Research in Structural Equation Modeling Estimating for the Research and Development Performances of Biotechnology Industries in Taiwan.

Chen, Chun-Wei 19 July 2004 (has links)
¡@¡@At present, the essence situation of biotechnology industries in Taiwan lacks a market-oriented innovation system as sturdy as in advanced countries such as U.S.A., Canada, European Union, and Japan, et cetera. In the technology innovation processes including different gradations such as basic science, application research, technologies development and commercialization, all the R&D of biotechnology industries in Taiwan, ready for a innovation system, many strategies and projects with relation to R&D. However, in the commercialization gradation, having an unremarkable and approximate gap among biotechnology industries, venture capitals, authorities, academia, research institutes and corporations, with reciprocal effects to each other, that are inferior to these advanced countries. ¡@¡@The thesis research in estimating for the R&D performances of biotechnology industries in Taiwan, it makes use of the SPSS l0.0 and AMOS 5.0 for Windows to compute all raw data of sampling survey, after analyzing to demonstrate the structural equation modeling of estimating at the R&D performances of biotechnology industries of Taiwan, that the final result make sure of perfect goodness of fit for the model. The model could be transform into different structures to estimating at the R&D performances of all circles of biotechnology, to make up the gap between anticipated success and unexpected failure. ¡@¡@The conclusion reveals a special significance of business management, means that the R&D innovation system of biotechnology industries of Taiwan, should be operated in coordination with specific strategies and policies of the authorities, then certainty executing all science and technology projects to obtain the R&D performances in essence. In other words, the R&D innovation system of biotech industries of Taiwan still has many demands for investing more human resource, venture capital in R&D, having a well-arranged application for system resources, supplying the market with many well-appropriated laws and regulations, to communicating with international science and technology innovation systems in the world, et cetera. After accomplishing all as above, the R&D prospect of Taiwan¡¦s biotechnology industries will be well in the future.

Sociální důrazy předexilních proroků (Dějinné a teologické pozadí) / The social accents of the pre - exilic Prophets (Historical and Theological Background)

Šprta, Marian January 2018 (has links)
Resume: The work has a special theme of social accents of the prophets in the period before the exile. There is question what the chronology of the history of the royal era, in which the prophets spoke, was, what social processes were taking place at that time and how they are documented by biblical history and archeology. The first part of the work describes the historical situation in which these prophets were spreading their message. In this epoch the King's time was at the top of its peak, after which the crisis of transition from tribal society started into the urban civilization started which was finished by Israel's exile to Assyria and Judea in Babylon. In the northern empire peaks of the prosperity are considered to be the period during the reign of Achab and Jeroboam II. In the southern Empire it is the Uzziah's period. These peak times of prosperity, stemming from the state development, successful battles, and foreign trade, brought with an increase in social inequality and damage to social relations. The work depicts this time according to biblical sources, particulary the 1st and 2nd Books of Kings and the 2nd Paralipomenon. This section is followed by a chapter on interpretations by which Biblical archeology interprets archeological finds related to the time of the kingdom, especially from the...

Entwicklung und Evaluation eines Gewichtsfenstergenerators für das Strahlungstransportprogramm AMOS

