Authors: Adi Susilo , Setyawan Rachmat , Sumarlin Tantik
Published: January 2025

This study examines the effect of personalization-based digital marketing strategies on brand loyalty within cross-cultural contexts, employing A/B testing and multivariate analysis methods. The research is motivated by the critical role of digital marketing in fostering consumer relationships and the challenges of understanding cultural differences that influence consumer responses to marketing strategies. The primary objective of the study is to analyze how cultural dimensions moderate the effectiveness of personalized marketing content in enhancing brand loyalty. The study was conducted through an experiment involving 200 participants divided into two groups: one group received personalized digital content, while the other received standard content. Multivariate Analysis of Variance (MANOVA) was used to evaluate the effects of culture and marketing strategies on brand loyalty, consumer satisfaction, and product recommendations. The results indicate that personalized content significantly increases brand loyalty (M = 4.5, SD = 0.8) compared to standard content (M = 3.8, SD = 1.0; p < 0.05). Additionally, consumers from collectivist cultures demonstrated a more positive response to personalized content, with higher brand loyalty scores (M = 4.6) compared to those from individualist cultures (M = 4.0). This study underscores the importance of cultural sensitivity in digital marketing strategy planning. Integrating personalization elements with an understanding of cultural contexts has been shown to enhance consumer engagement and foster stronger brand loyalty. These results provide both empirical contributions and practical guidance for companies in designing effective marketing campaigns for diverse global markets.

Published: January 2025

Corporate governance is crucial in enhancing competitiveness and attracting investment, particularly in emerging markets that face challenges such as complex regulatory environments and ownership structures. Shareholder activism has emerged as an essential mechanism for improving corporate accountability and performance. This study aims to analyze the impact of shareholder activism on corporate performance in emerging markets, considering corporate governance as a moderating variable. A quantitative approach is employed, utilizing panel data analysis from publicly listed companies in emerging markets over a period of 5 to 10 years. Corporate performance is measured using financial indicators such as Return on Assets (ROA), Return on Equity (ROE), and Tobin's Q, while shareholder activism is assessed based on the number of resolutions proposed in shareholder meetings. A panel regression model is applied to identify the relationships among the variables. The results indicate that shareholder activism has a significant positive impact on corporate performance, with a coefficient of 0.35 for ROA (p-value 0.001). Corporate governance acts as a moderator that strengthens this relationship, with an interaction coefficient of 0.10 (p-value 0.05). Overall, the regression model explains 78% of the variation in corporate performance (R-squared = 0.78). This study provides empirical evidence demonstrating that shareholder activism, supported by robust governance, can enhance corporate transparency and accountability in emerging markets. These findings are relevant for stakeholders aiming to promote better governance practices to sustainably enhance corporate competitiveness

Published: January 2025

Capital markets play a strategic role in the global economy; however, high volatility often poses challenges for investors in making optimal investment decisions. Stock price prediction has become one of the key elements in effective portfolio management, but the complexity of market data demands more advanced analytical approaches. This study aims to explore the potential of Long Short-Term Memory (LSTM) models in predicting stock price movements and integrating these predictions into portfolio optimization strategies based on modern portfolio theory. The research methodology utilizes historical stock data from the S&P 500 and IDX Composite indices with daily frequency. The LSTM model is compared with Recurrent Neural Networks (RNN), Support Vector Machines (SVM), and Artificial Neural Networks (ANN) using metrics such as Mean Squared Error (MSE), Root Mean Squared Error (RMSE), and accuracy. The LSTM model demonstrated superior performance with an MSE of 0.0018, RMSE of 0.042, and prediction accuracy of 91.5%, significantly outperforming RNN (87.3%), SVM (80.2%), and ANN (82.7%). The prediction results were then integrated into portfolio optimization using the Mean-Variance Optimization approach, resulting in an increase in expected returns from 8.5% to 12.3%, a reduction in risk from 6.2% to 5.8%, and an improvement in the Sharpe ratio from 1.37 to 2.12. This study demonstrates that the LSTM model not only excels in stock price prediction accuracy but also contributes significantly to enhancing portfolio management efficiency. This Deep Learning-based approach offers a more adaptive, data-driven investment strategy, supporting more informed decision-making in the dynamic capital market

