近年來，社會經濟進步，對「不動產估價」之需求日益殷切，例如投資房地產、利用房地產來進行借貸行為等各項需要，在在皆得依靠不動產估價的技術，因此提升了社會上對不動產估價的重視。而在今日科技如此蓬勃發展的資訊時代，若能將不動產估價的技術與電腦的數位技術相互結合，藉由電腦的強大計算能力與快速的回應能力，相信必能提升不動產估價的技術及準確度。 　所以本研究致力於將不動產估價與電腦科技相結合，期望能提升不動產估價的準確度，除了利用其強大的計算能力之外，本研究更進一步地將不動產估價動作與地理資訊系統ＧＩＳ（Geographic Information System）相結合，利用ＧＩＳ強大的地理資料處理能力，希望能將不動產估價的技術提昇至更高的境界。 　本研究的研究過程為先對不動產估價之理論與方法進行研究，並尋找出不動產估價時的程序及其所需要考量的事項，在整理融會之後，再進一步地結合ＧＩＳ，以建構出一個以ＧＩＳ為基礎的不動產估價系統。且每當一估價個案完成，系統便自動將此筆估價個案之資料與結果回饋（輸入）給系統，成為一筆新增之買賣實例，如此一來，買賣實例資料庫將會愈來愈大，愈來愈完整，也將會使得系統的估價能力愈準確、可信度愈高。 因為在台灣不動產估價已經逐漸受到社會各界，例如銀行、租賃公司和房屋仲介公司等的重視，所以本研究企圖整理出各種常用估價模式及其所需的資料，並結合地理資訊系統（Geographic Information System，GIS）的技術，建構出一個以ＧＩＳ為基礎的泛用型不動產估價資訊系統之原型，期能藉此提高不動產估價行為的效率與精確度，並希望對ＧＩＳ的應用領域提供一個新的窗口，進而擴大ＧＩＳ的長遠發展。 / Recently, the need for appraisal of real estate is more and more important for people. When we invest the money in the real estate or use real estate to borrow money, we must depend on the technique for appraisal of real estate. Now, we are in the information world. If we can take advantage of the ability of the computer to appraise the real estate, it must be able to promote the technique and accuracy of appraisal in real estate. 　So in this thesis, it was applied to combine the appraisal in real estate and the ability of the computer and it hoped that it could increase the accuracy of appraisal. Besides the computing ability, this thesis wanted to combine the technique GIS (Geographic Information System) and the appraisal in the real estate. It wanted to take advantage of the processing ability in geographic data in GIS to higher the technique in appraising real restate. 　In this thesis, we attempt to arrange some general appraisal models and data the models need and to use the technique of GIS to design a prototype appraisal system. We hope that the system will be able to higher the efficiency and accuracy of appraisal in real estate. And we hope we will create a new way to take advantage of the ability of GIS.

