A Survey Paper on Plastic Solar Cell Technology
Authors: Langhe Shruti
Published: November 2024

The demand of energy is increasing day by day so non-conventional source of energy has to be used. Sun is the nonconventional source of energy. Conventional solar panels convert solar energy into electrical energy. A plastic solar cell is the type of photovoltaic that makes use of organic electronics dealing with conductive organic polymers or small molecules for light absorption and charge transport to produce electricity from sunlight by the photovoltaic effect. Polymers Provide the Advantage of Solution Processing at Room Temperature, which is Less Expensive and Enables One to Use Plastics. Therefore, If Silicon Is Replaced with Polymer Nanowires, The Solar Cell Would Be Much Lighter and Ultimately Less Costly. These Solar Cells are Thin, Several Microns in Diameter, and Scavenge All the Rays from the Sun's Radiation. Plastic Solar Cell Technology is Based on Conjugated Polymers and Molecules. Polymer Solar Cells have Generated Considerable Interest Since it Provides Environmentally Friendly, Flexible, Lightweight, Low Cost, Possibility of High-Efficiency Solar Cells in the Last Couple of Decades. Plastic Solar Cells are More Efficient and Viable in Usage. This dissertation focuses on the development and optimization of plastic solar cell technology, in particular this potential towards flexible, lightweight, and cost-effective alternative sources to traditional silicon-based solar cells. The focus of the present research work is to find optimum organic materials for higher efficiency and stability in plastic solar cells, varying from conjugated polymers to small organic molecules. Some of the main goals are improving the charge transport mechanisms and optimizing the architecture of devices through state-of-the-art techniques of fabrication, like roll-to-roll printing and layer-by-layer deposition. The other key aspect is that the project assesses the environmental aspects and lifecycle of plastic solar cells to ensure an environmentally friendly production process. Huge preliminary results were achieved at high power conversion efficiencies and durability has been greatly improved, targeting very wide spread application from portable electronics up to building-integrated photovoltaics. Therefore, the discovery of plastic solar cells might be a major step for applicable solutions in renewable energy and towards overcoming the world's increasing energy challenges.
Evaluating Brazilian Parenting: Evidence of Validity and Invariance for Fathers and Mothers
Authors: Santis Ligia , Porto Noronha Ana Paula
Published: November 2024

Historically, studies on parenting were mostly based on maternal reports, generating uncertainties about its conclusions. Inverting this logic, in Brazil, the Inventory of Father Involvement (originally developed in the USA to assess men) was improved and adapted for mothers, generating the Inventory of Father and Mother Involvement (IFMI). The IFMI’s content validity was verified, but its internal structure was still unknown. This study aimed to verify evidence of validity based on its internal structure, reliability estimates and the invariance of this structure for fathers and mothers. For this purpose, 1244 fathers and mothers from 22 Brazilian states (with children aged 2 to 10) answered the Sociodemographic Questionnaire and the IFMI. Exploratory (EFA; n = 621), confirmatory (CFA; n = 623) and multigroup confirmatory factor analysis (MGCFA) were performed, and reliability estimates were verified. EFA and CFA results indicated the existence of seven factors in a second-order hierarchical structure. Reliability estimates ranged from .635 ≤ ω ≥ .875. MGCFA results indicated the invariance of this structure for fathers and mothers. In addition to the evidence of validity, these results contribute to broadening theoretical understandings about Brazilian parenting, enabling future comparative studies. It is important to further verify additional validity evidence.
DEVIATIONS IN THE APPEARANCE OF THE COMMANDING STAFF OF THE RED ARMY (THE SECOND HALF OF THE 1920S)
Authors:   Orel State University (Russia), Abinyakin R.M.
Published: November 2024

The article examines the suicides of the commanding officers of the Red Army in the second half of the 1920s as a very specific and painful symptom of the breakdown of the old and the formation of a new society in general and the folding of its military-corporate structure in particular. This problem is one of the characteristic and poorly studied indicators of the social and moral characteristics and attitudes of military personnel in the conditions of post-war psychological trauma, radical social transformations, political struggle, new economic policy and the consequences of the "military reform of the USSR". The causes, motives and specifics of the official, material, everyday, value, emotional and even medical conditions of the Red Army servicemen have been identified, systematized and analyzed. Special attention is paid to the commanding staff, including former officers as bearers of military traditions and shortcomings of the old Russian army during the formation of continuity with the Red Army. His office and home psychological microclimate during the period under study was characterized by serious lability and deviations, which adversely affected both the purely military sphere and the general socio-political well-being. The bulk of the sources used are represented by archival documents, which are being introduced into scientific circulation for the first time.

