大專校院招生名額總量管制預期效益與指標建構之研究 / Study on Constructing Expected effectiveness and Indicators of the Enrollment's Total Amount Control of Higher Education

莊清寶, Chuang, Ching-Pao Unknown Date (has links)
我國自83學年度推動教育改革以來,至94學年度為止,學士班人數已由30萬2,093人增加為93萬8,648人、碩士班人數由3萬832人增加為14萬9,493人、博士班人數則由8,395人增加為2萬7,531人,可見近年來大專校院學生數可謂急遽地增加。而我們由94學年度大學考試分發入學錄取率高達89.08%,更顯示進入大學就讀已絕非難事。然而鑒於我國2005年的出生人口數已從2000年的30萬5,312人降至20萬5,854人,在此少子化的趨勢形成影響前,93學年度大專校院的缺額數卻已高達6萬471人,顯現出大專校院的招生呈現出明顯供過於求的現象。研究者於是對中央主管教育行政機關以「總量管制」方式核定大專校院招生名額的機制產生濃厚研究興趣。   本研究採用「文獻分析法」及「問卷調查法」等兩個研究方法進行研究,其中旨在探討此大專校院招生名額總量管制之政策沿革與現況,並以更多元、開放的角度探討大專校院招生名額總量管制應達到哪些預期效益且嘗試建構其因素模式,接著依據前述預期效益建構出適當的大專校院招生名額總量管制指標,最後則探討不同背景變項(如性別、年齡、最高學歷、身份、學校體系、學校性質等)的受試者對大專校院招生名額總量管制預期效益與指標看法之差異。   本研究以李克特六點式量表、網路問卷形式設計成「大專校院招生名額總量管制預期效益與其指標調查問卷」來作為研究工具,並以「兩階段取樣」的方式來廣泛蒐集大專校院教師、職員與學生等研究對象的同意程度看法。其中第一階段係分別藉由函請各校轉寄E-mail通知該校教職員及學生上網填答、至各校bbs發表文章進行問卷施測通知等兩種途徑,獲得回收樣本數8,473份,扣除無效問卷317份後,總計有效回收問卷為8,156份,並據以建置為樣本資料庫。第二階段則採分層隨機抽樣方式分別於大專校院教師、職員及學生等三層各抽出336個樣本,總計獲得1,008個樣本。 此1,008個樣本將分別以SPSS 13.0及LISERL8.72等兩套統計軟體進行資料分析,其中將採用次數分配與百分比、算術平均數與標準差、t檢定、獨立樣本單因子變異數分析、驗證性因素分析等統計方法進行分析,並經專家效度、聚合效度、區別效度及交叉驗證效度、Cronbach’s α係數、潛在變項的組合信度、個別觀察變項的信度等檢定過程中證實本研究具有良好的研究效度與信度。   本研究總計建構出13個大專校院招生名額總量管制預期效益,其同意程度平均數(M)介於4.48∼5.28之間,同意百分比(P)則介於81.5%∼96.4%之間;至於此預期效益之因素模式則也獲得相當良好的適配結果,並據以證實大專校院教師、職員與學生對於大專校院招生名額總量管制預期效益的同意程度看法,會受到「保障大專校院教學品質」、「符合學生性向與需求」「符合就業市場人力與專業需求」、「大專校院競爭力之維持與提昇」等4個潛在因素構面(或稱構念)的影響。接著,並依據前述預期效益建構出26個大專校院招生名額總量管制指標,其同意程度平均數(M)介於4.30∼4.94之間,同意百分比(P)則介於79.0%∼93.9%之間。 此外,本研究亦發現,在性別、年齡、最高學歷、身分、專兼職情形、學校體系與學校性質等7個不同背景變項的受試者對大專校院招生名額總量管制預期效益與指標之同意程度看法的差異中,除了不同「學校體系」變項的受試者對指標看法沒有顯著差異、但對預期效益看法有顯著差異外,其餘6個不同背景變項皆在預期效益與指標的看法上有顯著差異。 最後,本研究並依據研究成果,提出下列具體建議: 一、總量管制預期效益不宜只考量「維持教學品質」,應進一步關注學生   需求、就業市場需求、以及學校競爭力等方面的預期效益之達成情   形。 二、總量管制指標不宜只考量到生師比、師資結構與校舍面積等指標,應  以多元觀點發展出更多指標,以充分掌握招生管理資訊。 三、總量管制不應侷限在「每年成長總量的管控」,而應納入「減少招生  名額」的情境條件。 四、宜適度減少各校擴增招生名額的誘因。 五、宜研議總量管制業務整併之可行性。 六、總量管制資料的蒐集宜化被動為主動,以掌握客觀審查資訊。 / When Taiwan setting into education reforms from 1994 school years till 2005 school years, the students at classes of bachelor degree increase to 938,648 from 302,093, the students at classes of master's degree increase to 149,493 from 30,832, the students at classes of doctor's degree increase to 27,531 from 8,395. It is perceived that students of higher education increasing rapidly. Furthermore, the admission rates of universities' enrollment paths by entrance examination grades reaches 89.08%, it appears that entering into universities is not hard anymore. However, since population of births had reduced to 205,854 at the year of 2005 from 305,312 at the year of 2000, and before the impact of trends of few-children, the vacancies of enrollment of higher education had reached 60,471, we can find a obvious phenomenon that the supply of enrollment of higher education exceeds the demand. So I have a strong interest in the mechanism of how Ministry of Education ratifying the enrollment of higher education by the method of "Total Amount Control".   