Psychological Healing: a Theoretical Exploration of the Effects of Horticultural Therapy on College Students’ Subjective Well-Being

The purpose of this study was to examine how horticultural therapy affects the subjective well-being of college students. Through theoretical analysis and literature review, the study focused on the role of horticultural therapy in mental health promotion, emotion regulation, self-efficacy enhancement, and creativity and cognitive function enhancement. It was found that horticultural therapy can significantly improve the mental health of university students, especially in stress management and emotional stability. Participation in horticultural activities helped to increase students’ life satisfaction, reduce negative emotions, and enhance their self-efficacy and sense of achievement. In addition, horticultural activities have been found to promote creative thinking and cognitive development. Nonetheless, there are challenges to implementing horticultural therapy, including resource and space constraints, and inconsistent participation. This study proposes that integrating horticultural therapy in a university setting requires a combination of resource allocation, curriculum design, and interdisciplinary collaboration. In summary, horticultural therapy demonstrates the potential to be an effective tool for enhancing the subjective well-being of university students, but its successful implementation requires further strategic planning and research.

Effects of change management on public service delivery: The mediating role of organizational culture

Several change initiatives that have been introduced in Ethiopian public organizations to address growing quest for effective public service delivery, have not achieved the desiredoutcomes. Although considerable empirical studies conducted on organizational change, few gave attention to the management of change and its impact on organizational culture and service delivery in the context of public organizations in Ethiopia. By adopting planned change management framework, this study delves into how change management in public organizations affects service delivery directly and indirectly through organizational culture. Using explanatory research design, first survey questionnaires were administered to 301 participants selected through stratified sampling across 16 public organizations in Oromia, the largest state in Ethiopia. Results of astructural equation modeling analysis revealthat change management has no significant direct effect on public service delivery, but has an indirect significant positive effectthrough theorganizational culture which fully mediates the relationship. Subsequent thematic analysis of qualitative interview data collected from 10 managers demonstrate that change management in public organizations is less effective and driven intuitively without any change management framework. The results imply that effective change management significantly improves public service delivery by fostering supportive or constructive organizational culture. The use of change management framework substantively improves change planning, understanding, communication and implementation as well as positive work culture and hence improves effectiveness of service delivery. Accordingly, theoretical and practical implications of the results are discussed.

The Influence of L2 on L1 in Tone Perception: A Case Study of L2 English- L1 Mandarin Speakers

Tones are categorized as super segmental elements which can distinguish meaning in some languages such as Chinese, Vietnamese. While in some other non-tonal languages such as English, French, tones are utilized to express the emotions of the speaker or to form interrogative sentences.Many researches have probed into the effect of L1 on L2 perception and production extensively in many aspects. However, the effect of L2 on L1 is still less known and not be studied broadly and thoroughly. Tone judging tasks are adopted as the main method to explore the influences of L2 on L1. The conclusion is that immersion English environment will slightly weaken Mandarin speakers’ original tone perception sensitivity as L1 words retriving speed becomes slow.

A Study on the Application of Group Cooperative Learning Model in the Teaching of Introduction to Education

Introduction to Education is an important course for training students to have a comprehensive understanding of the discipline of education. Traditional teaching methods are difficult to stimulate students’ enthusiasm for learning and promote in-depth thinking. In order to solve this difficulty, a group co-operative teaching mode has been introduced, aiming to integrate the dual objectives of group co-operative discussion and in-depth exploration of the subject. This can update teachers’ teaching concepts, change the status quo of students’ passive acceptance of knowledge, stimulate students’ learning initiative, and cultivate students’ ability of inquiry learning and cooperative learning. However, the adoption of group co-operative teaching in teaching is not without challenges. Problems such as insufficient understanding of the subject matter, as well as the efficiency of teamwork and independent learning, can arise in students’ independent learning and group work.

Effect of different organic nutrient solutions and day of harvest on growth, biomass yield and chemical composition of hydroponically grown sorghum

An experiment was carried out to investigate the effect of different organic nutrient solutions and day of harvest on growth parameters, biomass and chemical composition of hydroponically grown sorghum red fodder. The experiment was a 3 × 2 factorial design comprising of 3 nutrient solutions (cattle, poultry and rabbit) and 2 harvesting regimes (8th and 10th day). Cattle, poultry and rabbit dungs were collected fresh and processed into nutrient solutions. Sorghum red seeds were treated, planted on trays, and irrigated twice per day with organic nutrient solution according to the treatments. Growth parameters which were investigated included fodder mat thickness, seedling height, leaf length and width, number of leaves, fresh and dry matter yield; and proximate composition. The results showed that sorghum red fodder irrigated with cattle manure nutrient solution (NS) harvested at 10 days was higher in all, except one (fodder mat thickness) of the growth parameters considered. The crude protein (CP) was highest and similar (P > 0.05) for Poultry NS harvested at 8 and 10 days, and Cattle NS at 10 days (13.13%, 12.67%, and 12.69% respectively). The ash content also favored Cattle NS at 10 days. Cattle NS at 10 days harvest was significantly (P < 0.05) the highest (7.00%), but comparable (P > 0.05) with Rabbit NS at 10 days for NDF. Fresh and DM yields were highest for Cattle harvested at 10 and 8 days respectively. The study recommends Cattle NS as hydroponic organic NS for sorghum red as it enhances fresh and dry matter yields, and nutritive values.

Enhancing strawberry fruit growth in hydroponic greenhouse: Synergistic effects of biochar and humic acid

Hydroponics is a modern agricultural system that enables year-round plant growth. Biochar, derived from apple tree waste, and humic acid were investigated as a replacement for the Hoagland nutrient solution to grow strawberries in a greenhouse with three replications. Growth parameters, such as leaf area, the average number of fruits per plant, maximum fruit weight, and the weight of fresh and dry fruits, were measured. A 50% increase in fresh and dry fruit weight was observed in plants grown using biochar compared to the control. Additionally, the use of Hoagland chemical fertilizer led to a 25% increase in both fresh and dry weight. There was a 65% increase in the number of fruits per plant in the biochar-grown sample compared to the control. Moreover, biochar fertilizer caused a 100% increase in maximum fruit weight compared to the control and a 27% increase compared to the Hoagland chemical fertilizer. Biochar had a higher pH compared to the Hoagland solution, and such pH levels were conducive to strawberry plant growth. The results indicate that biochar has the potential to enhance the size and weight of fruits. The findings of the study demonstrate that biochar, when combined with humic acid, is a successful organic hydroponic fertilizer that improves the quality and quantity of strawberries. Moreover, this approach enables the more efficient utilization of garden waste.
