Previous research has analyzed the meaning and value of STEM education and explored both its current possibilities and future development. However, STEM education experts have not reached a consensus on the goals of STEM education, making its promotion more challenging. Thus, this study examined which particular STEM education goals should be emphasized through a survey questionnaire. The study employed a stratified random sampling method to collect survey data from secondary teachers of STEM-related courses (i.e., science, technology, and mathematics) in Taiwan. A total of 645 valid survey responses were collected and then analyzed by independent t-test and analysis of variance to examine teachers’ perceptions about 17 critical competencies proposed as education goals relevant to STEM education. The findings revealed that STEM teachers generally had positive attitudes and high levels of acceptance toward implementing the 17 proposed STEM education goals through integrative STEM education. However, the proposed goal of "cultivating students’ entrepreneurial capabilities" received lower scores and should not be used at the secondary level. It may be introduced as an important education goal in tertiary STEM education. In addition, STEM teachers with different backgrounds (e.g., STEM teaching experience, perceptions of STEM teaching methods) perceived the competency goals as having different levels of importance in STEM education. Teachers’ willingness to teach STEM using a transdisciplinary integration method increases when they have access to sufficient resources and support. © 2022, The Author(s), under exclusive licence to Springer Nature B.V.

Distillation aqueous byproducts are discarded despite being rich in bioactive components. In this study, the aqueous byproducts (hydrolats and flask water fractions) resulting from the hydrodistillation of fresh and dry mint leaves were compared, with a primary focus on their essential oil yield and bioactive properties. Dry mint leaves yielded approximately eight times more essential oil than fresh leaves. The hydrolat extracted from dried mint leaves (MHD) exhibited higher phenolics (35.5 ± 1.1^d mg GAE/100 mL), flavonoids (7.8 ± 0.29^d mg QE/100 mL) and 2,2-diphenylpicrylhydrazyl scavenging potential (21.13%), compared to the hydrolat derived from fresh leaves (MHF), which had lower values (7.115 ± 0.9^e mg GAE/100 mL, 5.72 ± 0.422^d mg QE/100 mL and 6.79%, respectively). Similarly, the flask water fraction from dry mint leaves (FWF2) had a higher concentration of bioactive compounds compared to that from fresh leaves (FWF1). The hydrolat with higher bioactivity (MHD) was selected for infusion to develop a flavored drink and its GCMS profile indicated a relatively abundant presence of D-Carvone. The flavored drink prepared with a 20:100 ratio of hydrolat was preferred for its flavor intensity, a key sensory parameter for determining the hydrolat amount. Additionally, for Gum Arabic, a 2.5:100 ratio in the drink resulted in a more acceptable consistency score. © 2024 Elsevier B.V.

Background: Parenting stress has grown dramatically as a result of the pandemic, according to a systematic analysis that compared parenting styles and mental health-related factors before and during COVID-19. Regarding the COVID-19 epidemic, parents reported feeling more stressed. This included anxiety about their kids' health and safety, financial hardships, and interruptions to their regular routines and support networks. Furthermore, the analysis revealed that the pandemic had a detrimental effect on parents' mental health, with greater rates of anxiety, sadness, and overall psychological distress among parents. These findings demonstrate the intricate interactions that exist between personal variables and exogenous stressors like the pandemic that affect parenting stress. The COVID-19 pandemic and other external stressors, financial hardships, and marital status are only a few of the variables that might affect parenting stress overall. Consequently, while analyzing parenting stress, creating parent support interventions, and contrasting pre- and post-COVID-19 patterns, it is imperative to take these diverse elements into account. Method: This study includes material from three well-known databases that are used by scholars all around the world: Scopus, Web of Science (WOS), and Google Scholar. The records were screened during the review process using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) methodology. Results: We evaluated 10,053 abstracts and titles found through Google Scholar and database searches. After a complete text screening of 253 publications, 18 research were included in our study. According to the data retrieved from every database, the research questions in this study are multidisciplinary in nature, reflecting the interdisciplinary nature of healthcare and the development of new healthcare technologies. The most prevalent discipline is psychology, which is followed by medicine, social sciences, environmenta

Purpose: A major paradigm shift focusing on the dark side of leadership has generated lots of concern for organizations as leadership has cascading effects on employees’ behaviour. This study aims to understand negative behaviours in the organization as a system of interrelated interaction initiated from the top which trickles down to employees. Design/methodology/approach: Drawing on the theories of social exchange and norms of reciprocity, social learning and displaced aggression, this study models how and when abusive supervision relates to employees’ task performance. The model is empirically tested and extended to cover mediation and moderation processes. Drawing data from 218 bank supervisors and employees, this study uses the structural equation modelling to analyse a trickle-down model of abusive supervision. Findings: Results from multi-waved, multi-sourced data indicated a mediating effect on the abusive supervision–performance relationships and provided support for employees’ guilt proneness and emotional dissonance as moderators. Overall, the results provided support for a moderated mediation relationship in the trickle-down model. Originality/value: This study provides new knowledge into the potential boundary conditions of employees’ guilt proneness and emotional dissonance in affecting the relationship between abusive supervision, counterproductive work behaviour and task performance. © 2020, Hannah Vivian Osei, Felicity Asiedu-Appiah and Perpetual Akosuah Anyimaduah Amoah.

The decision makers of every business firm take strenuous efforts to achieve the target of sales promotion using different marketing strategies. In recent times, advertising is becoming one of the most preferred and adopted marketing techniques to reach customers at larger magnitude. The business firms irrespective of their production sizes and scales associate with various advertising agencies to familiarize their products to the customers. The advertising strategic approach of marketing also gives rise to a decision-making problem on the optimal choice of advertising agencies as the wrong selection of the agencies harms the sales. This research paper intends to propose a decision making (DM) model integrating both multi–criteria decision methods and machine learning algorithms to make optimal selection of advertising agencies. The proposed DM model considers 25 alternatives of advertising agencies, six criteria, linguistic analytic hierarchy process (LAHP) and random forest algorithm for ranking the advertising agencies. The machine learning (ML) algorithm identifies the feasible alternatives with the help of criterion weights obtained using the method of LAHP. This method is more compatible as it minimizes the risks of decision making by grouping the alternatives into two groups of acceptance and rejection based on their likelihood. The computations are done using Python programming language especially in Google Colabs.

The research develops an intelligent aquaculture system to detect the water quality of a culture pond. Additionally, using Fuzzy Logic to evaluate water quality that influences the aquaculture livability. Each species requires a different environment of water quality;therefore, the study utilizes an intelligent aquaculture system to detect the water quality of white shrimp ponds. After using Fuzzy Logic to analyze water quality, the result is delivered as equally divided into five levels of signals sections. The purpose of the research is to understand whether the aquaculture environment is suitable for white shrimps by detecting the water quality;consequently, through studying the livability to understand the importance of water quality. From the experimental results, the water quality of targeted aquaculture ponds are all within the livability range of white shrimp;the result has shown a livability rate of 33%, which is considered high livability in marine white shrimp farming. Hence, it is concluded that water quality has a high correlation with livability. Moreover, the study demonstrates that water monitoring and water quality analysis are beneficial to monitor the aquaculture environment, which can further increase the livability of white shrimp and boost income. © 2020, ICST Institute for Computer Sciences, Social Informatics and Telecommunications Engineering.
