As an important participant in the regional characteristic agricultural industry, the level of intelligence in the production process of new agricultural management entities is closely related to the development quality of the regional characteristic agricultural industry. By conducting research on the new agricultural management entities surrounding the golden passion fruit industry in Jingxi City, Guangxi, this study analyzes the current status of smart agricultural technology application among this group and the influencing factors of the adoption of smart agricultural technology by these entities. The results showed that the adoption of smart agricultcrral technology by new agricultural mangagement entities is affected by five factors: farmers's professional guality, farmers' risk awareness, land fragmentation degree, industrial support degree, and main organization strucrure. And based on the current situation, preliminary development strategies such as strengthening the construction of production infrastructure, enhancing the cultivation of farmers' digital literacy, diversifying the development of business entities, and establishing demonstration bases to drive promotion have been proposed.

The transformation of economic structure and the deepening of market economy make farmers have more employment and development opportunities, also have brought many opportunities and challenges to agricultural production. In order to meet the needs of agricultural modernization, more and more farmers consider agriculture as a career to choose and develop. Therefore, based on the survey data of 619 rural households in Jiangxi Province and the dimensions of occupational cognition, the Logit-ISM model was established to analyze the influencing factors and internal mechanism of farmers’ occupational willingness, the conclusions are as follows: In the aspect of farmers’ occupational cognition, the evaluation of occupational identity, the perception of scale management risk, the demonstration of successful cases and the understanding of related policies have a significant positive impact on farmers’ professionalization willingness. In addition, the control variables also have a significant impact on the willingness to professionalize, family income per capita, the proportion of agricultural income and village traffic is positive, village terrain is negative correlation. At the logical level, the proportion of agricultural income and per capita household income further affected the perception of scale management risk through the evaluation of occupational identity, the demonstration of successful cases and the understanding of relevant policies, thus affecting the willingness of farmers to professionalize. Village topography and traffic are the deep root factors, and farmers’ scale management risk perception is the surface factor. [ABSTRACT FROM AUTHOR]

Objective To analyze the reasons of late HIV diagnosis in Chengdu, and to provide scientific basis for promoting early detection. Methods A cross - sectional survey was used, and the questionnaires were conducted among HIV/AIDS cases in 9 districts in Chengdu. The socio - demographic data, AIDS knowledge awareness, health seeking habits, testing behavior and other information were collected. The chi - square test and binary Logistic regression model were used to analyze the influencing factors. In - depth interviews were conducted, and the sample size was determined according to the principle of "information saturation". Results A total of 757 HIV/AIDS cases were investigated, of which 258 (34. 1% ) were found late diagnosis. Multivariate Logistic regression analysis showed that the risk of late diagnosis was higher in age group 30 - 49 years old ( aOR = 3. 350, 95% CI: 1.725 -6.506) and "50 years old ( aOR = 3. 913, 95% CI: 1. 876 -8. 161) than 18 -29 years old. Passive detection ( aOR =2. 002, 95% CI: 1. 098 -3. 649) had a higher risk of late diagnosis than active detection. High school education or higher (aOR =0.472, 95% CI: 0.289 -0.770) had a lower risk of late diagnosis than middle school education or lower. Among the 258 late diagnosis cases, 218 (84. 5% ) never had the idea of HIV testing in the past, mainly because they had not heard of AIDS ( 106 cases/48. 6% ) and felt that AIDS was far away from them ( 82 cases/357. 6% ) . Among the 40 cases who had ever considering taking an HIV test, 17 (42.5%) did not take, mainly because they were worried about their privacy being exposed ( 12 casesZ70. 6% ), worried about what others think during the test process ( 7 cases/41. 2% ), and worried about being discriminated against if they tested positive (7 cases/41. 2% ). In - depth interviews were conducted on 16 patients with late diagnosis. The reasons for late diagnosis mainly included $ never heard of AIDS, serious misunderstanding of AIDS cognition, lack of risk perception awareness, and fluke mentality. Conclusion In order to effectively reduce the level of late HIV diagnosis, it is necessary to promote high - quality AIDS health education, improve the awareness of AIDS knowledge and risk perception after high risk behaviors, and encourage people with high risk behaviors to take the initiative to receive HIV testing as soon as possible. Building a supportive social environment to avoid giving up active testing for fear of discrimination is also essential. [ABSTRACT FROM AUTHOR]

