While assessing emotions, behaviors or performance of preschoolers and young children, scores from adults such as parent psychiatrist and teacher ratings are used rather scores from children themselves. Data from parent ratings or from parents and teachers are often nested such as students are within teachers and a child is within their parents. This popular nested feature of data in educational, social and behavioral sciences makes measurement invariance (MI) testing across informants of children methodologically challenging. There was lack of studies that take into account the nested structure of data in MI testing for multiple adult informants, especially no simulation study that examines the performance of different models used to test MI across different raters. This dissertation focused on two specific nesting data types in testing MI between adult raters of children: paired and partial nesting. For the paired data, the independence assumption of regular MI testing is often violated because the two informants (e.g., father and mother) rate the same child and their scores are anticipated to be related or dependent. The partial nesting data refers to the research situation where teacher and parent ratings are compared. In this scenario, it is common that each parent has only one child to rate while each teacher has multiple children in their classroom. Thus, in case of teacher and parent ratings of the same children, data are repeated measures and also partially nested. Because of these unique features of data, MI testing between adult informants of children requires statistical models that take into account different types of data dependency. I proposed and evaluated the performance of the two statistical models that can handle repeated measures and partial nesting with several simulated research scenarios in addition to one commonly used and one potentially appropriate statistical models across several research scenario. Results of the two simulation studies in this dissertation showed that for the paired data, both multiple-group confirmatory factor analysis (CFA) and repeated measure CFA models were able to detect scalar invariance most of the time using Δχ2 test and ΔCFI. Although the multiple-group CFA (Model 2) was able to detect scalar invariance better than the repeated measure CFA model (Model 1), the detection rates of Model 1 were still at the high level (88% - 91% using Δχ2 test and 84% - 100% using ΔCFI or ΔRMSEA). For configural invariance and metric invariance conditions for the paired data, Model 1 had higher detection rate than Model 2 in almost examined research scenario in this dissertation. Particularly while Model 1 could detect noninvariance (either in intercepts only or in both intercepts and factor loadings) than Model 2 for paired data most of the time, Model 2 could rarely catch it if using suggested cut-off of 0.01 for RMSEA differences. For the paired data, although both Models 1 and 2 could be a good choice to test measurement invariance, Model 1 might be favored if researchers are more interested in detecting noninvariance due to its overall high detection rates for all three levels (i.e. configural, metric, and scalar) of measurement invariance. For scalar invariance with partially nested data, both multilevel repeated measure CFA and design-based multilevel CFA could detect invariance most of the time (from 81% to 100% of examined cases) with slightly higher detection rate for the former model than the later. Multiple-group CFA model hardly detect scalar invariance except when ICC was small. The detection rates for configural invariance using Δχ2 test or Satorra-Bentler LRT were also highest for Model 3 (82% to 100% except only two conditions with detection rates of 61%), following by Model 5 and lowest Model 4. Models 4 and 5 could reach these rates only with the largest sample sizes (i.e., large number of cluster or large cluster size or large in both factors) when the magnitude of noninvariance was small. Unlike scalar and configural invariance, the ability to detect metric invariance was highest for Model 4, following by Model 5 and lowest for Model 3 across many conditions using all of the three performance criteria. As higher detection rates for all configural and scalar invariance, and moderate detection rates for many metric invariance conditions (except cases of small number of clusters combined with large ICC), Model 3 could be a good candidate to test measurement invariance with partially nested data when having sufficient number of clusters or if having small number of clusters with small ICC. Model 5 might be also a reasonable option for this type of data if both the number of clusters and cluster size were large (i.e., 80 and 20, respectively), or either one of these two factors was large coupled with small ICC. If ICC is not small, it is recommended to have a large number of clusters or combination of large number of clusters and large cluster size to ensure high detection rates of measurement invariance for partially nested data. As multiple group CFA had better and reasonable detection rates than the design-based and multilevel repeated measure CFA models cross configural, metric and scalar invariance with the conditions of small cluster size (10) and small ICC (0.13), researchers can consider using this model to test measurement invariance when they can only collect 10 participants within a cluster (e.g. students within a classroom) and there is small degree of data dependency (e.g. small variance between clusters) in the data.

