中立与集体安全——伍德罗·威尔逊国联思想的起源     

韩莉 《首都师范大学学报(社会科学版)》1998,(4)

威尔逊的国联思想产生于一战爆发后的调解外交之中.这时美国外交政策的主要特征是在保持中立的基础上对欧洲冲突实行调解.美国外交传统中的中立原则决定了威尔逊政府不准备对欧洲事务承担任何义务,但是这种调解本身又有参与解决欧洲事务的含义.这种自相矛盾的政策只能导致调解失败.在这种自相矛盾的政策中,威尔逊找到了战后国际联盟这个目标,并从泛美条约的集体安全条款找到它的基础原则.国际联盟能同时满足威尔逊既不脱离传统的孤立主义又能参与欧洲事务的双重愿望.战争形势很快迫使美国放弃中立,但是国联思想却沉淀下来成为威尔逊外交的主要目标.  相似文献

关于“一苏大”会址的选择及其他——从新编《朱德年谱》的一则记事说起     

曹春荣 《赣南师范学院学报》2009,30(1):41-45

“一苏大”会址及中华苏维埃共和国临时中央政府驻地的选择,是中共临时中央（通过苏区中央局）根据共产国际的指示和自己的苏维埃区域规划,以及反“围剿”战争的形势、赣南苏区的地理民情等各种因素,综合考虑并刻意经营的结果。所谓选择瑞金是红一方面军总部和苏区中央局进驻叶坪以后,才临时决定的说法,缺乏史料依据,且有悖于史实和常理。  相似文献

Keeping their attention: Classroom practices associated with behavioral engagement in first grade mathematics classes in China and the United States   总被引：1，自引：0，他引：1  

Xuezhao Lan  Claire Cameron Ponitz  Kevin F. Miller  Su Li  Kai Cortina  Michelle Perry  Ge Fang 《Early childhood research quarterly》2009,24(2):198-211

This study investigated variation in students’ behavioral engagement across mathematics classes in China and the United States. Student behavioral engagement was examined along with two aspects of the classroom (group size and teacher instructions given about classroom behavior). Video observational data were collected and coded over 1051 time intervals in 35-minute mathematics sessions in Chinese classrooms (n = 8) and comparable American classrooms (n = 7). Latent growth analyses revealed that overall, behavioral engagement declined over time, although the drop-off was dramatically sharper in American classrooms relative to Chinese classrooms. In addition, larger group size and the timing of teacher instructions (given before versus after the behavior) were significantly associated with increased engagement. This study revealed compelling cultural differences as well as patterns in student and teacher behaviors associated with students engaging in on-task behaviors in the classroom. Implications for ways to promote effective classroom behavior are discussed.  相似文献

Old Perseans and the Great War: a study in the alumni of a minor public school     

Hugh Pattenden 《History of education》2018,47(5):628-643

This article will argue that the current historiography considers the ‘public school experience’ of the First World War too narrowly, and will emphasise that boys from a wide range of establishments experienced the war in a similar fashion to those at elite public schools. It will do this through a case study of the alumni of the Perse Grammar School, Cambridge. By approaching the experience of Perseans in a thematic fashion it will shed new light on how the alumni of schools just below and developing towards full public-school status were affected by the war, an area hitherto not fully explored.  相似文献   

Pre-service language teachers' development of appropriate pedagogies: A transition from insightful critiques to educational insights     

《Teaching and Teacher Education》2018

This paper examines how pre-service teachers of Portuguese developed ideas about contextually appropriate pedagogies during their practicum as well as what they perceived as the impact of their pedagogical practices on student learning. The findings suggest that teacher education models which promote conscious critical reflection and teacher agency, and provide space for trainees to engage constructively both with their peers and with students are likely to generate innovative ideas for teaching which are appropriate to the specific contexts within which trainees teach.  相似文献