Objective To explore the potential categories and influencing factors of complication risk perception in inpatient with type 2 diabetes mellitus. Methods A total of 400 patients with type 2 diabetes mellitus who were hospitalized in three tertiary - level hospitals in Tangshan city from August 2023 to January 2024 were randomly selected and included in the whole group. General information questionnaire, Risk Perception Survey - Diabetes Mellitus, Connor - Davidson Resilience Scale, Brief Illness Perception Questionnaire were used for investigation. Using multi - categorical logistic regression analysis to explore the influencing factors. Results Inpatients with type 2 diabetes could be divided into high confidence low disease risk perception group ( 40.25% ), appropriate risk perception group ( 40% ), and high concern high disease risk perception group ( 19. 75% ) . Multi - categorical logistic regression analysis showed that high disease perception score( OR = 0. 808, 95% CI, 0. 762 - 0. 858 ) was a protective factor for the high confidence low disease risk perception group, high psychological resilience score( OR = 1. 159, 95% CI, 1. 087 - 1. 235 ) was a risk factor for the high confidence low disease risk perception group; educational attainment of college and above ( OR = 23. 567, 95% CI,2. 807 - 198. 242 ), having diabetes complications ( OR = 3. 408,95% CI: 1. 315 -8.834), high disease perception score ( OR = 1.320, 95% CI, 1. 202 - 1. 451) were risk factors for the high concern high disease risk perception group, the main access to diabetes knowledge was healthcare professionals ( OR = 0. 101, 95% CI,0. 029 -0. 355) and high psychological resilience score ( OR =0. 817, 95% CI-.0. 747 -0. 894) were protective factors for the high concern high disease risk perception group. Conclusion Perceived risk of complications in inpatients with type 2 diabetes can be categorized into 3 classes, and there are obvious classification characteristics among groups. Healthcare professionals can implement precise measures for different categories of patients to improve their level of perceived risk of complications. [ABSTRACT FROM AUTHOR]

Objective To explore the impact pathways of cognitive decline, risk perception, and self-efficacy on the safe medication practices of empty nesters, utilizing the risk perception attitude framework theory. Methods A stratified cluster random sampling method was employed to conduct a questionnaire survey involving 361 empty nesters. Multiple linear regression analysis and structural equation modeling were used to construct the impact pathways. Results The average score for safe medication practices among empty nesters was 30.59±3.61. Path analysis revealed that cognitive decline directly predicted safe medication practices β=-0.134) and also indirectly influenced these practices through risk perception and self-efficacy. This included the independent mediating effects of self-efficacy β=-0.066) and risk perception β=-0.131), as well as the chain mediating effect of risk perception and self-efficacy β=-0.088) (all P<0.05). Conclusion The level of safe medication practices among empty nesters urgently needs improvement, particularly focusing on those with cognitive decline. Enhancing self-efficacy and correcting risk perception biases may elevate safe medication practices among cognitively impaired empty nesters. [ABSTRACT FROM AUTHOR]

How to achieve intelligent, safe and efficient mining of rockburst coal seams is a major engineering and technical challenge facing deep coal mining. The core connotation of this issue lies in the intelligent, unmanned, and inherently safe mining of coal seams with rockburst. Through accurate perception and intelligent early warning of coal and rock burst risks, as well as self-adaptation and self-optimization of mining engineering, intelligent anti-burst and mining control technologies are formed to achieve a fundamental shift from engineering-induced disasters to engineering-prevented and mitigated disasters. By implementing measures such as mining source design, roof area fracturing, localized targeted management, and strengthening roadway support, a low-stress environment and safe roadway space are created for the safe and efficient mining of coal seams with rock burst. On this basis, a big data analysis software platform that integrates static geological, dynamic monitoring, working conditions, personnel positioning, production organization, historical data and other information, as well as an intelligent mining control system that integrates impact pressure decision-making information, has been developed. The anti-impact information source has been transformed into an intelligent mining control source, forming a new flexible intelligent mining model of "low pressure fast pushing, medium pressure slow mining, and high pressure production stop". Field application shows that in the intelligent anti-impact and control mining area, the degree of mine pressure in working face and roadway is smaller,, and the energy release of coal and rock is more stable, which is conducive to the reasonable release of impact mine production capacity.

