Impact of self-directed learning readiness and learning attitude on problem-solving ability among Chinese undergraduate nursing students

Objective: To explore the effects of self-directed learning readiness and learning attitude on problem-solving ability among Chinese undergraduate nursing students. Methods: A convenience sampling of 460 undergraduate nursing students was surveyed in Tianjin, China. Students who participated in the study completed a questionnaire that included social demographic questionnaire, Self-directed Learning Readiness Scale, Attitude to Learning Scale, and Social Problem-Solving Inventory. Pearson’s correlation analysis was performed to test the correlations among problem-solving ability, self-directed learning readiness, and learning attitude. Hierarchical linear regression analyses were performed to explore the mediating role of learning attitude. Results: The results showed that learning attitude (r=0.338, P<0.01) and self-directed learning readiness (r=0.493, P<0.01) were positively correlated with problem-solving ability. Learning attitude played a partial intermediary role between self-directed learning readiness and problem-solving ability (F=74.227, P<0.01). Conclusions: It is concluded that nursing educators should pay attention on students’ individual differences and take proper actions to inspire students’ self-directed learning readiness and learning attitude.

Role of academic self-efficacy in the relationship between self-directed learning readiness and problem-solving ability among nursing students

Objective: Problem-solving should be a fundamental component of nursing education because It is a core ability for professional nurses. For more effective learning, nursing students must understand the relationship between self-directed learning readiness and problem-solving ability. The aim of this study was to investigate the relationships among self-directed learning readiness, problemsolving ability, and academic self-efficacy among undergraduate nursing students.Methods: From November to December 2016, research was conducted among 500 nursing undergraduate students in Tianjin, China,using a self-directed learning readiness scale, an academic self-efficacy scale, a questionnaire related to problem-solving, and selfdesigned demographics. The response rate was 85.8%.Results: For Chinese nursing students, self-directed learning readiness and academic self-efficacy reached a medium-to-high level,while problem-solving abilities were at a low level. There were significant positive correlations among the students' self-directed learning readiness, academic self-efficacy, and problem-solving ability. Furthermore, academic self-efficacy demonstrated a mediating effect on the relationship between the students' self-directed learning readiness and problem-solving ability.Conclusions: To enhance students' problem-solving ability, nursing educators should pay more attention to the positive impact of self-directed learning readiness and self-efficacy in nursing students' education.

Water oxidation catalytic ability of polypyridine complex containing a μ-OH, μ-O_2 dicobalt(iii) core

Two polypyridine complexes containingμ‐OH,μ‐O2dicobalt(III)cores,[(TPA)CoIII(μ‐OH)(μ‐O2)CoIII(TPA)](ClO4)3and[(BPMEN)CoIII(μ‐OH)(μ‐O2)CoIII(BPMEN)](ClO4)3(TPA=tris(2‐pyridylmethyl)amine,BPMEN=N,N′‐dimethyl‐N,N′‐bis(pyridin‐2‐ylmethyl)ethane‐1,2‐diamine),have previously been reported as inactive in the light‐driven water oxidation reaction(ACS Catal.,2016,6,5062?5068).Herein,another dicobalt(III)compound,μ‐OH,μ‐O2‐[{(enN4)2Co2}](ClO4)3(enN4=1,6‐bis(2‐pyridyl‐2,5‐diazaocta‐2,6‐diene),with a similar core structure was synthesized,characterized,and applied to the light‐driven water oxidation reaction.Collective experiments showed that the complex itself was also inactive in the light‐driven water oxidation,and that the activity observed originated from Co(II)impurities.This research establishes that complexes possessing aμ‐OH,μ‐O2dicobalt(III)core structure are not appropriate choices for true molecular catalysts ofwater oxidation.

Evolution of soil DOM during thermal remediation below 100℃:concentration,spectral characteristics and complexation ability

The impact of thermal remediation on soil function has drawn increasing attention.So far,as the most active fraction of soil organic matter,the evolution of dissolved organic matter(DOM)during the thermal remediation lacks in-depth investigation,especially for the temperatures value below 100℃.In this study,a series of soil thermal treatment experiments was conducted at 30,60,and 90℃ during a 90-d period,where soil DOM concentration increased with heating temperature and duration.The molecular weight,functional groups content and aromaticity of DOM all decreased during the thermal treatment.The excitation-emission matrices(EEM)results suggested that humic acid-like substances transformed into fulvic acid-like substances(FIII/FV increased from 0.27 to 0.44)during the heating process,and five DOM components were further identified by EEM-PARAFAC.The change of DOM structures and components indicated the decline of DOM stability and hydrophilicity,and can potentially change the bioavailability and mobility.Elevated temperature also resulted in the decline of DOM complexation ability,which may be caused by the loss of binding sites due to the decrease of polar function groups,aromatic structures and hydrophilic components.This study provides valuable information about the evolution of DOM during thermal remediation,which would potentially change the fate of metal ions and the effectiveness of the post-treatment technologies in the treated region.

