Preservice Teachers’ Collaborative Information Behavior while Developing Curriculum in Cooperative Learning Contexts
No full text本研究旨在探究師資生於發展教案之協作資訊行為及其合作經驗,針對一所研究型大 學三門以合作發展教案為目標之課程學生進行問卷調查,再從70份有效問卷之參與者中招 募14位師資生進行深度訪談。研究結果顯示,整體而言,師資生進行共同瀏覽、搜尋與組 織資訊等明確的協作資訊行為大多僅發生於合作任務分工之前。合作歷程中,協作資訊行 為發生頻率高者多來自分工與合作並重之組別,且以扮演協調者角色的師資生及投入任務 相關社交時間較多者尤然。具備上述特質的師資生,往往也運用較多種類之線上工具,其 感知合作成果亦較理想。本研究據此針對促成合作學習與協作資訊行為教學實務、師資培 育實務,及未來研究三方面提出具體建議。The purpose of this study is to examine the collaborative information behavior (CIB) and experiences of preservice teachers while developing curriculum in small groups. A survey was conducted with 70 students from three courses in a teacher preparation program in Taiwan, and followed up with 14 voluntary interviews among survey participants. The three courses that participants were taking share the same learning goal—promoting preservice teachers’ ability to develop curriculum through teamwork. Results show that specific CIBs, such as co-browse and co- search, only occurred prior to labor-distribution stage. In the process of curriculum development, preservice teachers who exhibited CIB more frequently typically came from teamwork/labor- distribution balanced groups, and tended to use a wider variety of online tools; compared to their low- frequency CIB counterparts, high-frequency CIB students also held more positive attitudes towards their perceived project outcome. Suggestions for facilitating cooperative learning, for future teacher education, as well as for future research, are provided based on the findings of the present study
補光與新舊椰纖屑對小胡瓜植株生長及果實產量與品質之影響
No full text本研究探討補光與新舊椰纖屑對小胡瓜植株生長與果實產量與品質之影響。小胡瓜‘秀秀’冬作栽培於臺灣大學太陽光與人工光併用型植物工場，利用新調製椰纖屑及第五次使用之調製椰纖屑為栽培介質，在光強度低於30 µmol·m-2·s-1時，以T5燈(Wellypower, FH 28W/865)於側面補光至光強度250 µmol·m-2·s-1及維持光週期14 h/10 h，並以不補光為對照組。同樣以新椰纖屑栽培，相較於不補光者，補光增加‘秀秀’相對葉綠素含量，並提高單株總果重、單株總果數、總可溶性固形物與抗壞血酸含量。無論補光與否，‘秀秀’以新椰纖屑比以第五次使用之椰纖屑栽培者有較多葉片數與節間數、較高株高與相對葉綠素含量，並可提早10天採收。綜合比較太陽光與人工光併用型植物工場之所有處理，‘秀秀’以補光-新椰纖屑處理具有最高之單株總果重(935.7 g)、單株總果數(7.6條)與抗壞血酸含量(74.4 µg·g-1)
Ways of Reading Women's History: A Review Essay on A History of Modern Taiwanese Women: The Birth of "Shin Joset" in Japanese Colonial Period
No full text作為日本學界第一本殖民地台灣女性史研究，洪郁如《近代台灣女性史》，從台灣末代纏足世代、解纏足世代到第一代新式女子教育世代出現，探討日治台灣「新女性」的誕生。這一部「新女性」的歷史，涵蓋了日本殖民統治下近代台灣社會變遷過程中新出現的性別角色：漢人傳統菁英家族待字閨中的小腳女兒、接受殖民地中等教育體制「賢妻良母」訓育的「女學生」、當「自由戀愛」成為社會問題的問題少女、滿足新世代菁英對外社交需要的得體妻子、「一夫一妻制」文明家庭的理想主婦，以及為帝國操持家政知識與育兒義務的母親
Historical Representation and Identity Politics in Seediq Bale: Against a Simple Dichotomy between Civilization and Barbarism
No full text本文將探討電影《賽德克‧ 巴萊》裡的歷史再現與認同政治。我認
為電影對霧社事件的歷史再現和電影裡的認同政治相互纏繞，試圖拆解
事件之內及其外文明與野蠻的對立。電影的歷史再現涉及了它所採取的
手法和對事件的詮釋，而後者又蘊含了認同政治，包含賽德克族的自我
認同或分裂認同、及其與電影隱含的台灣意識之關係。第一部分我先概
述過去對霧社事件的呈現，《賽德克‧ 巴萊》貼近賽德克族觀點如何可
能，第二部分討論片中的歷史再現，聚焦於太陽旗與彩虹橋兩組文化符
碼的對位(contrapuntal)呈現。第三部分探討電影裡如何透過描寫認同政
治與生死掙扎的關係，拆解野蠻與文明的對壘。結論則探討電影的環保
意識和當代意義。This article examines historical representation and identity politics in Wei
Te-sheng’s film Seediq Bale. I argue that the movie’s historical representation
of the Musha Incident is interwoven with its identity politics to deconstruct
the dichotomy between civilization and barbarism both in and beyond the
Incident. Whereas the historical representation has to do with its use of film
genres and interpretation of the Incident, the latter entails identity politics,
