創新商業模式下之資訊服務需求分析-以團體旅遊為例 / Information service demand analysis of innovative business model - a case study of group travel

吳守謙, Wu, Sou-Chein Unknown Date (has links)
2015年臺灣超過1,300萬人次出國,並由3,000多家旅行社服務,臺灣旅遊業競爭相當激烈。資訊科技與網際網路興起,促使電子商務模式日臻成熟,線上旅遊產品通路(OTA)也順勢發展。並且,全球廉價航空公司興起,航空公司因競爭激烈,利潤降低而欲向下游整合,自行創立旅行社直接服務消費者,都使得傳統旅行社面臨被去中間化的威脅。 因此,本論文透過SCP模型分析臺灣傳統旅行社的發展階段和政策的影響,以及市場結構、企業行為與市場績效,用以解釋目前旅遊產業的環境及所面臨的困境。接續針對專家學者、消費者及通路商進行專家問卷訪談,得到團體旅遊創新商業模式,用以檢視個案旅行社積極引進資訊科技改善作業效率,結合資訊科技與旅遊產業經營知識的整合運用,串接整個旅行產業內外部的價值鏈,達到旅客需求傳遞一致及服務不中斷,讓自身得以產生中間價值,是否符合團體旅遊產業鏈再中間化之成效。最後針對個案公司給予相關建議。 / In 2015, over 13 million people in Taiwan traveled abroad and they were serviced by more than 3,000 travel agencies, showing how fierce competition is in the travel industry. At the same time, the rise of both the information technology and the Internet has led to the maturation of the E-Commerce model, followed by the development of online travel agencies. Moreover, the rise of low-cost airlines has prompted traditional airlines to start their own travel agencies and directly serve their customers, in order to compensate for the loss in profits due to increased competition. All factors mentioned above indicate the threats faced by traditional travel agencies nowadays. Therefore, this dissertation is aimed at understanding the current travel industry in Taiwan as well as challenges it faces by using the SCP model to analyze the following: phases involved in the development of traditional travel agencies, influence of governmental policies on the travel industry, market structure, corporate behavior and market performance. Furthermore, this dissertation will introduce an innovative business model for group traveling, obtained after interviewing experts, scholars, business customers and distributors. The model is then used to check whether effective reintermediation of the group traveling industry will occur by reviewing a specific case company, which has actively introduced IT to improve its operating efficiency, combined it with knowledge in management of the traveling field, and connected the value chain within and without the whole travel industry,. These actions have contributed to consistent transmission of travelers’ needs and uninterrupted service, which then increased the value of the case company itself as a middle man. Finally, this dissertation proposes several recommendations for the case company.

維克特爾•彼列文短篇小說之俄國後現代特性

林哲意 Unknown Date (has links)
俄國後現代主義雖接受大部分西方後現代主義的特質,然俄國後現代主義卻擁有異於西方後現代主義本質上的特點,包括俄國歷史發展由社會主義過渡到民主政體的獨特性,社會價值、意識形態實質上的危機,先前神話與意識形態的膨脹導致「真實」的消逝,以及蘇聯烏托邦的瓦解所帶來的「歷史終結」。所選四篇彼列文的短篇小說表現出特定的相似點:諷刺手法,「真實」的問題,文本互涉手法,對知識論的不信任,去意識形態化,哲學思維方法。本論文嘗試將當代受歡迎之彼列文的短篇小說中所蘊含的後現代特點系統化,並依據這些特點具體分析《透明世界》《維拉•芭芙洛夫娜的第九個夢》《隱士與六指》《妮卡》這四篇短篇小說。彼列文以去神話化、去意識形態化、去象徵化、去隱喻化、悖論、雙關語、矛盾修辭法等文藝手法具體表達「諷刺敘述模式」。本文列舉並評論在短篇小說中文本互涉之引喻、玄秘情節,聖經、神話、社會的象徵意義,同時也分析研究文本片段之修辭、語言對比差異。

台灣高中學生英文作文中表達過去時間標記之分析 / An Analysis of past reference marking in Taiwan senior high school students' english compositions

