Academic procrastination of nursing students in higher vocational college: Application of latent profile analysis and network analysis.

BACKGROUND: Academic procrastination is especially prevalent among nursing students in higher vocational colleges and it is considered an important factor of poor academic performance. However, existing research mainly focused on the overall level of academic procrastination, and little is known about the individual heterogeneity of academic procrastination among nursing students in higher vocational colleges. Thus, the aim of this study was to clarify the subgroups and factors of academic procrastination among nursing students in higher vocational college and explore academic procrastination networks of the latent subgroups. METHODS: A cross-sectional study with online survey. 1369 nursing students in one higher vocational college were recruited using convenience sampling. Participants completed electronic questionnaires that collected demographic and academic characteristics, perceived stress, and academic procrastination. Latent profile analysis, multinomial logistic regression analysis, and network analysis were performed to analyze the data. RESULTS: Three latent profiles of academic procrastination were identified: low (32.4 %), medium (53.3 %), and high (14.3 %). Higher vocational college nursing students who have reset an exam, low professional identity, and perceived more stress are more likely to have higher academic procrastination than other profiles. Network analysis showed that academic procrastination networks structure of the three latent profiles had distinct central components. For the low academic procrastination group, AP11 ("I make study plans, but I often fail to stick to them") and AP12 ("If there is no external pressure, I tend to postpone assignments or reports with deadlines") were the core components. For the medium academic procrastination group, AP17 ("I always wait until I can't postpone my academic tasks any longer before starting them") and AP16 ("I always tend to postpone on assignments or other academic tasks") were the central components. For the high academic procrastination group, AP16 and AP7 ("When studying in my dorm room, I often stop to do other things") were the essential components. CONCLUSIONS: There is heterogeneity in higher vocational college nursing students' academic procrastination that can be classified into three latent profiles. The examined factors of academic procrastination and identified the central components of academic procrastination networks of the three latent profiles help nurse educators tailor targeted interventions.

Pain Catastrophizing, Kinesiophobia and Exercise Adherence in Patients After Total Knee Arthroplasty: The Mediating Role of Exercise Self-Efficacy.

Purpose: To examine whether exercise self-efficacy mediates the contributions of pain catastrophizing and kinesiophobia to exercise adherence in patients after total knee arthroplasty. Patients and Methods: A cross-sectional study design was conducted. A total 211 post-total knee arthroplasty patients were recruited from three orthopedics units of a tertiary hospital in China. Participants were invited to complete questionnaires on pain catastrophizing, kinesiophobia, exercise self-efficacy, and exercise adherence. Mplus 8.3 software was used to construct mediation models. Results: Pain catastrophizing and kinesiophobia were negatively correlated with exercise adherence (r = -0.509, r = -0.605, p < 0.001 respectively), while exercise self-efficacy were positively associated with exercise adherence (r = 0.799, p < 0.001). The results found exercise self-efficacy mediated the correlations of pain catastrophizing and kinesiophobia with exercise adherence after adjusting for demographic and clinical covariates. Pain catastrophizing indirectly affected patients' exercise adherence through its effect on exercise efficacy (indirect effect: -0.412), while Kinesiophobia is directly associated with exercise adherence and also indirectly through exercise self-efficacy (direct effect: -0.184, indirect effect: -0.415). Conclusion: Patients after total knee arthroplasty who have high levels of psychological distress (pain catastrophizing and kinesiophobia) are vulnerable to be non-adherent to exercise behaviors. Exercise self-efficacy explains the effects of pain catastrophizing and kinesiophobia on exercise adherence and may be a key target for measures to improve exercise behaviors in patients after total knee arthroplasty.

Bibliometric Analysis in the Field of Rural Revitalization: Current Status, Progress, and Prospects.

Rural areas play an important role in global sustainable development. In recent years, however, rural development has experienced global crises, such as issues in public education, health care, roads, water and sanitation, along with environmental pollution and a lack of natural resources. It is therefore important to promote rural revitalization in the process of modernization. To objectively reveal the current research status in the field of rural revitalization, we analyzed relevant publications in the Web of Science from 1991 to 2021. The results are as follows: (1) In the past 30 years, the number of publications on rural vitalization has increased, and the period from 1991 to 2021 can be divided into three stages, the initial period (1991-2004), the development period (2005-2016), and the high-yield period (2017-2021). (2) Research on rural revitalization covered 60 countries or regions around the world, involving a total of 3099 authors. China, the United States, and Canada published most of the articles. (3) High-frequency keywords were migration, management, and urbanization, indicating that scientists considered the role of sustainable urban and rural development, policy formulation, and urbanization. We highlight that for the development of the field of rural vitalization, scientists need to further strengthen theoretical research, fully absorb the development achievements of advanced countries and regions, understand the laws and trends of urban and rural development in their own countries, and explore new paths to achieve rural vitalization.

Land Use Dynamic Evolution and Driving Factors of Typical Open-Pit Coal Mines in Inner Mongolia.

Although coal is difficult to replace in the short term, the large-scale production and consumption of coal have significant impacts on the ecological environment. The severe disturbances, such as land excavation and occupation, that accompany the mining of mineral resources have caused dramatic changes in land cover and a significant pressure on the sensitive and fragile ecological environment. To analyze the temporal and spatial evolution trends and the differences in land use in different typical mining areas in Inner Mongolia, as well as the evaluation system and driving mechanisms of land use evolution, this study takes the typical open-pit coal mines in Inner Mongolia as the research objects and, based on the Google Earth Engine (GEE) platform, analyzes the dynamic evolution characteristics and driving factors of land use in typical open-pit coal mines in Inner Mongolia from 2001 to 2020. The change trend of land use in typical open-pit mining areas in Inner Mongolia for the past 20 years is obvious, with the highest fluctuations for grassland, mining land, cropland, and residential/industrial land. Land use in the open-pit coal mining area is greatly affected by mining factors. From the perspective of spatial variation, the most important driving factor is the distance from national roads and railways, followed by the annual average temperature and annual average precipitation and topographical conditions, such as elevation. In terms of policy, land reclamation and ecological restoration in mining areas have a positive impact on land use change. Improving the mechanism for environmental compensation in mining areas can promote the efficient and rational use of mining areas and the protection of ecosystems.

Cardiac rehabilitation knowledge in patients with coronary heart disease in Baoding city of China: A cross-sectional study.

OBJECTIVE: The purpose of this study is to assess the awareness on cardiac rehabilitation (CR) in patients with coronary heart disease (CHD). METHODS: Inpatients diagnosed with coronary heart disease were recruited from 3 hospitals in this study. The study employed a cardiac structured questionnaire to assess respondents' level of awareness, and bivariate to analyze the sociodemographic factors that influence the awareness on CR. RESULTS: Of all 500 participants, 66.40% were male and the mean age was 62.51  ±  9.96 years. The mean score of knowledge was 44.00  ±  17.00 (score range: 0-93), and the mean level of awareness was 47.31% (awareness range: 0-100%). The highest mean level of awareness was in the reexamination subscale (98%) and the lower were in the basic information about CR program, SP optimized medication and heart rate subscale. Bivariate analysis showed that higher age was associated with less knowledge. Patients with higher education level and better income status had better knowledge. And patients who lived in rural and had no jobs had less knowledge. CONCLUSIONS: This study showed low levels of awareness on CR program in CHD patients in Baoding. Therefore, the need for health education is indicated in this study to improve the awareness on CR among CHD patients.
