The purpose of this study was to develop an economic career choice instrument for grade 121earners, which conforms with the requirements of cultural fairness, validity and reliability. The various facets of adolescent development were analysed from the literature. Self-knowledge (identity) and career knowledge were analysed from various theoretical perspectives. The various facets of adolescent development had a direct influence on the career choice of learners. These facets served as a basis for the development of the different sections for the career choice instrument. In the empirical study a survey was conducted involving 321 grade 12 learners randomly selected from secondary schools in the Potchefstroom region. These learners completed the newly developed instrument. The reliability of the career choice instrument was determined by using the Cronbach Alpha Coefficient. Factor analysis were used to determine the validity of each section of the instrument. In order to determine whether the career choice instrument was culturally fair, a series of one-way ANOVAS, followed by Tukey tests were performed, whereafter effect sizes were determined. In the study good reliability indices were obtained for all sections of the measuring instrument. The reliability indices obtained from the Cronbach Alpha Coefficients, coincided relatively well with the reliability indices obtained for the MB-10 (Meyer Interest Questionnaire), the Jung Personality questionnaire and the LISRES-Y. Concerning the cultural aspect, the different race groups, white, black and coloured learners, differed significantly in respect of social development and values. Recommendations for further research for the use of the instrument in teaching practice are formulated from the research results, in particular with reference to the designing of a career choice instrument. / Thesis (Ph.D. (Education))--Potchefstroom University for Christian Higher Education, 2001

<p>Det allt mer globala företagandet har bidragit till skapandet av IFRS 7, vilket är en gemensam standard för upplysningar rörande risker för finansiella instrument. För noterade bolag med räkenskapsår som börjar 1 januari 2007 är den nya standarden obligatorisk. Detta innebär att även ickefinansiella företag måste tillämpa den.</p><p>Studien inriktar sig på att analysera hur svenska industriföretag har tillämpat de nya kraven på redovisning som IFRS 7 ställer på upplysningarna för kredit-, likviditets- samt marknadsrisk. Data har inhämtats från 2007 års årsredovisningar och författarna avser att utgå från hur de kvalitativa egenskaperna relevans, begriplighet, tillförlitlighet och jämförbarhet påverkas av införandet.</p><p>Författarna kommer i slutsatserna fram till att de studerade industriföretagen lever upp till de högre kraven på upplysningar som behandlar deras finansiella instrument, men att skillnader i omfattning och upplägg förekommer. De kvalitativa egenskaperna påverkas övervägande positivt. Ett mer specificerat regelverk eller en utstakad praxis skulle leda till ännu bättre kvalité för användarna.</p>

The purpose of this thesis is to investigate new instrument technology to enhance the capabilities of 8-m telescopes. This thesis first describes the theory, design, construction, and testing of an immersed grating. Immersed gratings can be used to provide R≥ 10(^4) with a multi-object and/or integral field spectrograph on an 8-m telescope. Immersed gratings allow high resolution to be achieved whilst maintaining the required pupil size at a level similar to that on 4-m telescopes. This thesis describes laboratory tests which verify that immersed gratings provide high resolution. The throughput penalty in using an immersed grating is shown to be small with losses due to air-glass reflections, which can be eliminated with antireflection coatings, and metal-dielectric losses. This work demonstrates that immersed gratings provide a good method to reach R=10(^4) (and above) with a multi-aperture spectrograph on an 8-m telescope. The second part of this thesis describes the construction of a microlens-fibre based integral field unit (IFU): the SMIRFS-IFU. This instrument provides a unique J and H-band integral field capability for use with the CGS4 spectrograph at UKIRT. The optical design, assembly, laboratory testing, and telescope commissioning of the SMIRFS-IFU are described. The microlens arrays for use with SMIRFS-IFU were tested in detail and found to provide excellent image quality but with some scattered light. The assembly of the SMIRFS-IFU was achieved with high precision. The overall performance of the SMIRFS-IFU was found to be high and close to theoretical expectations. This instrument demonstrates that the technology of microlenses linked to fibres does provide a means of constructing high performance (i.e. high throughput, high spatial and spectral resolution) IFUs. Integral field spectroscopy is even more important for 8-m telescopes to take advantage of their enormous fight gathering power. The SMIRFS-IFU is an important upgrade to CGS4 to perform high spatial resolution integral field spectroscopy.

The basic problem of this study Is whether or not the semantic differential attitude instrument may be used to measure attitude Intensity. The method of determining this is to use an instrument which is known to measure attitude Intensity in conjunction with the semantic differential and determine whether or not a significant correlation exists between the two.