particularly regarding its portrayal of the Seediq tribesmen’s self-identity or
split identity as well as their relationship with the film’s implicit Taiwanese
consciousness. The first section traces the historical, literary, and filmic
representations of the Musha Incident in the past, which make it possible
for the film to adopt a view closer to those of the Seediq tribespeople. The
second section discusses the film’s historical representation by focusing on
the contrapuntal relationship between the two sets of cultural signifiers
surrounding the Sun flag and the Rainbow Bridge. The third section deals
with how the film debunks the dichotomy between civilization and barbarism
by its depiction of the relationship between identity politics and the Seediq
tribespeople’s struggle between life and death. The conclusion addresses the
film’s portrayal of Seediq community’s environmental consciousness and the
contemporary significance of the Incident the film brings into focus
Directors' and Officers' Liability Insurance, Debt Contracting, and Earnings Conservatism
No full text本文探討董監事責任保險是否影響我國企業會計盈餘保守性，並進一步研究債務契約的
影響是否得以解釋董監事責任保險對於企業會計盈餘保守程度的差異。本研究假設，當
公司購買董監事責任保險時，代理衝突的增加會產生更多的會計盈餘保守性。實證研究
結果顯示，購買董監事責任保險的企業中，承受較高外部融資壓力的公司報導更顯著的
會計盈餘保守特性。本研究結果支持債務契約需求導致盈餘保守性假說，亦即會計盈餘
保守性的實務需求主要來自於債權人對於降低代理衝突與促進契約效率有關。This study evaluates whether earnings conservatism increases when firms with high debt
contracting demands purchase directors’ and officers’ insurance (D&O). We expect that the
purchase of D&O insurance is positively associated with earnings conservatism only when
firms have higher debt-based contracting demands. We find that firms having D&O
insurance and higher external demand for debts report more earnings conservatism. These
results are consistent with prior studies (Ahmed, Billings, Morton, & Stanford-Harris, 2002;
Watts, 2003) that debtholders demand greater earnings conservatism as a means of
addressing agency problems. This study also provides evidence that debtholders appear to be
the primary driver of the demand for earnings conservatism
The Optimal Pricing, Promotion and Product Strategies of a Manufacturer in the Presence of Coupon Resale
No full text本研究分析價券轉售市場對獨佔製造商最適訂價、促銷與產品策略之影響。分析結果顯示折價券轉售市場的影響效果決定於高低端消費者是否有不同的機會接觸折價券轉售市場。當兩種消費者有相同的機會進入折價券轉售市場時，折價券轉售的活動就會對廠商造成傷害，且當折價券轉售活動對社會效率有越大的助益時，廠商所受到的傷害越大，此時折價券轉售市場的出現將會鼓勵廠商發展高端產品。反之，當高低端消費者有不同的機會接觸折價券轉售市場，且低端消費者較高端消費者在接觸折價券轉售市場上更具成本優勢時，折價券轉售活動可能有助於廠商區辨消費者，因而鼓勵廠商提供低端產品。This paper analyzes the optimal coupon and product strategies in the presence of coupon resale markets for a monopolist facing high-valuation and low-valuation consumers. The results show that the effects of coupon resale on the firm's product and coupon strategies depend crucially on whether the highs and the lows have differential access to the coupon resale market. When they have equal access, coupon resale hurts the manufacturer by reducing the optimal coupon face value, and the higher the social value of coupon resale, the more the manufacturer gets hurt. In this case, coupon resale encourages the manufacturer to develop a high-end item. When it is more difficult for the highs than for the lows to access the coupon resale market, coupon resale may facilitate screening for the manufacturer by reducing the effective redemption cost of lows, and may encourage the latter to offer a low-end item
