Teacher burnout and frequent turnover negatively affect stability and productivity in the context of higher education. Despite the fact that the relationship between burnout and turnover intention ...has been thoroughly studied, the role of other factors in this relationship should be evaluated in order to better clarify underlying mechanisms, particularly in the context of higher education.
In this study, we first aim to bridge a research gap by utilizing job satisfaction as a mediating variable for the relationship between burnout and turnover intention. Moreover, we uniquely evaluate the role of proactive personality as a moderating variable, first in terms of the relationship between burnout and job satisfaction, and then for the relationship between job satisfaction and turnover intention. Based on 296 valid questionnaires collected from university faculty members in China, proposed hypotheses were evaluated empirically.
The results demonstrate that, as expected, burnout has a significant and positive impact on turnover intention, and job satisfaction has significantly negative impact on turnover intention, with job satisfaction partially mediating the relationship between burnout and turnover intention. Moreover, proactive personality moderated the relationship between job satisfaction and turnover intention, with this relationship being stronger for individuals with high proactive personality as compared to low proactive personality.
These findings provide a better understanding of the relationship between burnout and turnover intention of university instructors. Theoretical and practical implications, limitations, and recommendations for further research are provided.

•Fungus was used as a template for the assembly of CNTs.•Fungal template enhanced the dispersity and stability of CNTs.•FH/CNTs exhibited high sorption capacity for U(VI) (187.26 mg/g), MV ...(43.99 mg/g) and CR (20.89 mg/g).•FH/CNTs possessed satisfactory regeneration performance and reusability.•FH/CNTs has a good selectivity on U(VI).
In this paper, a biological assembly method was used to fix carbon nanotubes (CNTs) onto fungal hyphae (FH) to prepare sphere FH/CNTs composite as a versatile adsorbent for water pollution control. Physico-chemical characterization results showed that FH/CNTs composites had a wire stacking surface morphology, showed a typical diffraction peak of CNTs, was rich in functional groups, and was negatively charged under pH 3 to 10. Adsorptions of uranium (U(VI)), anionic (Congo red (CR)) and cationic (methyl violet (MV)) dyes under various conditions were investigated to elucidate their adsorption performances and mechanisms. Results showed that the composites could efficiently remove U(VI)), CR and MV from solutions. For example, the maximum adsorption amounts of FH/CNTs composites for U(VI), CR and MV reached 187.26, 43.99 and 20.89 mg/g, respectively. The adsorption process was fitted better by pseudo-second order model, while both of Langmuir and Freunlich models were well fitted to the adsorption isotherms for these pollutants. Moreover, the composites could be easily separated after adsorption and efficiently reused. Thus FH was an efficient platform for the assembly of CNTs, and the as-prepared FH/CNTs composites had the potential application in water pollution control.
Abstract
This study locates as its focus the site for the final item in a sentence-in-progress as a late but systematic
opportunity space for co-completing sentences by another speaker, and as a ...systematic site for brief overlaps. A second speaker
may supply a version of the final item as projected by the grammatical structure of the sentence-so-far in given contexts to offer
assistance for the searched-for final item upon the current speaker’s displayed delivery trouble, or to show an early recognition
of what the current turn is doing and what it takes for its completion in the absence of any display of delivery trouble. The
overlap in the first case may be ‘accidental’ when the first speaker is able to produce his/her own final item a moment later, or
it may be an ‘achieved’ early start in the second case. The same opportunity space may also be ‘exploited’. Final items proposed
by the second speaker may generate a local sequence where its acceptability becomes relevant. Post-overlap responses by the first
speaker often show acceptance, sometimes with qualification. We argue that overlapping final-item completion is a result of
speakers’ active participation and high involvement, and is motivated by the fundamental baseline of cooperation and collaboration
in human social interaction.