Objective To understand the HIV infection risk perception bias and its related influencing factors among young men who have sex with men (MSM) in Shandong Province, so as to provide reference for making feasible HIV health education plans. Methods From April to July, 2022, young MSM were recruited in six cities in Shandong province, and a questionnaire survey was conducted and blood samples were collected to collect demographic characteristics, HIV risk perception and risk behavior of MSM. Logistic regression model was used to analyze the influencing factors of HIV infection risk perception bias among young MSM. Results A total of 978 MSM were investigated, of which 85%(831/978) were over 20 years old, 97.6%(955/978) were unmarried/divorced or widowed, 61.1%(598/978) were college educated, 2.6% (25/978) were positive for HIV antibody and 3.6%(35/978) for syphilis antibody. 47.1%(461/978) had HIV infection risk perception bias, of which 54.0%(249/461) underestimate the risk and 46.0%(212/461) overestimate the risk. Logistic regression analysis showed that unmarried/divorced/widowed (OR = 11.693, 95%CI: 1.546-88.407) and having no or low risk of new drugs (OR = 2.041, 95%CI: 1.477-2.825) were the risk factors for underestimating the risk. Household registration in Shandong province (OR = 2.618, 95%CI: 1.397-4.902), college education or above (OR = 1.728, 95%CI: 1.206-2.475), homosexuality (OR = 2.532, 95%CI: 1.093-5.845), having general or high risk of new drugs(OR = 8.323, 95%CI: 4.602-15.052), who had not received AIDS intervention (OR = 2.288, 95%CI: 1.224-4.292) and had not taken preventive drugs before exposure (OR = 11.905, 95%CI: 3.663-38.462) were the risk factors for overestimating the risk. Conclusion HIV infection risk perception bias among young MSM in Shandong Province is high, and HIV risk behaviors are widespread. It is necessary to strengthen the education of MSM who have low self-rated HIV infection risk but have high-risk behaviors, improve risk awareness and reduce the occurrence of dangerous behaviors.

This paper used a binary Logistic regression model to analyze the impact of farmers′ drought risk perception on their adaptation intention based on farmer survey data to strengthen farmers′ ability to adapt to climate change and improve the resilience of agroecological systems to climate change. The results showed that farmers′ perception of the severity of drought risk is ranked from high to low, as parttime farmers, multiple occupations farmers, non-farmers, and pure farmers. Their adaptive perception is ranked from high to low, as nonfarmers, pure farmers, multiple occupations farmers, and part-time farmers. Part-time farmers have the strongest perception of the severity of drought risk and the lowest adaptive perception, while pure farmers have the lowest perception of the severity of drought risk and the highest adaptive perception. It can be seen that there is a complex nonlinear correlation between farmers′ perception of drought risk and their intention to adapt. 47.5% of the surveyed farmers were willing to actively respond to the drought risk, and the adaptation intention of part-time farmers and multiple occupations farmers with higher non-agricultural level was stronger. 72.34% and 58.33% of the farmers have positive adaptation intention, 36.19% of the pure farmers have positive adaptation intention, and the proportion of non-farmers is only 23.08%. There is a positive correlation between adaptation perception, adaptation motivation, natural capital, physical capital, social capital, and adaptation intention. Based on this, the paper proposes some countermeasures and suggestions to improve farmers′ adaptability to drought risk in northern China′s agro-pastoral ecotone. [ABSTRACT FROM AUTHOR]

Falls are the important causes of morbidity and mortality in older adults. Although clinical staff have paid attention to the management of falls, adherence to fall interventions is not satisfactory, resulting in the high incidence of fall. Understanding the older adults' own perception of fall risk from their perspective may be the key to fall prevention, especially active fall prevention. In this paper, we reviewed the concept of fall risk perception, behavioral consequences and influencing factors of fall risk perception in older adults from the perspective of "the first person responsible for health", and found that there are fewer studies on fall risk perception in older adults at home and abroad, the conceptual connotation still needs to be further explored. Subjective perceptions of fall risk in older adults can lead to different patterns of fall risk coping behaviors that influence fall risk. The influencing factors of fall risk perception mainly focus on the emotional psychology, physiological conditions, social culture, and physical environment, with the influencing process through subjective cognition. Empirical studies can be used to further validate the psychological cognitive mechanisms of fall risk perception in conjunction with the risk perception formation process in the future, in order to provide empirical evidence for proactive fall prevention.

