JIANGYouyi TANMingshu LIUXuefei 《重庆大学学报(英文版)》2004,3(1):105-107

This work deals with the power exponent r1 and r2 respectively of the maximal and second-maximal prime factors ofthe order of simple K4-group, and the classification for simple {5,7}′-K4-group G (i.e. ｜G｜ can not be divided by 5 nor by 7 or ｜π(G)｜ = 4 ), simple 5′ -K4-group G (i.e. ｜G｜ can not divided by 5 and ｜π(G)｜ =4) and simple 7′-Ea-group G (i.e. ｜G｜ can notdivided by 7 and ｜π(G)｜ =4). It is derived that r1 =1, 2 and 4, and r2 is not greater than 4. All the simple K4-groups with order 2^a3^b5^cp^d, 2^a3^b7^cp^d and 2^a3^b5^c7^d are obtained.  相似文献

科技期刊集团化发展路径探索 ——以煤炭科学研究总院出版传媒集团为例     

朱拴成 《编辑学报》2020,32(5):476-480

随着科技期刊发展外部环境的改变和自身发展需要,科技期刊规模化、集团化发展已形成行业共识。但是目前还未找到有效解决期刊布局分散、体制机制不活、市场化程度低、传统固化思想束缚等问题的方法和途径,科技期刊集团化发展仍处于观望探索者多、做实做优者少的尴尬境地。因此,亟需探索出一条适合我国国情的科技期刊集团化发展路径,让我国科技期刊真正走上集团化、数字化、产业化、品牌化、国际化发展的健康可持续发展道路,打造精品科技期刊刊群,争创世界一流。本文总结了煤炭科学研究总院出版传媒集团探索出的集团化管理模式和管理经验、亟需解决的问题及下一步发展规划,以期为同行期刊集团化发展提供参考和借鉴。  相似文献   

生态文明视域下民族地区的跨越式发展——以四川省甘孜州为例     

曾雪玫 《四川师范学院学报》2011,(4):93-97

民族地区的跨越式发展是建立在其独特的比较优势和后发优势基础之上的。但在道路选择时,鉴于民族地区重要的生态屏障和特殊的原生态文化保护区的地位、经济发展与环境保护之间的矛盾,决定了民族地区的跨越式发展必须突破传统工业化的“高速度”的跨越模式,走生态文明的道路。  相似文献   

排斥与全纳——全纳教育视野下的教育排斥研究   总被引：1，自引：0，他引：1  

吕寿伟 《外国教育研究》2011,(9):86-91

全纳教育的提出是因为教育排斥的存在,全纳教育与教育排斥之间存在着内在的、必然的关联。全纳教育视野下的教育排斥在对象上经历了针对残疾儿童的教育排斥、针对弱势群体的教育排斥和面向所有儿童所可能引发的教育排斥;在内容上也经历了机会排斥、质量排斥和参与排斥。对教育排斥认识上的深化使得全纳教育被赋予了更为丰富的内涵。然而,全纳教育并没有形成对教育排斥的系统化研究,这使全纳教育视野下的教育排斥不可能获得系统化、理论化的建构而依然停留于经验和直观的层面,从而使全纳教育无论在理念层面还是在实践层面都只获得了有限的成功。  相似文献

Action groups as a participative strategy for leading whole-school health promotion: Results on implementation from the INCLUSIVE trial in English secondary schools     

Emily Warren  Leonardo Bevilacqua  Charles Opondo  Elizabeth Allen  Anne Mathiot  Grace West  Farah Jamal  Russell Viner  Chris Bonell 《British Educational Research Journal》2019,45(5):979-1000

Education policy increasingly promotes action groups as a key strategy for student and/or staff participation in school improvement and whole-school health promotion. Such groups can coordinate multi-component interventions, increase participation and engagement, and enable local adaptations, but few process evaluations have assessed this. We evaluated fidelity, feasibility and acceptability of action groups as part of a trial of a whole-school intervention to reduce bullying and aggression and promote health in English secondary schools, which reported multiple health and educational impacts. Action groups involved students and staff, supported by external facilitators, and drew on data on student needs. They aimed to: coordinate implementation of restorative practices and a social and emotional competencies curriculum; review policies and rules; and enact local decisions to modify school environments. Our process evaluation used interviews, focus groups, observations and questionnaires to assess action groups’ fidelity, role in coordination, role in local adaptation, support from external facilitators and data on student needs, and acceptability in engaging members. Fidelity was high in the first two years but lower in the third year when external facilitators withdrew. Student needs data were perceived as useful, but views on external facilitators were mixed. Groups successfully reviewed policies and rules, planned activities and coordinated restorative practices, but were less successful in implementing the curriculum. Success was facilitated by the involvement of school leaders. Members reported high satisfaction and empowerment. Action groups are a promising strategy for leading whole-school health promotion. Implementation is supported by external facilitation, local data and involvement of senior managers.  相似文献   

Building a just world: the effects of service-learning on social justice beliefs of Chinese college students     

Yulan Li  Fengning Song  Jin Fu  Xiulin Chen 《教育心理学》2019,39(5):591-616

This study aimed to examine the effects of different service experiences on the social justice beliefs of 60 Chinese college students with mixed methods. The quantitative results indicated that the participants in two service groups (i.e. for at-risk adolescents and adolescents with cerebral palsy) demonstrated a more significant promotion of social justice beliefs than their peers in non-service group. A qualitative analysis provided evidence of the mechanism underlying service-learning, as well as different service experiences affecting on students’ social justice beliefs. Finally, the implications for implementing service-learning and realizing social justice goals in China were discussed.  相似文献