Authors:   Primorsky State Agrarian-Technological University (Russia), Simonenko E.S.
Published: November 2024

The paper studies the Canadian government’s policy in the field of material support for volunteers who enlisted in the Canadian Expeditionary Forces and the Navy during the First World War. It limits the chronological scope of the work to the period of August 4, 1914 – August 29, 1917. On August 4, 1914 Canada's entry into the war, and on August 29, 1917 the universal conscription was introduced in the country. In fact, it limits the presentation of events to the spring of 1916, when the basics of material support for Canadian volunteers were finally settled. It traced the evolution of government policy in the field of assigning monetary allowances to persons who served in the Canadian Expeditionary Force and in the Navy. It paid particular attention to legislative measures for the material support of volunteers. In general, during the First World War, material support for volunteers of the Canadian Expeditionary Forces and Navy was an integral part of the social policy pursued by the dominion authorities. It represented a system of measures aimed at compensating these categories of the population for the restrictions and hardships of military service, and to some extent raised the prestige of military service in society. It also represented an important basis for maintaining the morale of the troops at a high level and instilled in them confidence that the state guaranteed material support for their lives and everyday life.
REPRESENTATION OF THE USSR REPATRIATES' LEGACY IN THE MUSEUMS OF THE STATE OF ISRAEL
Authors:   Ivanovo State University (Russia), Chernoperov V.L. , Anisimova A.P. ,   Ivanovo State University (Russia)
Published: November 2024

The article examines issues of representation of Soviet Jews in the museum space of the State of Israel. Sources of various types have been studied, indicating the coverage of this problem by the Museum of the Jewish People on the campus of Tel Aviv University and the amuta in Haifa “Let's Remember and Preserve” - the Documentation Centre of the Jewish National Movement in the Soviet Union. When developing the issue, methods of personal, activity, cultural and selective approaches were used. It is concluded that the representation of the community of immigrants from the USSR in the space of the museums studied does not correspond to the significance and contribution that this part of the population made to the birth, formation and development of the State of Israel. In addition, it was noted that the considered museum sites do not reveal the phenomenon of the “Soviet Jew,” which includes representatives of regions that differ in their way of life and mentality, and do not sufficiently solve the problem of building a reliable bridge between the older generation of Russian-speaking repatriates and their descendants born in Israel. The “Ma’alot” community, created in 2016 and setting the goal of its activities to open a Heritage Centre for the Jews of the USSR in Israel, can change the current situation. And although certain difficulties arose along the way of these plans (the COVID-19 epidemic, the peculiarities of the legislation of the State of Israel, the choice of location, the fighting in Gaza and their consequences), the structure of the Centre has already been created, its project has been drawn up, its pages are widely represented on the Internet, and employees - at scientific and public sites.

SCIENTIFIC RESEARCHES OF THE 18TH CENTURY: PRIORITIES AND PRACTICAL MEANING
Authors:   M. V. Lomonosov’s museum at MAE RAS, St. Petersburg, Russia, Lupanova Ye.M.
Published: November 2024

General works usually present the 18th century as the time of modern sciences development; the period when the turn from the mediaeval scholastics to the modern experimental sciences has already happened. This stereotype formed in the middle of the 20th century (especially German and Soviet). Basing on a number of publications of that period and modern researches the author of this article shows how much had the ideas of sciences values in the 18th century with traditions, which are so often regarded to be outmoded by that time: the understanding of God’s purpose, collecting wonders of the world and the proofs of His wisdom, monarch’s labour to realize His intentions. The 18th century was very far from the technocratic designations formed in the 20th century and factitiously transformed to some earlier periods of times. The encyclopedic epoch is characterized by the appearance of institutes, secularization and rationalization of mentality, rethinking the hierarchy of different science and the methods of applying mathematical and logical instruments, the attitudes to “liberal” and “mechanical” art. Academic recommendations on solving some practical tasks cold include not only rational advices but also penance and eager invocation. The processes of modern science formation were complicated, gradual and multivalued. New trends included gradual and partial rethinking of sciences’ “use”, “mechanical arts” relative advantage in status, appearance of new ways of mathematics and logical reasoning application; refocusing knowledge to secular, material and anthropocentric values; rationalization of sciences as the turn to resource-studies and improving the efficiency of usage with the means of state management; institutionalization (appearance of academies, new universities and expert societies).