(1) Background-The reform of China's collective forest property rights system has increased the risks that individual farmers need to bear in forestry management, and also increased the demands of individual farmers to control and disperse forestry management risks. However, even with the continuous optimization of forest insurance guarantee level, the proportion of farmers' commercial forest insurance is still relatively low, which may not only restrict the release of the potential of China's forest insurance market, but also affect the modernization and high-quality development of China's forestry industry. (2) Methods-The research data mainly came from the field survey carried out by the research group in 2018 and 2020, and a total of 2252 valid questionnaires were obtained. In this paper, the farmers' decisions of commercial forest insurance were selected as the explained variables, risk perception, insurance cognition, insurance burden and forestland emotion were selected as the explanatory variables, and the farmers' personal characteristics, family management characteristics and market price characteristics were selected as the control variables. Based on the insurance demand theory of the decision-making process, this paper constructed a random effects Panel Probit model, and discussed the effects of different influencing factors in the decision-making process of the farmers' commercial forest insurance from both theoretical and empirical perspectives. (3) Results-First, in terms of risk perception, when the farmers' perception of forestry management risk increases by 1%, their possibility of buying commercial forest insurance will increase by 26.7%, that is, the farmers with higher forest management risk perception are more likely to insure commercial forests. Second, in terms of insurance cognition, when the farmers' satisfaction with forest insurance and recognition of premium standard increase by 1%, their probability of buying commercial forest insurance will increase by 11 % and 8.4%, respectively, indicating that higher insurance satisfaction and recognition of premium standard will promote the farmers' commercial forest insurance behavior. Third, in terms of insurance burden, for every unit increase in household income of the farmers, the probability of the farmers buying commercial forest insurance will increase by 0.6%, that is, the farmers with high income are more likely to buy commercial forest insurance. Fourth, in terms of forestland emotion, every 1 % increase in the farmers' dependence on forestland will increase the possibility of their buying commercial forest insurance by 3%, indicating that the higher the farmers' dependence on forestland, the more likely they are to make insurance decisions. (4) Conclusions and Discussions-Based on the above research conclusions, the following policy suggestions are put forward: First, strengthen farmers' awareness of preventing forestry management risks and improve farmers' cognition of forest insurance. Second, increase the support for the purchase of commercial forest insurance, so as to reduce the burden of farmers participating in commercial forest insurance. Third, deepen the reform of forest property rights system and regulate market prices reasonably. Fourth, formulate differentiated forest insurance policies to promote the diversified development of forest insurance. [ABSTRACT FROM AUTHOR]

BACKGROUND: Most balance disorders after total hip arthroplasty require a variety of rehabilitation methods to improve. Body weight support Tai Chi footwork can be used as a safe and effective balance training method. OBJECTIVE: To observe the effect of body weight support Tai Chi footwork on the balance function of patients after total hip arthroplasty. METHODS: Totally 74 subjects undergoing total hip arthroplasty were recruited and randomly divided into a control group (n=37) and a trial group (n=37). The control group received 30 minutes of body weight support walking training and 60 minutes of routine rehabilitation training; the trial group received 30 minutes of body weight support Tai Chi footwork training and 60 minutes of routine rehabilitation training, once a day, 5 times a week, for 12 consecutive weeks. Before the intervention, 4, 8, and 12 weeks after intervention, the Berg balance scale and the dynamic balance ability test were used to evaluate the balance function. Harris score was used to evaluate the hip joint function, and the fall risk index was used to evaluate the fall risk. RESULTS AND CONCLUSION: (1) The four observation indicators all showed significant time effects (P < 0.001). (2) Berg balance scale, Harris score and fall risk index all had an interaction effect (P < 0.001), and there was a significant inter-group difference after 12 weeks of intervention (P < 0.001), and the effect of the trial group was better than that of the control group. (3) After 12 weeks of intervention, there was an interaction and group effect in the scores of the front and left directions of the dynamic balance test (P < 0.001), and there were significant group differences in the scores of the overall, front, left and right directions (P < 0.001). (4) The results showed that after 12 weeks of intervention, the balance functions of the trial group and the control group were improved, and the improvement effect of body weight support Tai Chi footwork training was better than body weight support walking training on patients after total hip arthroplasty.

Objective: To elucidate the primary elements pertaining to the perception of relapse risk and to investigate the characteristics and alterations of perception of the risk of recurrence in patients with schizophrenia. Methods: By using the method of phenomenological study, semi-structured in-depth interviews were conducted among schizophrenic patients with first onset, first recurrence and multiple recurrences. Twenty-three 23 outpatient and inpatient cases that met the criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) were included, and all patients had PANSS scores below 60. The interview data were collated and analyzed according to Colaizzi analysis. Results: The perception of recurrence risk in patients with schizophrenia encompassed 4 major themes and 11 sub-themes, namely susceptibility (limited overall understanding, transition from optimism to objectivity), detection of early warning symptoms (dynamic escalation, assistance from family members in identification), understanding risk factors (lack of understanding, the relationship between psychosocial factors and relapse, dynamic understanding of medication-relapse relationship), and apprehension of the consequences of recurrence (care burden and financial constraints, impaired social functioning and maladjustment, impact on public safety, personal health risks). Conclusion: The content of risk perception of recurrence in patients with schizophrenia is relatively substantial. The overall level of risk perception of recurrence in patients with schizophrenia is low. [ABSTRACT FROM AUTHOR]