闕光賢, Chueh, Kuang Hisen Unknown Date (has links)
漢語沒有像英文嚴格的時態標記,因此,多數中國學生開始學英文時會有動詞過去式標記上的困難,在表達英語過去時間概念時,中國學生特別依賴時間狀語。為了了解中國學生表達過去時間概念時,時間狀語所扮演的角色,本文藉由觀察高中學生為期一年的作文,探討中國學生時間狀語的使用位置、時間狀語及動詞過去式標記之間的關係、中國學生過去式動詞標記上的困難。藉由以上三個方向的探索,可以更了解學生使用的時間狀語和過去式動詞的標記。 研究結果顯示,中國學生在英文作文中,時間狀語的使用頻率明顯偏高,且使用頻率有隨時間逐漸增高的趨勢,而時間狀語出現的位置,因英語程度不同有別,程度較高的同學,時間狀語出現在句首及句尾的比例相近,無明顯偏好;但是程度偏低的同學,則普遍偏好將時間狀語置於句首,類似漢語時間狀語出現的位置。 時間狀語同時也影響著學生標記過去式動詞的比率,倘若一個限定動詞在同個句子中有對應的時間狀語,則這個限定動詞較有可能標記為過去時態,這樣的現象又以英語程度較低的同學最為明顯。 在動詞過去式標記上,本文發現有過半的同學曾將was/were當成過去式動詞標記,置於限定動詞之前;此外,語料中也發現,有幾位同學會將用過去進行式及過去被動式誤用在過去簡單式之中,這樣的現象,有可能是因為學生認為有was/were即為過去式的標記所致。 透過本文的研究可看出時間狀語對於中國學生標記英語過去時間概念上的重要性,也可看出語言遷移(language transfer)在語言習得中的影響力,期許本文的發現能在英語習得及教學上有所助益。 / / Without tense marker in Mandarin Chinese, most Chinese EFL learners have difficulties in past tense marking in the beginning of learning English. Before marking past tense steadily, Chinese EFL learners tend to depend mainly on temporal adverbials in expressing past time. Temporal adverbials seem to play important roles during the process of acquiring tense marking. The present study tries to observe how Chinese learners use temporal adverbials to express past time and what kinds of difficulties learners have in past tense marking. Furthermore, we attempt to investigate the relation between tense marking and temporal adverbials. By analyzing learners’ composition, we found that Chinese EFL learners have high frequency in using temporal. Most learners are prone to put temporal adverbials in sentence-initial position except for learners with higher proficiency. Besides, learners are more likely to mark past tense co-occurring with temporal adverbials. Morphologically, Chinese EFL learners seem to regard was/were as a past-tense marker and put was/were in front of finite verbs ungrammatically. These findings manifest the importance of temporal adverbials for Chinese EFL learners in expressing past time and provide potential explanations for tense errors.

具有多重流量控管網路之離開過程 / Departure Processes of Multi-Traffic Networks with Input Control

余文政, Yu,Wen Cheng Unknown Date (has links)
參考Yue等論文,我們延續探討在通訊網路中對於非及時Available Bit Rate(ABR)資料與及時Variable Bit Rate(VBR)資料共同使用一條傳輸的等候模型。假設及時VBR資料傳輸較非及時ABR資料傳輸有優先權,我們建立與分析資料在離開過程之模型。本論文研究在非強制性優先權策略下之一般等候模型,藉由ABR資料的等候區域設立檢查點來控制流入量,在離開過程中推導VBR資料與ABR資料的離去時間的數學關係式,以及調查他們的數值模擬的表現。在此數學推導中需要藉MMBP關係,從ABR資料的等候區域觀點製造Markov矩陣算出穩定狀態下的機率分量、生成函數以及閒置時間的函數。結果發現檢查點影響兩者的離去時間並不顯著,但是VBR資料流入的速度卻會造成影響。 / Following the work by Yue et al., this thesis considers the departure of a multi-traffic network system for a popular communication network where a transmission link is shared by an Available Bit Rate (ABR) application for non-real time traffic and a Variable Bit Rate (VBR) application for real time traffic. It is assumed that the VBR traffic has a higher transmission priority than the ABR traffic. In this thesis, we establish a tractable analytical model of departure processes for such a system. The departure process is characterized by a general queueing model with a non-preemption policy for which the inter-departure times of VBR and ABR are derived, respectively. Since the VBR traffic is only affected when ABR is in service, the analysis is given to describe the departures of ABR, and VBR traffics. Numerical results are conducted to illustrate the system performance with input control of ABR traffic.

杜宇神話與唐詩中杜宇意象之研究

許秀美 Unknown Date (has links)
本論文以「杜宇神話」為主題,既探究神話的文本生命,明晰其情節變化、形成背景與內在意涵,又以「唐詩」為範疇,細究杜宇意象的文學生命。故本論文分成兩大部分:上篇「杜宇神話研究」,下篇「唐詩中杜宇意象之研究」。上篇先整理古代典籍中杜宇神話的相關記載,以明瞭情節的變化與取捨;接著進入口傳文學蒐羅從古籍杜宇神話發展而出的民間故事,探究從古籍本到民間文學的流傳過程中,杜宇神話的傳承性與變異性。上篇最後一章則深入杜宇神話,探析其形成背景與內在意涵,先從蜀地的時間、空間與人文背景尋訪其形成因素,再就「鳥崇拜」、「農神信仰」、「死而復生」三方面探詢其豐富的神話思維。下篇以唐詩中杜宇意象為研究主體,依主體思想的表現分成「托物詠懷——個人情志之寄託」、「思人(友、親)懷鄉——相思離愁之觸媒」、「借古諷今(借事諷喻)——時代控訴之載體」三章,為方便作品之分析,各章均分「盛唐」、「中唐」、「晚唐五代」三節詳加探討。最後比較出不同主題思想與不同時期杜宇意象使用機制的變化與書寫策略的改變,並明晰唐代詩家對杜宇意象的開發與貢獻及杜宇意象四川文化意義的深層內蘊。
