“90后”大学生思政课教学新思路探析——以宁夏师范学院为例

＂90后＂大学生群体具有坚定的政治信仰、强烈的爱国热情、明确的价值取向;生活态度总体上积极健康,人生目标明确。但是由于各方面原因,这一群体对未来充满了不确定感,紧张、压抑、焦虑的情绪比较严重,如果不能妥善引导和疏通,情况堪忧。高校思政理论课在解决这些问题上发挥着重要作用。因此,思政课应从构建和谐师生关系和创新教学方法等方面,提高其教学实效性。     

The role of eviction in veterans’ homelessness recidivism*

Eviction is one of the leading causes of homelessness in the U.S.A. Though permanent supportive housing (PSH) helps participants maintain housing, some still leave due to eviction. This study aimed to determine whether eviction is an important predictor of recidivism and time to return to homelessness for participants exiting PSH. The characteristics and post-exit service use of 2802 Veteran PSH participants were analyzed based on exit reason. A Cox proportional hazards survival analysis modeled risk factors for returning to homelessness within 360 days of exit. Compared with other exiters, evicted Veterans remained in the program for less time, were less likely to be receiving service-connected compensation, and used more services – particularly mental health and substance use services – following their exit, and those who returned to homelessness did so more quickly. Identifying participants who might benefit from more intensive services, project-based housing, or income supports may prevent evictions and subsequent returns to homelessness.     

单片机控制器在卷染机中的应用

】将卷染机的控制系统从直流电机拖动、自耦调压器有级调速改造为交流电机拖动和变频器无级调速。通过对调节对象的理论分析,得到了一种新的控制策略,研制出以单片机为核心的控制器,在不使用速度和张力传感器的条件下,控制系统可自动对被染织物进行恒速与恒张力控制,以利于染色质量的稳定和提高。经实际运行表明,该系统运行可靠,节能增效显著。     

韦伯论人与社会的关系

韦伯认为人是社会存在物,是理性存在与非理性存在的统一,是目的理性和价值理性的载体。在此人性论基础上,韦伯诠释了人与社会之间的互动性。这种互动性体现在:人是社会行动的主体,人通过价值观念和社会行动影响社会;社会是人存在的“场”,社会通过秩序影响人的价值观念和自由。文章认为韦伯的观点既有合理之处,也有不合理之处。     

论机动车交通事故民事赔偿责任革新：填补性到惩罚性

机动车交通事故民事赔偿一贯采取的填补性赔偿,是对机动车交通事故主观因素与客观因素考虑欠妥的结果。主观因素方面,机动车交通事故应当区分当事人的过错程度,即区分故意与过失、一般过失与重大过失。在归责原则上应全面坚持过错责任原则,符合个人就自身行为所肇致的损害应负赔偿责任的基本观念。客观因素方面,机动车交通事故损害不应固守类型化区分,而应进行程度化区分,即轻微损害、一般损害、重大损害。主观因素与客观因素相结合,机动车交通事故责任中应当引入惩罚性赔偿,搭建填补性与惩罚性结合的赔偿架构。     

感应电机的智能控制及其DSP实现研究

在分析感应电机数学模型的基础上,提出了一种基于免疫遗传算法（IGA）的递归模糊神经网络（RFNN）控制器的设计方法,并应用于交流感应电机双闭环矢量控制系统中的转速控制器中,对感应电机实现精确的速度控制。为满足控制运算实时性的要求,采用高速数字信号处理器（DSP）作为速度控制与运算单元,成功完成了递归模糊神经网络控制器的DSP实现。实验结果验证了该控制器的可行性。

走资源节约型可持续发展之路

我国农业生产中存在着人多地少、人增地减、国家对农业投入不足、农业劳动者科学文化素质低、生产环境恶化、生产基础设施不完善等诸多问题。这样的国情决定了我国必须走资源节约型可持续发展之路,必须对农业资源进行多目标、多层次、多环节的全方位开发利用,使经济、生态、社会三效益统一起来,取得最佳的综合效益,建立经济发展与资源环境相互协调的发展模式。     

中国农村居民消费需求影响因素分析

本文依据持久收入理论,应用计量经济模型分析了影响中国农村居民消费需求的各种因素,计算了平均消费倾向和边际消费倾向以确定收入的不同部分对农村居民消费的影响程度,并分析了非收入要素对消费需求的影响,得出中国农民消费需求主要取决于收入中的持久收入而与暂时收入关系不大的结论,而其它非收入因素的影响也不容忽视.最后提出促进农村居民消费增加的建议和措施.     

Exposure to Traffic and Risk of Hospitalization Due to Injuries

Research on the risk of motor vehicle injuries and their relationship with the amount of travel has been only partially analyzed. The few individual exposure assessments are related to very specific subsets of the driving and traveling populations. This study analyzes the relationship between kilometers traveled and hospitalization due to motor vehicle injuries. Twelve thousand three hundred and sixty nine Spanish university graduates from the Seguimiento Universidad de Navarra multipurpose cohort study were evaluated. They had not been hospitalized due to motor vehicle injuries at baseline and were followed up to eight years. Biannual questionnaires allowed for self‐reporting of kilometers traveled in motor vehicles, together with incidence of hospitalization. Covariates in the Cox regression models included age and gender and baseline use of safety belt while driving, driving a vehicle with driver‐side airbag, driving a motorcycle, and drinking and driving. There were 49,766 participant‐years with an average yearly travel of 7,828 km per person‐year. Thirty‐six subjects reported a first hospitalization event during this time. The adjusted hazard ratio per additional kilometer traveled was 1.00005 (95% confidence interval 1.000013 to 1.000086). Even the smallest of reductions in the amount of kilometers traveled (from an average of 3,250 km per year to 1,000) has a statistically significant protective effect on the likelihood of sustaining hospitalization due to motor vehicle injury (aHR 0.9, 95% CI 0.78 to 0.98). In light of current policies aimed to reduce motorized traffic due to environmental concerns, it may be appropriate to consider the additional health benefit related to reductions in injuries.