Jakobi, Christoph 19 March 2018 (has links) (PDF)
Effizienzsteigernde Methoden haben die Aufgabe, die Rechenzeit von Monte Carlo Simulationen zur Lösung von Strahlungstransportproblemen zu verringern. Dazu gehören weitergehende Quell- oder Geometrievereinfachungen und die Gewichtsfenstertechnik als wichtigstes varianzreduzierendes Verfahren, entwickelt in den 1950er Jahren. Die Schwierigkeit besteht bis heute in der Berechnung geeigneter Gewichtsfenster. In dieser Arbeit wird ein orts- und energieabhängiger Gewichtsfenstergenerator basierend auf dem vorwärts-adjungierten Generator von T.E. BOOTH und J.S. HENDRICKS für das Strahlungstransportprogramm AMOS entwickelt und implementiert. Dieser ist in der Lage, die Gewichtsfenster sowohl iterativ zu berechnen und automatisch zu setzen als auch, deren Energieeinteilung selbstständig anzupassen. Die Arbeitsweise wird anhand des Problems der tiefen Durchdringung von Photonenstrahlung demonstriert, wobei die Effizienz um mehrere Größenordnungen gesteigert werden kann. Energieabhängige Gewichtsfenster sorgen günstigstenfalls für eine weitere Verringerung der Rechenzeit um etwa eine Größenordnung. Für eine praxisbezogene Problemstellung, die Bestrahlung eines Personendosimeters, kann die Effizienz hingegen bestenfalls vervierfacht werden. Quell- und Geometrieveränderungen sind gleichwertig. Energieabhängige Fenster zeigen keine praxisrelevante Effizienzsteigerung. / The purpose of efficiency increasing methods is the reduction of the computing time required to solve radiation transport problems using Monte Carlo techniques. Besides additional geometry manipulation and source biasing this includes in particular the weight windows technique as the most important variance reduction method developed in the 1950s. To date the difficulty of this technique is the calculation of appropriate weight windows. In this work a generator for spatial and energy dependent weight windows based on the forward-adjoint generator by T.E. BOOTH and J.S. HENDRICKS is developed and implemented in the radiation transport program AMOS. With this generator the weight windows are calculated iteratively and set automatically. Furthermore the generator is able to autonomously adapt the energy segmentation. The functioning is demonstrated by means of the deep penetration problem of photon radiation. In this case the efficiency can be increased by several orders of magnitude. With energy dependent weight windows the computing time is decreased additionally by approximately one order of magnitude. For a practice-oriented problem, the irradiation of a dosimeter for individual monitoring, the efficiency is only improved by a factor of four at best. Source biasing and geometry manipulation result in an equivalent improvement. The use of energy dependent weight windows proved to be of no practical relevance.

Die teologiese oorsprong van Ateisme

Green, Gerhardus Jakobus January 2017 (has links)
Navorsing oor veranderende konsepte van God toon aan dat die oorsprong van ateïsme na die skolastici van die laat-middeleeue teruggevoer kan word. Hierdie ondersoek poog om die verhouding tussen Johannes Duns Scotus se eenduidige konseptualisering van God en die verwerping van God deur moderne ateïste aan te toon. Die verandering van Thomas Aquinas se analogiese teologie na Johannes Duns Scotus se eenduidige ontologiese konseptualisering van God het `n groot invloed op nominalistiese teologie en die moderne realiteitsverstaan gehad. Nominaliste soos William van Occam het hierdie eenduidige konsep van God later kombineer en verder ontwikkel met die gevolg dat God later nie meer ontologiese voorkeur geniet het nie. Waar Aquinas die klem op God se transendensie gelê het, was daar ‘n toenemende neiging om God al hoe meer immanent te verstaan. ʼn God wat op dieselfde wyse as die mens bestaan, word dus ʼn “wese”, ʼn “getemde God”. Scotus en latere nominaliste het God se kwantitatiewe andersheid bo sy kwalitatiewe andersheid beklemtoon. Binne `n akademiese ruimte waarin die waarheid van die Christelike geloof en die outoriteit van die Rooms Katolieke Kerk nie bevraagteken is nie, was die invloed van hierdie teologiese veranderinge klein. Die Reformasie het dit egter verander, en alhoewel dit nie die bedoeling was nie, was die gevolg dat hierdie eenduidige konseptualisering van God deel van moderne teïsme geword het. Duns Scotus se invloed was so groot dat daar ook na hom as die stigter van moderniteit verwys kan word. Na die Reformasie het Descartes se cogito ergo sum daartoe gelei dat die rede alleen as bron van betekenis gegeld het. Hierdie ontwikkeling het voorkeur aan epistemologie bo ontologie gegee. Binne hierdie moderne realiteitsverstaan is daar nie plek vir ʼn eenduidige konseptualisering van God nie. Omdat ateïste juis hierdie konsep van God verwerp, is daar waarde in die bestudering van ateïsme. Sleutelwoorde: ateïsme, Thomas Aquinas, Johannes Duns Scotus, William van Occam, analogie van syn, eenduidige syn, Descartes, die Reformasie, Amos Funkenstein, Gavin Hyman, Brad Gregory, epistemologie, ontologie, skolastici, nominalisme, moderniteit, moderne teïsme. / Dissertation (MTh)--University of Pretoria, 2017. / Dogmatics and Christian Ethics / MTh / Unrestricted