Globally, the surfing tourism industry has matured, as has the research in this sector. In recent years, surfing tourism in China has been favored by domestic risk preference tourists because it can meet the demand for adventure sports tourism, and a number of surfing tourism resorts have emerged. However, domestic-related theoretical research is obviously insufficient. Utilizing the theories of risk edge and emotion evaluation theory and taking Riyue Bay, Wanning City (Hainan Province) as the research area, tourists were surveyed in order to ascertain emotion and experience as factors to incorporate in a structural equation model. The intermediary effect analysis method was applied to explore the impact mechanism of risk perception on the intention of surfing tourists to revisit, in order to provide theoretical support and countermeasures for the sustainable development of domestic surfing tourism. The data collected in this study were verified as representational, reliable, and effective, and the model fitted the data well. Based on the results, the following two conclusions can be drawn. 1) On the one hand, risk perception has a significant direct and positive impact on emotional arousal of the surfer, and emotion plays a completely intermediary role in the impact of risk perception on intention to revisit; that is, risk perception has no significant direct impact on intention to revisit, which is in agreement with some studies and contradicts others. On the other hand, experience quality plays an intermediary role in the influence of emotion on revisit intention, and the intermediary effect is slightly higher than the direct effect. These conclusions indicate that surfing tourism operators should not only fully mobilize the positive emotions of surfers, but also find ways to let surfers obtain a higher-quality surfing tourism experience to better attract repeat visitors. In order to promote the sustainable development of surfing tourism in Riyue Bay, Wanning City, we make the following suggestions. First, risk preference tourists should be considered the main target audience in marketing. Second, management norms should be established for surfing clubs (stores) and evaluation mechanisms for surfing coaches. Third, safety supervision should be strengthened to enhance the surfing experience. Lastly, surfers should be helped to successfully surf and stimulate positive emotions. Although there are still some limitations, these preliminary results advance the field of risk perception in tourism, both in theory and in practice.

[Purpose/Significance] In social media, the complex phenomenon of group polarization caused by the effect of network circle groups has brought serious challenges to the guidance and governance of online public opinion. This paper aims to explore the influencing mechanism of multi-dimensional environmental risk perception on group polarization in the network circle groups, and provide theoretical support and insights into the management of group polarization. [Method/Process] First, based on the protective motivation theory and the circle group structure theory, risk perception was divided into three dimensions: risk fact perception, risk loss perception and risk reaction behavior perception, and a network circle group was divided into three layers: point, line and structure. Based on this, a theoretical model of the relationship between risk perception and group polarization under the background of network circle groups was constructed. Second, taking the "6.10" hitting event as an example, a questionnaire was designed to collect sample data, and two sets of comparative data were obtained from the perspectives of randomly selected women and circled female groups, and the reliability and validity of the data were tested and analyzed. Finally, Amos26.0 software was used to establish a structural equation model (SEM) for empirical analysis of the research hypothesis in this paper, and the Bootstrap method was used to test the mediating effect of network circle groups, revealing the effect of risk perception on group polarization in network circle groups. [Results/Conclusions] 1) Compared with the random female group, the degree of homogeneity in the network group is higher, and the circle group effect is significant. 2) Risk perception has a significant positive impact on the formation of group polarization, in which the perceived risk response behavior has the most significant impact on group polarization. 3) Network circle groups have a significant positive influence on the formation of group polarization, among which "structure" has the most significant influence on group polarization. 4) Network circle groups play a mediating role between multi-dimensional risk perception and group polarization. The research not only reveals the generation path of network circle groups and risk perception on group polarization and the key factors affecting the occurrence of group polarization from the theoretical level, but also provides directions for relevant departments to manage group polarization and reduce public risk perception. This study has several limitations. For instance, SEM model setting and questionnaire design depend on the subjective experience and theoretical assumptions of researchers, and may have selectivity bias, so the model setting in this paper is subjective to a certain extent.

