亂世人才學:動盪環境中人力管理的組織作為 / Talent Retention in Turbulent Environment : Organizing Practices for Human Resource Management within Constraints

王琳, Wang, Lin Unknown Date (has links)
全球的經營環境詭譎多變,對企業而言「變」是唯一的不變。在競爭環境中,大者恆大,資源集中在強勢企業身上,而弱勢企業只能以手邊僅有的資源去面對困境。過去的隨創(bricolage)文獻多半是分析資源匱乏時,如何重新拼湊而找到創新方案,以扭轉局勢。可是我們卻忽略,在獲取、拼湊或重組資源時,弱勢企業正遭遇重重的制約,使得資源拼湊的過程面臨各種障礙。當企業身處動盪的環境中,如何以不足的資源翻轉局勢,是劣勢創新的新課題。本研究將由人力資源的情境中去分析這個新課題。人力資源的重點是找人才、留人才、用人才,讓企業能於競爭中存活,或幸運勝出。在太平盛世時,企業會祭出各種誘因去吸引人才;可是在亂世時,強勢競爭對手各出奇招,以重金禮聘英雄,弱勢企業的誘因就不再誘人。此時,弱勢企業應如何突圍。本研究分析一家位於深圳的互聯網新創公司,在遭遇到「搶人才」的環境中,如何憑藉著有限的資源而發展出一套組織作為因應。在學術貢獻上,本案例分析企業解除人才制約的作為,跳脫誘因設計的理論,思考如何由制度的設計去產生延攬人才的激勵因子。同時,理解隨創過程中,資源拼湊之前弱勢者是如何有嶄新的角度去解讀制約,思考出化阻力為助力的解決方案,設計出回應制約的組織作為。在實務貢獻上,本研究提出在身處動盪環境之際,如何以不足的資源設計出創新的人才管理機制,由選才、育才和評量等層面去設計留才的機制。這些作為不但能做為人力資源管理的參考,其因應制約的方式更可為各類型身處劣勢的企業提供創新的思路。 / Nowadays, the global business environment becomes more and more complex and changeful. For business, ‘change’ is the fact of constant. In the competition environment, the big ones get bigger. Most resources are centralized in a few of powerful enterprises, and vulnerable others can only use less resource at hand to face the difficulty. In the past, bricolage literatures were mostly talking about how to break through dilemma and reverse the status under limited resources. However, we overlook those weak enterprises which encounter constraints when trying to obtain, integrate, or reorganize resources. That makes them confront various barriers when getting piece of resources. When the enterprise is in a turbulent situation, how to turn the tables with limited resources is a new topic. This study would analyze this new theme through the context of human resources. The key point of human resources is to find the talents, retain the talents, and assign the talents, so to make enterprises survive or lucky win from the competition. In the times of peace and order, the enterprises resort kinds of incentives to attract the talents. However, in the troubled times, strong competitors would leave no stone unturned, pay high for hiring hero. Therefore, weak enterprises’ incentives are no longer attractive. At this point, how vulnerable enterprises break through? This study analyzes how a new Internet company in Shenzhen they rely on the limited resources to develop an organization action in the "headhunting” environment. In the academic contribution, this case analysis of how the enterprise remove human resource conduct limitation, get rid of the incentive design theory, and then thinking about how to encourage the talents through the system programming. Meanwhile, to understand in the process of implement create, before piece of resources putting together, how the weak explain the constraints with a new perspective, thinking of the solution by transforming obstacles into benefits, and designed an organized behavior to respond the constraints. In the practical contribution, this study presents how to design an innovative human resource management via selecting, training, and assess employees with insufficient resources when in the turbulent environment. Not only can be the reference of human resources management, these ideas can also bring the innovative thoughts for all types of disadvantaged enterprises

TD產業的發展對標準必要專利在中國大陸之影響——以華為 VS InterDigital案及高通反壟斷案為例 / The influence of developing of Telecommunication Development industry to Standard essential patents in mainland China —— the study of antitrust case in Huawei vs InterDigital and qualcomm

