Die bruikbaarheid van die Goodenough draw-a-man-meetmiddel ten opsigte van verstandelik gestremdes

Saptouw, Manuel January 1993 (has links)
Magister Artium (Psychology) - MA(Psych) / Die bruikbaarheid van die Goodenough Draw-A-Manmeetmiddel met verstandelik gestremdes is ondersoek. Die Goodenough Draw-A-Man-meetmiddel, alhoewel aangewend om intelligensievlak van verstandelik gestremdes te bepaal, het beperkte ondersteuning volgens gepubliseerde studies. Twee studies het kontrasterende bevindinge ten opsigte van die bepaling van spesifieke grade van verstandelike gestremdheid aangedui. Ander studies het die geldigheid van die meetmiddel ten Die huidige studie het die volgende ondersoek: die bruikbaarheid van die Goodenough Draw-A-Man-meetmiddel ten opsigte van die klassifisering van die verskillende grade (sowel as onderverdeelde grade) van verstandelike gestremdheid; die verhouding tussen verstandelik gestremdes se prestasie op die Goodenough Draw-A-Manmeetmiddel en die volgende veranderlikes: geslag, ouderdom, institusionalisering versus nieinstitusionalisering; en om stereotiperende mensfiguurtekeninge en leerpotensiaal te ondersoek. van kronologiese ouderdom en geslagsverskille, sowel as die algemene bruikbaarheid met verstandelik gestremdes bevraagteken. Die ondersoekgroep het bestaan uit 153 verstandelik gestremdes met kronologiese ouderdomsomvang van 7 jaar tot 84 jaar. Hierdie subjekte is as erg tot verstandelik gestremd geklassifiseer. Hierdie groep het bestaan uit 64 manlike en 89 vroulike subjekte van wie 99 uit In institusie populasie geselekteer is, terwyl 54 geselekteer is uit In nie-institusie populasie. Die subjekte is in drie ouderdomskategorieë, naamlik 7 tot 21 jaar, 22 tot 59 jaar en 60 tot 84 jaar gegroepeer. Die ondersoekgroep se psigometriese data (die Goodenough Draw-A-Man en die Ou Suid-Afrikaanse Individuele Skaal bevindinge) gedateer 1985 tot 1990 is ontleed. Hierbenewens is 20 verstandelik gestremde inwoners se mensfiguur-tekeninge (60 tekeninge) wat tydens 1993 geadministreer is, ontleed om stereotiperende tekeninge en leerpotensiaal te ondersoek. Die resultate van die huidige studie is soos volg: Bepaling van die spesifieke grade van verstandelike gestremdheid (erg, matig en lig) illustreer dat die Goodenough Draw-A-Man-meetmiddel en die Ou Suid- Afrikaanse Individuele Skaal, verskil ten opsigte van die bepaling van spesifieke klassifikasies. Die McNemar-toets bevindinge dui op In betekenisvolle verskil tussen die twee meetmiddels (p < 0,05). Die ooreenkoms tussen hierdie twee intelligensie-meetmiddels ten opsigte van klassifikasie is soos volg: ligte graad (77,3%), matige graad (57,8%) en erge graad (47,9%). Die Chi-wadraattoets en Fisher se eksakte toets vergelyking tussen die 99 gelnstitusionaliseerdes en die 54 nie-gelnstitusionaliseerdes, sowel as tussen die 64manlike en 89 vroulike subjekte vir die drie ouderdomskategorieë, dui geen beduidende verskil in prestasie op die Goodenough Draw-A-Man-meetmiddel aan nie (p > 0,05). Die t-toets bevindinge met betrekking tot die ondersoek van stereotiperende mensfiguur-tekeninge, dui In beduidende verskil aan tussen die 20 toetslinge se prestasie op die eerste en tweede mensfiguur-tekeninge (t = -3,17, p < 0,05). Die subjekte het gemiddeld 2,4 tellings meer op die tweede tekening behaal Die t-toets bevindinge wat verband hou met die leerpotensiaal van verstandelik gestremdes, dui In beduidende verskil aan tussen die 20 toetslinge se prestasie voor en na die blootstelling aan In "perfekte" mensfiguurtekeninge (t = -5,26, P < 0,05). Die subjekte het gemiddeld 5,1 tellings meer op hul derde tekening behaal. 170 In Opsomming van die bevindinge is soos volg: dat die Goodenough Draw-A-Man-meetmiddel meer betroubaar is met die hoër funksionerende verstandelik gestremdes; dat veranderlikes soos institusionalisering, nieinstitusionalisering, geslag en ouderdom, nie In rol speel ten opsigte van hierdie groep verstandelik gestremdes se prestasie op die Goodenough Draw-A-Man nie; dat vir hierdie groep verstandelik gestremdes, stereotiperende tekeninge en modifikasie van hul kognitiewe strukture voorkom, soos in hul mensfiguurtekeninge aangedui.