Published: November 2024

The relevance of the topic is related to the need to determine Russia’s place in the modern educational space, taking into account the challenges that determine the current situation in the world. The statement of the problem and the scope of this article are determined by the need to understand the processes of transformation of the education system throughout the world and in Russia. The methodological basis of this study is an approach that combines a number of general scientific and special research methods, which made it possible to study the raised problem systematically and, as a result, present the author’s forecast for the development of the educational space. Currently, the scientific and educational space should not be considered in the categories of “openness”, “equality” and “accessibility”. This approach, which idealizes the modern scientific and educational space, is erroneous, since it does not provide a clear understanding of the meaning of competitive relations in the modern education system. The modern scientific and educational space is a hierarchical system of various educational spaces (global, regional, national), the development trend of which is regionalization, as a result of which the educational space is reformatted under the influence of the politicization of educational activities. Currently, Russia is becoming one of the centers of power in the global geopolitical space, which determines the attractiveness of the Russian educational system, contributing to the transformation of Russia into one of the leaders of the modern educational space.

In this paper, we define the mapping called (ψ, ϕ, ω)-weak contractions. We then use this definition to proof the existence of fixed point. The mapping we defined above is a modified mapping by Liu and Chai. We use the concept ω-distance to proof the fixed point theorem. Since every ω-distance is metric, then the resulting theorem also satisfy for every metric.
ANALYSIS OF UNEMPLOYED YOUTH IN INDONESIA BY PANEL DATA REGRESSION WITH MODERATING VARIABLE
Authors: Subanti Sri , Amanda Nabila Tri
Published: November 2024

Indonesia is entering the era of demographic bonus with the productive age dominating the population. Productive age is the main focus of the government in maximizing the demographic dividend, but Indonesia has the highest percentage of Not in employment, education or training (NEET) in Asia. NEET are people on 15 â 24 years old who do other activities outside of school, work or training. This study aims to analyze NEET in Indonesia using panel data with moderate regression analysis. The analysis of multiple linear regression is focused on the relationship between the independent and dependent variables without taking into other possible outcomes. By inserting a moderating variable, this study explores the relationship between the independent and dependent variables differently and aims to strengthen or weaken it. Under certain conditions, the relationship between the independent and dependent variables can be explained by the moderating variable. The research data used were obtained from the employment book and the website of BPS Indonesia, in the form of 34 cross section and 5 years time series data that tends to be stationary. The dependent variable is NEET with 5 independent variables including Human development index, the open unemployment rate, labor force participation rate, proportion of individuals who own phone, and proportion of informal employment. The moderating variable is the proportion of youth aged with ICT skills. The best model in regression analysis panel data is FEM with 4 significant independent variables and 92.75% of R-square. Moderating variable can moderates the relationship of NEET with its independent variables and increased the R-square to 94.19%.

Authors: Macalintal Nevine , Taube Shoshana , Jones Vinci , Muntean Cornelia
Published: November 2024

Rapunzel syndrome is a rare condition that typically occurs in young females with trichotillomania or trichophagia. The name “Rapunzel” was given due to the presence of trichobezoars extending from the stomach down to various parts of the gastrointestinal tract. In this case, we discuss a 6-year-old female patient with a large trichobezoar that was further complicated by the occurrence of gastric perforation. This case emphasizes not only the presentation of a rare pathology with a rare complication but also the importance of meticulous history taking and physical examination for the approach to an acute abdominal emergency in the pediatric emergency setting.
Impact of public investment governance on provinces’ economics growth: A spatial approach
Authors: Vu Hung Phuong , Lam Do Van , Nguyen Thi Xuan Thu
Published: November 2024

The objective of this study is to evaluate the impact of public investment on the economic growth of the province in Vietnam, with a focus on a spatial perspective to uncover its effects. Applying the quasi-maximum likelihood (quasi-ML) estimation method developed by Belotti et al. (2017) to balanced panel data and conducting various tests, we identified the spatial Durbin model (SDM) as the most appropriate spatial model for the studied data. The importance of public investment in local economic growth is highlighted by an empirical analysis of 63 Vietnamese provinces from 2010 to 2020. Notably, taking spatial interactions into account, the finding reveals the existence of spillover effects of economic growth and public investment, demonstrating the impact of economic growth and public investment from one province on the economic growth of adjacent provinces. We incorporate the impact of foreign direct investment (FDI) in the analysis to highlight the role of public investment in economic growth in the long run. While FDI also has positive impacts on regional growth and has direct effects on neighboring provinces’ growth, it also has an adverse impact in terms of (indirect) spillover effects.