With the massive quantification of networked data and the development of geo-social networks (GSNs), group activities are prevalent in people's life. The objects of recommendation systems are extended from individuals to user groups. Point-of-interest (POI) group recommendation problem is also gradually known as a hot research topic. However, the traditional methods are not suitable for group recommendation in geographic social networks, due to the multifactorial influence of user preferences in GSNs and the complexity of the group decisionmaking process. To reveal user preferences and the effect of the group decision process on group recommendation, this paper proposes a neural network-based model for dynamic POI group recommendation by leveraging multidimensional user preference. Firstly, the proposed model combines temporal and spatial factors to calculate user preferences based on user behavior activity records and builds a group-point-of-interest perception graph with group as unit. Next, this paper adds the influence of collaborative users to model group preferences, which fully considers the characteristics of GSNs, to ensure the accuracy of POI group recommendation. Finally, a neural network-based model can be constructed to simulate group decision-making, which can ensure the accuracy of POI recommendations. This paper conducts extensive experiments by comparing the existing group recommendation algorithms on the real datasets to demonstrate the performance of the method proposed in this paper. Experimental results show that the proposed method is significantly better than the existing algorithms in terms of the hit rate of POI, which proves the effectiveness of the proposed algorithm.

Under the guidance of national education policy, the demand for study tourism has increased significantly, and it is worth paying attention to how parents, as the actual purchasing decision-makers of study tourism products, reflect their needs and attitudes. Taking nature education study tourism as the specific research context, questionnaires were distributed to parents of primary and secondary school students to investigate the causal relationship between study tourism motivation and value perception from the perspective of parents' perception and incorporated cost perception and risk perception into the research to analyze the internal mechanism and boundary conditions between study tourism motivation and value perception. A statistical analysis of data from 539 parents revealed that parents' perception of study tourism motivation significantly and positively affects value perception. Cost perception has a mediator role between study tourism motivation and value perception, and parents' perception of study tourism motivation has a positive impact on value perception through the path of weakening cost perception. Moreover, risk perception negatively affects value perception, but a positive effect was observed when exploring risk perception's interaction with study tourism motivation and cost perception, respectively. Risk perception significantly enhances the positive effect of study tourism motivation on value perception, while suppressing the negative effect of cost perception on risk perception. Specifically, compared to low-risk perceptions, parents with high-risk perceptions perceive a more significant positive effect of study tourism motivation on value perception and a lower negative effect of cost perception on value perception; that is, risk perception plays a moderating role in the relationship between tourism motivation and value perception and in the path of the relationship between cost perception and value perception. However, when risk perception reaches a high level, its moderating effect on the relationship between cost perception and value perception is not significant; that is, parents pay more attention to risk and safety issues than to cost issues. The main theoretical contribution of this study is that it forms a theoretical complement to the investigation of the relationship between motivation and value, thus revealing the importance of the value of education for the average non-only-child family in China and cost as an important consideration for such families in their educational investment. It verifies the positive role of risk perception in the context of study tourism, which promotes further understanding of risk in the academic community and enriches the theoretical research on study tourism. In addition, this study provides a valuable empirical basis and practical enlightenment for the development of study tourism. It is necessary to design study tourism products based on demand, highlight product value, increase publicity and marketing efforts, control the safety of activities, set reasonable prices, and gain the attention of parent groups, all of which will be important considerations in further expanding the study tourism market.

