Information and Communication Technologies and Informal Scholarly Communication: A Review of the Social Oriented Research

This article reviews and analyzes findings from research on computer mediated informal scholarly communication. Ten empirical research papers, which show the effects and influences of information & communication technologies (ICTs), or the effects of social contexts on ICTs use in informal scholarly communication, were analyzed and compared. Types of ICTs covered in those studies include e-mails, collaboratories, and electronic forums. The review shows that most of the empirical studies examined the ICTs use effects or consequences. Only a few studies examined the social shaping of ICTs and ICT uses in informal scholarly communication. Based on comparisons of the empirical findings this article summarizes the ICT use effects/consequences as identified in the studies into seven categories and discusses their implications

2kenize: Tying Subword Sequences for Chinese Script Conversion

Simplified Chinese to Traditional Chinese character conversion is a common preprocessing step in Chinese NLP. Despite this, current approaches have poor performance because they do not take into account that a simplified Chinese character can correspond to multiple traditional characters. Here, we propose a model that can disambiguate between mappings and convert between the two scripts. The model is based on subword segmentation, two language models, as well as a method for mapping between subword sequences. We further construct benchmark datasets for topic classification and script conversion. Our proposed method outperforms previous Chinese Character conversion approaches by 6 points in accuracy. These results are further confirmed in a downstream application, where 2kenize is used to convert pretraining dataset for topic classification. An error analysis reveals that our method's particular strengths are in dealing with code-mixing and named entities.Comment: Accepted to ACL 202

Cyber purchasing behavior of adolescent: Family communication relationships and parental influence

[[abstract]]With the advent of internet-consumer generation and changes in family structures, the purchasing power of teenagers has greatly increased. Since family communication patterns are still the primary source from which adolescents learn their purchasing behavior, parental influence on adolescent purchasing decisions cannot be ignored. Parents play a critical role in family communication and, thus, establish the consumer socialization model for cyber purchasing behavior of adolescents in this study. A sample of young people aged 16–30 was divided across three age spans. Family socioeconomic status was explored to see if it relates to different family communication patterns, and whether family communication patterns in turn influence cyber purchasing behavior of adolescent. The results show that compulsive purchasing behavior is affected by stages of the adolescent life cycle and by the mother’s education level. Adolescents whose family communication patterns are concept-oriented tend to incur more planned buying. If the family communication patterns are social-oriented, the individual tends towards unplanned shopping behavior. The results show that, in addition to the adolescent life cycle and family communication patterns, family socioeconomic status and parental marital status also affect adolescent cyber purchasing behavior.[[notice]]補正完

兩岸工業部門國際分工程度之比較分析

本文擬從長期的資料著手，首先以產業內貿易指數觀察兩岸貿易型態與國際分工的變化情形，接著針對產業內貿易指數的缺點提出疑問，並配合貿易專業化係數或質易特殊化係數(Trade Specialization Coefficient, TSC) 重新定義國際分工型態。由TSC值進一步觀察兩岸歷年對全球貿易中，工業部門的國際分工型態，並以「雁行」理論，探討兩岸產業的發展關{系。 本文共分陸節，除前言外，第貳節是圓際貿易與國際分工型態的文獻回顧，第參節敘述貿易資料來源與國際分工指標，第肆富有分析臺灣地區國際貿易與分工型態時間趨勢，第伍節說明臺灣地區產業政策與國際分工型態反轉的形成，最後則是結論

The assessment and planning of bicycle paths surrounding the bridge in Taipei, Taiwan

