To address the challenges of high computational complexity and the tendency to get stuck in local optima during at- tribute reduction within traditional rough set theory, this paper proposed an innovative rough set attribute reduction algorithm based on differential teaching-learning optimization (AR-DTLBO). Leveraging the global search capabilities of the differential teaching-learning optimization algorithm along with the strengths of rough set theory in handling imprecise and uncertain data, the algorithm aimed to optimize the process. Firstly, it enhanced the teaching-learning optimization algorithm by introducing an adaptive teaching factor and a differential mutation strategy, thereby enhancing its search capabilities and optimization performance. Subsequently, it refined the attribute reduction process through the improved teaching-learning optimization algorithm s teaching and learning phases, effectively reducing the dimensionality and complexity of datasets. Finally, it conducted comparative experiments between the proposed AR-DTLBO algorithm and six other algorithms, using eight datasets from the UCI database. The experimental results demonstrate that the proposed algorithm achieves favorable outcomes in terms of reduction length, reduction time, reduction rate, and classification accuracy. This successful reduction and optimization of datasets not only reduces redundant information but also enhances the precision of decision rules. These findings provide valuable sup- port for decision analysis, data mining, and other related fields. [ABSTRACT FROM AUTHOR]

为阐明酚类化合物的抗氧化机理及利用其协同增效作用延缓油脂氧化，对油茶籽油中游离酚（free phenolics, FP）、酯化酚（esterified phenolics, EP）及不溶性结合酚（insoluble-bound phenolics, ISP）的提取工艺进行优化，并采用Schaal烘箱法研究不同形态酚类化合物单独或复配作用对油茶籽油氧化稳定性的影响，分析不同形态酚类化合物的互作关系。结果表明：FP的最优提取工艺条件为料液比1∶ 15、提取温度45 ℃、提取时间1.5 h、提取次数3次，EP的最优提取工艺条件为碱解液与乙酸乙酯体积比1∶ 1、萃取次数3次，ISP的最优提取工艺条件为NaOH浓度0.25 mol/L、料液比1∶ 3、碱解时间6 h、碱解温度45 ℃。在最优条件下，油茶籽油中FP、EP及ISP含量分别为（4343±2.05）mg/kg、（28.67±1.51）mg/kg及（65.87±1.34）mg/kg。不同形态酚类化合物均具有抑制氧化产物生成，增强油脂氧化稳定性的作用，其中EP+ISP的抗氧化性最强。各互作组分在油脂中均呈一定的拮抗作用，其中FP+EP+ISP的拮抗作用最强。 In order to clarify the antioxidant mechanism of phenolic compounds and use their synergistic effects to delay the oxidation of oils, the extraction processes of free phenolics (FP), esterified phenolics (EP) and insoluble-bound phenolics (ISP) were optimized, and the Schaal oven method was used to study the effect of different forms of phenolic compounds alone or in combination on the oxidative stability of oil-tea camellia seed oil, and the interaction between different forms of phenolic compounds was analyzed. The results showed that the optimal extraction process conditions of FP were obtained as follows: material-liquid ratio 1∶ 15, extraction temperature 45 ℃, extraction time 1.5 h, and extraction times 3. The optimal extraction process conditions of EP were obtained as follows: volume ratio of alkaline solution to ethyl acetate 1∶ 1, and extraction times 3. The optimal extraction process conditions of ISP were obtained as follows: alkaline hydrolysis time 6 h, alkaline hydrolysis temperature 45 ℃, NaOH concentration 0.25 mol/L and material-liquid ratio 1∶ 3. Under the optimal conditions, the contents of FP, EP and ISP in oil-tea camellia seed oil were (43.43±2.05) mg/kg, (28.67±1.51) mg/kg and (65.87±134) mg/kg, respectively, and the different forms of phenolic compounds had the effect of inhibiting the formation of oxidation products and enhancing the oxidative stability of the oil. The combination of EP and ISP had the strongest antioxidation activity. Each of the interacting components had a certain antagonistic effect in the oil, and the antagonistic effect of the combination of FP, EP and ISP was the strongest.

