Data were collected through a questionnaire survey among 214 Wuhan University students and analyzed using hierarchical regression analysis.Findings： Perceived usefulness, perceived ease of use, and subjective norm can influence user intention to seek health information online. The urgency of problematic situations has a negative moderating effect on the relationship between perceived ease of use and user intention and the relationship between subjective norm and user intention. The severity of problematic situations has a negative moderating effect on the relationship between subjective norm and user intention.Research limitations： The respondents of the survey are limited to students in one Chinese university, so whether this study＇s results can be applied to another population or not remains to be verified. In addition, only two dimensions of problematic situations are considered in this study. Practical implications： The paper puts forward the moderating effect of problematic situations and verifies it, which is the compensation for online health information-seeking behavior research. Besides, our analyses have implications for professional design of health care systems and related consumer information searches, and improve their performance. Originality/value： Previous work has reported the effects of problematic situation on user intention to seek health information online, ignoring its influence on other factors. This empirical study extends that work to identify the influence of problematic situation when seeking intention-behavior data in two dimensions, urgency and severity.展开更多

Dual-trench confguradon consists of two trenches together, one wider trench and the other is narrow trench that extruded from the wider one. Several blowing ratios in the range （0.5：5） were investigated. The pitch-to-diameter ratio of 2.775 is used. By using the dual trench configuration, the coolant jet impacted the trench wall two times allowing increasing the spreading of coolant laterally in the trench, reducing jet velocity and jet completely covered on the surface. The results indicate that this configuration increased adiabatic effectiveness as blowing ratio increased. The spatially averaged adiabatic effectiveness reached 57.6% for at M= 2. No observed film blow-off at all blowing ratios. The adiabatic film effectiveness of dual trench case outperformed the narrow trench case, laidback fan-shaped hole, fan-shaped hole and cylinder hole at different blowing ratios.展开更多

A crossover design was employed. Each subject took part in two trials and ran an hour on a treadmill with the intensity of keeping heart rate at 148-150 min for each trial. Results showed that plasma glucose levels of subjects increased significantly (5.42±0.83 mmol/L) at 15 min after ingestion of a chocolate bar and maintained in moderate high levels (4.92 ±0.57 mmol/L) until 30 min after an hour's running while the glucose levels were low and dropped to under normal ranges (3.84 ± 0.31 mmol/L) at 30 min after exercise as they were with a supplement of placebo. Results of plasma FFA, blood lactate and plasma urea nitrogen levels and RPE all indicated that chocolate bar supplementation before exercise benefits to create the necessary prerequisite for exercise and recovery展开更多

To remedy this lacuna, the authors developed a model in which real effective exchange rate moderated the effect of import and utilization of foreign capital on export. The sample comprised 11 years＇ data in Guangdong China. The result showed that real effective exchange rate of RMB affected the export by interacting with utilization of foreign capital. Moreover, to some degree, the real effective exchange rate can also act as moderator between import and export.展开更多

文摘BACKGROUND Adolescence is a period marked by physiological and psychological imbalances,which pose an increased risk for adolescents with major depressive disorder(MDD)to commit non-suicidal self-injury(NSSI).AIM To investigate the moderating role of social support utilization in depression and NSSI among adolescents with MDD.METHODS This cross-sectional study enrolled 314 adolescents with MDD(258 with NSSI,56 without)from a Chinese tertiary psychiatric hospital(2021-2023).Participants completed validated scales,including the self-esteem scale,the Barratt impulsiveness scale,the self-rating depression scale,and the teenager social support rating scale.Logistic regression and hierarchical regression analyses were used to examine predictors of NSSI and the moderating effect of social support utilization.RESULTS Results showed that the NSSI group had higher depression levels,lower selfesteem,and greater impulsivity.While overall social support was higher in the NSSI group,social support utilization significantly moderated the depression-NSSI relationship.Specifically,higher utilization levels weakened the association between depression and NSSI(β=-0.001,P<0.05).CONCLUSION These findings suggest that effective utilization of social support,rather than its mere presence,is crucial in reducing NSSI risk among depressed adolescents.
文摘Estimated at more than 2.2 million cases worldwide,most breast cancer cases and deaths from breast cancer occur in low and middle-income countries.In Cameroon,many studies have underlined the effect of knowledge of breast cancer on screening measures such as self-examination and,to a lesser extent,the perception of the threat of this disease.This research aims to assess according to the Health Belief Model(HBM),the moderating effect of perceived threat of breast cancer on the relation between knowledge and breast self-examination.A questionnaire survey was conducted among 517 Cameroonian women to assess their general knowledge about breast cancer(risk factors and screening measures),their level of the perceived threat of breast cancer through Perceived susceptibility and severity,and the prevalence of breast self-examination amongst them.A regression analysis using the Macro Process for moderation indicates the main effect of Perceived threat(b=0,29;t(517)=2,36;p=0,02)of breast cancer and knowledge(b=0,02;t(517)=4,29;p<0,001)on breast self-examination.Results also confirm that the perceived threat of breast cancer moderates the effect of knowledge on breast self-examination.While the low level of perceived threat highlights the effect of knowledge on breast self-examination(b=0,02;t(517)=3,49;p<0,001),the high level of perceived threat cancels that effect(b=0,01;t(517)=1,97;p=0,01).A woman who perceives severity and susceptibility to breast cancer is more inclined to perform breast self-examination.This result suggests the importance of taking into account,in a context where knowledge of breast cancer is limited,relevant factors of the health belief model in preventive measures against breast cancer in general and the practice of breast self-examination in particular.