Polityka rachunkowości jednostek gospodarczych w zakresie doboru modeli wyceny bilansowej inwestycji finansowych
Authors: Rówińska Małgorzata
Published: November 2024

W artykule przedstawiono istotę poszczególnych grup i kategorii inwestycji finansowych według polskich oraz międzynarodowych regulacji rachunkowości. Wskazano zasady wyceny właściwe określonym kategoriom (według wartości godziwej lub skorygowanej cenie nabycia). Modele wartości godziwej przewidują aktualizację składnika aktywów na każdy dzień bilansowy, doprowadzając jego wartość do poziomu wartości godziwej wyznaczonej na dzień bilansowy. Model wyceny według skorygowanej ceny nabycia uwzględnia konieczność dokonywania korekty wartości początkowej o oprocentowanie (odsetki o kapita- łu). Modele oparte na wartości godziwej w coraz szerszym zakresie stają się podstawowymi modelami wyceny bilansowej inwestycji finansowych. Rozszerzenie stosowania modeli wyceny wykorzystujących wartość godziwą wpływa niewątpliwie na kreowanie własnej polityki bilansowej podmiotu.
Wycena inwestycji
Authors: Antczak Joanna
Published: November 2024

Podmiot gospodarczy, który się nie rozwija zmniejsza swój udział w rynku. Aby dotrzymać kroku liderom i nie wypaść z rynku, musi on niejednokrotnie mierzyć się z trudnymi wyborami dotyczącymi zarówno bieżącej działalności, jak i działań długoterminowych, mających charakter inwestycji. Trudno odpowiedzieć w chwili podejmowania decyzji o inwestowaniu, czy decyzje te zapewnią efektywność działania, czy polepszą wizerunek firmy. Efekty decyzji inwestycyjnych uwidoczniają się dopiero w przyszłości. Wybór metody wyceny inwestycji jest bardzo ważny. Możliwość zastosowania różnych metod, takich jak: ceny nabycia pomniejszonej o odpisy z tytułu trwałej utraty wartości, według wartości godziwej czy skorygowanej ceny nabycia wyceny inwestycji, powoduje konieczność dokonania wyboru metody wyceny dla jej stosowania w sposób ciągły i wieloletni. Wybór metody wyceny inwestycji musi być określony w stosowanej polityce rachunkowości danego podmiotu gospodarczego.

This paper presents content related to international expansion, which is valid and important both from the point of view of the enterprise, as well as national and global economy. One of the forms of activity in foreign markets are international mergers and acquisitions. Transactions of this type of host on the world markets for a long time, and its characteristic is that their intensity is once more, and less in another time. The phenomenon of cycling between low and then increased activity brownfield investments are called waves of mergers and acquisitions. Each successive wave differs from the previous one, because the environment in which businesses operate is subject to dynamic changes that generate ever new opportunities and threats. The article presents the main trends in the international strategy to acquire, as well as the scale of this phenomenon in the years 2000–2013. Also pay attention to how Polish companies find themselves in the international market of mergers and acquisitions, on the one hand – as passive actors of the process of internationalization, on the other hand – as active entities conducting international mergers and acquisitions.
Topic-oriented sarcasm detection via Entity Knowledge-based prompt learning
Authors: Zhou Yuhao , Zhang Shunxiang , Wang Caiqin , Wang Yanhui , Wang Xiaolong , Li Kuanching
Published: November 2024

