教师专业发展:内地中外合办大学与香港职业技术教育与培训机构的实践比较

本研究旨在探讨两项教师专业发展计划的影响:一所是内地的中外合办大学,另一所是香港职业技术教育与培训机构。中外合办大学的专业发展课程既有自愿性的,也有强制性的,并由高等教育机构预先认证。香港职业技术教育与培训机构的专业发展课程包括不经外部机构认证的内部强制培训。本研究的独特之处在于通过与香港职业技术教育与培训机构制订的教师能力建设计划相比较,来探究亚洲环境中英国教师专业发展干预的有效性。通过焦点小组、半结构式访谈和调查问卷收集数据,形成教师对这两种教师专业发展干预措施的意见,这些见解有助于各机构在全球扩展中制定前瞻性教师专业发展战略。

Restoration of the Western Himalaya： implications for metamorphic protoliths, thrust and normal faulting, and channel flow models

The Greater Himalayan Sequence （GHS） is composed of a sequence of Barrovianfacies metamorphic rocks up to kyanite or sillimanite ＋ K-feldspar grade, migmatites, layered stromatic migmatites and leucogranite sheets. These rocks were metamorphosed during the late Eocene to early Miocene, and are bounded below by a large-scale SW-vergent ductile shear zone-thrust fault （Main Central Thrust; MCT）, and above by a NE-dipping low-angle normal sense shear zone and fault （Zanskar Shear Zone; ZSZ）,

Shrinking in the dark: Parallel endosymbiont genome erosions are associated with repeated host transitions to an underground life

Microbial symbioses have had profound impacts on the evolution of animals.Conversely,changes in host biology may impact the evolutionary trajectory of symbionts themselves.Blattabacterium cuenoti is present in almost all cockroach species and enables hosts to subsist on a nutrient-poor diet.To investigate if host biology has impacted Blattabacterium at the genomic level,we sequenced and analyzed 25 genomes from Australian soil-burrowing cockroaches(Blaberidae:Panesthiinae),which have undergone at least seven separate subterranean,subsocial transitions from above-ground,wood-feeding ancestors.We find at least three independent instances of genome erosion have occurred in Blattabacterium strains exclusive to Australian soil-burrowing cockroaches.These shrinkages have involved the repeated inactivation of genes involved in amino acid biosynthesis and nitrogen recycling,the core role of Blattabacterium in the host-symbiont relationship.The most drastic of these erosions have occurred in hosts thought to have transitioned underground the earliest relative to other lineages,further suggestive of a link between gene loss in Blattabacterium and the burrowing behavior of hosts.As Blattabacterium is unable to fulfill its core function in certain host lineages,these findings suggest soil-burrowing cockroaches must acquire these nutrients from novel sources.Our study represents one of the first cases,to our knowledge,of parallel host adaptations leading to concomitant parallelism in their mutualistic symbionts,further underscoring the intimate relationship between these two partners.

综述前苏联关于地表沉陷的煤炭地下气化经验（英文）

1.相比于传统的煤矿开采方法,煤炭地下气化的适用范围更广,但同时也可能引起地下水污染和地表沉陷。2.前苏联在煤炭地下气化方面拥有一段很长的研究和使用历史,由于当时的国际环境,前苏联的研究相对比较封闭,所以对其研究成果的综述目前仍然很有价值。3.综述了不同煤层参数(如煤层深度、倾斜度、高度、宽度、含灰量和地质剖面等)和气化燃烧相关参数(如岩土材料导热性、热损耗、热冲击和体积变化等)与地表沉陷的相关性研究。