Due to the highly competitive nature of sports, coaches tend to adopt strict, controlling behaviors to ensure that athletes apply themselves to their training. Such behavior is thus an important and frequent research topic. Studies in Western contexts mostly adopt self-determination theory and find that demanding behavior by coaches negatively affects athletes’ motivation and well-being. However, scholars in East Asian contexts take a different perspective. Specifically, claiming that the coach–athlete relationship reflects the hierarchical and relational principles of Confucianism, these scholars argue that as coaches are responsible for developing athletes’ potential, instructing athletes, and honing athletes’ skills, East Asian athletes regard demanding behaviors by their coach, such as demanding that athletes achieve high goals, as confirmation of their coach’s belief in their potential and ability. To integrate these different theoretical perspectives from different cultural contexts and contribute to the literature on demanding behaviors by coaches, this study reviews recent research in both Western and Eastern contexts to illustrate the differences and similarities. The results provide directions for future research. It is hoped that follow-up research will further examine demanding behavior by coaches to enhance academic understanding and identify practical implications. [ABSTRACT FROM AUTHOR]

Ovarian cancer is a malignant tumor of the female reproductive system with the highest mortality, and involves the aberrant regulation of multiple molecular signaling pathways. As a highly conserved molecular pathway, Wnt signaling pathway plays an important role in embryonic development, tissue homeostasis, and tumorigenesis. Wnt signaling pathway includes canonical Wnt/β -catenin pathway and non-canonical pathway, and the latter mainly includes Wnt/planar cell polarity (Wnt/PCP) pathway and Wnt/Ca2+ pathway. Previous studies have mainly focused on the relationship between the canonical Wnt pathway and tumor progression. Recently, the non-canonical Wnt pathway has gradually received attention, and related researches have enriched the understanding of the non-canonical Wnt pathway in physiological and pathological processes such as tissue development and tumorigenesis. The existing studies suggest that the nonclassical Wnt pathway is abnormally regulated in ovarian cancer and is closely related to the staging and prognosis of ovarian cancer. Non-classical Wnt pathway plays an important role in many biological processes such as proliferation, migration and invasion of ovarian cancer cells, and the changes of this pathway are also related to chemotherapy resistance of ovarian cancer. This article reviews the role of the non-canonical Wnt pathway in ovarian cancer, and discusses the research progress of targeted therapy based on the non-canonical Wnt pathway, aiming to provide new ideas for the development of novel targeted drugs.

Suriana maritima is a coastal ornamental plant species distributing only on the South China Sea Islands in China, at present. In order to understand the ecological and biological characteristics of S. maritima, we investigated the morphological and anatomical structure of stem and leaf, the antioxidant enzyme activity and osmotic adjustments contents in leaf of S. maritima, and nutrient element contents in leaf and soil of S. maritima growing on the Paracel Islands, by field investigation and sampling for analysis. The results were as follows:(1)S. maritima had small and thick leaf, well-developed palisade tissue, and low stomatal density(8.64 n·mm-2), which make it easy to maintain water in the body and suitable for drought and high saline-alkali environments. The chlorophyll content(0.76 mg·g-1)of the leaf was low, the total antioxidant capacity(589.50 U·g-1)and proline content(1 123.64 μg·g-1)were high, indicating that S. maritima had high photosynthetic utilization efficiency and strong antioxidant capacity.(2)Though the nutrient in natural growing soil was poor, the contents of organic carbon, nitrogen and phosphorus in leaf of S. maritima were relatively high(490.27, 18.10, and 3.81 g·kg-1, respectively), indicating a high nutrient utilization efficiency and good adaptability of S. maritima to poor soil. In conclusion, S. maritima has a good adaptability to the environment of strong radiation, drought, high saline-alkali and poor soil on tropical coral islands, and can be used as a tool species for revegetation and landscaping on tropical coral islands. The results provide a theoretical basis for its protection, development and utilization. [ABSTRACT FROM AUTHOR]

Paternalistic leadership refers to a leadership style that is deeply rooted within Chinese cultural characteristics and has attracted great attention in the field of sports. Although didactic behavior is a key concept underlying paternalistic leadership, little in-depth attention has been paid to didactic behavior in sports management, including a lack of development for specific didactic behavior constructs. The most significant didactic leadership pattern is the positive discipline behavior of "reprimanding" or "scolding." Coaching through reprimanding is common within the field of sports and is commonly experienced by athletes. Reprimanding behavior from coaches can have positive teaching and education value. In the context of Chinese culture, a strict reprimanding response, which aims to constrain and regulate individual behavior by triggering feelings of shame, is regarded as an effective method for improving individual performance. However, many studies treat verbal reprimanding behavior as having harmful intent, such as in the context of corporal punishment or deprivation, ignoring the positive intentions associated with reprimanding behavior in a didactic leadership context, where it often serves as a well-intentioned attempt to establish leadership expectations. To fill this knowledge gap, this study aimed to explore the teaching and educational value of didactic leadership by conducting a systematic review of past literature, including classical and ancient books, and further proposing serial propositions based on dramaturgical theory. Specifically, coaches apply the principle of "reflecting on misconduct" when reprimanding athletes who display behaviors of misconduct and laziness and the principle of "expressing expectations" when athletes are deemed able to improve and break through themselves. These behaviors convey evaluative information, inducing a feeling of shame in the athletes and evoking the desire to "follow the rules" and "work hard and fight bravely," based on the ideas of confirmation theory and selffulfilling prophecy. A discussion of the past literature findings and suggestions for future leadership practices in sports coaching are offered. [ABSTRACT FROM AUTHOR]

