Review of the development of research themes in human resource management: A bibliometric co-citation analysis of the 1970s and 1980s

This study aims to explore the evolution of the human resources field in Western academia during the 1970s and 1980s, focusing on the trends in research topics across different decades. The analysis utilizes citation co-citation analysis, multivariate statistical analysis, and social network analysis. The research data were drawn from the Web of Science (WoS) database, comprising 1278 documents. By distinguishing between different time periods, the study identifies shifts in the field across two distinct time frames, visualized through multidimensional scaling maps. The results indicate that the 1970s were dominated by seven major research streams, while the 1980s introduced eight research streams, with “human resources” emerging for the first time as a prominent research frontier. The volume of literature, co-citation frequency, and citation counts all increased over time, reflecting the growing vibrancy and expanding scope of research in the field. Although citation co-citation analysis provides objective quantitative insights, issues such as the purpose of citations, the extent to which cited documents influence citing documents, and the varying layers of citation impact may introduce potential errors in the co-citation analysis results.

Accelerating First-Order Algorithms for High-Dimensional Minimax Optimization

This study introduces two first-order algorithms for high-dimensional minimax optimization: Accelerated Momentum Descent Ascent (AMDA) and Accelerated Variance-Reduced Gradient Descent Ascent (AVRGDA). These methods aim to address common challenges in nonconvex optimization, such as slow convergence and computational complexity. AMDA leverages momentum-driven techniques to smooth the optimization path, reducing oscillations and improving convergence speed, particularly in nonconvex-strongly-concave problems. AVRGDA incorporates adaptive learning rates that dynamically adjust according to gradient norms, enhancing the efficiency of variance reduction and handling complex optimization tasks in high-dimensional spaces. Through experiments in adversarial training and large-scale logistic regression, these methods demonstrate superior performance in terms of training time, robustness, and computational cost compared to traditional first-order methods. Theoretical analysis shows that AMDA and AVRGDA achieve convergence rates of O(ϵ−3)and O(ϵ−2.5) respectively in high-dimensional, nonconvex minimax problems, confirming their efficiency and robustness in practical applications.

Exploring the Relationship between Images and Text in the Picture Book “Rosie’s Walk” and Its Educational Value

The classic picture book “Rosie’s Walk,” crafted by the renowned British author Pat Hutchins, exemplifies the well-known saying that ‘within every picture book lies at least three narratives.’ Hutchins adeptly harnesses the immediacy of imagery and the succinctness of language to construct a story universe that is simultaneously instructive and captivating. This paper presents an analysis of “Rosie’s Walk,” highlighting the intricate fusion of visual elements and written narrative within the sphere of children’s literature, and elucidating how this synthesis engenders such a narrative style. Also, it delves into the pedagogical significance of this picture book.

New multi-energy sources coupling a low-temperature sustainable central heating system with a multifunctional relay energy station

Due to the short cost-effective heat transportation distance, the existing geothermal heating technologies cannot be used to develop deep hydrothermal-type geothermal fields situated far away from urban areas. To solve the problem, a new multi-energy source coupling a low-temperature sustainable central heating system with a multifunctional relay energy station is put forward. As for the proposed central heating system, a compression heat pump integrated with a heat exchanger in the heating substation and a gas-fired water/lithium bromide single-effect absorption heat pump in the multifunctional relay energy station are used to lower the return temperature of the primary network step by step. The proposed central heating system is analyzed using thermodynamics and economics, and matching relationships between the design temperature of the return water and the main line length of the primary network are discussed. The studied results indicate that, as for the proposed central heating system, the cost-effective main line length of the primary network can approach 33.8 km, and the optimal design return temperature of the primary network is 23 ℃. Besides, the annual coefficient of performance and annual energy efficiency of the proposed central heating system are about 3.01 and 42.7%, respectively.

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.