Marketization of rural idle homesteads can be promoted for “three rights separation” of rural homesteads. The perceived risk can be one of the most important identification factors in the farmers’ homestead marketization in the reform of the homestead system. In this study, an evaluation system was constructed to identify the risk of homestead marketization from the perspective of farmers’ risk perception, including the risk of the farmers’ equity, cultivated land protection, collective return, social stability, ecological environment, and cultural inheritance risk. Taking Chongqing Dazu, Yongchuan, and other typical homestead system reform pilots as empirical areas, a Variable Fuzzy set was adopted to evaluate the risk level of farmers’ homestead marketization. Subsequently, an efficient machine learning model (called Random Forest, RF) was employed to identify the risk of farmers’ homestead marketization. Finally, risk prevention and control strategies were proposed under different marketization patterns. The results showed that: 1) An inverted “U” shaped fluctuation trend was found in the risk level of farmers’ homestead marketization. Specifically, the risk probability of direct marketization (43.38%) and green indicators marketization (32.14%) were significantly higher than that of marketization of reclamation indicators (13.73%), and marketization of planning adjustment (12.99%). 2) There were some differences in the various risk factors for the four types of marketization patterns. The farmers’ equity risk (46.74%) was higher in the direct marketization, whereas, the cultural inheritance risk (4.76%) was lower. The social stability risk (35.66%) was higher in the marketization of planning adjustment, while the ecological environment risk (5.85%) was lower. The cultivated land protection risk (29.13%) was higher in the marketization of reclamation indicators, while the collective return risk (2.05%) was lower. The farmers’ equity risk (34.24%) was higher in the green indicators marketization, while the ecological environment risk (1.20%) was lower. 3) There were some differences in the risk mechanism. The same risk factor also shared the heterogeneity in the homestead marketization of four types. 4) The differentiated prevention strategies of marketization risks were considered the timing, and the cooperation of various participants, such as farmers, collectives, and governments. The government, the collective, and the farmer were united to focus on the “prevention in advance” in the direct marketization. The collective was supposed to focus on the “prevention in advance” in the marketization of planning adjustment, while the government was on the “prevention afterward”. By contrast, the government was supposed to focus on the “prevention in the event” in the marketization of reclamation indicators, while the collective was on the “prevention afterward”. Only the government was supposed to focus on the “prevention in advance” in the green indicators marketization. In conclusion, the reform of homestead marketization should set the tone of “steady and prudent promotion”. It was different from the complete marketization of state-owned land. But the marketization was limited using “three rights separation”. Meanwhile, future homestead marketization should avoid homogenization patterns. More importantly, it is urgent to establish an income distribution mechanism and risk aversion system, in order to share the benefits and risks by farmers, collectives, and governments. The findings can provide the decisionmaking on rural residential land consolidation. The homestead risk database can be expected to deepen the reform of the homestead system. [ABSTRACT FROM AUTHOR]

Objective To explore the effects of perceived risk of COVID-19 of college students on their anxiety and depression, as well as the roles of attention to negative information and perceived social support, so as to provide theoretical basis for colleges and universities to formulate corresponding intervention measures. Methods By the convenience sampling method, totally 1 404 college students from Shaanxi and Henan provinces were investigated online by using General Information Questionnaire, Perceived Risk of COVID-19 Pandemic Scale, Attention to Negative Information Scale, Patient Health Questionnaire, Generalized Anxiety Disorder and Perceived Social Support Scale. SPSS 20.0 was used for data analysis, Pearson correlation method was used to explore the correlation between variables. The mediating effect of attention to negative information and the moderating effect of perceived social support were analyzed by PROCESS. Results The scores of anxiety and depression of the 1 404 college students included in the study were 4.03±4.48 and 6.21±5.41, respectively. The detection rate of anxiety symptom was 29.9%, and that of depression symptom was 44.4%. The risk perception of COVID-19 epidemic of the college students was positively correlated with attention to negative information (r=0.373, P＜0.001), anxiety (r=0.227, P＜0.001), and depression (r=0.226, P＜0.001). Anxiety (r=0.553, P＜0.001), and depression (r=0.497, P＜0.001), were positively correlated with attention to negative information, while perceived social support was negatively correlated with the risk perception of the COVID-19 (r=-0.154, P＜0.001), attention to negative information (r=-0.259, P＜0.001), anxiety (r=-0.321, P＜0.001), and depression (r=-0.278, P＜0.001). The risk perception of COVID-19 affected the anxiety and depression of the students mainly through the mediating effect of attention to negative information. The total effect of risk perception of COVID-19 and anxiety was 0.227, and the mediating effect accounted for 80.18% of the total effect. The total effect of risk perception of COVID-19 and depression was 0.228, and the mediating effect accounted for 90.35% of the total effect. Perceived social support played a moderating role in the last half of this mediating model. Conclusion Risk perception of COVID-19 indirectly affects the occurrence of anxiety and depression in college students through attention to negative information, and perceived social support plays a moderating role in this mediating model. The findings suggest that when a risk event occurs, colleges and universities should pay attention to guiding students to adjust their attentional bias to external information, and give students enough care and support to improve their mental health.