The good, the bad, and the framed : A study of behavioral economics and the framing effect on tobacco free snus

Muleba, William January 2020 (has links)
This study sets out to explore attitudes and intentions towards nicotine product goods and how it is affected by the goal framing effect. The presence of this effect has been shown in the advertising of both green products and everyday products. The aim of this research is to explore whether or not this also holds true when it comes to unhealthy products, more precisely tobacco free all white nicotine products.    A quasi experimental study was conducted with the use of a fictitious brand of All-white tobacco. All 63 participants in the three different experimental groups of the study met the mandatory age requirement. One of the three groups received a positively framed advert, another received a negatively framed advert, whereas the last group acted as the control group and therefore received a neutral advertisement stimuli. All participants submitted their answers on a questionnaire created for this study, which was validated using Cronbach’s alpha and factor analysis.   The results suggest that the use of goal framing is beneficial when advertising nicotine product goods. Both positive and negative goal-framing showed a greater effect on purchase intention and product attitude than the control group. The negative goal-framing advert proved to be statistically different than the control group when measuring product attitude. Furthermore, the positively framed advert showed a statistically significant difference in effect on both product attitude and purchase intention compared to the control group.    The findings suggest that positively framed goal-framing has an effect on both attitudes and purchase intention, compared to the neutral stimuli. The negatively framed goal-framing had an effect on attitudes, compared to the neutral stimuli. The practical implication of this study could possibly be that when constructing advertisements for tobacco free snus products, it could be preferable to make use of the positive goal-framing effect in order to affect the consumers purchase intention and attitude towards the product.   This study has confirmed to some extent that the framing effect is a factor prevalent in the advertising of tobacco free products. For further research it would be highly interesting to delve deeper in comparing positive and negative goal-framing in order to find further evidence of which one has greater effect on consumers.

Development and validation of a hybrid measure of organisational communication satisfaction

Amanuel Gebru Woldearegay, Woldearegay, Amanuel Gebru 18 October 2013 (has links)
The purpose of the study was to identify and transform, as necessary, constructs of communication satisfaction and to develop a hybrid quantitative audit of organisational communication satisfaction for collectivist contexts that is both reliable and valid, using Amos Graphics for structural equation modelling. The objective was also to develop a full latent variable model and to test its fitness to the data collected from a random sample of civil servants across Addis Ababa’s civil service bureaus. The study comprised three sequential parts, namely pilot, exploratory factor analysis (EFA) (Main Study One) and confirmatory factor analysis (CFA) (Main Study Two). These were used as per the existing framework in instrument development and validation. The pilot study indicated the need for more robust data. After a series of tests, principal factor axis factoring with oblique rotation was used as the most appropriate for perceptual data, out of several options on the EFA menu. The initially hypothesised six-factor solution with the dimensions of horizontal communication, personal feedback, supervisory communication, communication climate, relational trust and job satisfaction was found to be unfit for the data on conceptual and statistical grounds and psychometric analyses which involved the use of eigenvalues and the scree plot. A more appropriate two-factor solution based on the more precise parallel analysis strategy was consistent with current research that communication satisfaction is best conceptualised in terms of informational and relational domains as operationalised using the EFA procedure. The two-factor solution led to the formation of a 17-item scale out of the original 30-item measure, with two latent dimensions namely relational satisfaction and informational satisfaction. The items of the new EFA-generated organisational communication satisfaction scale were renumbered consecutively and the scale was cross-validated on a xiv new sample of 288 civil servants from the Addis Ababa City Administration. The cross-validation necessitated model respecification and re-estimation. The respecified model underwent validation at different levels. All seven aspects of validity, namely content validity, construct validity, factorial validity, reliability, convergent validity, discriminant validity and nomological validity, were addressed and found to be adequate. However limitations are also indicated as avenues for further enquiry. / Communication Science / D. Litt. et Phil. (Communication)

