本研究以溪洲部落拆遷政策變遷為個案研究，瞭解「代表性官僚」在實務上如何運作，以及他們在現實的政策環境中如何自處，藉由深入的探討來發掘「代表性官僚」的更多可能，讓他們發揮積極代表性的功能。研究方法以深度訪談為主，在不足處再佐以官方新聞稿及國內報紙新聞資料，進行5位受訪者，共計6次訪談，研究範圍自2007年9月至2011年5月止。 本研究結果發現，因個案牽涉層級太高，臺北縣原民局的行政決策空間有限，在個人因素方面，「代表性官僚與代表團體間擁有共享的價值觀與信念」、「代表性官僚改變政策標的之行為」、「代表性官僚本身對其代表性的認同程度」等對代表性官僚的決策與執行有影響；在結構因素中「行政裁量權的多寡」與「外在政治環境」對代表性官僚的決策與執行有影響，較具體是反映在專業與資源不足、社會運動蓬勃、媒體與政治力介入、學者專家介入等因素。除了上述的影響因素之外，本研究亦發現不同行政人員的信仰、生活經歷、工作經歷等亦會影響行政人員處理相關事務的態度。此外，研究發現認為原住民族身分的行政人員如與政策標的屬於同一族群，則較能發揮文化、語言等優勢進行溝通協調工作，而原民住族在有困難時，也會習慣向自己的原民行政體系尋求協助，顯見「代表性官僚」的存在有其功能。但值得一提的是，非原住民族的行政人員也能夠透過與族人的長期互動來獲得族人的認同，因此，從處理原住民族事務的觀點來看，不論行政人員是否屬於原住民族，培養「原民意識」皆是必須的。 此外，本研究建議：第一，原民體系應增加人力與專業等資源，在政策推動上爭取主導權，避免成為自我限縮的官僚；第二，處理原住民族事務需要「原民意識」的培養，增加行政人員的內在動力；第三，為因應愈來愈多的都市原住民人口，中央原民會應主動進行全盤的政策規劃和立法相關準備工作，讓原住民族的利益能夠獲得立法保障，減少政黨輪替所帶來的影響，最後應有原住民族公共利益的產生制度，並增加族人對於原住民族代表性官僚的課責管道，以回應政策需求。 / This study is a case study about the relocation policy negotiation with Shijou Tribe, in order to understand how "Representative Bureaucracy" works in practice, as well as the real policy environment, and to discover the "representative bureaucracy" more likely to enable them to play an active representative functional . the main research method is in-depth interviews, the five respondents, a total of six interviews, and then combined with the official press releases and newspapers from September 2007 to May 2011 only. The study found that because the case involves high-level, Council of Indigenous Peoples Bureau, Taipei County executive decision-making space is limited. In personal factors, "between representative bureaucrats and representative groups with shared values and beliefs," "representative bureaucrats to change its policy subject of conduct "," representative bureaucracy itself, the recognition of their representative, " influence representative bureaucrats on the decision-making and implementation. In the structure factors, "the amount of administrative discretion" and "external political environment" influence representative bureaucrats on decision-making and implementation, more specifically reflected in the lack of expertise and resources, social movements, media and political forces involved, scholars expert intervention. Except the above factors, the study also found that the administrative staff of different beliefs, life experiences, work experience and other administrative staff will also affect the attitude of dealing with relevant affairs. In addition, the study found that Aboriginal identity and policy underlying executive officer of the same ethnic group, are more able to play culture, language and other advantages of communication and coordination, and the original people also used to their own administrative systems of Indigenous Peoples for assistance, which shows that the existence of "representative bureaucracy" has its functions. But it is worth mentioning that non-Aboriginal executives can also via the long-term interaction with the tribe to get the tribe recognized, therefore, deal with Aboriginal affairs from the point of view, regardless of whether they are Aboriginal administrative staff, developing a "sense of the original people" are necessary. In the end, this study suggests that the original system should increase professional ability and other resources, to avoid becoming a self-limited reduction of bureaucracy; In addition, increase administrative personnel intrinsic motivation; Finally, in response to an increasing number of urban Aboriginal population, Council of Indigenous Peoples, Executive Yuan should adjust overall policy planning and legislation related to preparatory work for the interests of indigenous peoples to obtain legislative protection, reducing the impact of politics. On the other hand, indigenous peoples should have the system for the public interest and increase the representative bureaucrats accountability.