The study adopts two approaches, that is "literature review" and "questionnaire survey", and it explores the policy's developing progress and current situation of the enrollment's total amount control of higher education. Furthermore, it explores what expected effectiveness of the enrollment's total amount control of higher education should be reached with the diverse and liberal viewpoints, and tries to construct its factor model. Then according to the expected effectiveness, we establishes appropriate indicators of the enrollment's total amount control of higher education. Finally, we explore if subjects with different background variables, such as sex, age, degree, identity, full/part time, system of school, character of school, will have significant differences about opinions of expected effectiveness and indicators of the enrollment's total amount control of higher education.   The study designs the "questionnaire of expected effectiveness and indicators of the enrollment's total amount control of higher education" with Likert six point scale and network questionnaire, and broadly collects samples of teachers, officers, and students of higher education by the methods of "Two stage Sampling". At the first stage, I use two survey ways, that is e-mail informing and bbs informing, and I get 8,473 returned samples, and finally get 8,156 valid samples after reducing 317 invalid samples. At the second stage, I gains 1,008 samples from three layers of teachers, officers, and students of higher education with "stratified random sampling".   The 1,008 samples will be analysed by two software of SPSS 13.0 and LISERL8.72. The ways of analysis include frequency and percentage, average and standard deviation, t-test, one-way ANOVA, confirmatory factor analysis. Furthermore, after the examining of expert validity, convergent validity, discriminant validity, cross- validity, Cronbach's α, composite reliability, and individual observed variables' reliability, we have confirmed the study has good study validity and reliability. The study finally constructs 13 expected effectiveness of the enrollment's total amount control of higher education, and its average of agree extent between 4.48 to 5.28, its agree percentage between 81.5% to 96.4%. Furthermore, the factor model of that expected effectiveness has good fit results too, it confirms that the opinions on expected effectiveness of the enrollment's total amount control of higher education will be influenced by the latent factors of "Ensure the teaching quality of higher education", "Matching with students' aptitude and needs", "Matching with manpower and specialty's needs of job market", "keep and promote the competitive ability of higher education". Then according to the expected effectiveness, we establishes 26 indicators of the enrollment's total amount control of higher education, and its average of agree extent between 4.30 to 4.94, its agree percentage between 79.0% to 93.9%.   Furthermore, the study find among the opinions' difference of agree extent on expected effectiveness and indicators of the enrollment's total amount control of higher education from 7 different background variables, such as sex, age, degree, identity, full/part time, system of school, character of school, beside the "system of school" haven't significant difference on indicators but have on expected effectiveness, other 6 different background variables all have significant difference on expected effectiveness and indicators.   