Inspired by microbial diagenesis and mounding, microbial mineralization technology has been widely used in the treatment of heavy metal and radionuclide contamination. S. pasteurii can decompose urea ...as a source of energy to produce CO32− in the microbial mineralization system. Therefore, strontium-contaminated radioactive wastewater can be effectively treated by combining CO32− with surrounding strontium ions (Sr2+) to form strontium carbonate (SrCO3). Herein, we investigated how the concentration of graphene oxide (GO) and mineralization time influence the morphology of SrCO3 and the mineralization efficiency. GO was used as a crystal regulator to solidify the radionuclide strontium in the microbial mineralization system to obtain large-scale rock-like SrCO3 minerals. The results showed that GO can adsorb the surrounding Sr2+ with oxygen-containing functional groups on its surface to form SrCO3 complexes, directly influencing the morphology and consolidation percentage of SrCO3. Considering the leaching behaviour of nuclides, we further studied the stability of consolidated SrCO3 minerals. The results indicated that the presence of GO improved the stability of the mineralized samples obtained in the microbial mineralization system.
•Propose a new strategy for microbial solidification of strontium.•Mineralization of strontium can be realized in a wide range.•The presence of GO stabilizes the large-scale rock-like SrCO3 minerals.
Influenced by a number of uncertain factors, Unemployment rate of college graduates has characteristics of stochastic nature and fluctuations. Single gray GM (1,1)model could not fit these data ...better, and its forecasting accuracy is lower. However, Markov forecast can make up for this deficiency. Drawing on the virtue of gray model and Markov forecasting model, this paper presents a grey-Markov forecasting model for forecasting unemployment rate of graduates in China. This method takes into account the general trend series and random fluctuations about this trend. It has the merits of both simplicity of application and high forecasting precision. This paper is on basis of historical data of the unemployment rate of graduates in China, and forecasts and analyzes the unemployment rate of graduates in China in terms of grey-Markov forecasting model.
This study proposes an algorithm for maximizing strip width in orthogonal turn-milling based on variable eccentric distance. The machining error model is first established based on the local cutting ...profile at the contact line. The influencing factors of the strip width are then investigated to analyze their features and determine an optimizing strategy. The optimized model for maximum machining strip width is formulated by adopting a variable eccentric distance. Hausdorff distance and Fréchet distance are introduced in this study to implement the constraint function of the machining error in the optimized model. The computing procedure is subsequently provided. Simulations and experiments have been conducted to verify the effectiveness of the proposed algorithm.
Suicide rates in rural China are two-fold to three-fold those in urban China but the reasons for this large difference remain unclear.
Assess the characteristics and risk factors of medically serious ...suicide attempts in rural China.
A comprehensive 2 to 3 hour structured interview was administered by psychiatrists to 297 medically serious suicide attempters (defined as those who remained in hospital for 6 hours or longer) treated in the emergency room of the People's Hospital of Yuncheng County in Shandong Province and, separately, to their accompanying co-resident family members. A parallel interview was administered to control subjects matched for age and gender from the same village who had never made a suicide attempt and to their co-resident family members. Risk factors for attempted suicide were identified using Cox regression models.
Among the 297 suicide attempters, 74% were female, 78% were farmers, their mean (sd) age was 33.2 (14.6) years, their mean length of formal schooling was 4.8 (3.1) years, 80% had attempted suicide by ingesting pesticides, 57% reported considering suicide for five minutes or less before acting, 76% had a score of less than 50 (range, 0 to 100) on the planning subscale of the Suicide Intent Scale, 11% had made prior attempts, and only 38% met DSM-IV criteria for a current mental disorder. After controlling for gender, age, location of residence and prior suicide attempt (in the matched analysis), risk factors identified in the multivariate analysis included a low level of education, having relatives or associates with prior suicidal behavior, experiencing four or more negative life events in the prior year, a low quality of life and low family cohesion over the prior month, high depressive symptom scores over the prior two weeks, and (only assessed in a subsample) high impulsivity and aggression.
Many of the medically treated suicide attempts in rural China are low-intent attempts by the ingestion of pesticides in persons who do not meet criteria of a mental disorder but have high levels of impulsiveness and aggression. This profile is different from that seen in high-income countries so it will require a different approach to the prevention of suicidal behavior, an approach that is less focused on the identification and treatment of mental disorders and more focused on limiting access to agricultural poisons and training impulsive individuals about self-regulation of their emotions and behaviors.