Hovanec, Stanislav January 2009 (has links)
This diploma work initially conduct research in the area of descriptions and analysis of time series. The thesis then proceed to introduce the problems of technical analysis of price charts as well as indicators, price patterns and method of Pure Price Action. The method Pure Price Action is demonstrated in this work in two practical examples of its application to real businesses with a view to discovering and analyzing price patterns, as well as analysis and prediction of future price and financial evolution. This analysis is an introduction to the processes of successful business, following on from this we discuss the theme of Pattern Recognition and the Instance Based Learning method. The practical aspect of this work is carried out with the aid of a MATLAB applied algorithm for the analysis of the price pattern Correction for sale and purchase in dynamic time segments, specifically in trading price graphs, like those used for commodities or stock trading. For the analysis of time series we use the Pure Price Action method. The Instance Based Learning method is used by the algorithm to recognize price patterns. The created algorithm is verified on real data of a 5 minute time series of the US Dow Jones price charts for the years 2006, 2007, 2008. The achieved accuracy is evaluated with the aid of Equity Curves.

基於 EEMD 與類神經網路方法進行台指期貨高頻交易研究 / A Study of TAIEX Futures High-frequency Trading by using EEMD-based Neural Network Learning Paradigms

黃仕豪, Huang, Sven Shih Hao Unknown Date (has links)
金融市場是個變化莫測的環境,看似隨機,在隨機中卻隱藏著某些特性與關係。不論是自然現象中的氣象預測或是金融領域中對下一時刻價格的預測, 都有相似的複雜性。 時間序列的預測一直都是許多領域中重要的項目之一, 金融時間序列的預測也不例外。在本論文中我們針對金融時間序列的非線性與非穩態關係引入類神經網路(ANNs) 與集合經驗模態分解法(EEMD), 藉由ANNs處理非線性問題的能力與EEMD處理時間序列信號的優點,並進一步與傳統上使用於金融時間序列分析的自回歸滑動平均模型(ARMA)進行複合式的模型建構,引入燭型圖概念嘗試進行高頻下的台指期貨TAIEX交易。在不計交易成本的績效測試下本研究的高頻交易模型有突出的績效,證明以ANNs、EEMD方法與ARMA組成的混合式模型在高頻時間尺度交易下有相當的發展潛力,具有進一步發展的價值。在處理高頻時間尺度下所產生的大型數據方面,引入平行運算架構SPMD(single program, multiple data)以增進其處理大型資料下的運算效率。本研究亦透過分析高頻時間尺度的本質模態函數(IMFs)探討在高頻尺度下影響台指期貨價格的因素。 / Financial market is complex, unstable and non-linear system, it looks like have some principle but the principle usually have exception. The forecasting of time series always an issue in several field include finance. In this thesis we propose several version of hybrid models, they combine Ensemble Empirical Mode Decomposition (EEMD), Back-Propagation Neural Networks(BPNN) and ARMA model, try to improve the forecast performance of financial time series forecast. We also found the physical means or impact factors of IMFs under high-frequency time-scale. For processing the massive data generated by high-frequency time-scale, we pull in the concept of big data processing, adopt parallel computing method ”single program, multiple data (SPMD)” to construct the model improve the computing performance. As the result of backtesting, we prove the enhanced hybrid models we proposed outperform the standard EEMD-BPNN model and obtain a good performance. It shows adopt ANN, EEMD and ARMA in the hybrid model configure for high-frequency trading modeling is effective and it have the potential of development.

Learning Mathematics through Scientific Contents and Methods

Beckmann, Astrid 12 April 2012 (has links) (PDF)
The basic idea of this paper is to outline a cross-curricular approach between mathematics and science. The aim is to close the often perceived gap between formal maths and authentic experience and to increase the students’ versatility in the use of mathematical terms. Students are to experience maths as logical, interesting and relevant through extra-mathematical references. Concrete physical or biological correlations may initiate mathematical activities, and mathematical terms are to be understood in logical contexts. Examples: physical experiments can lead to a comprehensive understanding of the concept of functions and of the intersection of medians in triangles. Biological topics can lead to the concepts of similarity and proportion as well as to the construction of pie charts. In the European ScienceMath Project a variety of teaching modules was developed and tested in secondary schools.
