完善内部会计控制制度发挥财务管理作用

内部会计控制工作是实施会计监督的基本环节与基本手段,随着市场经济的发展和卫生体制改革的不断深入,完善内部会计控制工作更为重要。只有把内部会计控制工作与改善经营管理、建立现代模式的医院管理制度相结合,使整体会计工作水平稳步提高,会计工作才能在医院经营管理中发挥重要作用,使医院走向良性循环、健康持久的发展之路。     

制约机制在教育管理中的应用

制约机制是教育管理机制的重要组成部分,促进社会组织中的各个组成部分或各管理环节相互作用、合理制约,从而使系统中有形要素或无形要素按照其内在规律在运动中相互联系、相互结合形成特定功能,促进教育管理的健康发展。     

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

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.     

知识存取：内涵、特征及其量素

论述图书馆的本质特征是知识存取。知识存取具有系统性、动态性、增值性特征。知识存量是知识增长的静态表征,是系统在特定时点的知识储备水平,反映知识的组织状况和供应能力;知识取量是知识的动态表征,是系统在特定时段的知识流动总量,反映知识的扩散速度和水平;知识质量是知识内在质的规定性,是系统知识现实与潜在价值的总和,反映知识的直接效用和耐用程度;知识变量是知识在存取中的变化值,是系统知识的变化总量,反映知识在存取中转化的程度。知识存取,正是要努力地实现客观知识朝着理想的增函数曲线方向变化。     

天然水中碳酸测定有关问题的探讨

介绍了天然水体中碳酸的来源、存在形式及平衡关系；指出用“双指示剂”法测定水中碱度的第一终点应显粉紫色，第二终点宜采用甲基红一溴甲酚绿混合指示剂；测定游离二氧化碳要用双样测定并严格控制滴定终点；各种碳酸的含量可与pH值、硬度的测定结果进行校核。     

清季四川南部县乡约考述——基于清代《南部县档案》为中心的考察

以往的乡约研究大多偏重＂论＂,相关历史事实的铺陈却不甚清晰。鉴于此,本文以清代《南部县档案》为主要参考资料,对该县乡约的设置、职能、任充与辞革、点卯等诸多史实进行了重新建构,期望能为研究者提供经初步逻辑梳理后的历史素材。     

Novel mathematical model to estimate ball impact force in soccer

To assess ball impact force during soccer kicking is important to quantify from both performance and chronic injury prevention perspectives. We aimed to verify the appropriateness of previous models used to estimate ball impact force and to propose an improved model to better capture the time history of ball impact force. A soccer ball was fired directly onto a force platform (10 kHz) at five realistic kicking ball velocities and ball behaviour was captured by a high-speed camera (5,000 Hz). The time history of ball impact force was estimated using three existing models and two new models. A new mathematical model that took into account a rapid change in ball surface area and heterogeneous ball deformation showed a distinctive advantage to estimate the peak forces and its occurrence times and to reproduce time history of ball impact forces more precisely, thereby reinforcing the possible mechanics of ‘footballer’s ankle’. Ball impact time was also systematically shortened when ball velocity increases in contrast to practical understanding for producing faster ball velocity, however, the aspect of ball contact time must be considered carefully from practical point of view.     

新生入学报到条码扫描式管理平台（网络版）的设计与实践

随着高校入学新生数量的增多,同时新生报到过程中要涉及到学校的许多部门,这就给掌握新生报到情况带来了数据不准、流程不规范的问题,严重时将导致不能准确掌握未报到的学生情况,致使不能够及时对这些考生退档,为了解决这一问题,经过详细调研,同时经过使用,认为采用SQLSERVER实现的《新生入学报到条码扫描式管理平台》(网络版)可以很好的解决这一问题。