王玉宇 Unknown Date (has links)
中國國內移動通信企業對於標準必要專利與美國移動通信產業知名NPE——InterDigital的初次交鋒就使得InterDigital付出了2000萬元人民幣的代價。而後,發改委對於就高通濫用標準必要專利的反壟斷調查更是開出了60.88億元的天文數字罰款單。 事實上,這些數字不僅起到了吸睛的作用,將人們的目光分分聚焦到中國的移動通信產業,同時,也因為案件發生的時間點而使得很多業界參與者猜測這樣的判決結果很可能是政府發展中國移動通信產業的政策手段。畢竟,自2000年TD-SCDMA成為世界公認的第三代移動通信標準之一以後,中國政府就打著TD產業的發展口號開始著力關注起中國移動通信市場的發展。自2008年奧運會以後,不管是銀行的放款額度還是產業政策的保護力度,都更加凸顯中國發展移動通信產業的決心。 另外,再加上近年來,各大通信巨頭在世界移動通信產業上掀起了大規模的專利戰爭,也使得人們對於專利的關注熱情愈發高漲。尤其是在移動通信產業中起到關鍵作用的標準必要專利,其價值地位也吸引了越來越多的目光。 本文試圖通過梳理TD產業政策演進的過程,來總結出中國自TD產業概念產生之後,移動通信產業發展的各階段產業狀況。再輔以華為VS InterDigital以及高通兩宗反壟斷案來探究產業政策的背後,案件結果究竟對中國移動通信市場的標準必要專利運作模式起到了怎樣的作用。 關鍵字:TD產業、標準必要專利、中國移動通信產業政策、濫用標準必要專利的制約 / For the first time that the Chinese mobile communication enterprise had a confrontation with the famous American NPE in mobile industry——Interdigital, it ended up with the result that Interdigital paid the composition of 20 million RMB. Moreover, China Development and Reform Commission gave Qualcomm a ticket of Six billion after the antitrust investigation of its abuse of Standard Essential Patents. All these numbers not only attracted public concern to the Chinese mobile communication industry, but also make some related participants thought the time of cases happened showed the sentences might be the policy methods to develop the Chinese own mobile communication industry. Since TD-SCDMA became one of the global certificated 3rd Generation Standard, Chinese government has made great efforts to develop the Chinese mobile communication under the banner of development of TD industry. After the Beijing Olympic Games in 2008, Chinese government’s determination in developing the Chinese mobile communication became greater. The evidences were the increase of banks loans and the protection of industrial methods in related filed. Furthermore, the communication giants’ pattern wars in the field of the global communication industry during recent years also raised public attention to the patterns, especially the standard essential patents which played a critical role in communication industry. This thesis attempts to reveal the industrial situations of different stages in the development of communication industry after the rise of Chinese TD industrial concept by sorting out the evaluation of TD industrial policies. Moreover, two antirust cases of HUAWEI VS InterDigital and Qualcomm shows how the sentences affected the operating mode of standard essential patents in Chinese mobile communication industry behind the industrial policies.

從優選理論之觀點研究國語變調、台語變調及國、台語夾碼時的變調 / An Optimality Theoretic Approach to Tone Sandhi in Mandarin, in Taiwanese, and in Mandarin-Taiwanese Code-Mixing