This master thesis deals with topics related to the task whether customers are able to recognize a difference between products. First, testing of equivalence and non-inferiority is discussed in detail. It is an important tool when verifying that two products are equivalent or that a new product is not substantially worse than a current product. Afterwards, Thurstone's approach is introduced as a way to evaluate the impact of a stimulus on human senses. Subsequently, using the previous chapters, there is a detailed discussion dealing with three standards wi- dely used in practice in the case when someone needs to apply sensory evaluation to verify whether customers are able to recognize a difference between products. In particular, these are duo-trio, triangle and paired comparison tests. There is a thorough explanation of their statistical base and the tests are compared accor- ding to their power. Furthermore, an approach based on the Thurstone's theory is introduced as an alternative to the standard methods. Moreover, this thesis introduces Saaty's approach to the estimation of a priority vector, which is a useful tool to compare, to order or to choose the best one from n objects. We also introduce another approach to estimation of a priority vector which is based on Saaty's idea. 1

Plasma gasification experiments were conducted on sucrose and crushed macadamia nutshells. The pilot-scale plasma gasification system used comprises a 15 kW DC plasma torch fitted to a 5 L gasification reactor. The DC plasma torch has an efficiency of ~30 % with most of the energy lost in the torch anode. For the macadamia nutshells, the plasma input-power was set at 9, 11 and 14 kW. At each power input setting, four different feed rates were investigated, namely 0.5, 0.7, 1.04 and 1.14 kg/h. It was observed that as the power increases, conversion increases from 48 % at 9 kW to higher than 80 % at 14 kW. It was also observed that higher mass feed rates increase the conversion. The lower heating values of the syngas produced during gasification increased with higher power inputs and higher feed rates. At a feed rate of 1 kg/h, the maximum calorific power value was 3.45 kW, at a torch setting of 14 kW. The highest power values obtained was slightly more than 4 kW. The effect of equivalence ratio (ER) was evaluated on the plasma gasification of sucrose. ER values of 1 and 2 were investigated. With an ER of 1, the CO/H2 ratio was 1.8 and the CO/CO2 ratio was 109. With an ER of 2, the CO/H2 ratio was 1.73, and the CO/CO2 ratio 18. As expected, an increase in ER enhances the formation of CO2. A low ER thus results in higher syngas quality. At equivalent conditions the homogenous, crystalline sucrose yielded a CO/CO2 ratio of 109, significantly higher than the 29 for plasma gasification of the macadamia nut shells. A contributing factor to having better quality syngas, was the smaller the average particle diameter of the sucrose, 0.4 mm, compared to the 10 mm of the crushed macadamia nut shells was. Another contributing factor could be that the available carbon in the macadamia nut shells structure are more strongly bonded than in sucrose. For additional insight, kinetic data for the pyrolysis of sucrose, fructose and glucose were obtained using a TGA-FTIR hyphenated system, at much lower heating rates than anticipated in plasma system, and TGA-DTG experiments on macadamia nut shells. Dynamic studies were performed on sucrose, fructose and glucose at heating rates of 5, 10, 15, 20 and 50 °C/min in an atmosphere of nitrogen flowing at 50 mL/min, and for the macadamia shell at heating rates of 5, 10 and 20 °C/min in an atmosphere of nitrogen flowing at 50 mL/min. The sugars yielded 80 % to 85 % conversion into gaseous products, while the conversion of the shells approached 90 %; the residue was biochar. The FTIR spectra showed the major products that form from the pyrolysis of sugars to be CO2, H2O, along with large quantities C-H-O-containing compounds, amongst them C5H4O2 and C6H6O3. The latter two compounds are probably condensible. / Dissertation (MEng)--University of Pretoria, 2020. / Chemical Engineering / MEng / Unrestricted

This diploma thesis is focused on the analysis of German language equivalents of Czech proverbs in the dictionary of František Čermák Dictionary of Czech Phraseology and Idiomatics 4 (DCPI 4). The introductory part of the thesis characterizes proverbs as a phraseological unit and reflects the current state of Czech and German paremiography on the basis of selected dictionaries. Another theoretical starting point is the issue of equivalence, which in contrastive phraseology or, more precisely, paremiology plays an important role. The analytical part contains of multi-level analysis of German language equivalents of the Czech paremiological minimum in DPCI 4. Equivalents were verified using Hugo Siebenschein's Great Czech-German Dictionary, Duden 11, Hans Schemann's German Idiomatics, the corpuses InterCorp and DeReKo and the Google full-text search engine. The aim of this thesis is to evaluate the current state of German-language equivalents in DCPI 4 and offer possible suggestions for improvement. The chosen approach is therefore not only contemplative, but also constructive. Keywords lexikology, phraseology, paremiology, lexicography, phraseography, Corpus Linguistics, equivalence