Finally, according to the results of this study, I propose some suggestions as follow: 1.The expected effectiveness of total amount control shouldn't be restricted within "maintain teaching quality", we should consider the expected effectiveness' implement of students' need, job market's need, and school's competitiveness further. 2.The indicators of total amount control shouldn't be  restricted within the indicators of student-teacher rates,  structure of teacher, superficial contents of school  buildings only, we need more indicators with diversified  viewpoints to get information for enrollment's managing. 3.The total amount control shouldn't be restricted by "the  amount control of every years' growth", we need to add the  conditions of "reducing enrollment". 4.We should try to appropriately reduce the "inducing factors"  of universities increasing enrollment. 5.Ministry of Education should try to merge the affairs of  total amount control from different departments. 6.We should collect the data of total amount control actively  instead of passive, so that we can get objective information  to examine.

劉育如 Unknown Date (has links)
本研究的主要目的是以美國全人醫治協會(American Holistic Medical Association,AHMA),提出的全人醫治取向(AHMA, 2005),發展出一份新取向的憂鬱量表,同時探討憂鬱症的相關因素。針對憂鬱症而言,全人的醫治方式需要檢視情緒、人際關係、身體和心靈等各個層面。因此,本研究所發展的自編憂鬱量表依全人醫治取向將其為分為認知取向、情緒取向、身體取向與人際取向等四個因素。 本研究量表的計分方式採用李克特式四點量表形式。原始量表共37題,依據文獻與醫院觀察所得資料編製而成。原始量表以專家效度作為刪題依據,刪題後的正式量表為22題。其計分方式,答「總是如此」得3分,「經常如此」2分,「偶爾如此」1分,「很少如此或沒有」0分。樣本分為實驗組(憂鬱症者)與效標組(非憂鬱症者),實驗組是以精神科醫師診斷為憂鬱症者共213人作為量表的填答對象,效標組是隨機抽取政大學生200人作為施測樣本,並以CES-D憂鬱量表作為效標。施測所得資料以SPSS進行描述統計、t考驗、效標關聯效度、分量表與總分之相關、區別分析、內部一致性信度的考驗;並以結構方程式模式(SEM)針對驗證性因素分析、多群組共變數結構與多群組潛在平均數結構進行考驗。 本研究的結論下: 一、本研究結果,憂鬱症好發年齡與國外25-44歲研究相符,與國內20-40歲研究結果相同。依據文獻所示,女性罹患憂鬱症的比例,為男性的2倍,本研究結果顯示與國內外研究結果是一致性。 二、各分量表與總分之間的相關從.836到.903皆為非常良好的係數值,表示本研究自編憂鬱量表具有良好的內部一致性。 三、本研究之效標關聯效度達0.939,雙尾檢定,達.01顯著水準,表示本研究所編製的量表,可測得所欲測得的特質。 四、本研究的自編量表整體內部一致性Cronbach's Alpha係數為.965,其他如刪除各單題後的總量表、校正後單題與總量表之相關、校正後單題與分量表之相關都顯示本研究自編憂鬱量表有良好的信度。 五、驗證性因素分析模式是合理適配的,表示當初四個向度假設是成立,而且這四個因素背後有一個潛在因素-「憂鬱症」存在。 六、實驗組與效標組在共變數結構上的考驗是沒有差異的,表示此自編憂鬱量表可以同時適用在實驗組與效標組。 七、分量表或總量表從t考驗值差異皆達.001顯著水準,另外區別分析Hit Ratio值為0.93,表示本研究自編之憂鬱量表具有良好之區別效度,可以有效地區別出實驗組與效標組。而在多群組潛在平均數結構上的考驗,效標組在自編憂鬱量表四個向度上的潛在平均數低於實驗組,表示本量表從潛在變項的考驗也可以有效地區辨實驗組與效標組。 / The main purpose of this study is to develop a depression scale in a new approach that reflects the whole-person approach to healing proposed by the AHMA (the American Holistic Medical Association) in the United States (AHMA, 2005), while at the same time probing into the relevant factors of depression disorders. Regarding depression disorders, a whole-person approach to healing requires the examination of multiple dimensions of the person, such as mood, interpersonal relationships, body, soul, etc. So, this study of the development of a self-establishment depression scale is divided into four dimensions: cognitive, mood, physical, and interpersonal, in accordance with the whole-person approach. The scale of this study adopts a four-item Likter scale to measure scores. The basic scale amounts to 37 items and works out according to the