林蕙珊, Lin, Hui-Shan Unknown Date (has links)
本篇論文旨在從優選理論(Optimality Theory)之框架背景來探討國、台語夾碼(Mandarin-Taiwanese Code-Mixing)時的連讀變調現象。由於此現象之探討涉及國語及台語之變調,本篇論文亦從優選理論之觀點來探討國語三聲變調(Mandarin Tone Sandhi)以及台語的變調(Taiwanese Tone Sandhi)。 在國語三聲變調方面,由於傳統派生(derivational)模式在處理國語三聲變調時,仍遺留了些許的問題。例如,無法以一致的方式來處理non-PP和PP的變調現象。本文主要針對這個問題,重新以優選理論的角度提出解決之道。文中分別提出了一組韻律制約(Prosodic Constraint)及一組聲調制約(Tonal Constraint);根據這兩組制約,傳統派生模式所遺留下的缺失則得以獲得妥善的處理。 在台語變調方面,台語變調在傳統派生模式的探討中亦遺留下些許問題。例如,無法以一致的方式來處理non-adjunct和adjunct以及non-clitic和clitic的變調問題。本文根據優選理論,重新分析台語變調。文中分別提出了一組韻律制約及一組聲調制約;根據此兩組制約,則可以成功的免除傳統派生分析模式下的缺失。 國、台語夾碼時的變調是未曾被探討過的問題。本文先就國、台語夾碼時的變調,提出一個派生模式的分析。不過,以派生模式來處理國、台語夾碼變調時,遺留下必須限定國語變調規則和台語變調規則的運作次序這項缺點。因此,本文根據優選理論,重新分析了這個變調現象,並提出了一組聲調制約;這組聲調制約,配合國語及台語的韻律制約,得以成功的處理傳統派生模式所遺留下的問題。 / The present thesis is mainly devoted to the research issue of tone sandhi in Mandarin-Taiwanese code-mixing using an Optimality Theoretic (OT) Approach. Since the study of this code-mixed tone sandhi necessarily involves the tone sandhi rules of Mandarin and of Taiwanese, the tone sandhi phenomena in Mandarin and in Taiwanese are carefully discussed under OT as well. Tone sandhi in Mandarin has been widely studied by many Chinese linguistics under the derivational approach. This thesis argues that the previous analyses to Mandarin tone sandhi are inadequate and that an Optimality Theoretic approach is needed to account for tone sandhi in Mandarin. The inadequacy of the previous analyses comes from the common failure of offering a uniform solution to account for non-PP and PP word stings in Mandarin. Based on the Optimality Theory, this thesis proposes two sets of constraints to account for Mandarin tone sandhi; one is the prosodic constraints set and the other is the tonal constraints set. This thesis proves that these two constraints can successfully get rid of the problem left by the derivational tradition. Tone sandhi in Taiwanese is also widely studied by many Chinese linguistics under the derivational approach. This thesis argues that the previous analyses to Taiwanese tone sandhi are inadequate and that an Optimality Theoretic approach is needed to account for tone sandhi in Taiwanese. The inadequacy of the previous analyses comes from the fact that Taiwanese word strings with non-adjunct and adjunct structures as well as with non-clitic and clitic structures fail to be accounted for using a uniform solution. Based on the Optimality Theory, this thesis proposes two sets of constraints to account for Taiwanese tone sandhi; one is the prosodic constraints set and the other is the tonal constraints set. This thesis proves that these two constraints can successfully get rid of the problem left by the derivational tradition. Tone sandhi in Mandarin-Taiwanese code-mixing is a phenomenon that is very interesting but has not been studied before. This thesis thus offers a derivational analysis to this tone sandhi phenomenon first, where it is found that (1) in Mandarin-Taiwanese code-mixing, a Mandarin base tone can trigger Taiwanese tone sandhi and a Taiwanese low tone can trigger Mandarin tone sandhi, (2) in Mandarin-Taiwanese code-mixing, the Mandarin tone sandhi rule is sensitive to all and only the Mandarin tone sandhi domain and the Taiwanese tone sandhi rule is sensitive to all and only the Taiwanese tone sandhi domain, and (3) in Mandarin-Taiwanese code-mixing, the Taiwanese tone sandhi rule must apply before the Mandarin tone sandhi rule to derive the tonal output. However, since the demand for an extrinsic rule order between the tone sandhi rules of Mandarin and Taiwanese is inadequate, the tone sandhi phenomenon is reanalyzed under the framework of the Optimality Theory. A set of tonal constraints is proposed. According to the tonal constraints set, the inadequacy left by the derivational approach is successfully avoided.

以優選理論分析兩個客語方言之連讀變調 / An Optimality Theory Approach to the Tone Sandhi in Two Hakka Dialects

