Abstract： Faced with the pressures of academic achievement, employment, and other life stressors, contemporary young people are experiencing heightened levels of anxiety and unease. Their spiritual and cultural needs are continuously evolving, necessitating the exploration of additional avenues for psychological solace. Contemporary art spaces have emerged as one of the primary means through which the public can satisfy these needs. As a result, their public responsibility has become increasingly apparent. In recent years, there has been a gradual shift towards incorporating art therapy into these spaces as part of their developmental transformation. This article begins by categorizing the spatial presentation of art therapy and analyzing its inherent logic and operational mechanisms. It then delves into exploring the interactive relationship between individuals, art therapy, and contemporary art spaces in order to seek out common ground for their mutual development potential.

Abstract： [Purpose/significance] This paper aims to serve the decision-making of solutions to problems in the product design process, meet the demand of knowledge retrieval and reuse, and guarantee the sustainable development of products. [Method/process] Based on the double-cycle model of knowledge crystallization, it found that there are problems in the existing IBIS (issue-based Information System) model and its improvement model. Therefore, the knowledge crystallization double cycle model was used to connect the discussion dialogue model and the product design process, to construct the ‘IBIS representation supporting the product double cycle model’. In the original discussion dialogue model, ‘take the large or fetch small operators’ was used in fuzzy comprehensive decision making. However, because of this operator, some useful elements will be invalid, so ‘take the large or fetch small operators’ was replaced by the Einstain operator. [Results/conclusions] The Einstain operator draws on the idea of ‘take the large or fetch small operators’ to ignore the useless value data, and highly reducts the data at both ends. The IBIS representation supporting the product double cycle model has made the product design process decision service modeling based on the knowledge crystallization double cycle theory has a basic model framework, and the improved discussion dialogue model makes the core algorithm reliable.

Abstract： [Purpose/Significance] As rural entrepreneurship advances continually, exploring the impact of agricultural information services on entrepreneurial performance is of great significance for accelerating the transformation of scientific and technological achievements and driving rural entrepreneurship. [Method/Process] Based on the theory of information and empirical data collected via "pilot work on the monitoring and investigation of the innovation and entrepreneurship of rural", this paper takes new professional farmers as the research object and constructs a panel threshold model with the level of agricultural information service supply as the threshold variable. With the model, the influence mechanism of agricultural information service supply level on entrepreneurial performance of new professional farmers is explored to reveal the relationships between agricultural information services and entrepreneurial performance. [Results/Conclusions] Results show that the impact of agricultural information services on the entrepreneurial performance of new professional farmers is not a simple linear relationship, but a non-linear one with a "single threshold" effect. When service supply crossed the "threshold level", the promotion effect was weakened by 43.6% . It confirms that information technology productivity paradox also existed in the development process of rural entrepreneurship. Therefore, strategies of agricultural information service supply can be formulated according to actual conditions to avoid excessive investment. At the same time, measures such as improving the quality of farmer education and accelerating the construction of rural entrepreneurship infrastructure can be combined to achieve an effective improvement on the quality of rural entrepreneurship.

Abstract： Understanding the cognitive mechanisms underlying word segmentation has been an important focus for research on Chinese reading. Previous research shows that Chinese readers can identify words very efficiently even though the Chinese script does not use spaces between words or other visual cues to demarcate word boundaries. One possibility is that Chinese readers can make use of their knowledge of the positional frequency of characters (i.e., how often they are used as the first or second character in words) to facilitate the word segmentation and recognition. Nevertheless, this potential role for position frequency remains controversial. Accordingly, with the present research we used the lexical decision task and eye movements during reading to investigate the use of positional frequency information about the first and second character of two-character words in both visual word recognition and reading. Four experiments were conducted to explore the effects of character positional frequency. In Experiments 1a and 1b, we manipulated both first and second character positional frequency (high vs. low) for target words that were of either high or low lexical frequency. Sixty college students were instructed to perform visual lexical decision tasks on words and pseudo-words. In Experiment 2a and 2b, we used measures of eye movements to investigate the use of character positional frequency in natural sentence reading. Sixty college students were required to read sentences while their eye movements were recorded using an EyeLink 1000 eye-tracker (sampling rate = 1000 Hz). The results of Experiments 1a and 1b revealed an effect of first character positional frequency in both the accuracy and latency of lexical decisions only for target words with low lexical frequency, and no effect of second character positional frequency regardless of the lexical frequency of the target word. The results of Experiment 2a and 2b showed a clear effect of first character position frequency on reading times (gaze duration, regression path reading time, and total reading time) for target words of low lexical frequency only, and no effect of second character positional frequency for either high or low frequency target words. Participants made shorter response times and fixation duration in high character positional frequency condition than in low character positional frequency condition for target words with low lexical frequency. In sum, findings from both the lexical decision task and measures of eye movements in reading reveal a privileged role for first character positional frequency as a cue to word segmentation and recognition. However, this influence of character positional frequency depends on word frequency, and is only observed for words of lower lexical frequency. We argue that these findings support the augmented addressed morphology model theory of Chinese word recognition, and can help inform the development of a model of character positional processing model in Chinese reading.