不動產估價一般需採比較法、收益法及成本法等三種方法查估。不動產估價最終估值決定須進行協調(reconciliation)，協調的目的係為完成關聯(correlation)之步驟，就各種方法資料之質量及優缺點進行分析。為使不動產估價對於比較法三件買賣實例，及三種方法估值採賦予權重之決定方式提供量化解釋，本文分別建立比較法內部及三種方法外部權重模型。內部權重部分，買賣實例（市場）比較法一般需蒐集數個比較標的，經調整後之試算價格決定比較價格。國外以數學計算式計算實例權重雖已相當普遍，但目前尚無應用特徵效用模式，解讀實例權重形成與比較標的內部條件之關聯。本文以2007年及2008年地價基準地6,435筆買賣實例建構特徵權重模型，發現比較法買賣實例權重受價格型態、交易日期接近性、是否屬近鄰地區、實例差異百分率絕對值加總、實例比較項目修正數、其他兩個實例相對值等自變數影響顯著。 欲探討成本法估值是否與成交價存在差異，以作為外部權重設定之基礎，本文以北部地區986筆交易案例，由估價人員逐筆以成本法估計成本價格，俾與成交價格比較。發現成本價格有高估之系統性偏誤現象，分量迴歸(quantile regression)分析實證認為成本法並未因屋齡較新之建物有較高精度。另發現房地交易價格愈高、建物單價愈高、總樓層數愈高、移轉樓層愈低、建物面積愈小、建築工期愈長及利潤率愈小者；估值差異愈小。 外部權重分為三部分，首先將估價過程中之諸項因子，以分析階層程序法(AHP)專家問卷，彙整各種方法權重因子；其次，基於最適加權平均模式在於使三種方法估值總誤差最小之觀點，經由數學計算方程式建構2,150筆基準地三種方法標準差及相關係數模型以計算權重。第三、為了瞭解比較估值、收益估值與土地開發分析估值之關聯，本文將2,150筆三種估價方式權重建立聯立模型，以三階段最小平方法(3SLS)進行估計。實證模型系統加權解釋力甚高，且三種方式權重之自變數多符合預期並顯著，顯見三種方式之關聯性。 最後，不動產估價仍需考慮一般因素，如金融海嘯對全球金融及房地產市場，其影響力無遠弗屆，最終估值之決定即需考慮市場景氣對最終估值之影響。為探討對於(不)景氣時是否(低)高估？影響(低)高估與否之影響因素為何？本文以2002年至2004年國內某金融機構對房屋貸款20,532件之估值，以二項式邏輯特(Binary Logit)模型分析。實證結果發現於不景氣時期抵押貸款低估機率提高，景氣時期則無高估現象。綜上，本文以權重模式、估值差異及市場景氣影響探討不動產估價最終估值之形成，於權重模型建構及預測上，非如以往文獻僅對估值預測，而係就權重預測。於加權平均應用上，外生變數之迴歸係數可作為權重設定之參考。本文直接探討最終估值形成之權重核心，冀使估價之客觀性及科學化程度提高。 / Real estate appraisal comprises the sales comparison, income, and cost approaches to value in general. The purpose of reconciliation is to complete the procedure of correlation and analyze the qualitative and quantitative strengths and weaknesses of different approach data. In order to assist quantifiable explanation when weighted average for three comparables in the Sales comparison approach and indicated values from three approaches are applied, this paper constructs internal and external weight models respectively. For internal weight model, this paper examines the correlation between weight and internal attributes of 6,345 sales comparables from land value benchmark in 2007 and 2008 adopting the hedonic price model. The outcome shows the price type, the proximity of transaction date, inside the neighborhood area or not, total gross adjustment as %, numbers of adjustments and the attributes of other two comparables considered in one appraisal are significant on the weight of comparables. To explore whether the cost approach causes bias or not, and make it reference for establishment of external weight model, this paper compares the cost value, appraised by valuers applying the cost approach individually, from a sample of 986 transactions of properties sold in 2007 and 2008 in northern Taiwan, to sale price and finds the cost value is higher than sale price on average. It proves that the reliability of the cost approach is comparatively questionable due to its systematic bias of overestimation. With quantile regression, the outcome shows that the precision of cost value won’t increase for newer buildings. In addition, this paper finds the more the total property sales amount, the higher the unit construction fee, the higher building, the lower story, the smaller area, the longer construction years of properties, and the smaller profit rate; the smaller the bias. There are three parts for external weights. First, AHP expert questionare is adopted to combine weight factor from each approach. Secondly, based on the logic that the best way to assign weights on three appraisal approaches is to get the minimum total error, this paper calculates the standard error and correlation indicators from three approaches using 2,150 land value benchmarks. Thirdly, in order to realize the weights correlation among the sales comparison value, income capitalization value and land development analysis value, this paper builds a model based on the three-stage least squares method simultaneous equation (3SLS). The empirical result shows system weighted R2 is high and most attributes on the weights of three indication of value are significant and are consistent with expected sign, which means the model fit is good and how the weights of three methods correlate. Finally, general factor also needs to be considered in real estate appraisal. For instance, financial tsunami exerts powerful influence on financial and real estate market globally, which makes it necessary to consider real estate cylce influence when seeking the final value. In order to discuss whether the appraisal value of mortgage is smaller (greater) or not when the market is bearish (bullish) and the corresponding factors, this paper collects 20,532 mortgage appraisal value from one bank from 2002 to 2004. With Binary Logit model, this paper finds the probability of lower appraisal is greater in bear market. The outcome confirms two hypotheses of this paper. However, overestimation is not confirmed in bull market. To sum up, this thesis researches the formation of final value of real estate appraisal by discussing weight model, appraisal bias and influence of real estate cycle. For weight model construction and forecasting, this dissertation forecasts weight directly, instead of value like most literature focus. The regression coefficients estimated from factors during the procedure of each approach could serve for reference if weighted average is applied reconciling the value conclusion by valuers. By delving into the core issue of value formation, it hopes to elevate the degree the objectivity and science of real estate appraisal.

