description: Digital watermarking of multimedia content has been proposed as a method for different applications such as copyright protection, content authentication, transaction tracking and data hiding. In this thesis, we propose a lossless watermarking approach based on Discrete Cosine Transform (DCT) for a new application of watermarking. A depth map obtained from a stereoscopic image pair is embedded into one of the two images using a reversible watermarking algorithm. Different from existing approaches which hide depth map in spatial domain, the depth information is hidden in the quantized DCT domain of the stereo image in our method. This modification makes the watermarking algorithm compatible with JPEG and MPEG-2 compression. After the investigation of the quantized DCT coefficients distribution of the compressed image and video, The bit-shift operation is utilized to embed the depth map into its associated 2D image reversibly for the purpose of achieving high compression efficiency of the watermarked image and/or video and high visual quality of stereo image and/or video after the depth map is extracted. We implement the proposed method to analyze its performance. The experimental results show that a very high payload of watermark (e.g. depth map) can be embedded into the JPEG compressed image and MPEG-2 video. The compression efficiency is only slightly reduced after the watermark embedding and the quality of the original image or video can be restored completely at the decoder side.

description: In this thesis, the connection between subsidies, especially based on the KfW program energy-efficient renovation 2005 to 2017, and the renovation activity is analyzed based on the renova-tion rate in the period 2000 to 2015. Both the renovation rate and the subsidy rate increased during the period under review, with heating systems being renovated and subsidized signifi-cantly more frequently than the building envelope. When differentiating between building types, multi-family houses are more frequently fully modernized than single-family houses, so that the renovation rate is higher, and a higher share of the subsidies is spent on this. Among the owners, a clear renovation backlog can be observed for the homeowner association. Insti-tutional owners have made the most progress in renovation. Regional differences are visible, with the new federal states in particular lagging behind the old federal states in terms of reno-vation rates and the use of subsidies. Overall, a link between subsidies and renovation activity can be found at all levels investigated. How strong the impact is, however, also depends on other economic and social factors.
The Rational Design and Use of Novel Small-Molecule Ice Recrystallization Inhibitors for the Cryopreservation of Hematopoietic Stem Cells and Red Blood Cells

description: Over the past few decades, there has been an increase in the development of new cellular therapies used for the treatment of various conditions. Thus, the rapid development of therapies requiring transfusion and transplantation of cells has resulted in a need to preserve these cellular therapy products. Cryopreservation is the only currently used method for the long-term storage of cells. The most commonly used cryoprotectants are 10% dimethyl sulfoxide (DMSO) for hematopoietic stem cells (HSCs) and 40% glycerol for red blood cells (RBCs). DMSO fails to protect the functionality of HSCs after cryopreservation and therefore, up to 20% of HSC transplantations fail to engraft. The glycerol in thawed RBC units must be removed to <1% to prevent intravascular hemolysis which is time-consuming. Thus, there is an urgent need to develop improved cryoprotectants for HSCs and RBCs. DMSO and glycerol are unable to control ice recrystallization which is a major source of cellular injury during cryopreservation. Therefore, compounds with the ability to inhibit ice recrystallization could represent a new class of cryoprotectant with a novel mechanism of action. This thesis focuses on the rational design of small-molecule ice recrystallization inhibitors. The key structural attributes required for ice recrystallization inhibition (IRI) activity are investigated. The amphiphilic balance required for IRI activity is explored. Furthermore, two new classes of small-molecule IRIs containing aromatic rings were rationally designed. As a result, several very highly IRI active molecules were discovered. The use of IRIs to improve the cryopreservation of HSCs and RBCs was explored. A number of IRIs improved the post-thaw functionality of HSCs. Supplementation of the current cryoprotectant solution with IRIs resulted in an increase in CFU recovery and frequency of multipotent progenitors. This would reduce the percentage of engraftment failure and allow for a larger proportion of cord blood banks’ inventory to provide an adequate dose for patients requiring transplants. Several IRIs were found to be effective cryoprotectants for RBCs with reduced amounts of glycerol. This could reduce the deglycerolization time for RBCs. These results demonstrate the potential of small-molecule IRIs to improve the current cryopreservation procedures for important cellular therapy products.

