:

Out of the 679 participants, 61.9% of 420 people were not happy or somewhat unhappy, 34% were satisfied, and only 4.1% were happy. Participants were significantly unhappy despite having reliable and trustworthy friends and even after taking a complete rest.

Multivariate analysis showed age, per capita income, occupation, and education are significant predictors of the happiness index score.

Interpretation and Conclusion:

People did not experience happiness after several favorable situations. Happiness is complex and subjective; it is very challenging to capture fully with a single index or questionnaire.