The effective management of individual/team performance is a crucial requirement to ensure that organisational goals are attained. This requires accurate data regarding the performance levels of individuals/teams. Therefore there is a need for a standardised and formal performance management system. An effective performance management system is the centre of an integrated HR system that feeds into a variety of processes and systems such as career planning, rewards, training and development, promotions, and disciplinary decisions. Despite the importance of performance management, most organisations find it difficult to implement, manage and sustain performance management systems and processes effectively. The focus of this study is on appraising the performance management practices in the offices of the Department of Labour in three provinces: Gauteng, Limpopo and Mpumalanga. The results indicate problems with the practices in areas such as alignment, fairness, measuring commitment, systems integrity, and the performance management culture. Recommendations were made to address these issues and improve the effectiveness of the system / Human Resource Management / M. Tech. (Human Resource Development)

特徵價格模型是傳統常被使用於不動產大量估價的模型，由於模型將造成所有價位的不動產其特徵都具有同樣的邊際價格而無法解釋現實不動產特徵的各種可能狀況，故引發本研究利用分量迴歸建立大量估價模型之動機。研究利用台灣不動產成交行情公報的資料進行台北市大廈的實證分析，針對特徵價格法的延伸與估價準確度做檢視。嘗試應用分量迴歸建立大量估價模型，討論住宅特徵對於價格的邊際影響力於不同價位的住宅是否存在差異，並討論分量迴歸模型的估價精確度。研究採用交互驗證法與重複實驗30次討論模型的估計效果，並利用平均絕對百分比誤差（MAPE）以及命中率（Hit Rate）做為模型預測優劣程度的衡量標準，以討論分量迴歸模型是否可以較最小平方特徵價格模型有更為準確的估計表現。實證首先探討價格分量之下各住宅屬性對於價格的影響狀況，得到大部分住宅特徵對於價格的邊際影響力的確會因住宅價位的不同而有所差異。在估價準確度的部份，經測試得到利用分量迴歸建立大量估價模型的估價效果達研究的預期目標，且其估計表現優於最小平方特徵價格模型。 / 藉由分量迴歸模型，得到隨著住宅價位的增加，坪數與屋齡對於價格的影響力並非呈現一致的趨勢；坪數輪廓與屋齡輪廓出現轉折也為變數增加二次項變數的原因得到實證依據。重複實驗30次的整體表現，分量迴歸模型的MAPE較最小平方迴歸模型低了1.687％；誤差落在正負10％的Hit Rate較最小平方迴歸模型高了3.81％；誤差落在正負20％的Hit Rate較最小平方迴歸模型高了5.14％。30次的實證為分量迴歸模型的估價表現更優於最小平方迴歸模型得到較具說服力的結果。 / Hedonic pricing models are traditionally used for real estate automated valuation models. Because the conditional mean calculated by OLS does not give a complete description of the relationship between dependent variable and independent variables, which leads to the motive of this study. This study inspects the extension of hedonic pricing models and appraisal accuracy, and we attempt to apply quantile regression to real estate automated valuation models and discuss the difference of the marginal contribution in each individual characteristic under different price level. Our study adopts cross validation and repeats empirical process for 30 times, and we use MAPE and hit rate to evaluate accuracy and argue if quantile regression models have better estimation. The empirical results show that the marginal contribution of housing area and age changes with price level; the turning points of area curve and age curve show empirical evidence for including square variables. The entirety performance of repeated experiments points out that the MAPE of quantile regression model is 1.687% lower than OLS model; as error ranged between 10% to -10%, the hit rate of quantile regression model is 3.81% higher than OLS model; as error ranged between 20% to -20%, the hit rate of quantile regression model is 5.14% higher than OLS model. The 30 times experiment of quantile regression models shows a much more persuasive result than OLS models.

The purpose of this study is to explore the manager-subordinate conflicts or disagreements in relation to performance appraisal in the Department of Home Affairs in Tshwane area. An understanding of the reasons for manager-subordinate conflicts pertaining to performance appraisal is essential in order to identify viable solutions for improving workplace relations and morale. In order to achieve the purpose of this study, a qualitative research design was adopted, whereby semi structured interviews were used to collect data. A sample of twenty five research participants was selected from five offices of the Department of Home Affairs in Tshwane area using a purposive sampling strategy. Qualitative content analysis was conducted to analyse data obtained through interviews and observations. The major findings of the study revealed that performance bonuses and biased ratings are the sources of conflicts or disagreements between managers and subordinates in relation to performance appraisals. Therefore, is recommended that the National Department of Home Affairs should expose both managers, supervisors and operational staff members to training and development to ensure an effective performance appraisal process. In addition, managers and supervisors should be equipped with necessary conflict management skills to resolve manager-subordinate conflict in the workplace. / Public Administration / M. Admin.