description: The motif discovery problem is becoming increasingly important for molecular biologists as new sequencing technologies are producing large amounts of data, at rates which are unprecedented. The solution space for DNA motifs is too large to search with naive methods, meaning there is a need for fast and accurate motif detection tools. We propose MotifGP, a multiobjective motif discovery tool evolving regular expressions that characterize overrepresented motifs in a given input dataset. This thesis describes and evaluates a multiobjective strongly typed genetic programming algorithm for the discovery of network expressions in DNA sequences. Using 13 realistic data sets, we compare the results of our tool, MotifGP, to that of DREME, a state-of-art program. MotifGP outperforms DREME when the motifs to be sought are long, and the specificity is distributed over the length of the motif. For shorter motifs, the performance of MotifGP compares favourably with the state-of-the-art method. Finally, we discuss the advantages of multi-objective optimization in the context of this specific motif discovery problem.

description: This chapter sets out a short history of the development of soil protection law, focusing on the international legal aspects. It introduces the notion that soil, as a non-renewable natural resource, performs a range of functions, in terms of biodiversity conservation, food security and health. It argues that soil degradation needs to be treated on the same level as the loss of biodiversity and the adverse effects of climate change. It also urges that soil should be regarded as a common concern of humankind, and that over-arching international, regional and national regulation is required. It explores recent developments relevant to soil, including those found in the Outcome Document of the Rio de Janeiro 2012 Conference on Environment and Development ĺThe Future We Want̷, as well as the Sustainable Development Goals and Targets that were approved by the UN General Assembly in September 2015.

Modified Spiegler-Kedem Model to Predict the Rejection and Flux of Nanofiltration Processes at High NaCl Concentrations

description: Current nanofiltration (NF) models are based on the “diluted solution” assumption and cannot successfully predict permeate fluxes at high salt concentrations. The reasons behind the strong differences between the predicted and observed fluxes are still not fully understood. In this work, it is proposed that these deviations are possibly caused by the electrical charges inside the membrane pores. At a nanoscale level, the complex electrostatic interactions between the highly confined charged solutes and the charges inside membrane pores contribute to flow retardation and this phenomena can be characterized using an additional resistance factor, which is defined as the electric resistance factor in this study. To this extent, experiments were carried out with aqueous sodium chloride (NaCl) solutions in a wide range of concentrations (0.05 – 1.96 M) using two commercial membranes (NF270 and Desal-5 DL). Salt retention was fitted and analysed by means of the classical Spiegler-Kedem model (SK). The model has been modified to include the proposed empirical electric resistance factor, Relec, to account for this additional hydrodynamic flow resistance. The modified Spiegler-Kedem model (MSK) was verified by fitting experimental data at relatively low salt concentration to obtain model parameters and then comparing the model prediction with experimental data at higher concentrations. A mathematical equation was developed to describe the dependence of an important model parameter, reflection coefficient (σ), on operational conditions such as pressure and bulk salt concentration. The thesis also discussed the mechanisms of NF separation, highlighting the electrostatic interaction between the co-ions and the membrane charges in the confined nano-environment inside the NF membrane pores.

