北漂之梦、爱情之痛与时代之殇——《火烈鸟》中的现实主义维度

电影《火烈鸟》将镜头瞄准当代“北漂”青年的现实生活,阐发他们的人生理想、爱情经验与社会困惑,从而成为近年来国产现实主义文艺片佳作。该片首先呈现了当代青年对“北漂”现象的文化想象与现实困境;其次描绘了物质主义之下对爱情的温暖寄予与冰冷遭遇;最后剖析了现代道德所面临的价值坚守与标准失衡。本片的意义不仅在于其用现实主义手法将青年们的真实生活予以呈现,更是为了引起我们思考其背后的时代症候与文化嬗变。

火烈鸟大迁徙

非洲的纳古鲁湖被称为“火烈鸟的天堂”，每天的湖水之上总是浮动着一条条红色的彩练，如落英逐逝水，似朝霞映碧池，给雄险的大裂谷平添了几分优柔妩媚的韵致。织成这美丽彩练的就是火烈鸟。一只只斑斓绚丽的火烈鸟积聚在一起，一池湖水就顿时被映照得通体红透，便成为一片烈焰蒸腾的火海，一道“世界上火光永不熄灭的奇观”。

The reliability of morphometric discriminant functions in determining the sex of Chilean flamingos Phoenicopterus chilensis

Monomorphic birds cannot be sexed visually and discriminant functions on the basis of external morphological variations are frequently used. Our objective was to evaluate the reliability of sex classification functions created from structural measurements of Chilean flamingos Phoenicopterus chilensis museum skins for the gender assignment of live birds. Five measurements were used to develop four discriminant functions： culmen, bill height and width, tarsus length and middle toe claw. The functions were tested on a sample of live flamingos from a zoo. The best classification for museum flamingos was given by a function using tarsus length, bill width and middle toe claw （97%）. However, this function did not give the best classification for the zoo-based flamingos （81%） which had the best sex assignment by a function including measurements of tarsus, culmen and bill height and width （85%）. This shows that a function giving good results in the sample from which it originated may not be as good when applied to another group of animals. Our study emphasizes the need for assessing the accuracy of a function by testing it with other methods to ensure its suitability when being applied .