The extensive spread of sarcasm on social media has attracted great attention
to sarcasm detection. Topic-oriented sarcasm detection aims to determine the
sarcastic tendency of a comment on a specific topic. Existing methods focus
on using topics as contextual information to enhance comprehension of
comment semantics. However, when topics and comments contain entities with
knowledge information, accurately understanding the comment semantics
becomes challenging. To this end, we investigate an Entity Knowledge-based
Prompt Learning (EKPL) model that combines prompt learning and entity
knowledge from knowledge graphs for topic-oriented sarcasm detection.
Specifically, we use prompt learning to transform topic-oriented sarcasm
detection from a classification task to a mask prediction task, while we
incorporate entity knowledge into the prompt representation to enhance the
expressiveness of its predictive mask words and the model's understanding of
text semantics. Experimental results on the public ToSarcasm1 dataset
illustrate that our EKPL model has a significant performance in
topic-oriented sarcasm detection task.
Study on heat transfer performance of spiral fin plate collector
Authors: Xu Ying , Shi Jingyi , Ren Zhuangzhuang , Liu Xiaoyan , Nie Xin
Published: November 2024

As an important equipment for solar thermal utilization, solar collector is
the key to improve energy efficiency and reduce carbon emissions. However,
in order to improve the heat transfer capacity of solar collectors, further
optimization of their design and performance is the focus of current
research. Although the addition of traditional ribs strengthens the lateral
air flow, it also increases the heat transfer cavity between the heat
transfer mass and the heat absorbing plate. Therefore, in this paper, a new
spiral finned flat plate collector is designed from the perspective of the
synergistic flow of the heat exchanger mass in the transverse and
longitudinal directions. The flow and heat transfer mathematical model of
the new collector is established, and numerical simulations are carried out
to analyze the effects of the ribbed deflector width and spiral pitch on the
collector efficiency. The results show that the heat transfer capacity of
the new collector is significantly higher than that of the flat plate
collector. In addition, for the spiral rib with a rib height of 38 mm and a
diameter of 25 mm, the optimal deflector width is 16 mm, the spiral pitch is
160 mm, and the deflector angle is 33.92?.

Published: November 2024

Peste des petits ruminants (PPR) is a severe and highly communicable disease. It is viral disease that particularly affects shoats. Its domino effects are economic losses through loss of production, deaths, abortions, and the cost of disease control. An outbreak investigation was conducted from May to November 2022 in Bambase district of Benishangul Gumuz regional state to determine the presence of PPR virus, and morbidity, mortality and case fatality rates. Altogether, 180 clinically diagnosed and 32 shoats with typical clinical sign of PPR were identified for laboratory confirmation Nasal and rectal swabs from 32 sheep and goats were collected and cultured on Verodog SLAM (VDS) cell line and tested using then tested using a quantitative real-time polymerase chain reaction (RT_PCR) assay and conventional PCR with 1.5% gel electrophoresis for detection of the N gene. The overall morbidity, mortality and case fatality rate was 17.77%, 2.77% and 15.62% respectively. Meanwhile, goats had a higher morbidity (26.5%), mortality (4.81%) and case fatality rate (18.18%) than sheep (10.3%, 1.03% and 10% respectively). Half (50%; 16/32) of samples were successfully cultivated on Vero dog SLAM cell line, showing cytopathic effects of PPR virus such as rounding cells, foamy vacuolation, aggregation and syncia formation. Out of 32 animals tested, 17 (53.13%) showed positive results for PPR virus by real-time PCR. Further analysis with conventional PCR revealed the presence of the N gene in all 17 positive samples with a 351bp fragment size. The results showed a higher morbidity rate in caprines than in ovines. Based on these findings, it is recommended to carry out a further phylogenetic study to identify the strain of virus circulating in the study area.

A NATUREZA JURÍDICA DA DESAPROPRIAÇÃO INDIRETA
Authors: Oliveira Thiago Emanoel Azevedo de
Published: November 2024

Este artigo examina a desapropriação indireta como uma forma peculiar de intervenção estatal sobre a propriedade privada, destacando que, embora não siga um procedimento formal específico, possui respaldo legal e uma fundamentação sólida tanto na jurisprudência quanto na doutrina. A análise dos resultados à luz da literatura revela uma convergência quanto ao caráter excepcional da desapropriação indireta, além de sua íntima conexão com a função social da propriedade. O estudo também identifica a existência de procedimentos assemelhados, mas que possuem uma natureza jurídica distinta, reforçando a singularidade desse instituto. O artigo assume relevância ao discutir o aparente conflito entre princípios constitucionais, como o interesse público e a proteção ao direito de propriedade, ambos consagrados na Constituição Federal. A solução para esse conflito exige uma ponderação cuidadosa, que harmonize a necessidade de intervenção estatal com a garantia dos direitos individuais. Assim, o objetivo principal é assegurar a reparação integral dos danos sofridos pelos proprietários afetados, em conformidade com os princípios constitucionais, como a função social da propriedade e o devido processo legal, de modo a equilibrar a proteção dos direitos privados e o atendimento das demandas coletivas.