Published: January 2025

Employee engagement is a crucial factor in organizational success, particularly in the dynamic and competitive technology sector. Traditional approaches, such as financial incentives, often fail to create sustainable intrinsic motivation, necessitating innovative solutions such as gamification. This study aims to analyze the role of gamification in enhancing employee engagement through the implementation of digital platforms in medium-sized technology companies. The research employs a case study methodology with a qualitative approach, involving in-depth interviews with 15 informants, including employees and managers, as well as user activity data analysis from the gamification platform. The findings indicate that gamification significantly improved employee engagement, with the proportion of employees exhibiting "High" engagement levels increasing from 25% to 60%, and "Very High" levels rising from 10% to 35%. Conversely, the "Very Low" category decreased from 15% to 5%. These results suggest that gamification elements such as rewards, challenges, and team collaboration fulfill employees’ psychological needs and create a more dynamic and productive work environment. This study contributes to the literature by providing insights into the effectiveness of gamification in the technology sector and offering practical recommendations for organizations to design relevant and sustainable gamification platforms. In conclusion, gamification is a promising strategy for enhancing employee engagement, provided that its elements are tailored to individual preferences and the technological readiness of the organization

Published: January 2025

Abstract. Reports on the composition of ultrafine particles (<100 nm in diameter) in the Amazon are scarce, due in part to the fact that new-particle formation has rarely been observed near ground level. Ultrafine particles near the surface have nevertheless been observed, leaving open questions regarding the sources and chemistry of their formation and growth, particularly as these vary across seasons. Here, we present measurements of the composition of ultrafine particles collected in the Tapajós National Forest (2.857° S, 54.959° W) during three different seasonal periods: 10–30 September 2016 (SEP), 18 November–23 December 2016 (DEC), and 22 May–21 June 2017 (JUN). Size-selected (5–70 nm) particles were collected daily (for 22 h each day) using an offline sampler. Samples collected during the three time periods were compiled and analyzed using liquid chromatography coupled with Orbitrap high-resolution mass spectrometry. Our findings suggest a sustained influence of isoprene organosulfate chemistry on ultrafine particles from the different periods. We present chemical evidence that indicates that biological-spore fragmentation impacted ultrafine-particle composition during the late wet season (JUN), while chemical markers for biomass burning and secondary chemistry peaked during the dry season (SEP and DEC). Higher oxidation states and degrees of unsaturation were observed for organics in the dry season (SEP and DEC), suggesting greater extents of aerosol aging. Finally, applying a volatility parameterization to the observed compounds suggests that organic sulfur species are likely key drivers of new-particle growth in the region due to their low volatility compared to other species.

Abstract. Climate variability in the last millennium (past 1000 years) is dominated by the effects of large-magnitude volcanic eruptions; however, a long-standing mismatch exists between model-simulated and tree-ring-derived surface cooling. Accounting for the self-limiting effects of large sulfur dioxide (SO2) injections and the limitations in tree-ring records, such as lagged responses due to biological memory, reconciles some of the discrepancy, but uncertainties remain, particularly for the largest tropical eruptions. The representation of volcanic forcing in the latest generation of climate models has improved significantly, but most models prescribe the aerosol optical properties rather than using SO2 emissions directly and including interactions between the aerosol, chemistry, and dynamics. Here, we use the UK Earth System Model (UKESM) to simulate the climate of the last millennium (1250–1850 CE) using volcanic SO2 emissions. Averaged across all large-magnitude eruptions, we find similar Northern Hemisphere (NH) summer cooling compared with other last-millennium climate simulations from the Paleoclimate Modelling Intercomparison Project Phase 4 (PMIP4), run with both SO2 emissions and prescribed forcing, and a continued overestimation of surface cooling compared with tree-ring reconstructions. However, for the largest-magnitude tropical eruptions in 1257 (Mt. Samalas) and 1815 (Mt. Tambora), some models, including UKESM1, suggest a smaller NH summer cooling that is in better agreement with tree-ring records. In UKESM1, we find that the simulated volcanic forcing differs considerably from the PMIP4 dataset used in models without interactive aerosol schemes, with marked differences in the hemispheric spread of the aerosol, resulting in lower forcing in the NH when SO2 emissions are used. Our results suggest that, for the largest tropical eruptions, the spatial distribution of aerosol can account for some of the discrepancies between model-simulated and tree-ring-derived cooling. Further work should therefore focus on better resolving the spatial distribution of aerosol forcing for past eruptions.
Timberline formation and relationship with climatic variables of Indian central Himalaya: role of topography
Authors: Sah Priyanka , Sharma Subrat , Shaik Rehana
Published: January 2025