Women in Xhosa drama : dramatic and cultural perspectives

Satyo, Priscilla Nomsa 03 1900 (has links)
Thesis (PhD)--University of Stellenbosch, 2001. / ENGLISH ABSTRACT: This study aims at highlighting a crucial aspect of Xhosa drama: The portrayal of the role women have been forced culturally to assume in society. A selection of Xhosa plays from three periods (1958 - 1965; 1974 - 1982; and 1988 - 1997) is examined. In the process of the study, the analysis and the interpretation of these dramas as well as the depiction of women characters is examined. Authors of the ten dramas under study advocate change through the powerful forces of gender stereotypes and culture distortions. The attributes that the authors commonly ascribe to women characters are passivity, irrationality, compliancy and incorrigibility. An examination of the reasons behind this proliferation of these female stereotypes and the lack of realistic women characters is undertaken. The study posits reasons why particular stereotypes appear in the works of several authors over a period of time. The women characters are products of social conditioning, that is, ideals or counter-ideals of the prevailing values of the authors' culture. They are a symbolic fulfillment of the writers' needs. The broad cultural perspectives of the authors also shape the texts they produce. These dramas treat issues and themes, which become central to the formal and structural ordering of the drama. Such themes have an impact at times on form and structure. In each case the ideology of the class represented by authors under study is indeed reflected in the text, to its detriment. The dominating themes in the ten dramas are forced marriages and women abuse. The authors are so preoccupied with injustices against women that they distort certain cultural aspects by, for example, exaggeration. Women are constantly depicted as victims, while there are no indications in the authors' depictions of women that perceptions of their cultural role and status are in reality undergoing changes. The thesis is arranged as follows: Chapter 1 introduces the aim, the scope, the theories and the methods of the study. Chapter 2 deals with the development of plot within episodes in the dramas of the first literary period (1958 - 1965). These episodes depict the different phases of the dramas. A critical evaluation of the dramas by motivating their positive and negative aspects is undertaken. Chapter 3 deals with the development of plot within episodes in the dramas of the second literary period (1974 - 1982). As in the first literary period, a critical evaluation of the dramas by motivating their positive and negative aspects is examined. Chapter 4 deals with the development of plot within episodes in the dramas of the third literary period (1988 - 1997). A critical evaluation of the dramas by motivating their good and bad points is undertaken. Chapter 5 deals with woman as character in Xhosa dramas under study. A detailed analysis of the main woman character in each drama is undertaken. Furthermore, a critical summary of how the woman has been portrayed in the dramas is presented. Chapter 6 presents depiction of Xhosa culture in the Xhosa dramas. From each drama, certain selected aspects of culture are explored and an investigation of the portrayal of these aspects is undertaken. Chapter 7 summarizes the findings of the study. / AFRIKAANSE OPSOMMING: Die doelstelling van hierdie studie is om 'n kern aspek van Xhosa drama te belig: die rolle wat vroue kultureel gedwing is om te vervul in die gemeenskap. 