Multi-modal Emotion Categorization in Oral History Interviews

Year: 2023

description: This thesis proposes a multi-label classification approach using the Multimodal Transformer (MulT) [80] to perform multi-modal emotion categorization on a dataset of oral histories archived at the Haus der Geschichte (HdG). Prior uni-modal emotion classification experiments conducted on the novel HdG dataset provided less than satisfactory results. They uncovered issues such as class imbalance, ambiguities in emotion perception between annotators, and lack of representative training data to perform transfer learning [28]. Hence, the objectives of this thesis were to achieve better results by performing a multi-modal fusion and resolving the problems arising from class imbalance and annotator-induced bias in emotion perception. A further objective was to assess the quality of the novel HdG dataset and benchmark the results using SOTA techniques. Through a literature survey on the challenges, models, and datasets related to multi-modal emotion recognition, we created a methodology utilizing the MulT along with a multi-label classification approach. This approach produced a considerable improvement in the overall emotion recognition by obtaining an average AUC of 0.74 and Balanced-accuracy of 0.70 on the HdG dataset, which is comparable to state-of-the-art (SOTA) results on other datasets. In this manner, we were also able to benchmark the novel HdG dataset as well as introduce a novel multi-annotator learning approach to understand each annotator’s relative strengths and weaknesses for emotion perception. Our evaluation results highlight the potential benefits of the novel multi-annotator learning approach in improving overall performance by resolving the problems arising from annotator-induced bias and variation in the perception of emotions. Complementing these results, we performed a further qualitative analysis of the HdG annotations with a psychologist to study the ambiguities found in the annotations. We conclude that the ambiguities in annotations may have resulted from a combination of several socio-psychological factors and systemic issues associated with the process of creating these annotations. As these problems are also present in most multi-modal emotion recognition datasets, we conclude that the domain could benefit from a set of annotation guidelines to create standardized datasets.

In-situ-Untersuchungen an den verwendeten Festbett-Rohrreaktoren fokussieren sich aktuell insbesondere auf die Katalysatorstruktur. In dieser Arbeit wird ein neuartiges Verfahren zur Untersuchung mechanistischer Aspekte der eisenbasierten Fischer-Tropsch-Reaktion vorgestellt. Grundprinzip ist dabei die ortsaufgelöste Messung von Reaktionsprofilen, welche es ermöglicht, spezielle Aspekte wie die Umwandlung gebildeter Primärprodukte in Sekundärreaktionen zu beleuchten. Dazu wird im Vorfeld ein im Hinblick auf die Produktbildung optimiertes Katalysatorsystem entwickelt sowie die Reproduzierbarkeit des neuartigen Messverfahrens verifiziert. Darauf aufbauend wird dann der Einfluss der Betriebsbedingungen auf die Reaktionsprofile diskutiert und die Rolle spezieller Sekundärreaktionen wie der sekundären Hydrierung oder Reinsertion bewertet.

description: Large numbers of immigrants have a considerable effect on the size of the population but very little effect on its age structure. Despite this demographic fact, many advocates argue that high immigration is an effective way to keep a population young. New survey data show that they may have had some influence on public attitudes. Worry about the ageing of the population ranked among the top three concerns held by Australian voters in 2005, and those who had this concern tended to be more supportive of immigration than those who did not.

description: Finite mixture model-based clustering is a popular method to perform unsupervised learning, however the classic approach for parameter estimation, the expectationmaximization algorithm, is quite susceptible to converging to, at times extremely poor, local maxima. Recently, swarm-based algorithms have gained popularity in a number of optimization scenarios. One such swarm-based optimization procedure, the artificial bee colony, incorporates both local searching and multiple solution generating to explore the parameter space. Herein, we propose hybridizing these algorithms for the task of fitting a multivariate Gaussian mixture model. This algorithm’s performance is contrasted with both the traditional approach and another hybrid algorithm on simulated and real data.
Electrical Bioimpedance as a Detection Tool for Internal Hemorrhaging and Blood Aggregation

