個人、國家與世界:論約翰彌爾的公眾參與理論

黃培維, Huang, Pei Wei Unknown Date (has links)
本文從個人、國家和世界三個層面來重新建構約翰彌爾的公眾參與理論。其公眾參與理論包含了公民精神和公民參與這兩個部份。公民精神主要強調合作的精神,天才和菁英組成的知識階級公民必須和其他大眾階級的公民合作,才可以減少痛苦得到快樂,唯有合作才能讓每個人可以充分運用到自己的能力,享受到高級樂趣,得到個人的幸福,也讓社會獲得更多的效益。合作的精神必須透過實際的參與才可以學習,因此參與本身具有教育的功能。彌爾認為公民精神必須透過國家內部的地方和中央雙軌式的參與才可以培養,由知識階級擔任引導的角色,在參與過程中協助大眾階級的學習。這種方式擴展到世界上就是文明國家對野蠻國家的帝國主義干預。殖民地不適用於不干預原則,因為他們必須透過和統治者的合作,才能學習如何運用自己的能力來得到幸福。 / This study tries to reconstruct John Stuart Mill’s theory of public participation from three perspectives: individual, national and international. This theory consists of an account of citizenship as well as an account of citizen participation. At the core of Mill’s idea of citizenship is cooperation between intelligent citizens, which include geniuses and elites, and the masses. By cooperation, people can make best use of their capacities, and attain their own higher pleasures and ultimately happiness. This citizen spirit can only be cultivated through political participation, and thus it has implications on education policy. The purpose of educating the masses is to help them develop and use their intellectual ability, and to do so intelligent citizens must assume the role of leading their fellow citizens with regard to political participation. And only from this perspective can we truly understand Mill’s theory of international intervention – or liberal imperialism, according to which civilized states are allowed to intervene the barbarian ones. Colonized population must cooperate with and learn from their rulers – that is to say, to conduct their own experiments in living under their colonizer’s tutelage.

探討大白鼠之風險選擇行為之神經機制 / Investigation of neural mechanisms of risky choice behavior in the rat

楊仁豪, Yang, Jen Hau Unknown Date (has links)
「風險決策」行為非常普遍的存在於吾人之日常生活中,而選項所帶來的風險和獎勵是吾人進行決策時的重要考量因素。風險選擇的適當與否,對於個體的生存扮演著相當重要的角色。在以往的文獻中,對於決策的行為歷程已有所關注及探討,但對於風險選擇行為的神經生理機制迄今未明。本研究藉由大白鼠於T字迷津中,選擇確定之低酬賞或高不確定性之高酬賞的行為表現,進行風險選擇行為的探討。本研究中以兩項主要實驗,探討風險選擇行為之神經行為機制。實驗1a中,確定之低酬賞端固定呈現1顆食物粒,而高不確定性之高酬賞端則同時操弄酬賞物機率(50%、25%及12.5%)以及酬賞物的量(2、4及8顆),以系統性地檢驗期望值(0.5、1和2)於此風險選擇行為中扮演的角色。行為結果顯示當風險較低時,大白鼠會選擇高不確定性之高酬賞端;而風險較高時,則轉為選擇確定之低酬賞端。實驗1b中,系統性地施打不同劑量之安非他命,探討多巴胺系統在此風險選擇行為中之機制。實驗結果顯示施打安非他命後,大白鼠表現出相對地追求風險之行為,亦即選擇高不確定之高酬賞端之比例顯著高於控制組。實驗2中,藉由毀除大腦特定部位(依核、背外側之紋狀體、眶前額皮質、內側之前額皮質),檢驗風險選擇行為之神經基礎。毀除後之結果顯示,僅有依核受到毀除之大白鼠表現出相對地趨避風險之選擇行為。綜合以上結果,本研究建立之風險選擇行為與多巴胺有關,而依核在此行為歷程中扮演重要的調節角色。 / Many decisions people make every day involve uncertainty where both risks and rewards associated with each option need to be considered. Behavioral performance associated to risk-based choice appears wildly over the lifespan, and the fitness of risky choice behavior plays an important role in individual survival. Despite a growing body of research has focused to investigate the neurobiology of decision making, little is known about the neurobehavioral mechanisms of risky choice behavior. Based on a pilot work, this study used a T-maze to study decision under a probability-based risk in the rat. The subject was assessed on making choice to obtain either a large reward associated with risk of non-reward “empty” or a small reward ensured for every entry. Two experiments were conducted in this project to investigate neurobehavioral mechanisms of probabilistic risky choice behavior. In Experiment 1a, probabilistic risky choice behavior was systemically assessed under three expected values (0.5, 1.0, and 2.0) by manipulating the probabilities of reward presence (50%, 25%, and 12.5%) and the reward magnitude (2, 4, or 8 pellets) in the probabilistic high reward (PHR) arm. Behavioral data showed that the subject chose the probabilistic high reward in a lower risk condition but would shift to the choice of certain low reward (CLR) as the risk is increased. In Experiment 1b, the dose effects of amphetamine on this probabilistic risky choice task was tested to verify whether the dopaminergic mechanism was involved. Amphetamine, presumably activating brain dopamine systems, produced a relatively risk-seeking effect on the present behavioral task. In Experiment 2, the excitoneurotoxic lesion was conducted in the nucleus accumbens, the dorsolateral striatum, the orbitofrontal cortex, and the medial prefrontal cortex to examine the neural substrates for this probabilistic risky choice behavior. The results showed that the lesion of the nucleus accumbens significantly produced a relatively risk-averse effect on the present behavioral task, as compared to the lesions made on the other three brain areas. In conclusion, the probabilistic risky choice behavior established in the present study is dopamine dependent. And, the nucleus accumbens plays a major role of mediating this behavioral processing.