In order to explore the ecophysiological adaptability of Hernandia nymphaeifolia to the tropical coral islands with harsh conditions of seasonal drought, strong light, and saline-alkali soil, we investigated the morphological and anatomical structures, antioxidant capacity, content of osmotic adjustments, and photosynthetic pigments in leaves of H. nymphaeifolia individuals that grown on the experimental nursery in Wenchang City, and that transplanted to the tropical coral islands, Hainan Province. The results were as follows:(1)Compared to H. nymphaeifolia plants grown in the experimental nursery, those plants transplanted to the tropical islands had lower specific leaf area(by 33%)and stomatal density(by 15%), thicker leaf(by 36%), more developed spongy tissue and more closely arranged palisade tissue(by 24% and 80%, respectively), which enable it to make more efficient use of light and water resources, to improve photosynthesis and to reduce transpiration, in the coral island environment.(2)After transplanted to the coral islands, the chlorophyll content of H. nymphaeifolia significantly decreased(by 86%), while proline content, superoxide dismutase, catalase, and peroxidase activity significantly increased(by 130%, 615%, 209% and 369%, respectively), which can protect its photosynthetic system and avoid the damage of plant cell membrane permeability caused by the adverse environment of coral islands. Our results indicated that H. nymphaeifolia had good ecophysiological adaptability to the environment of drought, strong light and saline-alkali soil in tropical coral islands. Therefore, H. nymphaeifolia can be used as a tool species for vegetation restoration on tropical coral islands and coastal areas. [ABSTRACT FROM AUTHOR]

In view of the large number of unlabeled high-dimensional data, this paper studied unsupervised feature selection in machine learning, and proposed an unsupervised feature selection algorithm combining self-representation similarity matrix and manifold learning. Firstly, it constructed the similarity matrix by the self-expressiveness property of the data. Based on the idea that low-dimensional manifold could represent high-dimensional data structures, it established an unsupervised feature selection optimization model considering manifold learning. Secondly, in order to ensure the selection of more useful and sparse features, it used the 12, 1 norm to constrain the optimization model, so that features competed with each other and eliminated redundancy. Furthermore, it solved the optimization model by alternating iteration of variables, and proved convergence of the algorithm. Finally, it demonstrated the effectiveness of the proposed algorithm by comparison with other unsupervised feature algorithms on four data sets. [ABSTRACT FROM AUTHOR]

Previous studies on the sports team have mainly focused on the common phenomenon that coaches take strict control to require players to work hard in training. Many researchers have explored this phenomenon from the theoretical perspective of authoritarian leadership. Although these studies have accumulated preliminary results, they are mostly limited to qualitative interviews, but not directly examine the relationship between coaches' authoritarian leadership style and players' effort. Therefore, whether the authoritarian leadership can really encourage the players to put more efforts in training is still a puzzle and an important research void. In order to fulfill this void, this study adapts the dual dimensional model of authoritarian leadership, dividing authoritarian leadership into dominance-focus authoritarian leadership and discipline-focus authoritarian leadership. Also, taking the perspective of leadership contingency theory, we propose that player's goal orientation is an important boundary condition. According to the data of 348 college players, discipline-focus authoritarian leadership enhances the player's hard work; and the impact becomes nonsignificant when the player has a high avoid performance goal orientation or a high prove performance goal orientation. On the other hand, dominance-focus authoritarian leadership has a negative impact on the player's hard work behavior only if the player has a low prove performance goal orientation. In this way, this study clarifies whether the strict control of the coach really encourages the players to work harder and fulfill the lack of research in the past for this important phenomenon.

Based on the norm of reciprocity and role obligation, this study suggests that benevolent leadership (BL) might not only have positive effect on creative performance (CP) through psychological safety (PS) but also have negative effect on CP through subordinate obedience (SO). However, prior research has only found the positive relationship between BL and CP under certain situation. It is not clear regarding how and when BL influences CP negatively. In order to fill up the research gap, the present study investigated the mediating effect of PS and SO on the relationship between BL and CP as well as identifying job autonomy (JA) as a moderator that influence the mediating effect of PS and SO. Using 185 dyad of supervisors and subordinates as samples, the study found that BL influences CP positively through PS; however, BL does not have negative impact on CP via SO. Furthermore, JA significant moderated the mediating effect of BL on CP via SO. When JA is high, the negative mediating effect of SO is weaker; when JA is low, the negative mediating effect of SO is stronger. This study extends the creativity literature by exploring the m ediating process between BL and CP. [ABSTRACT FROM AUTHOR]
