Dysfunctional attitudes,social support,negative life events,and depressive symptoms in Chinese adolescents:A moderated mediation model

BACKGROUND Depression is a prevalent psychological issue in adolescents that is significantly related to negative life events(NLEs)and dysfunctional attitudes.High levels of social support can significantly buffer NLEs’effect on depression.Currently,there is limited research on how social support moderates the relationship between NLEs,dysfunctional attitudes,and depression in adolescents in China.It is imperative to investigate this moderating effect to mitigate dysfunctional attitudes in adolescent undergoing depressive mood,ultimately enhancing their overall mental health.AIM To investigate the relationship and underlying mechanisms between specific dysfunctional attitudes,social support,and depression among Chinese adolescents.METHODS This is a cross-sectional study which selected five middle schools in Shandong Province for investigation in March 2022.Participants included 795 adolescents(49.87%male,mage=15.15,SD=1.84,age range=11-18 years old).All participants completed the Dysfunctional Attitude Scale,Adolescent Life Event Scale,Beck Depression Inventory,and Social Support Rating Scale.A moderated mediation model was conducted to examine the relationship between specific dysfunctional attitudes,social support,and depression.RESULTS Results indicated that NLEs affected depression through the mediating role of specific dysfunctional attitudes(autonomy attitudesβ=0.21;perfectionismβ=0.25).Moreover,social support was found to moderate the mediating effect between NLEs,specific dysfunctional attitudes,and depressive symptoms(autonomy attitudes b2=-0.08;perfectionism b2=-0.09).CONCLUSION Dysfunctional attitudes mediated and social support moderated the relationship between NLEs and depression.Social support can buffer depression symptoms among adolescents with autonomy attitudes and perfectionism.

The Impact of Nursing Staff’s Work Attitude on the Fear of Patients Recovering from Benign Tumors:Family Support as a Mediating Variable

The perception of nursing staff’s attitude influences patient fear.Understanding this dynamic is crucial for fostering a supportive environment conducive to patient well-being and effective healthcare practices.The purpose of this research is to investigate how the attitudes and behaviours of nursing staff influence the fear and anxiety levels of patients recovering from benign tumors,aiming to improve patient care and recovery outcomes.Data was collected from a sample of 100 participants,comprising 20 nursing staff and 80 patients recovering from benign tumors.Surveys were administered to gather quantitative data on attitudes and fear levels.Participants were selected randomly from hospital records and outpatient clinics.Our analysis encompassed nursing staff attitude,patient fear levels,the influence of family support,progression of tumor recovery,patient-reported satisfaction,and the quality of healthcare services provided.The quantitative aspect utilized PLS-SEM software to perform regression analysis,evaluating both direct and indirect effects.Statistical analysis assessed the relationships between nursing staff attitudes,patient fear during benign tumor recovery,and the mediating role of family support.The findings of the study demonstrate that better nurse attitudes(Hypothesis 1,β=0.45,p<0.001)and stronger family support(Hypothesis 2,β=0.32;p<0.001) are linked to lower levels of patient fear.Partially mediating the relationship between nurse attitudes and patient fear,according to Hypothesis 3(β=0.28,p<0.002),is family support.Patients’perceptions of family support are highly influenced by nursing behaviour,as demonstrated by Hypothesis 4(β=0.38;p<0.001).Our research showed a strong relationship between the attitudes of nursing personnel and patient fear levels.Family support demonstrated a strong mediating effect on patient fear.Patient-reported satisfaction is positively correlated with family support.However,no significant relationship was found between healthcare service quality and patient fear.

Residents’ Attitudes Towards Tourism in a Globally Important Agricultural Heritage Systems Pilot Site: a Case Study in China

Globally Important Agricultural Heritage Systems (GIAHS) is a wide program to promote the conservation and adap-tive management of such systems and their associated landscapes, biodiversity, knowledge systems and cultures. Rice-Fish Systems (RFS) in Longxian village of China, as a traditional agricultural system, was selected as one of the five pilot sites of GIAHS in 2005. Researchers have paid more attention to the dynamic conser-vation and adaptive management of RFS because it is under severe threats from global development challenges. Tourism is suggested to be brought into the RFS conservation program as an alternative industry. This paper presents a comparative study of residents in three types of farm household in Longxian, seeking attitudes to the RFS conservation and tourism development and ways in which such information may guide future strategies. Results show resi-dents, belonging to the household type in which most family mem-bers are abroad, have the most positive attitudes to RFS conserva-tion and tourism development; while residents, as other household type in which less than 50% of family members are abroad, are the least sensitive group in these three household types, due to the motivation of moving abroad weakening their enthusiasm to participate in the local activities. Implications are discussed in the context of how resident attitudes will affect the future manage-ment of GIAHS conservation and tourism development, and then measures are put forward to foster tourism cooperation and multi-stakeholders process establishment.