description: Electrical bioimpedance was used to detect local volume and aggregation changes in blood. This was done with two separate experimentation processes to improve upon current research methods. Abdominal internal hemorrhaging is bleeding and pooling of blood within the abdominal cavity which can put the welfare of the patient at risk and may cause organ failure. Electrical bioimpedance is the response of biological tissue to applied electrical current. In cooperation with Bioparhom, electrical bioimpedance was used as a detection device for abdominal internal hemorrhaging. It is hypothesized that electrical bioimpedance could be a non-invasive and cost effective avenue for the detection of internal bleeding. In this study we investigate the use of electrical bioimpedance with a custom 8x8 needle electrode array, for detecting and locating the blood pooling due to a drop in resistivity in a rat using a Z-Metrix (function generator by Bioparhom). 5 and 95 kHz signals were inputted into a dead rat experiencing internal bleeding of porcine blood at a rate of 3.33 ml/min to 10 ml. For 8 rats, the 5 kHz frequency was found to be more sensitive to internal blood pooling. Red blood cell aggregation is a physiological process where red blood cells form reversible aggregates. RBC aggregation is an important indicator for physicians for the health of the circulatory system. Utilizing electrical bioimpedance, it is hypothesized that a reactance change as a result of blood aggregation will be detected. As well, a method is developed using impedance spectroscopy to determine s frequency which exhibits the highest reactance change during blood aggregation. This sensitive frequency, found to be 304 kHz, is compared to a frequency used by previous studies (100 kHz) to validate its. Using the Z-Metrix (function generator by Bioparhom) with a custom 4 electrode configuration, 2 ml of porcine blood mixed with 2 mg/ml of EDTA is tested for 2 minutes at a single frequency. The 304 kHz is found to be the most sensitive of the frequencies tested to reactance changes during aggregation. Results found for blood samples give an average AIc of 27.32 ± 11.44, which is within the physiological range for porcine blood of 3-30. It is seen that the 304 kHz has a higher precision than the 100 kHz frequency, but the AIc is within the same magnitude. As a result, 304 kHz is found to be a more favorable frequency than the previously published 100 kHz for the trials performed based on precision of the results and the sensitivity of the reactance change to blood aggregation.

description: We studied the effects of Ramadan intermittent fasting (RIF) on gut hormones (leptin, glucagon-like peptide-1 (GLP-1), peptide YY (PYY), cholecystokinin (CCK), and ghrelin) in males with obesity. Thirty sedentary males were randomly allocated to either an experimental group (EG, n = 15) or a control group (CG, n = 15). The EG group completed their Ramadan fasting rituals (30 days), whereas the CG continued with their normal daily habits. Blood samples were collected at four time points: 24 h before the start of Ramadan (T0), on the 15th day of Ramadan (T1), the day after the end of Ramadan (T2) and 21 days after Ramadan (T3). There were significant pre-to-post improvements for leptin (p = 0.01, d = 1.52), GLP-1 (p = 0.022, d = 0.75), PYY (p = 0.031, d = 0.69) and CCK (p = 0.027, d = 0.81) in the EG, with no interaction effect for ghrelin (p = 0.74; d = 0.008). No significant changes (p > 0.05) occurred in plasma volume variations (ΔPV) after RIF in both EG (−0.03 ± 0.01%) and CG (0.06 ± 0.07%). RIF represents an effective strategy to modify appetite-regulating hormones, leading to improved body composition indices and reduced obesity.
Loss of KATP Channel Activity in Mouse FDB Leads to an Impairment in Energy Metabolism During Fatigue

description: Recently, it has been postulated that fatigue is a mechanism to protect the muscle fiber from deleterious ATP depletion and cell death. The ATP-sensitive potassium (KATP) channel is believed to play a major role in this mechanism. Under metabolic stress, the channels open, reducing membrane excitability, Ca2+ release and force production. This alleviates energy demand within the fiber, as activation of the channel reduces ATP consumption from cellular ATPases. Loss of KATP channel activity during fatigue results in excessive intracellular Ca2+ ([Ca2+]i) levels, likely entering the fiber through L-type Ca2+ channels. It has been demonstrated that when mouse muscle lacking functional KATP channels are stimulated to fatigue, ATP levels become significantly lower than wild type levels. Thus, it was hypothesized that a lack of KATP channel activity impairs energy metabolism, resulting in insufficient ATP production. The focus of work for this M.Sc. project was to test this hypothesis. Fatigue was elicited in Kir6.2-/- FDB muscles for three min followed by 15 min recovery. After 60 sec, a 2.6-fold greater glycogen breakdown was observed in Kir6.2-/- FDB compared to wild type FDB. However, this effect disappeared thereafter, as there were no longer any differences between wild type and Kir6.2-/- FDB in glycogen breakdown by 180 sec. Glucose oxidation after 60 sec was also greater in Kir6.2-/- FDB compared to wild type FDB. However, levels of oxidation failed to increase in Kir6.2-/- FDB from 60 to 180 sec. Calculated ATP production during the fatigue period was 2.7-times greater in Kir6.2-/- FDB, yet measured ATP levels during fatigue are much lower in Kir6.2-/- FDB compared to wild type FDB. Taken together, it appears that muscle energy metabolism is impaired in the absence KATP channel activity.