近年來台灣一股自行車風行之熱潮，各縣市政府逐漸重視自行車行車空間，紛紛廣設自行車道，然而目前自行車道連續部分，如橋樑之處理，因受限於橋面上可用空間而確實較少進行研究與探討。就台北市內現有自行車道中，僅規劃幾處自橋面通過，但多數區內橋樑扮演民眾通勤與通學之運輸功能，故有規劃開放自行車旅次使用之必要性。另一方面，台北市區中多數橋樑跨越河川，具有坡度，往往讓自行車騎乘者感到不便，也不適宜規劃與其他車種共道而產生衝突之疑慮，且橋樑與河岸周邊多具有通勤型與休憩型自行車道整合問題，在考量自行車事故安全與使用連續性的情況，本研究將探討上述兩議題，規劃與設計橋面上自行車道設置以及相關自行車牽引道，以滿足當地之自行車道系統使用與連續之需求與功能。本研究以台北市承德橋為例，此橋樑具有坡度且坡道長，自行車騎乘不易，騎乘者常在機慢車道或右轉車道上牽引車行走，故目前常有自行車與其他機車於機慢車道上發生事故。再者基隆河兩岸河濱自行車路線未銜接，且下橋處三所學校學生有自行車通行之需求，故承德橋自行車道規劃勢必需將運輸型及休憩型自行車道路線作一整合之工作，在此應有一套系統之流程，合理評估與規劃橋樑周邊自行車道與牽引道之實際佈設形式，以達到自行車系統完整性之設計。 因此，本研究將透過系統化流程分析方式，探討自行車騎士騎乘於橋面上之能力，分析之項目涵蓋負二項肇事分析、交通工程、道路幾何特性、駕駛行為、行駛特性等，並且設計一套自行車道連續之系統評估與規劃流程，冀望找出市區橋樑周邊自行車道與牽引道最佳之佈設方式，以改善目前自行車騎乘安全及便利性，進而提供交通及警察相關單位作為改善橋樑周邊自行車易肇事地點安全或評估橋樑交通管理措施可行性之參

巨額土砂匯入對和社溪河相演變之影響

Macro-sediment impulses induced by particular typhoons and rainstorms are the main reason for serious sediment disasters in the Heshe River. For example, the sediment input during Typhoon Morakot in 2009 which accounted for 95.8% of the annual sediment discharge is the most serious of these disasters. Since Typhoon Morakot, the sediment input has decreased, as there have been less serious typhoons and rainstorms, thus, transforming the river morphology from a braided river into meandering river. In addition, river bends and topographical notches restrain sediment from moving downstream and store it in these locations. These factors have indirectly increased the erosion density of the river banks by 2.5 to 10.5 times.特定之颱風及豪雨事件為和社溪集水區內巨額土砂進入河道造成相關土砂災害之主 要因素；尤以2009 年莫拉克颱風其間之輸砂量，佔該年總輸砂量之95.8％最為嚴重。然而，莫拉克颱風過後並無發生規模較大之颱風及豪雨事件，因此進入和社溪之土砂漸減，使得因土砂堆積造成之辮狀河川逐漸走向蜿蜒。此外，河川轉折點跟隘口處都會抑止土砂往下游運移並使土砂集中於此處，間接造成河岸淘刷密度增加2.5 至10.5 倍

15_四大工業

「穿膠花」、「剪線頭」是不少老一輩香港人的集體回憶。1950年代，韓戰禁運、內地移民等因素促使香港工業起飛，使這個轉口港搖身一變成為世界工廠。當中「紡織及製衣業」、「塑膠及玩具業」、「鐘錶業」和「電子業」發展尤為突出，獲得了「四大工業」的美譽。這些港製產品價廉物美，遠銷歐美市場，取得了驕人成績，使「香港製造」品牌蜚聲國際。然而隨著內地在1978年推出改革開放政策，香港工廠相繼北移，四大工業亦逐步轉型。本展覽將介紹四大工業的發展，重溫香港製造業的黃金歲月。https://commons.ln.edu.hk/jchkhlp_exhibitions/1017/thumbnail.jp

[[alternative]]Asymmetric Dynamic Relationship between Futures and Underlying Stock Price Using U-STECM

計畫編號：NSC94-2416-H032-019研究期間：200508~200607研究經費：547,000[[abstract]]本研究將分別取以美國S&P500指數及台股指數之期貨契約為研究對象，著重研究方法創新之應用，在考慮交易成本等多項因子，且考量到受正與負不同價格偏誤行徑所產生的非對稱情況之不完美市場下，運用非對稱平滑移轉誤差修正模型(U-STECM)為主之架構，分別探討各個市場中期貨價格與標的股價間之長短期動態關係。U-STECM模型改良ESTECM呈對稱型態的缺點，除了能捕捉正與負非對稱性價格偏誤之特性外，另允許了較寬幅度的無套利區間，使得移轉方程式呈現為U型。以U-STECM實證比較分析各個市場中期貨價格與標的股價間之互動關係，更可藉以瞭解兩個金融資產間之基差非線性走勢行為，並分析套利機會存在空間之大小。[[sponsorship]]行政院國家科學委員