This study focuses on enhancing the maintenance processes of centrifugal pumps at Soekarno-Hatta Airport’s Water Treatment Unit in Indonesia, crucial for meeting the clean water needs of the airport, which served around 19.8 million passengers in 2022. Using a qualitative methodology, the research involved focus group discussions with the unit’s operators, technicians, and engineers to pinpoint maintenance challenges and devise solutions. Key findings reveal issues such as insufficient routine maintenance, unplanned repairs, and inadequate staffing, leading to operational disruptions and pump failures. The study highlights the role of Total Productive Maintenance (TPM) in reducing machine breakdowns and improving efficiency. It emphasizes the critical role of centrifugal pumps in the airport’s water supply system. The research proposes several corrective measures, adhering to the 5W + 1H framework, including regular lubrication, bearing replacements, hiring more staff, and advanced training on PLC systems. These actions aim to rectify immediate maintenance problems and establish a foundation for the long-term effectiveness of the pump systems. Conclusively, the study underscores the need for a comprehensive maintenance strategy that aligns with standard operating procedures and preventive maintenance. This approach is essential for boosting the operational performance and reliability of the Water Treatment Unit. It has broader implications for similar infrastructure facilities, underscoring the importance of efficient maintenance management.
Human dignity and the pursuit of knowledge in Islamic thought: Insights from the Quran
Authors: Elouazzani Lahcen
Published: November 2024

This research examines the interplay between human dignity and the pursuit of knowledge within Islamic thought, using insights from the Quran. It explores how Islamic epistemology emphasizes the harmonious integration of divine revelation and human reason, underscoring the importance of knowledge as a key factor in both intellectual and spiritual development. By analyzing the contributions of classical Islamic scholars, such as Al-Farabi, Ibn Sina, and Al-Ghazali, alongside Western epistemological traditions, the study highlights complementary and contrasting approaches to understanding knowledge and its role in shaping ethics and governance. Furthermore, the research draws on contemporary case studies, such as the Marrakesh Declaration and Masdar City, to illustrate how Quranic principles of cooperation, justice, and environmental stewardship can inform modern societal frameworks. Ultimately, the study argues for the continued relevance of Islamic thought in addressing contemporary global challenges, emphasizing that the pursuit of knowledge not only advances scientific discovery but also promotes human dignity, justice, and societal well-being.

Subject and purpose of work

Cooperatives offer significant opportunities for economic empowerment of people in difficult economic climates. However, concerns exist in literature on the efficiency level of these organisations in relation to members’ deposits and financial-related factors. This study analysed the influence of members’ deposits and related financial factors on the efficiency level of cooperative organisations.

Materials and methods

Data Envelopment Analysis (DEA) and the Tobit regression model were used to analyse the secondary data collected from 99 cooperative organisations over 7 years.

Results

Empirical results indicate a low level of efficiency below 50%. Further evidence from Tobit regression identified the significant effect of loan (β = 2.05, t = 3.41, p < 0.01), interest rate (β = 1.07, t = 2.16, p < 0.05), surplus (p < 0.05), expenses (p < 0.01), cooperative age (p < 0.01) and saving deposits (p < 0.10) on cooperative efficiency.

Conclusions

The efficiency level of cooperatives is low, and the contribution of deposits is also negative, but potential to raise the level of efficiency exists with organisational management of loans and interest rates. Increasing cooperative efficiency is imperative to achieve the expected economic support from organisations.
From greenwashing to green marketing – an approach to change consumer behaviour towards environmental issues in emerging countries
Authors: Bouchareb Nasser
Published: November 2024

This study proposes greenwashing as a paradigm for altering consumer attitudes toward environmental challenges in emerging countries. This technique uses greenwashing as a planned obsolescence strategy to shift consumer attitudes toward environmental issues and eventually transition to a true green marketing approach. Despite the adverse perceptions connected with greenwashing, the study contends that it can play an important role in raising awareness about environmental concerns and promoting more responsible behaviour. It is important to be aware that greenwashing should not be considered to be a long-term solution. Government intervention is required to regulate and enforce acceptable practices in order to accomplish real change. The primary goal of this study is to provide a clear understanding of greenwashing’s function in influencing consumer views.