'n Seleksie Xhosa dramas vanuit drie tydperke (1958 - 1965; 1974 - 1982; en 1988 - 1997) word ondersoek. In die loop van die studie, ontleding en interpretasie van hierdie dramas word die uitbeelding van vroue karakters ook ondersoek. Die skrywers van die tien dramas wat bestudeer word, betoog vir verandering deur middel van die sterk kragte van stereopites en kultureelverwronge voorstellings. Die eienskappe wat die skrywers algemeen toeskryf aan vroue karakters is passiwiteit, irrasionele optrede, gehoorsaamheid en deugsaamheid. 'n Ondersoek na die redes vir die proliferasie van hierdie vroulike stereotipes en die tekortkoming aan realistiese vroue karakters in Xhosa dramas word uitgevoer in die studie. Die studie voer redes aan waarom bepaalde stereotipes in die werk van verskeie skrywers oor 'n tydperk verskyn: hulle vrouekarakters is die produk van sosiale kondisionering, dit wil sêm ideale of teen-ideale van die heersende waardes van die skrywer se kulturele agtergrond en 'n simboliese vervulling van die skrywer se behoeftes. Die algemene kulturele perspektiewe van die skrywers beïnvloed en vorm ook die tekste wat hulle lewer. Hierdie dramas behandel naamlik vraagstukke tematies wat sentraalook bepalend is ten opsigte van die vorm en struktuur van die drama. Sodanige temas het gevolglik in bepaalde gevalle 'n invloed op die vorm en struktuur van die drama. Voorts word die ideologie van die klas verteenwoordig deur die skrywers in elke geval gereflekteer en die teks tot bepaalde nadele daarvan. Die prominente temas in die tien dramas is gedwonge huwelike en vrouemishandeling. Die skrywers is so gepre-okkupeer met die ongeregtighede teenoor vroue dat hulle bepaalde kulturele aspekte verwring deur, byvoorbeeld, buitensporige voorstellings. Vroue word voortdurend voorgestel as slagoffers, terwyl daar feitlik geen aanduidings is in die skrywer se voorstelling van vroue, dat persepsies oor hulle kulturele rol en status inderwaarheid besig is om veranderinge te ondergaan. Die proefskrif is soos volg gestruktureer: Hoofstuk 1 gee die doelstellings, omvang, teorieë en metodes wat in die studie gevolg word. Hoofstuk 2 behandel die ontwikkeling van intrige binne verskillende episodes in die dramas van die eerste literêre periode (1958 - 1965). Hierdie episodes gee 'n uitbeelding van die verskillende fases van die dramas wat in die studie ondersoek word. 'n Kritiese evaluering word van die dramas gedoen deur die positiewe en negatiewe aspekte daarvan te motiveer. Hoofstuk 3 behandel die ontwikkeling van intrige binne die episodes van die dramas van die tweede literêre periode (1974 - 1982). Soos vir die eerste literêre periode, word 'n kritiese evaluering gedoen van die dramas deur onder andere die positiewe en negatiewe literêre aspekte daarvan te motiveer. Hoofstuk 4 ondersoek die ontwikkeling van die intrige binne die episodes in die dramas van die derde literêre periode (1988 - 1997). Die kritiese evaluering van hierdie dramas sluit, soos vir die vorige periodes, 'n gemotiveerde beskouing in van die positiewe en negatiewe aspekte. Hoofstuk 5 ondersoek die vrou as karakter in die Xhosa dramas wat bestudeer word. 'n Gedetaileerde analise van die hoof-vroue karakters in elke drama word gedoen. Daarna word 'n kritiese oorsig aangebied van hoe die vrou voorgestel word in die dramas wat bestudeer is. Hoofstuk 6 bied 'n uitbeelding van Xhosa kultuur in die dramas wat ondersoek is. Bepaalde aspekte van kultuur word vir elke drama ondersoek en die uitbeelding van hierdie kultuur aspekte word behandel. Hoofstuk 7 bied 'n opsomming van die belangrikste bevindinge van die studie.
