光影在现代景观设计中的作用表现与构建手法探析

光产生影,影反映光,光影共同作用能彰显景观中各种要素的更多层次与内涵。针对现代景观设计中的光影作用,深入分析自然光、人造光及阴影,研究它们共同作用于色彩、造型、材料、空间等有形的物质要素和心理、意境等无形的精神要素,进而分析实现光影效果的各种构建手法,从而达到营造富有光影表现力和意境的景观空间及场所的运用目标。     

论手部动作范畴向心理范畴的演变

从手部动作范畴到心理范畴的演变是人类认知思维的典型体现,涉及这一演变的词非常多。演变方式主要有三种：隐喻、转喻、语义沾染,其中以隐喻最为常见。人们习惯于用身边具体的事物来比照心理情绪等抽象之物,进而用具体的动作动词去操控它们,其结果就是手部动词衍生出心理义。有时人们以显著的外部动作来转指心理状态、性格等,这样部分手部动词就获得了心理义。     

Student injuries in the dissecting room

Cadaver dissection is the first opportunity for many students to practice handling human tissue and is their first exposure to the occupational hazards involved with this task. Few studies examine dissection room injuries to ascertain the dangers associated with dissecting. We performed a retrospective cohort analysis of dissection room injuries from four student cohorts over an eleven‐year period (2001–2011), including second‐year medical students, third‐year medical students, second‐year dental students, and third‐year science students. Injury data included activity causing injury, object responsible, and injury site. A total of 163 injuries during 70,039 hours of dissection were recorded, with 66 in third‐year medical students, 42 in second‐year medical students, 36 in third‐year science students, and 16 in second‐year dental students. The overall rate was 2.87 injuries per 1,000 dissection hours, with second‐year medical students most frequently injured (5.5 injuries per 1,000 hours); third‐year medical students were least frequently injured (1.3 injuries per 1,000 hours). A significant difference in injury rates between student groups indicated a higher than expected injury rate to second‐year medical students and lower than expected rates to third‐year medical students. Injury rates increased for most groups between 2001–2006 and 2007–2011 periods. Most injuries (79%) were from scalpel cuts to the finger or thumb. This study provides injury rates for dissection room injuries to students, indicating differences in injury frequency between cohorts and an increase in injury rate over time. As scalpel cuts were the most likely injury mechanism, targeting scalpel handling with preventative strategies may reduce future injury risk.

Evaluating the Children's Literature Collection

This article reports on an evaluation study of the Children's Literature Collection conducted at Gustavus Adolphus College Library in 1992. Among the goals were to assess quality and extent of the collection and to find out why students were dissatisfied with the collection. The methodology included the inductive method of checking a collection against a major review instrument and annual lists of "best" titles, as well as a user survey in order to compare findings about quality and size of the collection with students' perception of the two measures. Surprisingly it was found that students major dissatisfaction stemmed not so much from lack of quality and quantity of the collection but rather from problems with access via the online catalog and shelf arrangement.

经济转型过程中政府作用的重新界定

目前关于政府作用的模型有三个,即看不见的手模型、扶持之手模型以及掠夺之手模型。从不同的角度出发,看待政府的作用各不相同。在转型的约束条件下,政府除了完成市场化国家政府的一般职能外,其职能还需要重新界定。首先强化人力资本的投资;其次,转型国家的政府必须协调利益集团之间的关系;再次,提高财政能力;最后,转型国家的政府要注意克服信息不对称的问题。政府可以充当看不见的手听任市场的自行其是,也可以采取扶持之手推进改革的顺利进行,还可能伸出掠夺之手与民争利,因此,限制政府的掠夺之手使其成为有限而又有效的政府,是至关重要的。政府转型成为中国经济转型的重要制约因素。
