為了解決#If defined 的問題,作者 這樣論述:
Snuff (1976) occupies a unique place in cinematic history, as the first commercially successful film to capitalise upon the myth of the ’snuff’ movie. By blending cinema verité styling with a media moral panic, savvy producer Allan Shackleton’s blending of a long-forgotten exploitation film with
a newly filmed bloody, if unconvincing conclusion, only served to consolidate the belief that somewhere, at some time, someone was killed on camera in an attack that was as much about the sexual gratification of the film’s intended audience, as it was about the commercial rewards for those producing
the film. In the years since its release, the film has been routinely cited as ’evidence’ of the snuff movie’s existence, contributing to a cultural history that exists outside of the film. This book explores the production, distribution and exhibition of the film Snuff, alongside that cultural his
tory, considering how a scarcely seen exploitation film contributed to a popular understanding ofthe snuff movie. It assesses the cultural, cinematic and political legacy of the film and asks whether the established definition of what might constitute a snuff movie, that was defined 45 years ago, is
sufficient in an attention economy that is based upon participatory culture.

採用CUDA圖型處理器平行化改良5G軟體基地台之隨機存取通道流程
為了解決#If defined 的問題,作者王靖 這樣論述:
隨著5G逐漸於全球開始商轉,越來越多企業發現其中商機並相繼開發相關應用與服務,例如:無人機、物聯網、邊緣運算等,然而這些應用都需要基地台為其傳遞訊號才能正確運作,因此基地台本身的穩定與效能將是這一切的基礎。本論文即提出一改善方法以提升原基地台本身之運算效率使其能夠更穩定的提供服務。無線行動網路近年快速發展,於是有軟體化基地台(Software-defined Radio, SDR)的概念被提出並運行提供服務,此概念即透過編寫軟體程式提供傳統基地台之服務,以應付行動網路技術規格之快速發展與變遷。本論文在此基礎之上針對基地台中提供使用者註冊接入網路與使用者裝置同步服務的隨機存取通道(Random
Access Channel, RACH)流程,討論其傳統實作方法並提出一改善效率之方法與流程架構。本論文將研究使用圖型處理器(Graphics Processing Unit, GPU)加速平行RACH 流程上的運算,並修改運算流程與方法使之更適合運行於GPU。透過本論文提出的架構設計,基地台的模擬測試運算執行時間可調降至大約原本的10%~50%。本論文的架構亦提供彈性化設計,因此可一次處理多基地台接收之訊號,且由於本研究將所有運算拆開至不同運算單元上平行運算,所以即使需要處理的訊號增加,總處理時間也不會有太大的差異。藉此研究,軟體基地台運行時將能有更多閒餘的效能維持整體性之效能與穩定或是
提供更多服務應用。
前進中文:中級課程1(簡體版)(可下載雲端MP3) Progressive Chinese: Intermediate Course 1
![](/images/books/5496c669a228ae7812d17c366eff066e.webp)
為了解決#If defined 的問題,作者 這樣論述:
˙The learning goals that center on the thematic units are set in accordance with the language proficiency levels, established by the ACTFL ˙To Comply with the pedagogical principle of backward design to establish the teaching/learning goals for the intermediate learner of Chinese ˙
Integrates into its thematic contents the ACTFL-defined, three mores of language uses as well the 5C concepts ˙Assist the learner to achieve holistic progress and to cultivate specific linguistic abilities of Chinese ˙The selecting of keywords/phrases in thetextbooks is greatly in line with vo
cabulary levels defined by the HSK and by the TOCFL. The regional difference in language uses between the two sides of theTaiwan Strait are also meticulously annotated in the textbooks In recent years, the background of learners has become diversified, and the number of self-study students of ele
mentary Chinese is also increasing. On the pedagogical front, however, learning materials, found to be biased towards school life and youth culture, fail to meet the needs and interests of adult learners. In response to the current dilemma, “Progressive Chinese: Intermediate Course” is thus designed
for people from all works of life. “Progressive Chinese: Intermediate Course” is based on the results of action research done by experienced Chinese instructors affiliated in colleges and universities in the United States. This series of textbooks is a set of two volumes, and each volume is comp
osed of four thematic units. The learning goals that center on the thematic units are set in accordance with the language proficiency levels, established by the American Council on the Teaching of Foreign Languages (ACTFL). Specifically, “Progressive Chinese: Intermediate Course” attempts to help th
e Novice-High learner attain the proficiency level of Intermediate Mid (with the first volume), and then to the level of Intermediate High (with the second volume). “Progressive Chinese: Intermediate Course” complies with the pedagogical principle of backward design to establish the teaching/lear