We present several results for growth functions of ideals of different com- binatorial structures. An ideal is a set downward closed under a containment relation, like the relation of subpartition for partitions, or the relation of induced subgraph for graphs etc. Its growth function (GF) counts elements of given size. For partition ideals we establish an asymptotics for GF of ideals that do not use parts from a finite set S and use this to construct ideal with highly oscillating GF. Then we present application characterising GF of particular partition ideals. We generalize ideals of ordered graphs to ordered uniform hypergraphs and show two dichotomies for their GF. The first result is a constant to linear jump for k-uniform hypergraphs. The second result establishes the polynomial to exponential jump for 3-uniform hypergraphs. That is, there are no ordered hypergraph ideals with GF strictly inside the constant-linear and polynomial- exponential range. We obtain in both dichotomies tight upper bounds. Finally, in a quite general setting we present several methods how to generate for various combinatorial structures pairs of sets defining two ideals with iden- tical GF. We call these pairs Wilf equivalent pairs and use the automorphism method and the replacement method to obtain such pairs. 1

Orientador: Anise de Abreu Gonçalves D'Orange Ferreira / Resumo: A leitura do texto clássico latino é um dos principais objetivos daqueles que se dedicam ao estudo da língua materna dos antigos romanos. Além de ler esses textos, compreendidos como objetos de significação, únicos em sua forma de expressar a cultura, pode também o especialista se dedicar a não menos importante tarefa de divulgar a cultura clássica àqueles que não dominam o idioma. A tradução torna-se, assim, uma atividade de destaque, na medida em que se constitui uma importante forma de conservação e transmissão da herança linguística, literária e cultural legada pela civilização romana. A prática tradutória é muito presente na Área dos Estudos Clássicos, assim como trabalhos acadêmicos que a têm como objetivo e versam sobre o tema. Entretanto, um levantamento bibliográfico de estudos realizados nessa área indica que a maioria destes trabalhos são desenvolvidos no campo dos estudos literários, tratando de questões referentes a literariedade do texto clássico, mas carecendo de uma reflexão sobre a linguagem que se paute de modo mais aprofundado na teoria linguística moderna. Tomando, a partir de Brodsky (1994, p. 86), a concepção de tradução como “a procura de um equivalente, e não de um substituto”, propõe-se empreender uma reflexão sobre a tradução de textos latinos, tendo como base os conhecimentos fornecidos pela teoria moderna da linguagem, em especial por Saussure e Hjelmslev, com vistas a compor a discussão sobre o tema na Área de Clássicas.

Besides reading these texts, understood as signification objects, unique in their way of express the culture, specialists can also dedicate themselves to the no less important task of disseminating the Classical Culture to those who do not dominate the language. The translation becomes, thus, a prominent activity, as far as it is an important way of conservation and transmission of linguistic, literary and cultural heritage bequeathed by the Roman civilization. The translation practice is very present in the field of Classical Studies, as well as academic works that have it as an objective and, for that reason, deal with the theme. Nonetheless, a bibliographic survey of studies carried out in this Area indicates that the most of these works are based on literary studies, dealing with the literary aspects of the classical text, but lacking a reflection about language that address more deeply the modern language theory. Taking Brodsky (1994, p.86) translation concept as “the pursuit of an equivalent, not a substitute”, it is proposed to reflect upon classical Latin texts translation, considering the knowledge provided by the modern language theory, mainly by Saussure and Hjelmslev, in order to integrate the discussion about the theme in the field of Classics. The saussurian concept of value is in the spotlight to think about the notion of equivalence in translation... (Complete abstract click electronic access below) / Mestre

Background and Aim: Although inroads are currently being made into research in the area of organisational energy, an exhaustive search of the literature has indicated that research into measurement instruments which are applicable in the South African context is scant, with two empirical studies having been conducted in South Africa on organisational energy (Derman, Barkhuizen, & Stanz, 2011; Lamberti, 2010). As there is minimal research into organisational energy measures which are most appropriate for use in the South African context, this study explores the reliability and validity of the Productive Energy Measure (PEM) (Bruch, Cole & Vogel, 2005) in the South African context. This study also adds to the existing knowledge on the Energy Scapes Profile (ESP) (Tosey & Llewellyn, 2002) in the South Africa. Method: A cross-sectional survey research design is followed with data being collected from employees (N=303) from South African institutions. The ESP (Tosey & Llewellyn, 2002), and the PEM (Cole, Bruch & Vogel, 2011) are administered. Exploratory Factor Analysis, Confirmatory Factor Analysis, construct equivalence item bias analyses, Analysis of Variance, Multivariate Analysis of Variance and Regression Analysis are applied. Results:  Confirmatory factor analysis (CFA) of the ESP reveals that both a seven-factor and a one-factor model were inconclusive. Subsequent Exploratory factor analysis (EFA) reveals a one-factor structure. The theoretical sub-scales of the ESP show a high level of internal consistency.  The results of the CFA for the PEM clearly reveal a three-factor model. The three theoretical sub-scales show an excellent level of reliability. Statistically significant differences are found in the productive organisational energy levels of employees based on job level, home language, years in current job and the PEM dimensions.  Results of the regression analysis indicate that a statistically significant relationship exists between organisational energy and productive organisational energy. Practical Relevance: As far as could be determined, this is the first study to make use of the PEM in South Africa. The study attempts to identify which measure of organisational energy is most appropriate for use in the South African context, and makes a contribution to the body of knowledge surrounding organisational energy measurement instruments in the South African context. Furthermore, the study of measures of organisational energy which can be applied in the South African context provides assistance to those interested in measuring organisational energy in the workplace. / Dissertation (MCom)--University of Pretoria, 2011. / Human Resource Management / Unrestricted