Este trabalho se situa na fronteira entre os estudos culturais e os estudos lingüísticos. Ele tem como objetivo observar possíveis diferenças em termos de organização de gênero e escolhas lexicais entre os anúncios pessoais feitos por gays e heterossexuais do sexo masculino. O corpus de análise consiste de quarenta anúncios retirados de dois sites de encontros da Internet, sendo que vinte são originariamente escritos por gays e os outros vinte por heterossexuais do sexo masculino. A base desta pesquisa se encontra nos trabalhos de Swales (1990) e Bhatia (1993) sobre a descrição de gêneros e no trabalho de Hoey (1997) sobre narrativas eróticas. Deste último retiramos alguns conceitos sobre a auto-descrição e a descrição do objeto de desejo. Inicialmente, os anúncios eletrônicos pessoais são comparados com anúncios pessoais impressos (cf. Shalom 1997), na tentativa de verificar como os anúncios impressos podem ter se adaptado ao meio digital. Num segundo momento, a análise se concentra na aplicação do sistema de Avaliação (ou Appraisal) de Martin e White (2005) a fim de caracterizarmos como os gays e heterossexuais do sexo masculino avaliam a si próprios e a seus objetos de desejo. A dissertação sugere que há diferenças relacionadas ao posicionamento atitudinal dos gays e heterossexuais, especialmente em relação à utilização de Afeto. Observam-se diferenças também não previstas por nossas perguntas de pesquisa, que não podem ser atribuídas nem às organizações diferentes dos sites, nem às escolhas lexicais dos anunciantes, mas sim aos tipos de sites e audiências escolhidos pelos anunciantes / The present work lies on the borderline of cultural and linguistic studies. It aims at examining whether there are differences concerning genre organization and lexical choices in ads filled in by gay and heterosexual males. The corpus consists of forty ads from two dating sites on the internet: twenty are originally written by gay males and the other twenty are written by heterosexual males. This research draws on works such as Swales (1990) and Bhatias (1993) on genre description and on Hoeys (1997) on erotic narratives. From the latter we have borrowed a few key concepts to help us analyze self and other description. At an early stage, the internet ads are compared to printed ads (cf. Shalom 1997) in an attempt to check how these ads should have adapted to the digital medium. Afterwards, we resort to Martin and Whites (2005) Appraisal system so as to characterize how gays and heterosexuals see themselves and their desired others. The dissertation suggests that there are differences related to the attitudinal positioning of gays and heterosexuals, particularly in the use of Affect. There are also findings unforeseen at the beginning of the research. In other words, these differences do not come down either to the variation in the organization of the sites, or to the lexical choices of the advertisers, but rather to the kind of site chosen by the advertisers

In the field of artificial intelligence the production of believable emotions are vital to be able to produce believable behavior of virtual agents. This is done with a process called affective appraisal, which means that events and situations are appraised and emotions are produced accordingly. The Artificial Intelligence and Computer Graphics (AICG) lab at Linköpings University has been devel- oping an AI architecture for virtual agents. This architecture had an appraisal module in need of improvement. This M.Sc. thesis had the purpose of doing this. Several approaches to affective appraisal are discussed and compared and finally one approach, called the OCC model, is chosen for implementation. This model is suitable for a real-time AI architecture as it is simple, easy to implement and can produce a wide range of emotions. The implementation of the OCC model is described in terms of how its different parts are incorporated into the previously existing AI architecture. Three extensions to the OCC model are also implemented to improve the results: emotional memories, the appraisal of unexpected events and interaction between the produced emotions. Finally the implementation is tested and the results of the tests are discussed. It is found that the implementation produces sufficient results for the scope of the thesis and for the requirements of the AI architecture into which it is incorporated.

The first part of the diploma thesis defines the terms used in relation to real estate appraisal, description of the appraised localities, and description of the individual appraisal methods. The practical part of the diploma thesis provides a description and an appraisal of six family houses situated in various urban areas with different public facilities. It regards appraisal by the cost method, comparative method according to regulations and non-regulation comparative method. The aim of the thesis is to compare the impact of accessibility of services on the marketability of family houses in urban areas with different public facilities.

In the process of reform and development in South Africa, set in motion after its first democratic elections (1994), educators have the unique opportunity to re¬think, re-plan and re-structure the music education system holistically within the context of formulating unit standards now required by the South African Qualifications Authority (SAQA) for all learning areas. This thesis addresses two aspects in this process, against the background of the broader MEUSSA (Music Education Unit Standards for Southern Africa) Research Project, namely the development of a model for music education in Southern Africa and its application in a General Music Appraisal Programme (GMAP) for all learners. The MEUSSA Model, developed in this thesis, captures and displays the key elements necessary to compile unit standards across the board in music education, as identified by the author and endorsed by the MEUSSA team. These standards are grouped together in a musically logical way under collective headings. The three-dimensional model in the form of a cube can be manipulated according to the needs of the specific music practice involved, at the same time keeping the broader context of music education in Southern Africa in perspective. The MEUSSA Model is intended by the author to keep the standards generating process together cohesively. The author implements the MEUSSA Model in the GMAP, which she compiled with the aim of providing a general music education background for all learners in Southern Africa. The learning outcomes (unit standards) address music-¬specific skills, knowledge and attitudes with their related assessment criteria. / Thesis (DMus)--University of Pretoria, 2006. / Music / unrestricted