TOD residents' attitudes toward walking to transit station: a case study of transit-oriented developments(TODs) in Bangkok,Thailand

The study aims to analyze the attitude toward walking to the stations of residents living within 1 km of transit stations, or they are called transit-oriented development(TOD) residents. They are highly expected to walk to transit station and use rail in their daily travel. In this research, 249 respondents are asked 10 questions on attitudes of walking to station. The analysis was conducted in two stages: factor analysis and structural equation model. As the current access mode of respondents,walkers are more likely to be low-income households.People using motorized mode are mostly from middle-to high-income, households the largest group of respondents.For walking acceptance, high-income group accepts distance and time shorter than other incomes. Low-income households can accept the longer walking distance but shorter time. Middle-income households are more likely to walk in shorter distance than lower-income households,but they tend to accept longer walking time than others.As for the analysis results, the feeling of walking among all respondents significantly influences the walking acceptance. The benefit of walking significantly influences walking acceptance only among middle-income households. The walking attitudes on convenience, safety, a sense of freedom, healthiness, and environmental friendliness highly affect respondents' acceptable walking distance and time in TODs.

Basic life support:knowledge and attitude of medical/paramedical professionals

BACKGROUND:Basic life support(BLS),a key component of the chain of survival decreases the arrest-cardiopulmonary resuscitation interval and increases the rate of hospital discharge.The study aimed to explore the knowledge of and attitude towards basic life support(BLS)among medical/paramedical professionals.METHODS:An observational study was conducted by assessing response to self prepared questionnaire consisting of the demographic information of the medical/paramedical staff,their personnel experience/attitude and knowledge of BLS based on the 2005 BLS Guidelines of European Resuscitation Council.RESULTS:After excluding incomplete questionnaires,the data from 121 responders(27 clinical faculty members,21 dental and basic sciences faculty members,29 house officers and 44 nurses and health assistants)were analyzed.Only 9(7.4%)of the 121 responders answered≥11,53(43%)answered 7-10,and 58(48%)answered<7 of 15 questions correctly.The clinical faculty members,house officers and nurses/HA had a mean score of 7.4±3.15,7.37±2.02 and 6.63±2.16 respectively,while dental/basic sciences faculty members attained a least mean score of 4.52±2.13(P<0.001).Those who had received cardiopulmonary resuscitation(CPR)training within 5 years obtained a highest mean score of 8.62±2.49,whereas those who had the training more than 5 years back or no training obtained a mean score of 5.54±2.38 and 6.1±2.29 respectively(P=0.001).Those who were involved in resuscitation frequently had a higher median score of 8 in comparison to those who were seldom involved or not involved at all(P<0.001).CONCLUSIONS:The average health personnel in our hospital lack adequate knowledge in CPR/BLS.Training and experience can enhance knowledge of CPR of these personnel.Thus standard of CPR/BLS training and assessment are recommended at our hospital.

Assessment of knowledge and attitude about basic life support among dental interns and postgraduate students in Bangalore city,India

BACKGROUND: Life-threatening emergencies can occur at anytime, at anywhere and in anyone. Effective management of an emergency situation in the dental office is ultimately the dentist's responsibility. The lack of training and inability to cope with medical emergencies can lead to tragic consequences and sometimes legal complications. Therefore, health professionals including dentists must be well prepared to deal with medical emergencies. This study was undertaken to assess the knowledge about and attitude towards basic life support(BLS) among dental interns and postgraduate students in Bangalore city, India.METHODS: A cross sectional survey was conducted among dental interns and postgraduate students from May 2014 to June 2014 since few studies have been conducted in Bangalore city. A questionnaire with 17 questions regarding the knowledge about and attitude towards BLS was distributed to 202 study participants.RESULTS: The data analyzed using the Chi-square test showed that dental interns and postgraduate students had average knowledge about BLS. In the 201 participants, 121(59.9%) had a positive attitude and 81(40.1%) had a negative attitude towards BLS.CONCLUSIONS: Cardiopulmonary resuscitation should be considered as part of the dental curriculum. Workshops on a regular basis should be focused on skills of cardiopulmonary resuscitation for dental students.

Factors associated with financial support in old age for young and middle-aged rural residents in China

This study examined the factors associated with financial support in old age from three primary mechanisms-personal savings,family support,and social insurance-to explore the implications for the future development of China's rural social welfare system.Cross-sectional surveys of 1392 young and middle-aged rural residents were conducted in July and August2012.The results showed that while social insurance was increasingly acceptable,personal savings and family support still had fundamental value.Combining the three mechanisms,the rural old-age welfare system presented nontraditional features.China's new rural endowment insurance is discussed as a means to address the need for financial support among the rural aging population.