Abstract. The young and rapidly rising Himalayas, with their diverse landscapes and ecosystems, are highly vulnerable to climate change impacts. This study explores relationship between spatially different timberline altitudes and geological regions of the Indian Himalayan region. First time, geological and topographical influence of mountainous terrain on formation of high-altitude timberline in the Indian Central Himalaya has been described. Total 2,750 km of timberline was mapped using Landsat 8 (30 m) satellite images. Timberline occurs between 2600 m and 4365 m amsl altitude in the Indian Central Himalayan region but predominance (~75 %) was between 3200 m and 3800 m amsl. Geologically different regions have different representations of timberline altitudes. Maximum occurrence was in the Greater Himalaya (77 % of the total timberline, mean timberline altitude 3599 m asl) followed by the Lesser Himalaya (17 %, mean altitude 3424 m asl) and Trans Himalaya (6.3 %, mean altitude 3723 m asl). Timberline around summits which is far away from permanent snowline was not present in the Trans Himalaya, and was mostly present in the Lesser Himalaya (between two major geological faults). It was observed that occurrence of geological faults created habitats in greater number of Island Type Timberline (ITL), and also brought higher segmentation in Continuous Type Timberline (CTL). The average annual temperature was 9.9 °C ± 3.41, ranging from 1.0 °C to 18.3 °C, with average annual rainfall of 1049 ± 183 mm, varying between 609 mm and 1448 mm. CTL areas had high rainfall peaks in July (275 mm) and August (269 mm), with lower winter levels, while ITL areas experienced consistently higher rainfall year-round, peaking in July (325 mm) and August (255 mm). CTL temperatures dropped significantly with elevation, from 3.7 °C in January to below -5.5 °C, whereas ITL temperatures remained milder and more stable, ranging from 1.4 °C to 5.16 °C. In the high ranges of Indian Central Himalaya, geological disturbances accounted for the segmentation in continuity and created habitats for isolated timberlines. These observations indicate that geological factors have a considerable role in giving shape to continuation of high elevation forests and upper limits of timberline. At local scale topography is an obvious way to size up the landscape and influencing distribution of high-altitude tree species.
age_flow_line-1.0: a fast and accurate numerical age model for a pseudo-steady flow tube of an ice sheet
Authors: Parrenin Frédéric , Chung Ailsa , Martín Carlos
Published: January 2025

Abstract. Numerical age models are useful tools for investigating the age of the ice in an ice sheet. They can be used to date ice cores or to interpret isochronal horizons which are observed by radar instruments. Here, we present a new numerical age model for a flow line of an ice sheet. The assumption here is that the geometry of the flow line and the velocity shape functions are steady (i.e. constant in time). A time-varying factor can only be applied to the surface accumulation rates and basal melting rates. Our model uses an innovative coordinate system (𝜋,𝜃), previously published, which is suitable for solving transport equations. Using this coordinate system, solving the age equation is simple, fast and accurate, because the trajectories of ice particles pass exactly through the nodes of the grid. Our numerical scheme, called Eulerian-Lagrangian, therefore combines the advantages of Eulerian and Lagrangian schemes. We present an application of this model to the flow line going from Dome C to Little Dome C and show that horizontal flow is a non-negligible factor which should be considered when modelling the age-depth relationship of the Beyond EPICA ice core. The code we developed for age modelling along a flow tube is named age_flow_line-1.0 and is freely available under an open-source license.
ML-AMPSIT: Machine Learning-based Automated Multi-method Parameter Sensitivity and Importance analysis Tool
Authors: Di Santo Dario , He Cenlin , Chen Fei , Giovannini Lorenzo
Published: January 2025