literature and the observing materials in hospitals. Items of the basic scale are deleted with expert validity. It is a 22- items formal scale after deleting items. Answer choices read and rate as follows: “always true” (3), “often true” (2), “true once in a while” (1), “seldom or not true” (0). Samples are separated into the experimental group (depressed person) and the criterion group (non-depressed person). In the experimental group, psychiatrists diagnosed 213 people for depressed person as the measuring target filling of the self-establishment depression scale. The criterion group consisted of 200 National Chengchi University students. CES-D was used as a criterion t. We used the program of SPSS to compute descriptive statistics, t-test, criterion-related validity, correlation of the sub-scales and the scale, discriminant, reliability of internal consistency with SPSS, and the estimations of confirmatory factory analysis, multi-sample covariance structure, multi-sample-latent-means structure with structural equation modeling (SEM). In sum, some conclusions of this research are as follows: 1. The result of this study show that depression disorder peaks during the ages of twenty-five to forty-four, consistent with in foreign and domestic research. As literature, depression disorder occurs in at double the rate in women as in men, and the result of this study is consistent with domestic and foreign studies. 2. The correlative coefficient of the sub-scales and the scale from .836 to.903 shows all as having very good coefficient value and that it has good internal consistency of the self-establishment depression scale. 3. The criterion-related validity of this research is up to 0.939, 2-tailed test reaches .01 level of significance which shows the self-establishment depression scale can examine the attributes which we want to find out. 4. The whole internal consistency Cronbach's Alpha coefficient of the self-establishment depression scale is .965, others like Cronbach's Alpha if item deleted, corrected item-total correlations single item with sub-scales and corrected item-total correlations single item with the scale all show good reliability. 5.The model confirmatory factory analysis is reasonably fit that shows four dimensions established supposing originally, and behind the back of four factors there is one latent variable – “depressive disorder” exists. 6.The estimation of covariance structure between the experimental group and the criterion group shows no difference that reveals the self-establishment depression scale can be suitable for the experimental group and the criterion group . 7.The sub-scale and the scale of the self-establishment depression scale from t-test reaches .01 level of significance, another time hit ratio value of discriminant is 0.93, both show that the self-establishment depression scale by this study can distinguish the experimental group and the criterion group efficiently. And at the estimation of multi-sample-latent-means structure shows the criterion group’s latent mean is lower than the experimental group’s, that means this scale can distinguish the experimental group and the criterion group usefully at the same time.

