This study aims to analyse the factors that can explain the adoption and effective use of a new e-learning system in Iraq. To achieve this, it uses a selection of factors that are present in the technology acceptance model (TAM) and the unified theory of acceptance and use of technology (UTAUT) model, and it includes three additional factors. The study hypothesises new relationships between the selected factors. Questionnaires were distributed to 300 university students in Iraq. Partial least squares-structural equation modelling (PLS-SEM) was used to analyse the data received. The findings suggest that perceived usefulness (PU), perceived ease of use (PEOU), subjective norms (SNs), information quality (IQ), system quality (SQ), technical support (TS) and self-efficacy (SE) have significant effects on behavioural intention (BI). In turn, BI and TS have significant direct effects on the actual use (AU) of e-learning systems. The factors age, gender and experience significantly moderated some of the relationships in the model. The research has several implications for policy makers, universities and the management of e-learning systems.  相似文献   

Association between psychosocial stressors with emotional and behavioral problems among children of low-income addicted families living in Brazil     

《Child abuse & neglect》2019

BackgroundChildren exposed to substance use in their families are vulnerable to multiple risk factors in their development and at increased risk for emotional and behavioral problems. The aims of the study were as follows 1) estimate the prevalence of emotional and behavioral problems among children aged 6–11 years old, living with addicted family members in a low-income urban community of São Paulo, Southeastern Brazil; 2) evaluate the children’s exposure to family psychosocial stressors and substance use; and 3) investigate the factors related to the increased risk of emotional and behavioral problems and substance use.MethodsA cross-sectional study was conducted among 101 children aged 6–11 years old (M = 9.16 years, SD = 1.61). The instruments used were a sociodemographic questionnaire, the Child Behavior Checklist (CBCL) and the Psychosocial Stress Factors (PSF).ResultsHigh prevalence of problems was found for this sample: the CBCL showed 26.7% of clinical scores for Internalizing Problems, 40.6% for Externalizing Problems, and 40.6% for Total Problems. Exposure to family psychosocial stressors was also high, including severe disease (33%), physical aggression (28.9%), death (27.8%), psychiatric hospitalization (16.7%), suicide attempts (15.5%), and suicide (9.3%). Exposure to these family stressors was associated with an increase of two to four times in the prevalence of internalizing and externalizing problems.ConclusionsChildren exposed to substance abusers have more mental health problems than general population, even when compared to peers living in similar low-income areas. This is a group that should be target of a selective preventive intervention.  相似文献

船舶靠泊过程中系缆作业仿真     

代广树 《上海海事大学学报》2019,40(4):17-21

为更加准确直观地模拟船舶靠泊过程中的系缆作业,将缆绳分为两部分进行建模。对缆机滚筒上的缆绳提出缠绕算法模型,计算出缆绳随着滚筒旋转的收放速度,实现使用滚筒收放缆绳的模拟。对缆机滚筒外的缆绳建立悬链线模型,计算出缆绳在不同工况下的形状和端点处的受力情况,并根据计算出的缆绳张力是否超出安全负荷对缆绳进行破断分析。根据船舶和码头形状确定碰撞检测区域,采用基于距离场的碰撞检测方法实现缆绳与船体、缆绳与码头之间的碰撞检测。通过模拟缆绳在系缆作业过程中的形状、位置和姿态变化,实现船舶靠泊过程中系缆作业的三维可视化。  相似文献   

关于我国引入足球职业裁判制度的思考          下载免费PDF全文

何博芳 《河北体育学院学报》2019,33(4):24-28

职业裁判制度是足球职业化发展到一定阶段的必然产物，其引入将有力提升我国裁判执法水平，助推我国足球事业发展。认为，职业裁判是职业联赛健康发展的关键力量，是足球运动技术发展的客观要求，是提升足球裁判整体水平、统一集中管理的需要。目前，我国的足球裁判存在基数小、水平低、待遇低、环境差等问题。只引入足球职业裁判制度而无配套措施，可能无法解决根本矛盾；目前的国内联赛规模也还无法满足职业裁判发展需求，职业转换难度大及退休保障不足，也阻碍着我国职业足球裁判制度的实施。指出，应加快足球联赛发展，与职业裁判发展互促互进；健全体育裁判法律法规，改革职业裁判组织管理方式；建立健全职业裁判员的薪酬和退休保障体系；注重青少年裁判培养，全面提升在职裁判员业务水平。多管齐下，使足球职业裁判制度发挥更好的效果。  相似文献
