good-looking professors get higher teaching evaluation scores?

"It was God who made me so beautiful. If I weren't, then I'd be a teacher."
-- Supermodel Linda Evangelista

前一陣子導生聚時,有人說老師你好像很喜歡有格子狀的衣服喔(還是你只有那幾件;-))

這件事我還真從來沒想過。打從學生時代起,也許是省錢,加上覺得去反叛時尚價值是哲學家的天職 (不過後來才發現許多當代法國男性思想家穿著可潮得很呢),根本沒注意自己在穿什麼,可說是完全沒有穿著美學上的修養。大半時候甚至連應隨天氣變化加減衣物這件事都不關心,更不用提如何搭配與拿捏衣著的顏色、材質來美化體態,或是展現個人風格。

剛剛出統計習題時看到一個教育經濟學的研究 BEAUTY IN THE CLASSROOM: INSTRUCTOR'S PULCHRITUDE AND PUTATIVE PEDAGOGICAL PRODUCTIVITY,
ABSTRACT
Adjusted for many other determinants, beauty affects earnings; but does it lead directly to the differences in productivity that we believe generate earnings differences? We take a large sample of student instructional ratings for a group of university teachers and acquire six independent measures of their beauty, and a number of other descriptors of them and their classes. Instructors who are viewed as better looking receive higher instructional ratings, with the impact of a move from the 10th to the 90th percentile of beauty being substantial. This impact exists within university departments and even within particular courses, and is larger for male than for female instructors. Disentangling whether this outcome represents productivity or discrimination is, as with the issue generally, probably impossible.



阿你不是說過現在的老師跟演員沒什麼不同嗎?果然。呵呵,下學期是不是要染個紫色的頭髮來嚇嚇大家 ;-)

學者風範

前些日子參加語言學學會會員大會,有緣聽到湯廷池教授的演說,感到相當的親切。倒不是因為曾跟湯老師一樣有修習法律的經驗,而是在他徐徐道來的生命回顧中,展現出來的,那種對知識追求的單純興趣、對知識傳播的熱情投入。

最後他說,".... 現在,就是把自己當成回收資源讓大家再利用,最後呢,回歸大地的懷抱。" 何等鏗、鏘、有、力!

只要量夠大:書籍影片版

看到 shuyen 的留言,我再提供一個在此新的計算典範下的另一範例給有心者作參考。

這篇要談的是 Philip Parker 教授。各位可先看紐約時報的這篇報導。這位號稱「地球史上最多產的作家」,在網路書店亞馬遜,可發現他已撰寫超過二十萬本的書籍 - - 請注意,這些都是用電腦程式寫出來的。什麼?有沒有聽錯?!雖然他的用意是在於提供出版界 POD (print on demand) 的新思維,但是他發展出來的內容生產自動化專利 (automated content creation) ,一份 250 頁的 industry forecast report,只不過花了 13 分鍾。

別鬧了,誰會去看他的書啊,你說。那你大概不知道,我們堂堂國立台灣師範大學總圖書館,就買了他 14 本書。(不信邪者請用 Parker, Philip M 作者查詢其他各大圖書館)。以下是他自己的介紹:





與此平行者,其實還有另一種更猛的計算典範,我在博士論文中稱它為漢字知識本體。改天有空再介紹給大家。這個領域應該是由中文電腦之父朱邦復先生最先發展,並應用到語言與影像資訊領域。已傳聞已久即將面市的是"自動圖文系統"(text-to-scene)。也就是說,給電腦一篇古典詩詞或小說,他幫你自動生成一部動畫影片。以下是首部公開的全自動圖文影片《記承天寺夜遊》,全片純由電腦製作,完全未有人力協助。




這世界,會變得怎麼樣子。(廣告:大家趕快來念計算語言學 ;-))

只要量夠大:詩歌版

以下摘錄電腦詩人 shukai 創作新詩一首:(只花三秒)
《窗檯下的思念》
http://www.dopoem.com


誰在用老吉他彈奏一曲《夢中的家》
歲月在牆上白鷺鷥看見小時候
猶記得那年我們都還很年幼
而如今琴聲幽幽我的等候你沒聽過

誰在用老吉他彈奏一曲《夢中的家》
秋雨將故事染色結局我看透
窗檯下的古道我牽著你走過
心無片瓦的年頭就連分手都很沉默

只要量夠大:部落文版

一直想找機會紀錄最近一些和語言計量與文本研究有關的心得。(其實應該放在research blog 上的,不過因為應用上具有娛樂性,也許可藉此機會替計算語言學作點宣傳;-))

Extremely Fatigue


It was on like Thursday or Wednesday I don't really remember. I had the thought, in the middle of my spiky moments on Tuesday and Wednesday, that I've probably been on a wrong track in my general efforts, perceptible through this journal, to keep undue hopefulness out of my daily round. I could probably make an educated guess about their ages. The first time, I knew the answer to their little trivia question and called at least 30 times. I immediately called the distributor and canceled it. He called 3 times, each time telling me that he really couldn't get the cab and he's gotten be real late. THE DAY the titles started showing up again, I called again. She stamped and wrote and stamped again in my passport, and then stamped some pieces of paper. I started thinking to myself that it was really more of a courtesy invite and Audoctor wouldn't go and Id be safe to enjoy my friends in a fun atmosphere. I just really don't like people that pretend their time is more valuable than yours. Is this really what I'm supposed to do?

不好猜出,這是一篇完全由程式自動"寫"出的部落格文章吧。給個主題,程式利用網路上大量的資料萃取與拼湊語言片斷,結果還造成頗似意識流的技巧。這是鉅量資料的可怕的地方!它讓AI研究傳統上一些 toy programs 起死回生。不具語言理解能力、單純的 pattern matching,輔以每日以驚人速度成長的語料,已經開始讓人誤以為 machine intelligence 已悄然誕生。人開始需要站在機器的角度去想,理解該怎麼定義?溝通又是什麼意義?

我看了看,這個程式寫得不難。改成中文版,多實驗幾次,加入一些 discourse parameters,要瞞過人的眼睛指日可待。你問我,做這個要幹嘛?嗯,第一好玩嘛,第二跑過一次,保證妳對於人與機器的語言理解與溝通有進一步的體悟。第三呢?至少我覺得可以是一篇 qualified 的計算語言學論文:)

Fingerstyle and Lifestyle

根本沒注意 Tommy Emmanuel 竟然在十月底時已來過台灣,我怎麼把自己的生活忙成這樣 :-(
