中国“碳中和”目标的实现路径与模式选择

围绕中国碳中和目标的实现路径与模式选择问题，提出了一个中国应对气候变化整体治理模式，即多阶段混合主导型碳中和实现模式。这一模式是以国家为核心，在一定时期和内外环境约束下，通过减排和增汇路径，对中国境内由人类活动造成的CO2排放与人为CO2吸收量之间关系进行调整和平衡的过程；其内部由宏观、中观和微观三层结构组成，每层结构各不相同。多阶段混合主导型碳中和实现模式的提出，拓展和完善了气候变化整体治理理论，为气候变化治理提供了机制借鉴。     

高校德育低效的内因分析

高校德育低效除社会大环境的负面影响外,高校德育自身的问题也不可忽视。智德分离;不尊重学生的主体地位;忽视培育和发展学生的情感、忽视学生的差异和个性;德育与学生的生活和需要脱节;育德者的人格不适应德育的要求等德育自身的缺陷是德育低效的内在原因。     

福柯的自我建构理论及其教育意义

在当前对福柯理论所进行的探讨中,我们对福柯的诸如权力/知识、话语等理论给予了很多的关注,却很少关注福柯的自我建构理论及其所具有的意义.因此,本文立足于福柯的自我建构理论,通过对自我建构所运用的技术,来指出自我建构理论的实质内涵,以及其深层次下权力/知识、话语的作用,以此来认识自我建构的理论所具有的教育内涵,它对教育所产生的影响,最后对这种理论进行简要的评价.

高精度渗碳控制方法

在采用电阻法直接测控碳势的方法中,提出了一种分段参数调节增量式PID算法,通过实际调试和理论推导表明,渗碳工艺过程控制具有控制超调量小、过渡时间短、精度高、软件实现方便等优点,稳定后碳势控制精度可达±0.03%。     

1000VMOSFET用常规低压工艺的实现

采用常规低压集成电路工艺实现了耐压达１０００Ｖ的高压横向ＭＯＳＦＥＴ，详细介绍了该高压横向ＭＯＳＦＥＴ的设计方法、器件结构、工艺技术及测试结果。文中从实验和分析的角度上首次探讨了覆盖在漂移区上面的金属栅长度对该高压横向ＭＯＳＦＴ击穿电压的影响。     

Attracting Micro‐Enterprises To Learning

Micro‐enterprises, i.e. firms with less than 10 employees, are traditionally the hardest to engage in learning; they are also least likely to participate in such measures as business advice and guidance provision and initiatives to support information communication technology (ICT) adoption. Through a community‐based initiative initially targeting parents (unemployed or employed) to participate in ICT, 30 micro‐enterprises were attracted to learning for the first time. These companies had carefully avoided similar initiatives taking place locally, which emphasized business success and growth; they had only participated in this ICT skills training because of their children. The paper takes a case study approach to evaluate the reasons for participation, explores barriers and implications for those organizing similar activities, and calls for a more holistic view of owners and managers of small firms as fathers, mothers, etc. rather than just as ‘entrepreneurs’.     

低层次产业对智力的挤出效应

低层次产业对解决低技术劳动力就业有益，但对智力资源扣科教基本设施却会带来损害。本文探讨产业发展和教育发展的关系．着重探讨低层次产业对智力资源和设施的国际挤出效应，地区挤出效应和本地挤出效应。本文同时指出低层次产业尽管对智力存在负面效应，但不应该因此否定它，并且提出在我国产业布局和地方经济发展中应遵循梯度转移的规律，谨防欠发达区低层次产业发展对智力挤出的同时对收入也形成挤出，谨防发达区因为产业层次不高对智力形成挤出．谨防欠发达区盲目发展高层次产业对低技术劳动力形成驱赶等政策建议。     

Who Gets What From Government? Distributional Consequences of Child‐Care Assistance Policies

Given the fragmented structure of child‐care assistance in the United States, it has been difficult to obtain accurate estimates of which families are assisted, through which mechanisms, and at what level. Making use of survey data from New York City, we analyze the distribution of several forms of public child‐care assistance. Results suggest that about 40% of all families with young children receive some form of child‐care assistance. Considering all forms of assistance, the distribution of child‐care help is targeted in both expected and some unexpected ways. Implications of these results are discussed in the context of U.S. child‐care policies governing access and benefit levels.     

板栗干枯病的低温防治初探

在冬季低温条件下,用40%腐烂敌80倍液及其它药剂对板栗干枯病进行病部涂抹防治,用白色塑料薄膜包严。调查不同处理时期的防治效果发现,以11月22日腐烂敌处理效果最佳,病部复发率最低(为零),为板栗干枯病的有效防治提供了科学依据。