探討安非他命引發的制約場地偏好行為的分子機制:以大腦神經滋養因子為例 / Investigation of molecular mechanisms on amphetamine induced conditioned place preference: the role of Brain-Derived Neurotrophic Factor (BDNF)

張庭源 Unknown Date (has links)
制約場地偏好行為為研究藥物成癮的常用模式之一,對於其行為表現及再復發的神經機制,多巴胺系統佔有舉足輕重的地位。而大腦神經滋養因子(BDNF)與多巴胺系統密切相關,影響其神經元可塑性。故本研究以BDNF來作為目標分子,進行一系列的實驗探討制約場地偏好的神經機制。實驗一A以不同劑量安非他命建立制約場地偏好行為,並分析其BDNF mRNA的表現量。實驗結果顯示1 mg/kg安非他命能夠引發制約場地偏好行為,但是對於內側前額葉、紋狀體、依核、背側海馬迴、杏仁核等五個區塊的BDNF mRNA無顯著的影響效果。實驗一B再次確認實驗一A的結果,顯示俱有安非他命引發制約場地偏好行為的受試,其大腦五個區塊BDNF mRNA沒有顯著的變化。實驗二探測制約場地偏好行為再復發對於相同的五個區塊BDNF mRNA變化。結果發現0.75 mg/kg安非他命能誘發制約場地偏好再復發行為,並且能引發內側前額葉中BDNF mRNA的增加,但對其餘四個區塊則無明顯的影響效果。實驗三以單次注射安非他命探討對於BDNF mRNA是否有立即性的影響,結果顯示五個區塊皆無明顯的變化。實驗四以安非他命引發的行為致敏化反應為行為模式,偵測BDNF mRNA的表現情形。結果發現藥物制約配對組與單次注射安非他命組在活動量上無顯著的差異,顯示出無行為致敏化反應的發生。檢驗五個區塊BDNF mRNA的表現,亦沒有發現明顯的改變。綜合以上的實驗結果,本研究得到安非他命制約場地偏好再復發行為,會伴隨內側前額葉BDNF mRNA的增加。而單獨的安非他命引發制約場地偏好行為,並不會改變BDNF mRNA。這些結果顯示BDNF參與在較複雜的制約學習行為歷程,而不是在單獨的藥物注射或與環境配對的制約過程。 / Conditioned place preference (CPP) is widely used as an experimental behavioral model in the study of drug addiction and reward learning. Brain dopamine systems play an important role to drive the CPP performance and its relapse. Brain-derived neurotrophic factor (BDNF) is closely related to dopamine system that can promote neuron plasticity involved in certain types of behavior. Taking BDNF as the target molecule, this project conducted a series of experiments to delve into the neural mechanism of CPP. Different doses of amphetamine on the CPP behavior were assessed in Experiment 1A, and BDNF mRNA was tested after CPP test. The results show that 1 mg/kg amphetamine significantly induced CPP, but no significant effect on BDNF mRNA in any of five brain areas tested, including medial prefrontal cortex, striatum, nucleus accumbens, dorsal hippocampus and amygdala. The results of Experiment 1A was further confirmed by Experiment 1B, indicating no significant change on BDNF mRNA in five brain areas of rats with significant amphetamine-induced CPP. Experiment 2 examined the effects of CPP relapse and tested BDNF mRNA in the aforementioned five brain areas. The results show that 0.75 mg/kg amphetamine significantly induced CPP relapse and also increased BDNF mRNA level in medial prefrontal cortex. Such an increase of BDNF mRNA was not observed in any other four areas. Single acute injection of amphetamine was administered in Experiment 3 to delve into the possible immediate drug effect on BDNF mRNA. Its results show no significant change on five brain areas following this acute drug treatment. Experiment 4 used amphetamine-induced behavioral sensitization as a behavioral mode to determine the expression of BDNF mRNA. The results show no significant difference both for amphetamine-paired group and acute amphetamine group on locomotion, that indicated no behavioral sensitization formed in this test. There was no significant difference in the expression of BDNF mRNA in five brain areas. These results indicate that amphetamine-induced CPP relapse, but not CPP performance itself, is accompanied by the increase of BDNF mRNA level in medial prefrontal cortex. These findings indicate that BDNF is involved in place conditioning formed by psychostimulant drug when it is reinstated after extinction, rather than by a solitary drug injection or a relatively simple conditioning process by pairing drug with the environmental context.