陳煒翰, Chen, Wei Han Unknown Date (has links)
本論文以優選理論分析六家饒平客語和寧都田頭客語雙音節詞之連讀變調,並藉由聲調內部結構說明變調的動機。在六家饒平客語方面,主要是呈現位置變調(positional tone sandhi),較有標(more marked)的聲調位於前字時發生變調。另外,此方言的陽平和陽去因歷史演變,兩者的本調(citation tone)同為HH,但兩者因不同的變調形式而產生不同的變調(sandhi tone)。陽去的變調形式為位置變調,而陽平的變調形式為環境變調(contextual tone sandhi)。本文採用聯合制約(Local Constraint Conjunction)捕捉環境變調制約運作的環境。另外,運用「詞素特定音韻」(morpheme-specific phonology)標記聯合制約,解釋陽平和陽去不同的變調規則。在寧都田頭客語方面,變調受詞法結構影響,且兩個音節皆有可能發生變調。本文利用標記制約理論(indexed constraints approach)解釋不同結構的變調情形。另藉由位置信實制約不同的排序,嘗試說明聲調的保留屬於類型差異(typological differences)。而此方言的變調類型包含位置變調和環境變調,同樣要求較有標的聲調改變,並使用聯合制約說明在環境變調的情況下制約運作的環境。 / This thesis investigates the tone sandhi in Liujia Raoping Hakka and Ningdu Tiantou Hakka under the framework of Optimality Theory. The internal structure of the tone reveals the motivation and the mechanism of tone sandhi. In terms of the tone sandhi in Liujia Raoping Hakka, the universal tonal markedness tendency could be regarded as the motivation triggering the positional tone sandhi in the left syllable. Moreover, the morpheme-specific phonology is adapted to account for the tone sandhi of historical merged tones, Yangping and Yangqu. Yangping and Yangqu are both high level tones; however, they display different tone sandhi patterns. Yangping displays the contextual tone sandhi whereas Yangqu displays the positional tone sandhi. Local conjunction constraints are posited to restrict markedness constraints to specific contexts in order to account for the mechanism of contextual tone sandhi. On the other hand, in terms of the tone sandhi in Ningdu Tiantou Hakka, the tone sandhi is construction sensitive and takes place in both syllables. The indexed constraint approach is adopted to explain the tone sandhi in different constructions. In addition, the preservation of tone is argued to be the typological difference according to different rankings of the positional faithfulness constraints. Finally, the tonal markedness tendency motivates the positional tone sandhi and the conjoined constraints are posited to govern the contextual tone sandhi in this dialect.

電刺激大鼠側韁核對區辨性低頻操作式制約行為的影響 / The effects of electrical stimulation in the lateral habenula on operant behavior maintained by the differential reinforcement of low-rate (DRL) schedule of reinforcement in the rat

林禧岳 Unknown Date (has links)
透過神經科學的研究,對於大腦的行為功能已有一定的認識,不同於以往的認識,目前認為神經行為機制不只由單一腦區或單一神經化學系統所調控。深部大腦電刺激經常被用來研究特定腦區的行為功能。但是,深部大腦電刺激的作用機制仍然不清楚。最近幾年臨床研究發現,利用電刺激在側韁核成功的治療憂鬱症患者。然而,目前認為側韁核與多巴胺系統互為負回饋作用,共同參與在動機行為的酬賞反應中。本實驗室先前的研究顯示,破壞韁核造成區辨性低頻操作式制約行為 (簡稱DRL行為)學習的障礙,然而,電刺激在側韁核造成DRL行為表現的結果還是未知的。所以,本實驗主要以電刺激在側韁核觀察大鼠行為上的改變,探討側韁核在行為上參與的功能。實驗一的結果顯示電刺激在側韁核並不影響自發性運動能力,在不同電流強度的刺激下也不會影響。實驗二的結果顯示電刺激在側韁核造成DRL 15秒的行為有類安非他命效果之行為表現,在高頻率電刺激有較顯著類安非他命的效果。實驗三的結果顯示電刺激在側韁核造成DRL 15秒的行為之影響,會被多巴胺受體抑制劑所抵消,而單獨注射巴胺受體抑制劑並不影響DRL 15秒的行為。實驗四的結果顯示電刺激在側韁核造成DRL 15秒的行為之影響,不會被正腎上腺素受體抑制劑所抵消。實驗五的結果顯示電刺激在側韁核造成DRL 72秒的行為之影響並不如DRL 15秒的行為顯著。實驗六的結果顯示電刺激在側韁核並不會造成大鼠無法區辨酬賞的量。綜合而言,側韁核在動機行為的角色,是透過影響多巴胺系統造成行為的改變。 / Behavioral function of the brain has been studied in neuroscience and progressively accumulated informative data to reveal the neurobehavioral mechanisms. It is now realized that those underlying mechanisms of behaviors is not as such simple as previous thought of limiting only in one locus of the brain or solely by one neurochemical system. The deep brain stimulation is usually used to study the behavioral function of specific brain regions. However, the mechanism of the deep brain stimulation is still unclear. The previous study has shown that electrical stimulation of the lateral habenula (LHb) successfully treated depression symptoms in the patients. It is proposed that an inhibitory role of LHb on the mibrain dopamine (DA) system which mediates the reward-related behavior. A previous study of this lab showed that lesion of habenula impaired the acquisition of differential reinforcement of low-rate responding (DRL) behavior. But, the effect of LHb stimulation on the DRL behavior is still unclear. To determine the functions of LHb involving in the behavior, the electrical stimulation was applied in LHb to observe the behavioral change of rats. The results of Experiment 1 showed that the LHb stimulation had no effect on locomotor activity. In Experiment 2, the LHb stimulation was shown to affect DRL 15-s behavior, which effects were similar to those affected by amphetamine. Experiment 3 showed that the DA receptor antagonists reversed the effects of LHb stimulation, while experiment 4 showed that norepinephrine (NE) receptor antagonists had no reversal effect on DRL 15-s behavior. In Experiment 5, the amphetamine-like behavior induced by LHb stimulation had subtle effects on DRL 72-s behavior. Experiment 6 showed that the LHb stimulation had no effect on a discrimination task. These data suggest that the LHb modulating DRL behavior is DA-dependent.

