Comparative Evaluation of Dormand Prince and Cash-Karp Method in Lengyel Epstein Reaction Model Forming Zinc Oxide (ZnO) Nanostructures

2025-01-07T11:06:20+00:00

The current study employed two different numerical techniques to solve the Ordinary Differential Equations (ODEs) of the Lengyel Epstein reaction model. This was done for direct comparison with their results on
the production of Zinc oxide (ZnO) nanostructures using Dormand Prince and Cash-Karp methods. Furthermore, the study aimed to determine the numerical approximation that may provide an estimate for
the concentration of Zinc ion () and Hydroxyl ion (OH - ) in the growth process of a ZnO nanostructure. The current study utilized the Cash- Karp method to solve ODE used in the development of the Lengyel Epstein reaction model. Afterwards, the results obtained from this approach were compared with the Dormand Prince method to determine its efficiency. After appropriate detail analysis, it was determined that Cash-Karp yields more consistent results as compared to the Dormand Prince method. The simulation for the solution of ODEs offers a higher convergence rate when Cash-Karp method is used. The error margin of the Cash-Karp method is comparatively smaller than that of the Dormand Prince method which may also be verified by the experimental results of growth of ZnO nanostructures.

The current study aimed to investigate the relationship between light and dark triad of personality traits corresponding with healthy and unhealthy humor styles. Furthermore, it also assessed the impact of light and dark triad of personality traits as well as self-enhancing, affiliative, aggressive, and self-defeating humor styles on the social support of young adults. A quantitative study design was employed. A total of 214 participants were purposively selected from various public sector universities. Standardized instruments, namely Light Triad Scale (LTS), Short Dark Triad (SD3), Humor Styles Questionnaire (HSQ-32), and Multidimensional Scale of
Perceived Social Support were utilized for data collection. The data was statistically analyzed using correlation, regression, and t-test. The results showed that significant inverse relationship exists between light triad of personality and affiliative humor style. There is a positive correlation between aggressive humor and light triad traits. Dark triad traits are directly associated with self-enhancing, aggressive, and self-defeating humor styles, however, not with affiliative humor style. The exploration of gender differences revealed that men tend to score higher than women in light triad of personality. Likewise, men score significantly higher in aggressive humor style, whereas women score higher in perceived social support. The multiple linear regression results manifest that self-enhancing humor positively predicts social support, whereas self-defeating humor has negative impact on social support of the young adults.

Maximizing Logistics Output through Strategic Packaging Decisions: An Exploratory Study

2025-02-19T06:40:18+00:00

Recognizing the critical role that packaging plays in the overall success of a firm’s logistics initiatives, the lack of a targeted study in this area may result in missed chances to optimize logistics output. Poor packaging decisions may raise supply chain costs and threaten sustainability due to a lack of understanding of the sensitive interaction between packaging and logistics performance. Packaging is crucial to supply chain efficiency, cost, and sustainability, making it essential to a company’s logistics operations. Currently, research generally misses the influence of packaging on logistical initiatives, despite its importance.Hence, this study examines the relationship between packaging and logistics performance to offer improvements. It aims to carefully evaluate different packaging types in logistics projects, as well as to examine packaging multifaceted role in advancing sustainability, reducing waste, and ensuring product safety within the logistics framework. Further, it intends to find actionable insights on how to optimize packaging to improve logistics performance and reduce its environmental impact. A detailed mixed-method approach comprising a thorough literature review and case study analysis was conducted. This methodological fusion aimed to clarify packaging-logistics relationship. The research goal goes beyond academic inquiry. It intends to educate logistics managers and organizations with important insights by discovering the crucial links between packaging choices and logistics results, as well as supporting informed decision-making in the field of strategic packaging and supply chain management. Aside from management implications, the findings have the potential to contribute to the overall development of logistical practices by generating positive transformations associated with the principles of efficiency, sustainability, and increased awareness within the logistics environment.

Effects of Employees’ Climate Change Awareness and Comprehension on Waste Management and Pollution Control in Selected Manufacturing Companies

2025-02-19T06:50:10+00:00

Climate change poses significant global challenges, particularly in manufacturing sectors, where waste generation and pollution are prevalent. This study examines the impact of climate change awareness and comprehension on waste management practices and pollution control measures among employees in selected manufacturing companies in Lagos State, Nigeria. Using the descriptive research design, 1200 respondents
were sampled from a population of 24,000 employees across three major firms in the food and beverages industry. Data were collected via structured questionnaires and analyzed using linear regression. The findings reveal that climate change awareness significantly influences waste management practices (R2 = 0.145, β = 0.381, p < 0.05), accounting for 14.5% of the variance. Similarly, climate change comprehension significantly impacts pollution control effectiveness (R2 = 0.250, β = 0.500, p < 0.05), explaining 25% of the variance. Based on these findings, the study concludes that environmental education is critical to promoting sustainable practices within the manufacturing sector. The study recommends implementing comprehensive awareness programs and continuous training to enhance employees’ environmental knowledge and operational proficiency, thereby improving overall environmental performance and compliance with regulatory standards.

Systematic Literature Review: Impact of Post-Traumatic Stress Disorder on Entrepreneurial Intentions

2025-02-21T05:40:25+00:00

This systematic literature review aimed to explore the consequences of posttraumatic stress disorder (PTSD) due to traumatic childbirth in relation to emotional intelligence (EI) and social influence. Women make an
extraordinary contribution to regional and national production. Furthermore, the United Nations (UN) Sustainable Development Goals (SDGs) highly emphasize the mental and physical health of women. Compulsive buying is a significant issue that causes emotional, financial, and social distress to individuals and their families. Entrepreneurial intentions play a crucial role since they serve as a precursor to entrepreneurial activities influencing both individual and economic outcomes. The review period encompassed researches published from January 2014 to December 2023. Through a comprehensive examination of the literature, this review identified key dimensions and variables used to investigate the association between posttraumatic stress and entrepreneurial intentions. Several dimensions were considered in the reviewed literature including psychological factors, individual characteristics, and environmental influences. Psychological factors encompassed variables, such as resilience, coping mechanisms, and cognitive appraisal of trauma. Individual characteristics included personality traits, past traumatic experiences, and levels of self-efficacy and motivation. Environmental influences encompassed socio-economic factors, social support networks, and cultural contexts. The variables utilized in the reviewed studies involved measures of post-traumatic stress symptoms, such as intrusive thoughts, avoidance behaviors, and hyperarousal. Entrepreneurial intentions were assessed through measures of entrepreneurial self-efficacy, desire for autonomy, risk-taking propensity,
and intention to start or pursue entrepreneurial endeavors. The current study contributed to the understanding of how post-traumatic stress influences entrepreneurial intentions. Furthermore, it also highlighted the importance of considering psychological, individual, and environmental factors in research and interventions aimed at supporting individuals with posttraumatic stress who aspire to entrepreneurship.