服務核心、服務傳送系統與績效關係之研究 : 以台北市服飾零售業為實證對象

魏正元 Unknown Date (has links)
摘要 分類是研究的第一步,服務業理必須基於有意義的分類,才 可能提出規範性的結論。此外,服務業的無形產出,必須透過細緻的 服務傳送系統設計來傳遞給顧客。因此服務業的研究首要工作,在從 抽象的層次中提出對服務業無形特性的有效分類。經由文獻檢討及實 務觀察,本文提出三項服務業的產出分類構面:經濟性、社會性及心 理性利益,稱之為服務核心。以此三構面將台北市的服飾零售業分為 四種類型:經濟心理性、心理性、混雜性及經濟性零售店。各類型零 售店中較績優者,相互之間服務傳送系統的差異非常明顯,顯示績效 的殊途同歸性是明顯的。用一類型零售店組內的比較分析中,以類神 經網路求得影響績效最重要的服務傳送系統項目:經濟心理性最重要 的活動與商品無直接的關連;心理性零售店最重要的是人員專業性與 商品風格與品味;經濟性零售店的服務傳送系統則是愈簡單愈好。文 末並提出相關的討論是建議。 / ABSTRACT keywords: service industry, service core, service delivery system, retail industry, neural network Classification is the first step for research. Normative suggestions cannot be provided unless meaningful classification is available in service management. Meanwhile, intangible output in service organizations usually is transferred to customers through delicate service delivery system. Therefore the primary task in service management research is to devise efficacious, theoretical classifications to govern inherent intangibility in service management. Through literature review and field study, this paper proposed three classifying dimensions for fashion retailing, which were termed service cores consisting of economic , social , and psychological benefits. Based on these three dimensions, four types of retailing firms were derived with clustering analysis: eco-psychological, psychological, and economic types. Between groups, better performers were extracted to compare with each other, which demonstrated the significances of equifinality towards performance and differences between these four retailing types. Within groups, neural network analysis was employed to determine important factors in service delivery system. In eco-psychological type, important factors were irrelevant to merchandises. Professional salespersons and special merchandise were critical to psychological stores. Better economic stores were all rated low in most delivery activities. Relevant suggestions and discussions were given to conclude the findings.