文摘In this work,we report a novel octa-nuclear uranyl(U8)motif[(UO2)8O4(μ3-OH)2(μ2-OH)2]4+embedded in a uranyl-oxalate coordination polymer(compound 1)based on a U-shaped linker with extra-long xylylene chains for stabilizing the resulting high-nuclear motif through additional cross-linking connectivity.A comparison with dimeric and monomeric uranyl compounds obtained at different pH value from the same hydrothermal system reveals that,solution pH plays a vital role in formation of this octa-nuclear uranyl motif by promoting hydrolysis of uranyl source.Since high similarity of eight uranium centers in this nearly planar U8 motif here,overlapping and broadening of signals in fluorescence,infra-red(IR)and Raman spectra can be found.

文摘In the present work, computational simulations was made using ANSYS CFX to predict the improvements in film cooling performance with dual trench. Dual-trench confguradon consists of two trenches together, one wider trench and the other is narrow trench that extruded from the wider one. Several blowing ratios in the range （0.5：5） were investigated. The pitch-to-diameter ratio of 2.775 is used. By using the dual trench configuration, the coolant jet impacted the trench wall two times allowing increasing the spreading of coolant laterally in the trench, reducing jet velocity and jet completely covered on the surface. The results indicate that this configuration increased adiabatic effectiveness as blowing ratio increased. The spatially averaged adiabatic effectiveness reached 57.6% for at M= 2. No observed film blow-off at all blowing ratios. The adiabatic film effectiveness of dual trench case outperformed the narrow trench case, laidback fan-shaped hole, fan-shaped hole and cylinder hole at different blowing ratios.

文摘Regulation of oxygen on properties of moderately boron-doped diamond films is fully investigated.Results show that,with adding a small amount of oxygen(oxygen-to-carbon ratio<5.0%),the crystal quality of diamond is improved,and a suppression effect of residual nitrogen is observed.With increasing ratio of O/C from 2.5%to 20.0%,the hole concentration is firstly increased then reduced.This change of hole concentration is also explained.Moreover,the results of Hall effect measurement with temperatures from 300 K to 825 K show that,with adding a small amount of oxygen,boron and oxygen complex structures(especially B_(3)O and B_(4)O)are formed and exhibit as shallow donor in diamond,which results in increase of donor concentration.With further increase of ratio of O/C,the inhibitory behaviors of oxygen on boron leads to decrease of acceptor concentration(the optical emission spectroscopy has shown that it is decreased with ratio of O/C more than 10.0%).This work demonstrates that oxygen-doping induced increasement of the crystalline and surface quality could be restored by the co-doping with oxygen.The technique could achieve boron-doped diamond films with both high quality and acceptable hole concentration,which is applicable to electronic level of usage.
文摘To study the effects of a chocolate bar supplementation before exercise on improving recovery of physiological and metabolic changes induced by exercise, 16 male students aged 18-20 years voluntarily served as subjects. A crossover design was employed. Each subject took part in two trials and ran an hour on a treadmill with the intensity of keeping heart rate at 148-150 min for each trial. Results showed that plasma glucose levels of subjects increased significantly (5.42±0.83 mmol/L) at 15 min after ingestion of a chocolate bar and maintained in moderate high levels (4.92 ±0.57 mmol/L) until 30 min after an hour's running while the glucose levels were low and dropped to under normal ranges (3.84 ± 0.31 mmol/L) at 30 min after exercise as they were with a supplement of placebo. Results of plasma FFA, blood lactate and plasma urea nitrogen levels and RPE all indicated that chocolate bar supplementation before exercise benefits to create the necessary prerequisite for exercise and recovery
文摘An important limitation of the research literatures which study the effect on the export of the real effective exchange rates is the lack of application of interaction or moderator effect among the independent variables. To remedy this lacuna, the authors developed a model in which real effective exchange rate moderated the effect of import and utilization of foreign capital on export. The sample comprised 11 years＇ data in Guangdong China. The result showed that real effective exchange rate of RMB affected the export by interacting with utilization of foreign capital. Moreover, to some degree, the real effective exchange rate can also act as moderator between import and export.
文摘Background and Objectives:This study aimed to evaluate the role of selenium intake on the correlation be-tween obesity and sex hormone levels in children and adolescents.Methods and Study Design:Children and adolescents(6-19-year-old)with complete body mass index(BMI),selenium intake,and sex hormone level data were included.Applying weighted linear regression model to analyze the relationships of obesity and selenium intake with testosterone,estradiol,and sex hormone-binding globulin(SHBG)levels.Then,interaction terms for different selenium intake levels(<Q1,≥Q1)and obesity(no,yes)were constructed,to investigate the moderating effect of selenium intake on the correlation between obesity and sex hormones.Results:A total of 3,380 partici-pants were enrolled.Although selenium intake showed no direct relationship with testosterone,estradiol,or SHBG levels in any group(p>0.05),it demonstrated a significant interaction with obesity in terms of sex hor-mone levels.In females aged less than 12 years,there was an interaction between obesity and selenium intake on testosterone levels(pinteraction=0.007).The interaction of obesity and selenium intake on SHBG levels was ob-served in both males and females(all pinteraction<0.001).Moreover,a trend was observed for the effects of these interaction terms on testosterone,estradiol and SHBG levels(all ptrend<0.05).Conclusions:Selenium intake may play a moderating effect in the relationship between obesity and sex hormones.