精品品牌奢侈量表建構之研究 / Constructing the Brand Luxury Scale

楊淳聿, Yang,Chun-Yu Unknown Date (has links)
「奢侈平民化」帶動奢侈品牌年年高成長的業績,卻迫使品牌必須面對截然不同的消費者態度與品味。品牌欲持續保有強勢地位,必須了解奢侈在消費者心目中的意義以及消費者如何評估奢侈品牌。因此,本研究欲探討台灣精品消費者認知中構成品牌奢侈的因素,建構衡量品牌奢侈之量表,並以量表探討消費者購買經驗對奢侈認知之影響,及分析個別品牌的現況及優劣勢,研擬具體的競爭策略方向。 本研究選取五個奢侈品牌作為分析標的,進行實證研究,期望達到下列研究目的: (1)驗證品牌奢侈量表,建立評估奢侈品牌的管理工具; (2)探討不同奢侈品牌購買經驗之消費者對各品牌奢侈認知的差異性; (3)探討各奢侈品牌在消費者心目中的知覺定位,擬定未來的策略方向。 依本研究之目的,擬定研究架構及確立抽樣設計,並發放問卷收集消費者資訊。之後以二階驗證性因素分析檢驗品牌奢侈量表模式品質;再利用量表探討不同購買經驗對奢侈認知的影響;最後則以多元尺度分析進行知覺定位分析,經實證分析得到以下研究發現: (1)品牌奢侈包含知覺炫耀性、知覺獨特性、知覺品質、知覺享樂價值與知覺延伸自我等五個構面,其影響力依序排列為知覺享樂價值>知覺延伸自我>知覺獨特性>知覺炫耀性>知覺品質。 (2)台灣地區消費者於購買奢侈品牌之產品後,對品牌奢侈程度的認知無明顯地降低,對品牌的奢侈評價與無購買經驗者沒有顯著差異。 (3)各奢侈品牌的改善重點主要包括知覺品質、知覺享樂價值以及知覺獨特性等三項,其中知覺品質為市場最重要之關鍵因素。 根據實證分析之結果,衍生出許多的策略涵意,包括掌握關鍵因素、規劃競爭策略以及未來發展方向等,可以作為奢侈品牌改善或塑造奢侈形象及規劃策略方向的參考依據。 / “Luxury Democratization” brings great growth to the luxury goods market, but also forced these brands to confront consumers with different attitudes and tastes. As a result, it is critical for luxury brand managers to understand consumer’s perception of brand luxury in order to maintain the brands’ luxury image. This research focused on the confirmation of Brand Luxury Scale to understand Taiwanese cousumers’ perception of brand luxury. Based on the Scale, the influence of purchase experience to luxury perception was tested, and the competitive advantages of five luxury brands were analyzed. Competitive strategies of each brand were futher developed. Research was conducted by using five luxury brands and expected to achieve the following research purposes: (1)Confirm the Brand Luxury Scale to establish a managerial tool for brand luxuriousness evaluation; (2)Use the Brand Luxury Scale to evaluate the influence of purchase experience to luxury perception; (3)Use the Brand Luxury Scale to evaluate consumers’ perception of different brands, and seek to imply different competitive strategies for these brands base on the analysis. After the conduction of research framework, sampling design and data collection, Secondary Comfirmatory Factor Analysis was used to confirm the structure of Brand Luxury Scale. 1-Way ANOVA was used to test the influence of purchase experience to luxury perception. Finally, Multi-Dimensional Scaling Analysis was implied to analyze the perceptual position of each brand. The research findings are as below: (1)Brand Luxury is constructed by five dimensions: Perceived Conspicuousness, Perceived Uniqueness, Perceived Quality, Perceived Hedonic, and Perceived Extended-self. The order of dimensional influence is Perceived Hedonic> Perceived Extended -self> Perceived Uniqueness> Perceived Conspicuousness> Perceived Quality. (2)No difference in brand luxury perception between different purchasing experience consumers was found, showing that the perceptions of brand luxury of Taiwanese consumers’ remain unchanged after purchase. (3)Perceived Quality is the most important dimension of all, and the five luxury brands tested needs to improve in dimensions of Perceived Quality, Perceived Hedonic, and Perceived Uniqueness. According to the results, several managerial implications were derived, including key factors in marketing and competitive strategy of each brand. These strategies can be used in improving the performance of perceived luxuriousness of brand, enhancing brand luxury image, and planning the direction of luxury marketing and brand strategy.