李彥廷 Unknown Date (has links)
GPS 單點定位或稱絕對定位,傳統上使用虛擬距離觀測量,容易受到 電離層延遲影響,導致定位精度較差。因此,本文的目的為構建即時的區 域性電離層模型,以便能夠即時減弱電離層延遲量,提高單頻GPS 單點定 位的精度。 構建電離層模型的方法有很多種,而運用類神經網路為可能方法之一, 但是, 國內較少人探討。本研究嘗詴使用倒傳遞類神經網路(Back-propagation Artificial Neural Network),構建即時的區域電離層模型,藉由選擇適當的神經訓練函數及隱藏層神經元,利用過去收集的已知參考站的雙頻GPS 資料,計算電離層延遲量,訓練類神經網路,直到精度合乎要求;再以檢核站GPS 資料,檢驗類神經網路預測電離層延遲的功效。 採用的實驗資料為臺南市政府e-GPS 系統所提供六個測站,2008 年1 月3 日到1 月5 日的GPS 資料,計算測站與GPS 衛星連線中假想的電離層 薄殼交點—電離層穿透點(Ionosphere Pierce Point, IPP)之地理位置(緯度φ、經度λ),及太陽黑子數(sunspot numbers)等當作輸入值,IPP 的垂直電離層延遲當作輸出值,測詴包含單日、兩日以及不同的資料型態(IPP 點、網格點)等情況訓練類神經網路,藉由相對應的驗證資料,檢驗類神經網路的功效,最後將類神經網路的預估成果與全球電離層改正模型、雙頻GPS 資料計算的電離層延遲相比較,並根據改正率與統計特性,評估類神經網 路構建出的區域性電離層模型的成效。 由實驗成果顯示,構建的即時區域性電離層模型的標準差可小於±3TECU,並可改正約80%的電離層延遲誤差,故以類神經網路可有效的構 建出區域性的電離層模型。 / The conventional single point positioning using GPS pseudo rangemeasurements, are vulnerable to ionospheric errors, leading to poor positioningaccuracy. Constructing a real-time ionospheric model is one of the methods that can reduce the ionospheric errors and improve the single point positioning accuracy. Although there are many methods to construct regional ionosphere model,using artificial neural network (ANN) to construct a real-time ionospheric model is less to be mentioned. This study used back-propagation artificial neural network to estimate a regional real-time ionospheric model by selecting the appropriate training functions and the number of hidden layers and its’ nodes. The neural network had to be ‘trained’ by the computed TECs from reference stations’ duel-frequency GPS data until the required accuracy was achieved. The experimental data are collected from 6 e-GPS stations of Tainan city government on January 3 to January 5, 2008. The input values for the ANN includ the geographical location of the ionosphere pierce point (IPP) and solar activity (sunspot number). The output value are those IPPs’ vertical total electron content (VTEC). Different times range and data types (IPPs’ or raster data) for the impact of the ANN are tested. And then compared to Klobuchar model and global ionopheric model, according to the correct rate and the ΔTEC statistic table decide the effectiveness of ANN. According to the test results, the regional ionopheric model constructed by ANN can corrected 80% of the ionospheric errors, the standard deviation of ΔTEC is less than ±3TECU.

資料採礦於乘用汽車產業之顧客關係管理研究 / A Study of Data Mining on Automobile Industry’s Customer Relationship Management

陳竑廷 Unknown Date (has links)
國父 孫中山先生曾說:『民生的需要,從前經濟學家都說是衣、食、住三種。照我的研究,應該有四種:於衣、食、住之外,還有一種就是行。』,在各種交通工具中,最普及的就是汽車。汽車由貴族地位的象徵,發展至福特汽車公司一家獨大,最後演變為各大汽車品牌的競爭。更因消費者意識的改變,購買汽車時考慮的不再僅是量產速度、購買價格。在現今生產技術成熟,沒有一家汽車公司具壓倒性優勢的情況下,品牌的因素將會是消費者進行購買決策時一個重要的指標。 本研究欲透過國內六大汽車品牌之顧客關係資料,利用資料採礦模型,瞭解品牌形象、廣告印象及人口統計變數與購買意願之關係,進一步探討各汽車品牌之消費者忠誠度、客群分布與品牌差異,期能在汽車品牌公司百家爭鳴情況下,分析出消費者於不同汽車品牌之品牌知覺,提供汽車品牌之購買意願模型與後續研究參考。