The aim of this study is to elucidate the mechanism of environmental regulations and factor endowments governing farmers′ input adoption for manure treatment, so as to improve farmers′ environmental risk perception and explore the construction strategy of rural civilization and maintenance of low-carbon circular economy. Based on surveys of farmers in major meat duck breeding provinces, the impact of environmental regulations and factor endowments on the input adoption for manure treatment was analyzed on the basis of cost and Porter effect through a multiple regression model. Furthermore, the heterogeneity of farmers′ manure treatment input adoption under different organizational forms was explored. The intensity of environmental regulations revealed an“inverted U-shaped”relationship with the input adoption of meat duck farmers for manure ′ resource treatment. Environmental regulations had impacts on such input adoption, with a value of 0.075 of guiding regulation as the highest degree of influence. In addition, the coefficients of the interaction terms of guiding regulations with commanding regulations and incentive regulations in influencing farmers′ input adoption for manure treatment were 0.062 and 0.038, respectively, with significant moderating effects. The differences in factor endowments were the main reason to drive the input adoption of farmers under different organizational forms; especially, the endowments of social and material capital, which produced remarkable effects on livestock farmers′ input adoption for manure treatment. In order to improve farmers′ awareness on manure resource treatment and promote the implementation of its input adoption, appropriate environmental regulation policies should be formulated based on local conditions through“combined regulations”, while relevant technical training, publicity, and roll-out should also be strengthened. In addition, for enhancing the effective implementation of such policies, farmers should be encouraged to actively cooperate with leading companies in livestock breeding, and optimize resource allocation in meat duck raising, so as to realize a substantial outcome for ecological and economic benefits in the meat duck breeding industry.

Objective To examine the impact of risk information characteristics on the Chinese public's risk perception of coronavirus disease 2019 (COVID-19) and to put forward targeted suggestions for improving infectious disease epidemic information release. MethodsUsing a self-designed questionnaire, we conducted an online anonymous survey among 1 446 Chinese internet users recruited with snowball sampling in five provincial-level regions of China from June 15 to 18, 2020. Results Valid information were collected from 1 292 participants (43.0% males and 56.0% females) averagely aged 30.4 ± 9.3 years. Evaluated by a scale with the highest score of 5 for the greatest impact, the scores for the impact of characteristics of COVID-19 related information on participants' the epidemic risk perception were 3.37 ± 0.98 for personal experience associated with infectious disease, 3.81 ± 1.21/3.61 ± 0.79/3.48 ± 1.13/3.52 ± 0.90/2.92 ± 0.95 for obtaining information disseminated by government departments/experts or scholars/traditional media/internet or social media/neighbors or friends, 4.36 ± 0.59 for inconsistent or contradictory information, 4.35 ± 0.61 for different or controversial information from experts or scholars, 3.74 ± 0.87 for hearing about discussions or disputes among opinion leaders such as very important Microblog users or stars, 3.99 ± 0.94 for exposed to a great amount of information about COVID-19 during the epidemic, 3.75 ± 1.00 for rarely accessing to information other than COVID-19 epidemic, 3.53 ± 1.05 for obtaining information about previous infectious disease epidemic such as severe acute respiratory syndrome and influenza, 3.57 ± 0.94 for accessing information about outbreaks of other infectious diseases in foreign countries, 2.50 ± 1.08 for obtaining information on phenomenon or problems induced by the epidemic, 3.36 ± 0.98 for accessing text descriptions/photographs/videos on severe harms caused by the epidemic, and 3.48 ± 1.13 for accessing the information on panic or sadness induced by the epidemic among the public. The 5 common factors identified through factor analysis were source, dispute, quantity, association, and sentiment tendency of information accessed, with the corresponding variance contribution rate of 17.334%, 13.638%, 13.221%, 13.111%, and 10.593%, respectively, and a cumulative variance contribution rate of 67.897% for the 5 common factors. ConclusionThe source, dispute, quantity, association, and sentiment tendency are main characteristics of COVID-19-related information affecting the public′s disease risk perception and information source is a primary factor among the five information characteristics.

Consumer’s perception of crisis risks（PCR） affects online reviews outcome particularly in the public emergency. The model of online reviews affecting consumer purchasing decision was constructed in consumer’s PCR scenarios, and the multiple regression and Bootstrap analysis were used to verify the model. The impact of online reviews including review length, review richness, and review responses on consumer purchasing behavior was discussed. Meanwhile the mediating effect of review helpfulness and the moderating effects of external perceived risks（EPR） and internal perceived risks（IPR） were considered. The results show that review helpfulness has the mediating effect; EPR has positive moderating effect while IPR has negative moderating effect. What’s more, EPR has greater effect on consumer purchasing behavior. Online reviews exert the effect on consumers’ online shopping, which is amplified by the public emergency. Therefore, e-commerce companies should improve online transaction service and online reviews supervision to decrease the consumers’ PCR of online shopping and improve the stable, orderly and sustainable development of e-commerce [ABSTRACT FROM AUTHOR]