description: The study of communication was born with the study of rhetoric, and scholars have been examining the creation and reception of messages for thousands of years. However, the term rhetoric often has negative connotations, as we hear people label some statement as “just rhetoric” or we hear them say, “The action doesn't match the rhetoric.” However, rhetoric is a style of communication that takes into account the effective use of both verbal and non-verbal languages, and it is one of the main ingredients in the day to day communication in organizations, healthcare organizations being no exception. It is virtually impossible to communicate without the use of rhetoric. This study focused on healthcare organizations because the delivery of healthcare is built on communication, and there is more to understand about the usage of language and organizational rhetoric in healthcare organizations. To these effects, the study examined communication in healthcare organizations and the perceived use of rhetoric among healthcare professionals; it explored how healthcare professionals perceive communication with their audiences, how the use of rhetoric, as perceived by healthcare professionals, affects communication in healthcare organizations and the contribution of rhetoric, as perceived by healthcare professionals, in motivating healthcare audience in healthcare organizations. The five canons of rhetoric were employed as a theoretical framework, and semi-structured interviews were used as tools for data collection. While contributing to existing literature on health and organizational communication, this study will also contribute in providing both government and private organizations insights into the use of rhetoric in professional communication with the hope of enhancing the quality of communication in the workplace.

 Composition. This taxon is downgraded here from family to subfamily rank. The subfamily includes two tribes, Diplocentrini and Nebini, and eight genera.
 Distribution. Asia (Middle East), North America, Caribbean, Central and South America.
 Taxonomic history. Interestingly, this taxon was originally established as a subfamily of Scorpionidae. Kraepelin (1905) elevated it to the family rank, and it was treated for almost 100 years as a family Diplocentridae (Sissom & Fet, 2000b). Prendini (2000) in a detailed phylogenetic analysis demonstrated its position as
a sister group to Scorpionidae (our subfamily Scorpioninae).
 Biogeographic history. The disjunct range of Diplocentrinae includes Middle East and New World. Lamoral (1980: 443) suggested that its origin could be Mesozoic (after fragmentation of Laurasia). It is hardly possible to explain this range by Gondwanaland fragmentation. The subsequent radiation of Diplocentrinae could be Cenozoic, both in tropics and, especially, in the arid zones of North America and the Middle East (burrowing forms of Nebo, Diplocentrus, and Bioculus).
 Diagnosis. See Prendini (2000) for details on the diagnosis of this subfamily (as family Diplocentridae).

submerged concrete

description: A harsh, cold, and icy environment is of no surprise to the conditions of a winter climate, where the wide use of de-icing salts on roads and highways allows for the initiation of chloride-induced corrosion of the reinforcement of concrete structures; a reduced service life, loss of structural integrity, visible damages, and ultimately structural failure are among the many unwanted effects of rebar corrosion. Chloride ingress into concrete has been extensively studied for the last four decades; however, most of the relevant research to date does not take into account the effects of sustained loading on chloride transport properties. Therefore, the objectives of this study were to investigate the influence of sustained compressive and tensile stresses on chloride ingress into concrete, and ultimately to understand what the effect of sustained stress is on chloride penetration depth, on chloride concentration by % weight of concrete, and on apparent diffusion coefficients by comparing results to those of unloaded control specimens. To achieve these objectives, six post-tensioned and four non-reinforced control concrete beams were constructed with different water-to-cement (w/c) ratios and completely submerged in a 4-5% de-icing salt (NaCl) solution for 12 weeks, allowing chloride transfer to be completely governed by continuous diffusion. The effects of supplementary cementing material on chloride ingress are also studied. Concrete beams were post-tensioned to induce variable sustained compressive and tensile stresses along the beam. After 12 weeks of exposure, beams were fractured at specific locations and sprayed with a 0.1N silver nitrate (AgNO3) solution to determine average penetration depths; chloride concentration profiles were obtained from potentiometric titration of grinded powder samples. Apparent chloride diffusion coefficients were then obtained from the results of spraying AgNO3 and titration, the latter by non-linear regression curve-fitting to Fick’s second law of diffusion. A good agreement between results from both methods reveals that the use of AgNO3 in field is acceptable in predicting the rate of chloride ingress in concrete sustaining stress. The chloride diffusivity for each profile, relative to that of the unstressed section, was related to the compressive and tensile stresses in the concrete section. The experimental results indicate the dependence of chloride ingress and concentration on the type and level of sustained stress. An analysis of the results to study the effects of the w/c ratio using colourimetric (silver nitrate spray) and potentiometric titration methods was also completed.

