Abstract

BackgroundDue to the prominent particularity of medical work， nurses are prone to developing depression， which not only poses a considerable threat to the physical and mental health of nurses， but also affects the quality of nursing to some extent. Occupational stress is a known contributor to depression in nurses， whereas relatively little research has been done to investigate the underlying mediation path.ObjectiveTo explore the mediation effect of perceived organizational support and psychological capital on the relationship between occupational stress and depression among nurses， and to provide theoretical references for the prevention and treatment of occupational stress-induced depression in nurses.MethodsFrom March to August 2019， a stratified random sampling method was utilized to select a sample size of 720 nurses in each department of a grade A tertiary hospital in Shandong Province. All subjects were assessed using Effort-Reward Imbalance Questionnaire （ERI）， Perceived Organization Support Questionnaire （POS）， Psychological Capital Questionnaire （PCQ） and Center for Epidemiologic Studies Depression Scale （CES-D）. Pearson correlation was adopted to examine the correlation among above scales， and multilevel mediation analyses were conducted with model 6 in Process macro （version 3.3） for SPSS 26.0 using Bootstrap re-sampling method.ResultsA total of 658 nurses （91.39%） completed the effective questionnaire survey. ERI score was positively correlated with CES-D score （r=0.499， P

Abstract

[Objective] In order to explore the changes of vegetation communities under different grazing intensities in grassland, the effects of community characteristics on soil aggregates were analyzed. [Methods] Taking the controlled grazing experimental area of Xilamuren desert steppe as the research object, the characteristics of vegetation community and soil aggregates under light grazing (LG), moderate grazing (MG), heavy grazing (HG), and no grazing (CK) and their relationship were analyzed by field investigation and indoor analysis, and the effects of plant community changes on soil aggregates were revealed. [Results] (1) The Shannon-Wiener diversity index (H′) and Simpson dominance index (D) of LG were significantly lower than those of other grazing intensities (p

Abstract

In order to accurately predict the total organic carbon content of Middle Permian taodonggou group source rocks in Turpan Hami basin, based on the analysis of the relationship between logging parameters of multiple wells and organic matter abundance in the study area, the generalized Δlog R model is extended, that is, a generalized Δlog R model with spontaneous potential is proposed. It is found that the source rock in the study area has a weak positive correlation with resistivity density, a weak negative correlation with spontaneous potential, spontaneous gamma and density, and little correlation with neutrons. Compared with other methods, the correlation coefficient (R2) of the generalized Δlog R model with spontaneous potential is 0.804 2 and the average error rate is 15.58 %, which is the best method to predict the total organic carbon content of the source rocks of the Middle Permian Taodonggou group in the area. The results provide a basis for logging evaluation of source rocks in the study area.