ning goals for the intermediate learner of Chinese. Through various forms of formative and summative assessment, every lesson and every thematic unit constantly provides the learner with chances to re-consolidate their developing Chinese proficiency. As standardized ways of ensuring successful learn
ing, “Progressive Chinese: Intermediate Course” integrates into its thematic contents the ACTFL-defined, three mores of language uses as well the 5C concepts of Communication, Culture, Connection, Comparison, and Community. In addition to the overall progress in Chinese, “Progressive Chinese: Int
ermediate Course” attempts to cultivate the following specific linguistic abilities of Chinese: 1. To ask questions, to answer questions, to deal with simple social transactions, (forthe high potential learner) to narrate, to compare, and to describe. 2. To process and to produce Chinese text
s in paragraphs. 3. To develop strategies to comprehend audio and textual input: to put up with unfamiliar language units, to skim through materials, to infer information from co-texts. 4. To develop and apply language learning strategies to gradually become independent Chinese learners to ach
ieve the purpose of lifelong learning. ˙參照ACTFL所定語言能力標準設定學習目標 ˙依照反向設計的原則為中級學習者制定相應的教學目標 ˙結合ACTFL的三種交際溝通模式及5C理念設計教材 ˙幫助學習者獲得全面性的進步與具體的語言能力 ˙選詞參照了漢語水準考試(HSK)、華語文能力測驗(TOCFL),並兼顧兩岸差異 近年來華語學習者背景趨向多元,中文的自學者人數也日益增長。編者在教學中發現,偏向學校生活和青年文化的主題,常常無法滿足成年學習者的需求和興趣。因此傾力將《前進中文》編寫成一套能同時符合社會職場人士與大學生各自需求,
亦能符合其語言能力和認知程度的教材。 本教材由四位於美國教學中文的一線教師共同編著,為其教學後反思所做的行動研究成果,在出版前曾實際運用於教學中,藉此發現問題、獲得學生回饋,並進行調整,方完成最後編寫。本教材共兩冊,每冊四個單元,以主題進行規劃,並依照美國外語教學委員會(ACTFL)所制定的語言能力標準設定學習目標。第一冊目標由初級高提升至中級中;第二冊目標由中級中提升至中級高。 《前進中文》按照反向設計的原則,根據ACTFL的中級與高階語言能力目標,制定相應的教學目標,並在目標確定後通過形成性和總結性測試,在每節課與每個單元的學習過程中建立一個完整、有機的測評系統,説明學習者不斷
進步。在逐步提供中級學習者語言技巧發展所需語言任務的同時,《前進中文》課文內容設計也結合ACTFL的三種交際溝通模式,即理解詮釋、人際交流和表達演示,以及ACTFL的5C理念(即Communication溝通、Culture文化、Connection連接、Comparison對比、Community社區)。 《前進中文》除了可幫助中級中文學習者獲得全面性的進步之外,亦能培養學習者以下具體的語言能力: 1. ACTFL Oral Proficiency Interview中級語言使用者所需要的問答能力,並可處理簡單的交際任務(對於優秀學習者,高階語言使用者所需要的簡單敘述、比較
、描述等能力亦能同時培養)。 2. 理解成段的中文篇章,因此能產出句段形式的中文。 3. 建立聽力、閱讀策略,培養對不熟悉語言成分的容忍度、泛聽/讀能力,以及猜測的能力。 4. 發展並運用語言學習策略,逐漸成為獨立的中文學習者,以達到終身學習的目的。 ☉ Six Features of the Textbooks 1. This textbook series is based on results from action research done by experienced Mandarin Chinese instructors af
filiated with U.S. universities and colleges. 2. Eight thematic units run through two volumes of textbooks, covering personal, communitial, societal issues and learning tasks. 3. The design of learning tasks and assessment activities aligns with ACTFL’s proficiency benchmarks, three mode
s of communication, and 5C principles. 4. The selection of grammar and vocabulary aligns with the guidelines by HSK and Chinese Language Proficiency Test, with cross-strait differences clearly marked and listed. 5. This textbook series is designed for people from all walks of life and
college students to meet the various needs and interests of adult learners. 6. Learners will develop intermediate level oral proficiency, while establishing listening and reading strategies, and eventually become independent learners of Mandarin Chinese. 本教材六大特點 1. 本教材為北美一線中文教師行動研究成果。
2. 八大主題單元貫穿兩冊課文,由淺入深涵蓋中、高級話題與語用任務。 3. 學習活動目標、評量任務參照ACTFL的語言水準能力等級、三種溝通模式與5C理念。 4. 語言點與詞彙選擇參照漢語水準考試、華語文能力測驗的詞彙等級,且並陳兩岸差異。 5. 同時符合社會職場人士與大學生各自需求、語言能力和認知程度。 6. 發展中級口語能力,培養聽力、閱讀策略,逐步成為獨立的中文學習者。
鎳資源物質流布分析與高值化循環利用之研究
為了解決#If defined 的問題,作者陳薏慈 這樣論述:
鎳具抗腐蝕、抗氧化及催化性,廣泛應用於電鍍及合金,然由於全球為達成淨零排放及碳中和目標,各國開始致力於發展電動車,使電動車電池中鎳需求大增。我國缺乏天然鎳礦,故大多向國外進口,而為確保產業所需鎳關鍵物料得以穩定供應,本研究針對鎳資源進行物質流布分析,並探討其循環現況及進行產業鏈與循環高值化分析,以掌握我國鎳之實際流動情形,並作為我國鎳資源循環發展之參考依據。 本研究採用文獻分析與特定物質流布分析法,並透過蒐集政府及產業資訊,針對本研究之含鎳產品包括鎳氫電池、鋰電池、印刷電路板及多層陶瓷電容器,調查我國2020年鎳物質之流向及流量。根據本研究結果顯示,本研究所界定之鎳物質於2020年總進
口量為18,485,272公斤;總出口量為90,734,597公斤;總製造量為46,265,836公斤;總銷售量為46,347,877公斤;總廢棄量為52,601,056公斤,而若可將全數含鎳廢棄物循環再利用,推估出高值化潛勢約為7億7千萬元,然於鎳需求大幅增加且供應不穩定之趨勢下,應加速鎳資源高值化循環利用發展,以確保鎳資源於未來供應無虞。