This study was a good opportunity to raise awareness among health professionals about the interest of biobanks in the development of biomedical research in Eastern Morocco.

The Mediating Effect of Quality of Life on Tourism Impact and Support Attitude in Alishan Tribes

The purpose of this study was aimed to analyze the effect of indigenous people’s perceived impact of tourism development on tribal quality of life and the support attitude toward tourism development. The research subjects were indigenous people who were at least 20 years old and came from one of eight Alishan tribes in Taiwan. This study conducted an investigation by random sampling, a total of 850 questionnaires were distributed and obtained 827 valid questionnaires. The valid return rate was 97.29%. Statistical analysis was performed on the valid questionnaires using descriptive statistics and partial least squares (PLS). According to the analytical result, Alishan indigenous people feel the negative environmental impact brought by tourism is the highest, but in terms of quality of life, they also maintain of nature and culture. When the positive economic, environmental, and sociocultural impact of tourism is higher, tribal quality of life and indigenous people’s support attitude toward tourism development will be more significant;however, when the negative economic, environmental, and sociocultural tourism impact is higher, tribal quality of life will be lower and indigenous people will tend to resist tourism development. Quality of life was found to be a moderator between tourism impact and support attitude toward development. This study proposed suggestions for indigenous tribes and the government to develop the tourism sector and introduced specific research directions for future tribal tourism researchers.

Community attitudes toward ecotourism development and environmental conservation in nature reserve:a case of Fujian Wuyishan National Nature Reserve,China

Using social exchange theory, this study investigated residents＇ attitudes toward the preliminary stage of tourism development in nature reserves in Wuyishan National Nature Reserve of China, and the socio-economic and negative effects of residents＇ attitude toward the tourist industry. Results of the questionnaire survey indicated that local people perceived they could benefit from the economic activities related to tourism, and were supportive of the conservation of natural resources and local culture, sustainable community development, and community participation in ecotourism planning and management. This study also revealed that the variables of age, gender, education level, household income, family size, non-farm work arrangements, and the distance to tourism attractions, have significant association with respondents＇ attitudes toward ecotourism development, or negative impacts of the tourist industry. Respondents who are male, or have a higher household income, are more supportive of tourism development inside the reserve. Younger and more highly educated community members are more likely to support learning more about natural and cultural resources and landscapes. Respondents who have a hieher household income, or live far fromthe village center, are more concerned about the negative environmental impacts of tourism development.

Sociodemographic characteristics, cultural biases, and environmental attitudes: An empirical application of grid-group cultural theory in Northwestern China

Natural resource-management studies have become increasingly attentive to the influences of human factors. Among these,cultural biases shape people’s responses to changes in natural resource systems. Several studies have applied grid-group cultural theory to assess the effects of multiple value biases among stakeholders on natural resource management. We developed and administered a questionnaire in the Heihe River Basin(n = 364) in northwestern China to investigate the appropriateness of applying this theory in the Chinese context of natural resource management. The results revealed various cultural biases among the respondents. In descending order of prevalence, these biases were hierarchism(46.98%), individualism(26.65%), egalitarianism(18.96%), and fatalism(2.78%), with the remaining respondents(4.67%) evidencing no obvious bias. Our empirical study revealed respondents’ worldviews and the influence of sociodemographic characteristics on cultural biases, as theoretically posited. Among the variables examined, age had a positive and significant effect across all biases except individualism. The correlation of income to all cultural biases was consistently negative. Only education had a negative and significant effect across all biases. Women were found to adhere to egalitarianism, whereas men adhered to individualism and hierarchism. Thus, grid-group cultural theory was found to be appropriate in the Chinese context, with gender, age, education, and income evidently accounting for cultural biases. Relationships between environmental attitudes and cultural biases conformed with the hypothesis advanced by grid-group cultural theory. This finding may be of value in explaining individuals’ environmental attitudes and facilitating the development and implementation of natural resource-management policies.

Communication Skills Training for Residents: Which Variables Predict Learning of Skills?

Objective: This study aimed to determine variables associated (predictors and correlates) with the learning of assessment and supportive skills in the context of a communication skills training for medical residents. Methods: Learning was measured by comparing residents’ communication skills in a simulated consultation before and after a communication skills training. Communication skills were transcribed and tagged with a computer-assisted program. Potential variables associated with learning (residents’ characteristics, contextual characteristics and pre-training communication skills) were measured before the training and entered in regression analysis. Results: Fifty-six residents followed the training between 2002 and 2006. Poor pre-training assessment and supportive skills predicted the respective learning of these skills. Better assessment skills’ learning was predicted by copings (i.e. lower level of emotional coping), lower levels of self-efficacy and depersonalization. Better supportive skills’ learning was predicted by a lower work experience and associated with a higher training attendance rate. Conclusions: Predictors and correlates of assessment and supportive skills learning were different. Trainers needed to detect certain residents’ characteristics (i.e. depersonalization) in order to optimize assessment skills learning. Trainers needed to be aware that supportive skills are difficult to learn and to teach and may need more training hours.