本研究使用資料包絡分析法衡量NBA球員之績效值，並探討球員在簽訂複數年合約前後與績效之關聯性，是否有Stiroh(2002)提出之合約年效應，並進而比較NBA官方提供績效值與DEA法計算出之球員績效值何者對於球員薪資具有較佳的解釋能力。 本研究取用2000年至2011年共11年間曾經歷合約到期並再次向球團簽訂複數年合約的184名球員做為樣本；實證結果發現，在控制年齡、年資、提前續約與否、球員位置及先發球員與否後整體技術效率方面及球員每分鐘平均績效值顯示在球員簽約前績效有顯著提高之現象； NBA官方提供績效值與純技術效率簽約前後係數也是負的，雖然未達到統計上顯著水準，因此，本研究結果顯示NBA球員在簽約新約前的確有合約週期現象，亦即為爭取較佳合約球員在簽約前會刻意表現較佳之績效。 此外，根據Vuong Test比較NBA官方提供績效值與DEA法計算出之績效值和球員每分鐘績效值與薪資關聯性的測試結果，顯示由官方提供之績效值對薪資關聯性較高，說明目前NBA官方提供之績效值仍然是球團用來與球員薪資的談判重要參考指標之一。 / The research applies Data Envelopment Analysis to examine the NBA players’ efficiency performance before and after signing a new multi-year contract, and whether there exists the Contract Cycle Effect that suggested by Stiroh (2002). The research also tries to compare NBA efficiency score and DEA efficiency score to test which has a higher association with salary. The samples selected 184 NBA players who signed a new multi-year contract from 2000 to 2011. After controlling the players’ age, seniority, extension, position and starting or not, the empirical results denote that DEA total efficiency score and the NBA efficiency per minute indicate a higher efficiency score before signing a new contract, The NBA official efficiency score and DEA technical efficiency score also reveal a negative coefficient before and after new contract singed, although the statistical test didn’t reach the significant level. The results imply that NBA players do exist the Contract Cycle Effect phenomenon that players will perform better efficiency in order to get a better contract. The Vuong test results reveal that the official NBA efficiency score has a higher association with salary comparing with DEA efficiency score. The finding suggests that the official efficiency score is one of the major references for the NBA teams on salary arbitration.

瑞特氏症(Rett syndrome, RTT)為第二型甲基化CPG結合蛋白(2methyl-CpG binding protein 2, MeCP2)基因發生突變所造成的神經發育疾病，其症狀包含了嚴重的運動障礙及自閉傾向等特徵。由於紋狀體(striatum)為運動控制的重要腦區，我們假設RTT的運動障礙主要為紋狀體的功能異常所造成，故利用RTT模式小鼠來研究紋狀體是否為RTT運動障礙的致病原因。利用敞箱試驗(open field test)及加速滾輪測試(accelerating rotarod task)結果發現，Mecp2基因剔除小鼠的活動力明顯下降，並伴隨有運動協調能力的缺失。以免疫組織染色法及西方點墨法分別標定紋狀體中的mu-opioid receptor及calbindin蛋白，發現二者表現量均有明顯下降，然而表現parvalbumin的中間神經元細胞數目卻大量增加。我們發現在紋狀體中多巴胺D2受體的表現量顯著增加，但多巴胺合成酶tyrosine hydroxylase與多巴胺訊號傳遞下游分子DARPP-32蛋白並沒有明顯減少。為了更進一步確認紋狀體的致病角色，我們利用特定在紋狀體中缺少MeCP2的「Mecp2條件缺失小鼠」，觀察其運動行為的改變。結果發現，Mecp2條件缺失小鼠不管是在活動力或是運動學習上都表現出和Mecp2基因剔除小鼠相似的運動障礙，顯示紋狀體所調控的正常活動力及運動學習能力皆需要MeCP2的參與。我們接著進一步探討是否擁有完整MeCP2表現的紋狀體就足以執行正常的運動功能。當Mecp2基因剔除小鼠的紋狀體重新表現MeCP2(即「Mecp2條件回復小鼠」)，MeCP2缺失所造成的運動障礙可被回復到接近野生型小鼠運動能力的正常水準。顯示紋狀體中MeCP2的存在為正常運動控制的充要條件。在以cyclin-dependent kinase-like 5 (Cdkl5)突變小鼠研究MeCP2的磷酸化是否會影響到運動行為，發現Cdkl5突變小鼠在出生早期及成年時期皆存在與Mecp2基因剔除小鼠一致的運動協調能力缺失。免疫組織染色及西方點墨法結果顯示，Cdkl5突變小鼠的紋狀體中mu-opioid receptor表現量有明顯下降，但parvalbumin的中間神經元數目並無改變，而在大腦皮質中多巴胺轉運子DAT1蛋白表現量明顯上升。CDKL5突變造成與RTT相似症狀的原因還須更進一步的探討。綜上所述，本研究為「紋狀體異常可能為RTT運動障礙的主要致病原因」提供動物模式的實驗證據，並提供了一個新的觀點用於未來治療RTT或防止其症狀的惡化。

本研究主要目的有三：（一）探討國小六年級學生在學習「地球的運動」前所具有的另類概念類型，及與空間能力的關係；（二）探討「地球的運動」單元各主要概念是否有發展的先後順序，及「地球形狀概念與重力概念發展」模式的適當性；（三）設計整合的概念改變教學策略，探討高、低空間能力者在不同教學層次與學習方式上的概念改變立即學習效果如何。進一步探討學習效果的持續性如何。並討論影響學生概念改變的可能因素，期能提供教學者及後續研究者之參考。 為完成前述研究目的，本研究進行研究一與研究二兩個研究，所使用的研究工具包括：地球的運動開放式紙筆測驗、地球的運動封閉式紙筆測驗、空間能力測驗、深層處理學生手冊和教學活動設計、淺層處理教學活動設計等，除空間能力測驗外，皆進行預試及修正。在研究一裡，採用問卷調查法及晤談法，以地球的運動開放式紙筆測驗，選取台北市萬興和萬福國小共235名學生為對象，考驗主要概念的發展順序。並依照空間能力測驗的結果找出前後各33﹪的學生列為高低空間能力者，考驗其在科學概念上是否有所差異。本研究一的主要結論如下： 1.高空間能力者在地球形狀、重力概念、晝夜成因、四季成因的科學概念，皆優於低空間能力者。 2.「地球形狀與重力概念的發展模式」是適當的，且各主要概念間有發展的順序存在，而學生的概念是「自然－文化－發展成熟度」三者的函數。 在研究二裡，採用準實驗研究法，首先設計「地球的運動」概念改變教學策略課程，並選取台北市萬興國小及萬福國小六年級各四個班級，共128位學生為對象，進行兩週的教學實驗，隨後進行紙筆測驗立即後測，間隔四週後進行延宕後測。根據研究所獲得資料進行分析，結論如下： 1.本研究之整合概念改變教學策略，有助於學生地球的運動相關概念的改變的立即效果和延宕效果。 2.接受深層處理的概念改變立即效果和延宕效果，皆優於接受淺層處理學習的效果。 3.配對合作學習效果會因為教學層次不同而有所不同，接受深層處理來學習時，配對合作的概念改變立即效果和延宕效果會優於個別學習。但當學生接受淺層處理時，配對合作學習與個別學習的概念改變立即效果和延宕效果並無差異。 4.配對合作學習效果會因為空間能力不同而有所不同，低空間能力學生，配對合作的概念改變立即效果和延宕效果會優於個別學習。但高空間能力學生，配對合作學習與個別學習的概念改變立即效果和延宕效果並無差異。 根據研究結果，本研究提出建議，以提供教育行政單位、國小自然科教師、課程設計者以及未來相關研究之參考。 / The purposes of this dissertation were: (1) to probe into the alternative conceptions of the students about earth's motion, and the relationship between these conceptions and spatial ability; (2) to identify the developmental sequence and model of the main concepts, and verify the model is adequate; (3) to design the instructional strategy of conceptual change and explore the learning effects that high- and low-spatial ability in different processing levels and learning styles. At last, the researcher identified the retention effect, and analyzed the factors that may influence on the conceptual change. For these purposes, the whole study was divided into study Ⅰ and Ⅱ. The instruments employed in this study included: The open-ended question test and the multiple-choice test of earth's motion, the spatial ability test, the curricula and student's manual for conceptual change teaching strategy. Except the spatial ability test, the item analysis and pilot study of the others were conducted to determine the reliability and validity, and promote the quality of this study. The study Ⅰ employed questionnaire survey and interview based on the open-ended question test of earth's motion. The participants were 235 sixth grade students from two elementary schools in Taipei. Through the data, the researcher investigated the developmental sequence of children's conceptual knowledge about the earth's motion. All students were classified as being of high- or low-ability group according to their performance on the spatial ability test. High- and Low-ability students scored upper and lower 33﹪ score of all students separately. Then the researcher examined the difference between high- and low-ability group on the performance of the open-ended question test. The main conclusions of study Ⅰ were as follows: 1. A t-test on the pretest indicated significant discrepancy for ability. In all concepts that included earth's shape, gravity concept, the causes of day/night and seasons, high- ability students outscored low-ability students. 2.The developmental model of earth's shape and gravity concept was adequate. There were developmental sequences among the main concepts. Student's conceptions are the function of physico-cultural and their developmental maturity. The study Ⅱ employed quasi-experimental design. At first, the researcher designed the teaching curricula of conceptual change. Then the researcher experimented on 8 classes of 128 students from two elementary schools in Taipei. Four intact classes were randomly assigned to different experimental groups in each school. Four groups were administered the pretest two weeks before the experimental treatment. After two weeks' instruction, all subjects accepted the posttest and delayed-test of earth's motion after 4 weeks. The results were as follows: 1.The instructional strategy of conceptual change that the researcher integrated had immediate and delayed effects. 2.Students learning by deep processing performed significantly better than the learning by superficial processing on the posttest and delayed-test. 3.The learning effect of cooperative dyads depended on the levels of processing. Students learning by deep processing environment, cooperative learning group did perform better than individual learning group on the posttest and delayed-test. Conversely, the result indicated no significant difference on the posttest and delayed-test between cooperative and individual learning. 4.The learning effect of cooperative dyads depended on the levels of spatial ability. Low-ability students with cooperative learning did perform better than those with individual learning on posttest and delayed-test. The performance of high-ability students showed no significant difference on posttest and delayed-test. Based on the results, these suggestions are proposed for educational administration institution, elementary teachers for science education, curricula designer, and future researchers.