Inversion and Depth Range of Dipole Electromagnetic Induction Measurements in Geophysics Fernando César Moura de Andrade Institute of Hydrogeology, Engineering Geology and Applied Geophysics Faculty of Science, Charles University Electromagnetic induction geophysical methods are, basically, composed by a transmitter which produces a magnetic field and a set of receivers which measure the primary magnetic field, from the transmitter, superimposed by secondary magnetic fields inducted in the subsurface. Equipment operating at, relatively, low frequencies and with short distances between the transmitter and the receivers are usually called conductivity meters and operate at low inductions numbers. The depth of investigation, in such kind of equipment, depends mainly on the transmitter-receiver distance, on the orientations of the magnetic dipoles and the height of the instrument from the ground, in order that a depth sounding can be done changing these parameters in a single measurement location. Making a series of these multi-configuration measurements, two-dimensional, or even three-dimensional surveys, can be performed and, subsequently, inverted in order to produce an image of the subsurface of the earth. Forward modelling and inversion of multi-configuration electromagnetic induction data can be made...

We show that any Borel action on a standard Borel space of a group which is topologically isomorphic to the sum of a countable abelian group with a countable sum of lines and circles induces an orbit equivalence relation which is hypersmooth. We also show that any Borel action of a second countable locally compact abelian group on a standard Borel space induces an orbit equivalence relation which is essentially hyperfinite, generalizing a result of Gao and Jackson for the countable abelian groups.

Syftet med detta examensarbete är att fördjupa förståelsen för hur studie- och yrkesvägledare ser på sitt uppdrag med särskilt fokus på hur de uppfattar uppdragets likvärdighet. Intresset för detta område har väckts under vår utbildning till studie- och yrkesvägledare på Stockholms universitet och utifrån de diskussioner kring vägledning och vägledares uppdrag som förs i samhället idag. Genom en kvalitativ intervjustudie med examinerade vägledare erhölls en fördjupad förståelse för studie- och yrkesvägledares syn på sitt uppdrag och likvärdigheten i det. Resultatet visar på att vägledarna upplever att de saknar tid och resurser för att genomföra sitt uppdrag som de skulle önska samt att även om de arbetar så likvärdigt de förmår så upplever de inte att studie- och yrkesvägledningen är nationellt likvärdig idag. Det konstateras också att SOU 2019:4 tas emot mycket positivt av vägledarna och att de önskar att förslagen som denna utredning lägger fram skulle lagstadgas. Resultatet har analyserats utifrån Careershipteorin vilket lett till slutsatsen att vägledarnas syn på sitt uppdrag är tätt sammanlänkat med deras handlingshorisont. / The purpose of this dissertation is to deepen the understanding of how career guidance counsellors view their work assignation in particular how they perceive the equivalence within career guidance. The interest in this topic arose during our education to become career guidance counsellors at Stockholm University and was influenced by the current discourse regarding career guidance and career counsellors' work assignations in general. Through a qualitative interview study with educated career guidance counsellors, an in-depth understanding of career guidance counsellors' views on their work assignation and the equivalence within it was obtained. The study concludes that career guidance counsellors experience a lack of time and resources which prevents them from carrying out their work in the way they would like. Though they try to carry out their assignations with as much equivalence as possible, they do not feel that career guidance and counselling is nationally equivalent today. Furthermore, the study concludes that the SOU 2019:4 is perceived very positively by the career guidance counsellors and that they wish the proposals presented within it would be legislated. The results have been analysed using the Careership theory, which has led to the conclusion that the career guidance counsellors’ views on their work assignation are closely linked to their horizons for action.