國際貨幣基金的組織與功能 / The Organization and Functions of the International Monetary Fund

王瑤瑛, Yao-ying Wang Unknown Date (has links)
布列敦森林機制的成形與運作是基於國際社會對一九三0年代經濟大恐慌所記取的歷史教訓。國際社會要捨棄「以鄰為壑」的歷史錯誤,期以國際協調與合作解決國際經濟秩序不穩定的問題。但是在建立布列敦森林機制的過程中與布列敦森林機制的運作上,顯現出國際政治權力與國家利益才是最重要的考量。美國以其在兩次世界大戰中發展出的國力,主導了布列敦森林機制的設計,將大部分的國家納入此項體系中,並以此體系中的規範、準則來約束所有成員的行為。透過此機制的槓桿運作,美國得以將其在政治上與經濟上的力量發揮到極至,從而維護美國繼續作為霸權國的國家利益。布列敦森林機制成為戰後國際合作的基礎架構,會員國所簽訂的國際貨幣基金協定條款成了體系成員的行為準則。制約條件與監督會員國的經濟政策之權是國際貨幣基金兩項最重要的武器。然而,制約條件所產生的政經效應,卻讓國際貨幣基金倍受批評。影響制約條件成效不彰的原因包含有國際貨幣基金的組織結構因素、國際環境因素與執行制約條件的國家的內部因素。國際社會將所有的責任都歸於國際貨幣基金,實在是隔靴搔癢,同時也無助於解決當今資本全球化所引發的問題。 目  錄 序言 壹 圖表目錄 參 第一章 緒論 1 第二章 國際貨幣基金之成立 4 第一節 布列敦森林機制的起源 4 第二節 布列敦森林機制前的國際貨幣體系 9 第三節 懷特方案與凱因斯方案 12 第四節 小結 17 第三章 布列敦森林機制的制度分析 21 第一節 國際貨幣基金的制度 21 第二節 國際貨幣基金的組織 26 第三節 美國霸權與布列敦森林機制 34 第四章 國際貨幣基金角色的轉變 50 第一節 國際經濟環境的變遷 50 第二節 國際貨幣基金協定條款的修訂 54 第三節 特別提款權的運作 59 第四節 國際貨幣基金的監督功能 61 第五章 國際貨幣基金的制約條件 67 第一節 什麼是制約條件 67 第二節 制約條件的發展 71 第三節 制約條件與調整政策 76 第四節 制約條件的政經效應 79 第六章 一九八0年代的拉丁美洲債務危機 92 第一節 拉丁美洲債務危機的起源 92 第二節 處理拉丁美洲債務危機的國際行動 96 第三節 處理拉丁美洲債務危機的成效與政經意涵 102 第七章 一九九七年東亞金融危機 111 第一節 東亞金融危機的起源 111 第二節 東亞國家的政治經濟結構 117 第三節 處理東亞金融危機的國際行動 119 第四節 國際貨幣基金穩定方案的檢討 123 第五節 小結 132 第八章 結論 138 參考書目 143 圖表目錄 圖 圖3-1 國際貨幣基金組織結構圖 45 表 表6-1 拉美國家的貿易平衡、經常帳與資本基本轉移 的情況,1977—1987 105 表6-2 接受IMF融資計畫的拉美國家之經濟表現 105 表6-3 接受IMF融資計畫的拉美國家之債務情況 106 表7-1 泰國、印尼與南韓三國外匯存底的變動, (1997年6月—19982月) 112 表7-2 東亞四國的債務情況 114 表7-3 東亞四國的經濟表現,1997—1999 131