14與18個月嬰兒理解他人的溝通意圖 / Fourteen- and Eighteen-Month-Old Infants Understand Others' Communicative Intents

簡嘉慧, Chien, Chia Hui Unknown Date (has links)
理解他人的意圖,指的是理解他人的行為背後蘊含著一個希望達成的具體目標,是嬰兒社會認知發展中一項重要的基礎能力,而此能力的發展應具有跨文化一致性。然而,過去國內外研究結果顯示,台灣與西方嬰兒透過非語言線索理解他人溝通意圖的能力有明顯的落差。因此,本研究為了瞭解台灣嬰兒理解非語言線索的溝通意圖之能力,並找出可能導致上述不同研究結果的作業差異原因,將藉由兩項實驗來探討此議題。實驗一以藏物遊戲為實驗派典,觀察14與18個月的台灣嬰兒,在「眼神注視」、「手指指示」及「意圖性語音」三種非語言線索情境中,是否可藉由對線索溝通意圖的理解而找出隱藏的意圖目標物。結果發現14個月的台灣嬰兒,可理解他人「手指指示」線索的溝通意圖,但無法理解「眼神注視」與「意圖性語音」線索的溝通意圖,而18個月的台灣嬰兒則是可理解他人「眼神注視」線索的溝通意圖,但卻無法理解「手指指示」與「意圖性語音」線索的溝通意圖。為了排除藏物容器設計可能造成的干擾因素,實驗二調整了藏物容器裝置,以同樣的實驗方式觀察台灣嬰兒理解他人非語言線索溝通意圖的能力。結果發現,14個月的台灣嬰兒仍只能藉由「手指指示」線索理解他人的溝通意圖,但18個月的台灣嬰兒則已可透過「眼神注視」、「手指指示」及「意圖性語音」三種非語言線索理解他人的溝通意圖。此結果說明,台灣與西方嬰兒透過非語言線索理解他人溝通意圖的能力大致相同,即嬰兒理解他人溝通意圖的能力確實具有跨文化一致性。 / Understanding the intents of others, to understand the existence of specific goals that people wish to achieve from their behaviors, is one of important basic abilities in the social cognitive development of an infant. The developmental time frames of such ability should be the same across cultures. However, previous domestic and overseas studies proposed that the abilities of infants to understand the communicative intents of others through nonverbal cues are different between Taiwanese and western cultures. Hence, in this study, two controlled experiments were conducted to explore the abilities of Taiwanese infants to understand the communicative intents of others through nonverbal cues and the factors of the tasks that may cause different results between domestic and overseas studies. In the first experiment, an experimenter used the cues of gazing, pointing, and intentional vocalization in a hiding-game task to examine whether fourteen- and eighteen-month-old Taiwanese infants could infer communicative intents expressed in the three nonverbal cues and find the hidden objects. Results showed that 14-month-old Taiwanese infants could only follow the cue of pointing to find the hidden objects, but not gazing or intentional vocalization. And 18-month-old Taiwanese infants could find the hidden objects by following only the cue of gazing. To exclude the possible interferences of the target containers, the experimenter used the same procedures and settings in the second experiment as the first one, but modified the containers to clarify the hiding-game task. Results showed that 14-month-old Taiwanese infants could still follow only the cue of pointing to find the hidden object, but 18-month-old Taiwanese infants successfully followed all three types of cues. Based on these findings, the abilities of infants to understand others’ communicative intents by following nonverbal cues are the same in Taiwanese and western cultures. That is, the developmental time frames of the abilities of infants to understand the communicative intents through nonverbal cues are the same across different cultures.