Abstract. The accurate calibration of parameters in atmospheric and Earth system models is crucial for improving their performance but remains a challenge due to their inherent complexity, which is reflected in input–output relationships often characterised by multiple interactions between the parameters, thus hindering the use of simple sensitivity analysis methods. This paper introduces the Machine Learning-based Automated Multi-method Parameter Sensitivity and Importance analysis Tool (ML-AMPSIT), a new tool designed with the aim of providing a simple and flexible framework to estimate the sensitivity and importance of parameters in complex numerical weather prediction models. This tool leverages the strengths of multiple regression-based and probabilistic machine learning methods, including LASSO (see the list of abbreviations in Appendix B), support vector machine, classification and regression trees, random forest, extreme gradient boosting, Gaussian process regression, and Bayesian ridge regression. These regression algorithms are used to construct computationally inexpensive surrogate models to effectively predict the impact of input parameter variations on model output, thereby significantly reducing the computational burden of running high-fidelity models for sensitivity analysis. Moreover, the multi-method approach allows for a comparative analysis of the results. Through a detailed case study with the Weather Research and Forecasting (WRF) model coupled with the Noah-MP land surface model, ML-AMPSIT is demonstrated to efficiently predict the effects of varying the values of Noah-MP model parameters with a relatively small number of model runs by simulating a sea breeze circulation over an idealised flat domain. This paper points out how ML-AMPSIT can be an efficient tool for performing sensitivity and importance analysis for complex models, guiding the user through the different steps and allowing for a simplification and automatisation of the process.

Published: January 2025

Abstract. We present the very-high-resolution (VHR) version of the EC-Earth global climate model, EC-Earth3P-VHR, developed for HighResMIP. The model features an atmospheric resolution of ∼16 km and an oceanic resolution of 1/12° (∼8 km), which makes it one of the finest combined resolutions ever used to complete historical and scenario-like CMIP6 simulations. To evaluate the influence of numerical resolution on the simulated climate, EC-Earth3P-VHR is compared with two configurations of the same model at lower resolution: the ∼100 km grid EC-Earth3P-LR (LR) and the ∼25 km grid EC-Earth3P-HR (HR). Of the three configurations, VHR shows the smallest drift in the global mean ocean temperature and salinity at the end of a 100-year 1950s control simulation, which points to a faster equilibrating phase than in LR and HR. In terms of model biases, we compare the historical simulations against observations over the period 1980–2014. In contrast to LR and HR, VHR shows a reduced equatorial Pacific cold tongue bias, an improved Gulf Stream representation with a reduced coastal warm bias and a reduced subpolar North Atlantic cold bias, and more realistic orographic precipitation over mountain ranges. By contrast, VHR shows a larger warm bias and overly low sea ice extent over the Southern Ocean. Such biases in surface temperature have an impact on the atmospheric circulation aloft, connected with a more realistic storm track over the North Atlantic yet a less realistic storm track over the Southern Ocean compared to the lower-resolution model versions. Other biases persist or worsen with increased resolution from LR to VHR, such as the warm bias over the tropical upwelling region and the associated cloud cover underestimation, a precipitation excess over the tropical South Atlantic and North Pacific, and overly thick sea ice and an excess in oceanic mixing in the Arctic. VHR shows improved air–sea coupling over the tropical region, although it tends to overestimate the oceanic influence on the atmospheric variability at midlatitudes compared to observations and LR and HR. Together, these results highlight the potential for improved simulated climate in key regions, such as the Gulf Stream and the Equator, when the atmospheric and oceanic resolutions are finer than 25 km in both the ocean and atmosphere. Thanks to its unprecedented resolution, EC-Earth3P-VHR offers a new opportunity to study climate variability and change of such areas on regional and local spatial scales, in line with regional climate models.

Published: January 2025

Abstract. The Norwegian Government aims to install offshore wind power with a total capacity of 30 GW by 2040, and the Norwegian Water Resources and Energy Directorate has suggested 20 candidate regions. We show that the potential for reducing overall power production variance across these regions is high using modern portfolio theory and the hourly and spatially rich reanalysis NORA3 Wind Power data set (NORA3-WP). The geographical diversification effect is demonstrated under various relevant scenarios, including a sequential build-out scenario with a fully connected Norwegian power grid assumption. By considering 20 alternative regions selected using a recently developed suitability score, we further illustrate that the diversification effect is robust to location changes.