家庭养老能力评价指标体系构建与实证分析

家庭养老能力事关社会养老服务需求与发展,亟需构建科学有效的家庭养老能力评价指标体系。文章利用CHARLS2018年调查数据,构建出由自我养老能力、配偶养老能力和子女养老能力组成的3个准则指标,共有9个子准则指标和17个观测指标构成的家庭养老能力综合评价指标体系。采用熵权法和复相关系数法确定指标权重,并运用U检验、H检验和空间相关性分析家庭养老能力及其分维度的分布特征。结果显示:子女养老能力、自我养老能力和配偶养老能力权重系数分别为0.555、0.288和0.157。家庭养老能力的得分为0.433±0.091,子女养老能力、自我养老能力和配偶养老能力分维度得分分别为0.121±0.056、0.066±0.019和0.245±0.069,均呈现右偏分布,子女养老能力维度失分最多,自我养老能力维度差异性最大。女性、农村和西部地区老人的家庭养老能力显著弱于男性、城市和东部地区老人。低龄老人自我养老能力和配偶养老能力显著较高,但子女养老能力也显著低于高龄老人。中国家庭养老能力居前三位的是上海市、北京市和新疆维吾尔自治区,云南省、甘肃省和安徽省居后三位。研究发现中国家庭养老能力总体得分不高,自我养老能力与子女养老能力之间呈现“互补”态势。家庭养老能力分布呈现性别、城乡和区域差异性。养老服务体系需基于当前家庭养老能力及其分维度的地区差异性,因地制宜发展。

酸岩反应过程模拟实验及残酸离子变化规律——以大庆油田为例

酸岩反应复杂,反应过程中会产生大量离子,可能随着pH值升高生成二次沉淀,从而影响酸化效果,因此分析酸岩反应过程中离子变化规律是酸化配方的技术关键。选取盐酸、土酸与大庆油田储层岩屑模拟酸岩反应,通过反应后酸液pH值梯次调控,模拟油层条件下酸岩反应进程及离子浓度变化规律。结果表明,pH值调节过程稀释倍数对残酸中金属离子浓度变化影响小,可不做考虑,放置时间以6 h为最佳;Ca^(2+)、Fe^(3+)、Al^(3+)是盐酸残酸产生二次沉淀的主要离子,Ca^(2+)、Fe^(3+)、Al^(3+)、Si^(4+)是土酸残酸产生二次沉淀的主要离子。在对酸岩反应机理及二次沉淀产生原因分析的基础上,自主研发了能减少酸岩反应二次沉淀的酸液——高络合酸,通过将高络合酸与土酸残酸进行定量对比和评价,验证了高络合酸具有抑制二次沉淀生成的效果,为提高酸化效果提供了新的思路。

足踝复合体本体感觉的测量与评价

背景:足踝本体感觉的研究对于慢性踝关节不稳、老年疾病的康复治疗以及身体姿势控制、运动表现的提高至关重要。前期的相关研究经常把足部和踝关节的感觉评价分开研究,对全面且综合地了解其感觉功能存在一定的局限。目的:足踝复合体是唯一与支撑面直接接触的部位,在收集体感反馈和调节平衡控制中起重要作用。文章通过汇总现有关于足部和踝关节本体感觉的调查研究,梳理足踝复合体感觉的测量与评价方法,以期为日后的相关研究做出铺垫并提供理论依据。方法:中文检索词为“(足OR足踝关节OR踝关节)AND(感觉OR本体感觉)”、英文检索词为“(foot OR ankle)AND(feel OR proprioception)”,在Web of Science、PubMed和中国知网数据库检索相关文献,了解关于足踝基本概念、研究现状与范畴,总结并评价足踝的本体感觉评价方法,最终纳入57篇文献进行综述分析。结果与结论:①足踝复合体感觉的评价主要分为对足部的感觉评价和踝关节的本体感觉评价。②足部的感觉评价主要描述其皮肤的感觉以及干预条件下的感觉反馈,方法主要包括:压力感觉阈值测试、足(底侧和跖侧)两点辨别能力测试、皮肤振动感觉持续时间测试。③踝关节本体感觉评价着重描述关节位置、运动范围、力值及功能表现,方法主要分为静态的关节角度重置测试、运动最小阈值测试、力觉重现测试以及动静态的平衡、速度及行走能力的测试。④对量化结果的报道一般以“误差”来表示,根据报道的需要一般分为:绝对误差、相对误差和恒定误差等。⑤结果证实,足踝复合体具备特殊的感觉能力,包括足部感觉和踝关节的本体感觉,影响人类的生活质量以及运动表现;足部感觉与踝关节本体感觉的弱化均与人体平衡能力下降相关,二者联合测量可以全面有效地评价足踝功能;根据不同的研究需求,需要选择足部与踝关节的感觉测量方法的组合形式,并充分考虑环境、情绪以及报道方式等多种影响因素,提高测量与评价的有效性。