Inverse Model Control for a Quad-rotor Aircraft Using TS-fuzzy Support Vector Regression

An inverse model control based on TS-fuzzy support vector regression( TS-fuzzy SVR) for a quadrotor aircraft is developed. The TS-kernel is the product of linear combination of input and a cluster of output corresponding to a cluster of TS-type fuzzy rules. The output of TS-fuzzy SVR is a linear weighted sum of the TSkernels. The dynamical model of the quad-rotor aircraft is derived. A new control scheme combined with TSfuzzy SVR inverse model control and PID control is presented so that the TS-fuzzy SVR inverse model control enhances capabilities of disturbance rejection and the robustness while the PID control enhances fast responsiveness and reliability of the system. Simulation results show the capabilities of the developed control for the attitude system of quad-rotor aircraft.

基于PSO−ELM的综采工作面液压支架姿态监测方法

针对基于惯性测量单元的液压支架姿态解算方法会产生累计误差、校正结果不准确的问题,提出一种基于粒子群优化(PSO)−极限学习机(ELM)的综采工作面液压支架姿态监测方法。以液压支架顶梁俯仰角为监测对象,采用倾角传感器和陀螺仪采集液压支架顶梁支护姿态实时信息,对采集到的数据进行预处理,将处理后的数据输入PSO−ELM误差补偿模型中,得到解算误差预测值;同时通过卡尔曼滤波融合进行液压支架姿态解算,得到解算值;再用误差预测值对解算值进行误差补偿,从而求得更加准确的顶梁支护姿态数据。该方法只考虑加速度和角速度数据与解算误差的关系,不依赖具体的物理模型,可有效降低姿态解算累计误差。实验结果表明:液压支架顶梁俯仰角平均绝对误差由补偿前的1.4208°减少到0.0580°,且误差曲线具有良好的收敛性,验证了所提方法可持续稳定地监测液压支架的支护姿态。

“指日可待”还是“道阻且长”?——目的地居民对中国入境旅游恢复的感知形成研究

以疫情为代表的突发公共卫生事件一度使中国出入境旅游市场陷入失衡,旅游业遭受严重打击。基于日渐宽松的出入境政策等客观事实,入境旅游的恢复或迎来希望,相应地,为入境旅游重新启动做好准备工作的相关议题应当在研究中得到重视。居民是目的地旅游活动的重要参与主体,文章从目的地居民视角出发对中国入境旅游恢复感知作预测研究,以深度访谈为资料来源,用扎根理论方法探索影响目的地居民对中国入境旅游恢复的感知过程与作用路径。研究发现:(1)政策与现实、风险认知、利益关切与个体内置情感是影响居民感知的因素;(2)信息源、信任情感积累、控制性/补偿性需求能够调节感知强度;(3)居民的感知结果包含“爱恨交织”的复合情绪,亦包含对来华游客潜在态度感知;(4)衍生感知后效包含整合行为、逃离行为、主动寻求防护行为和排斥来华游客行为4种行为倾向。

国家公园旅游对当地居民自然保护态度的影响机制——以神农架国家公园试点区为例

建立国家公园体制是我国建设生态文明、美丽中国以及实现人与自然和谐共生的现代化的重要抓手。当地社区居民是国家公园建设和管理的重要利益主体,也是参与国家公园自然保护的重要力量,如何培育当地居民积极的自然保护态度对于国家公园的建设和管理具有重要现实意义。以神农架国家公园试点区为例,基于刺激-有机体-反应(S-O-R)模型,引入地方依恋变量,构建了旅游影响感知、地方依恋和自然保护态度之间的结构关系模型,运用多群组嵌套结构方程模型(SEM)揭示了国家公园发展旅游对当地居民自然保护态度的影响机制。研究表明:(1)神农架国家公园试点区居民对旅游影响的感知对其自然保护态度有显著的直接影响;(2)地方依恋在神农架国家公园试点区居民旅游影响感知与其自然保护态度之间发挥着中介作用;(3)在旅游影响感知、地方依恋和自然保护态度之间的结构关系上,参与旅游的居民和未参与旅游的居民之间存在显著的群体差异。主要表现为前者对负面旅游影响的感知对其地方依恋感和自然保护态度均没有显著影响,而后者对负面旅游影响的感知对其地方依恋感和自然保护态度有显著影响。研究的理论贡献主要有两点:一是通过引入地方依恋作为中介变量,揭示了国家公园旅游影响当地居民自然保护态度的作用路径;二是通过参与旅游居民和未参与旅游居民两个群体的比较分析,进一步揭示了国家公园旅游影响当地居民自然保护态度的群体差异。