Published: January 2025

This study focuses on the study of the use of technology within the scope of the importance and objectives of preschool education in educational management. Preschool education allows the child to be more productive and creative at the same time while addressing all areas of development and to reveal his/her own potential at a high rate. During the preschool period, when preparation for life is made, children are able to reveal their identity in society by acquiring certain habits and developing individually. During this period, the physical environment consisting of rich stimulants contributes to the completion of the educational process in a good way by supporting the child's learning life and all areas of development. The preschool period, which is characterized as the first six years of life, covers the most active years when the child shows the fastest development and interacts with society. During these years, when brain development is progressing rapidly, the interaction and stimulants established with the social environment support the child's multifaceted development. All warnings received have an impact on the child's mental health and thinking skills. When the child's brain development and mental health are evaluated as a whole, the importance of environmental factors will be better understood and it will be serious for the child to complete his development in a healthy environment. Within this scope, technology, which covers every area of life, reaches every audience starting from preschool by enabling children to get acquainted with technological devices at a young age. With the widespread use of technological devices, various academic debates have also emerged about the dimension that children add to their lives. As a result of these discussions, it has been reached that technology poses a risk in child development. The reason is stated as the fact that the touch screen takes over the child's life and he faces various diseases while distancing himself from society. Like the technological activities that have increased recently, the time that children devote to technology is also increasing at the same rate. Although many researchers and educators have advocated the importance of children learning with technology since preschool and have devoted themselves to researching and implementing technology-related applications, the impact of young children's technology use on their development still needs to be discussed. Therefore, it is necessary to provide a typology in order to Deconstruct the interaction between technology and critical factors affecting children's learning in an effective way.

Published: January 2025

Os movimentos sociais têm origens muito antigas; contudo, a internet modificou o modo como os cidadãos se manifestam por mudanças, potencializando a indignação coletiva a um nível global e inserindo um novo tipo de ativismo: o digital. Essas manifestações online abordam os mais diversos temas, e uma das questões mais recentes que apareceram nas redes sociais, inserida no movimento ambiental, é a manifestação pelos canudos sustentáveis. Contudo, qual o impacto jurídico-legislativo gerado pelos ativismos digitais em busca da utilização de canudos biodegradáveis? Para responder ao problema de pesquisa, são utilizados o método dedutivo para a abordagem e os métodos monográfico e estatístico para o procedimento, a partir de revisão bibliográfica e documental. O primeiro capítulo é responsável por abordar os ativismos digitais e os novíssimos movimentos sociais, bem como o movimento ambiental, enquanto o segundo capítulo reduz o estudo para a questão das manifestações pelos canudos biodegradáveis e o impacto jurídico-legislativo causado na realidade brasileira. Dessa forma, é possível concluir que o ativismo digital pelos canudos biodegradáveis gerou efeitos positivos a níveis de legislação no Brasil tendo em vista que, dos 23 estados da federação analisados, todos já possuem cidades com proibição da venda de canudos plásticos e 7 deles já contam com legislação proibitiva em todo o território. Essa onda de coibição do uso de canudos plásticos gerou um movimento de conscientização a nível nacional, que fez emergir discussões sobre outros produtos que causam danos ao meio ambiente.

Published: January 2025

Este texto discute os impactos da Lei 13.465/17, que inseriu o Art. 40-A na Lei 11.952/09, nos projetos de colonização na Amazônia. Analisou-se a incompatibilidade do modelo normativo dos núcleos de colonização, criados antes da Constituição de 1988, e o contexto socioambiental, num estudo de caso: o Projeto de Assentamento Rio Juma, em Apuí, Amazonas. Os impactos da lei foram projetados nos eixos ambiental, socioeconômico, normativo e administrativo. O PA Juma tem avanços, mas o modelo ficou desgastado. Há vantagens em se descaracterizar o assentamento, em vez de emancipá-lo. O regulamento do Art. 40-A deve levar em conta as relações jurídicas entre União e assentados durante estes anos. Espera-se uma melhora no plano socioeconômico, contudo, no plano da governança ambiental, mas o sucesso dependerá de salvaguardas como o fortalecimento do órgão fundiário. Por fim, a aplicação da norma trará uma alteração substancial na administração pública fundiária e na política local.

Origin of proximal femur fracture classification and their namegivers
Authors: SCHMITZ P.P. , VAN SUSANTE J.L.C. , SOMFORD M.P.
Published: January 2025

Due to the high incidence of proximal femoral fractures, classifications of these fractures are often used in daily practice. Most classifications are eponymous terms since they bear the name of the person(s) who developed them. In this study we provide an insight in the origin of the classifications and the background of their name givers. The clinical implication and background of the eponymous proximal femur fracture classifications of Garden, Pauwels and Evans-Jensen are discussed.

With the rising use of modern classification systems, the relevance of historically important classifications is food for discussion. Nevertheless, these classification systems are still used in daily communication and decision making.

Metastasis stands as one of the most prominent prognostic factors in osteosarcoma. Over 70% of metastatic osteosarcoma occurrences affect the lung. Nonetheless, to date, there has been a scarcity of research addressing predictive factors for lung metastasis risk in osteosarcoma. The objective of this study is to identify the predictive factors that have a role in the risk of lung metastasis in osteosarcoma. This is a retrospective study conducted between January 2018 until January 2023. From the obtained research subjects, an assessment selection was carried out using inclusion and exclusion criteria. Subsequently, preoperative data related to predictive factors will be collected from the research subjects, followed by a clinicopathological conference, chemotherapy, and surgery. Afterward, an evaluation of pulmonary metastasis will be conducted six months after the diagnosis. A total of 47 osteosarcoma patients who met the inclusion and exclusion criteria were analyzed. Bivariate and multivariate logistic regression analyses revealed statistically significant predictive factors for the risk of pulmonary metastasis in osteosarcoma: ALP levels (p=0.014), LDH levels (p=0.038), presence of pathological fractures (p=0.025), and tumor size (p=0.027).

Brucellosis, caused by a facultative intracellular gram-negative coccobacillus, is one of the most common zoonotic infections worldwide. Very rarely, brucellosis can cause periprosthetic joint infections (PJI). In this case-based literature review, we summarize the current medical literature regarding Brucella PJI, with the aim to raise awareness among clinicians, particularly in non-endemic areas. We report a case of a woman with a 3 weeks history of increasing hip pain, who was eventually diagnosed with Brucella PJI. We searched multiple databases to identify all case reports on Brucella PJI in humans published from February, 1983 to December, 2023. A total of 42 cases from 38 published articles were retrieved and summarized, along with our case. Mean age was 65.5 years, with sex ratio nearly one. Almost all patients presented with local symptoms and 56% with systemic symptoms. Only knee (n=30) and hip (n=13) prosthetic joint were involved. If performed, culture showed positive results on synovial fluid (74%), intra- operative tissue (79%), and/or blood (38%). Serological confirmation was obtained in 97%. Antimicrobial treatment consisted of a combination of doxycycline and rifampin in most cases, with in nearly half of the cases the addition of an aminoglycoside. The majority of patients (n=24) were surgically treated with a two stage exchange arthroplasty; although other options were successful as well. Brucella PJI is a rare but potentially severe manifestation of brucellosis. Brucella PJI must be considered in patients from endemic areas, especially when another causative agent has not been isolated. If culture results remain negative, PCR or serology should be performed. To date, there is no uniform recommendation for the duration of antimicrobial therapy nor the preferred surgical procedure. Relapse is possible even with adequate therapy.

Authors: Syeedul Al-Amin, Abu Khaled Rony
Published: January 2025

The main objective of this research was to identify the critical role of Occupational Health and Safety (OHS) practices in driving organizational productivity, with focusing on Abdul Monem Ltd. Beverage Unit (AMLBU), a Coca-Cola manufacturing plant in Cumilla,, Bangladesh. Established in 1986, the plant operates across four production lines, producing a range of carbonated and non-carbonated beverages. With a workforce of over 800 employees, including permanent, daily, and sales staff, the facility faces unique OHS challenges common to beverage manufacturing, such as handling hazardous materials, operating heavy machinery, and managing ergonomic risks.
The research methodology integrates both qualitative and quantitative approaches combining random and judgmental sampling techniques to analyze 100 observations, representing both diverse and critical incidents. Data were collected through direct observation, surveys, and reviews of internal documents, such as safety reports and manuals, supplemented by relevant industry publications.Findings reveal a strong correlation between effective OHS practices and enhanced productivity. Key measures, such as ergonomic interventions, compliance with safety protocols, and the use of Personal Protective Equipment (PPE), significantly reduce workplace accidents and absenteeism while fostering employee efficiency and well-being.
Key findings reveal effective OHS programs—such as ergonomic interventions, rigorous safety protocols, and the provision of Personal Protective Equipment (PPE)—significantly enhance productivity by reducing workplace accidents, absenteeism, and operational disruptions. This research also finds out a strong correlation between effective OHS measures and enhanced organizational performance. Employees working in environments that prioritize safety and health demonstrate higher morale, reduced absenteeism, and increased productivity. Conversely, unsafe practices and inadequate safety protocols often lead to accidents, injuries, and diminished workforce efficiency.
This research contributes to the growing discourse on the economic and social benefits of OHS programs, offering valuable insights for industry leaders, policymakers, and academics. It advocates for a paradigm shift where workplace safety is viewed not merely as a regulatory requirement but as a strategic investment in organizational success.This study serves as a reference for future research and decision-making in the beverage manufacturing sector and beyond.

PISTES POUR UNE DIDACTIQUE EN OLFACTION/WONDERINGS IN OLFACTION DIDACTICS
Authors:   UCO Niort, France, Sandra CADIOU
Published: January 2025

Olfaction is an unloved and poorly known sense, yet it brings pleasure, emotions, and memories. Schools train future professionals, for example, in fine or laundry perfumery. The olfaction course is fundamental: you learn to (re) know smells, which is the basis of the professional's work. How is it taught? Through the case of a teacher in charge of this course, we wish to answer this question to more broadly develop milestones for research in olfaction didactics.

The article highlights the increasing focus on clarifying the concept of pedagogical action research (PAR) and its critical role in the professional development of educators. It emphasizes the importance of designing and conducting PAR to cultivate investigative competence and foster innovation within educational settings. By refining the theoretical framework of PAR, the article lays the groundwork for advancing contemporary pedagogical thinking, with an emphasis on integrating innovative practices into education to enhance efficiency and effectiveness. The Theoretical Model of Pedagogical Action Research, developed as part of this work, addresses the gaps in existing definitions and models by emphasizing the specificity of PAR. It outlines a framework for the cyclical development of competences such as conceptualizing research, strategic management, critical reflection, educational innovation, re-planning of pedagogical action research etc. This Model provides a structured approach to conducting PAR while advancing educators’ abilities to adapt to dynamic teaching environments. Additionally, the paper underscores the benefits of PAR for teachers, including improved problem-solving skills, renewed teaching strategies, and enhanced self-reflection. These qualities contribute to continuous professional growth and resilience in addressing challenges in teaching. Furthermore, PAR equips teachers to respond effectively to contemporary educational demands, such as integrating students with special needs, managing cultural diversity, and aligning with evolving labor market requirements. In the context of globalized education, PAR fosters educators’ preparedness to guide students in navigating an interconnected world. By integrating PAR practices, teachers not only enhance their professional competences but also strengthen their capacity to drive educational innovation, ensuring their relevance and impact in a rapidly changing educational landscape.

Authors:   University Ibn Khaldoun of Tiaret, Algeria, Naoual AOUALI
Published: January 2025

Distance assessment in higher education represents a significant advancement, providing a relevant alternative to traditional in-person evaluation methods. To ensure the success of this approach, it is essential to consider students' perceptions, which play a crucial role in the acceptance and effectiveness of this mode of assessment.
Our research aims to explore in depth the representations of students regarding distance assessment, analysing their understanding through the lens of their lived experiences. To achieve this, we developed a questionnaire survey targeting a diverse sample of university students. This methodology allowed us to collect both qualitative and quantitative data, offering a nuanced view of students' attitudes and perceptions.
The analysis of the results highlighted the various ways in which students experience and interpret distance assessment. By revealing their ideas, concerns, and challenges, we hope to make a significant contribution to improving the implementation of this approach.

Streamlining learning has always been an important concern of psychologists, education specialists, both theorists and practitioners. The acquisition of autonomy in learning is the clearest proof of the formation of an effective learning style, which ensures and determines a deep, sustainable learning. One of the ways that can be leveraged to achieve autonomy and flexibility is problem-solving.
The present study aims to analyze the role of this learning modality in the development of autonomy, to identify ways, strategies, concrete techniques of realization, all this – from the perspective of some students-future teachers.
The sample of subjects consisted of 74 second-year master's students from the Faculty of Letters, who are also attending the Initial Professionalization Program, level II, this being a level of deepening, of developing the skills previously formed, by going through the same program, level I. We considered this sample considering the specificity of their training (psycho-pedagogical, methodical, practical), but also their role as future trainers.
The research methods used were the questionnaire-based survey and the focus-pit, the tools applied being a questionnaire and an interview guide.
The results recorded, cumulative, following the application of the two research methods, allowed the formulation of conclusions regarding the importance of autonomy and flexibility in learning, respectively the role of problem-based learning in achieving this objective.