description: High resolution, multi-sensor, hot/cold-wire measurements were made in passively heated, uniformly sheared turbulence in a wind-tunnel. Measurements were focused on terms that are important for modelling of the scalar probability density function (PDF) equation. Unlike previous studies, which considered a single combination of velocity and scalar fields at a time, in this study three different scalar fields were investigated in the same nearly homogeneous turbulence with three passively superimposed temperature fields, namely a transversely homogeneous temperature field with a uniform mean gradient, and two inhomogeneous temperature fields, the plume of a heated line source and a thermal mixing layer. The use of the same uniformly sheared flow allowed the isolation of the effects of scalar inhomogeneity and initial conditions by evaluating the results in the three scalar fields. Thus, the measurements covered a wide range of scalar field conditions and set the ground for a conclusive comparison. For the homogeneous scalar field, results conformed with the literature: the scalar PDF was essentially Gaussian; the conditional expectations of velocities upon the scalar value were approximately linear; and the conditional expectation of the scalar dissipation rate upon the scalar value was mildly anisotropic and had a shape that was similar to those of any of its three parts, which justifies the use of the streamwise part as a surrogate for the total. All these properties behaved very differently in two inhomogeneous scalar fields, the thermal mixing layer and the plume of a heated line source: the scalar PDFs were distinctly sub-Gaussian; the conditional velocity expectations were non-linear functions of the scalar value; and the conditional scalar dissipation rates were very strongly anisotropic, as well as depending on the scalar value in fashions that differed strongly from those of any of their three parts.

description: A high share of renewables in the energy sector introduces volatility and forecast uncertainty on the generation side of the electricity system. These uncertainties are mitigated using storage systems. An example of such storage systems are residential photovoltaic battery systems that operate in an increasingly complex economic and regulatory environment. This thesis investigates model predictive control of such systems. Therein, external and historic data is used to model forecast uncertainty of household load as well as photovoltaic generation. This leads to stochastic optimal control problems which are solved using stochastic dynamic programming. With this approach, the nonlinear and discrete dynamics of the controlled system can be modeled without significant increase in computational requirements. The control scheme was applied to two cases in simulation and field test. In both cases the stochastic modelling yielded better performance than a comparable state of the art control scheme.

description: Contemporary theatre is increasingly visual, an aesthetic shift that has been analyzed in, among others, Hans-Thies Lehmann’s influential Postdramatic Theatre. This shift is apparent in Japanese director Tadashi Suzuki’s intercultural adaptations, which adapt plays of the Western repertoire for contemporary Japanese and international audiences in a style that is richly and evocatively visual. Notions drawn from postdramatic theatre, metatheatre and postcolonial theories are applied as framing devices to uncover the deep cultural and theatrical significance of Suzuki’s adaptive work. My approach to analyzing the three case studies: Suzuki’s King Lear, The Trojan Women, and Cyrano de Bergerac takes a more globalized view of theatrical adaptations that acknowledges the visual turn of contemporary theatre and contributes to the fields of intercultural performance studies and adaptation studies by expanding the notion of interculturalism beyond the limits imposed by current Western analytical perspectives.

description: Tribe Diplocentrini Karsch, 1880, new rank   Type Genus. Diplocentrus Peters, 1861.
 Composition. This tribe is established here, and corresponds to the former subfamily Diplocentrinae. It includes seven genera, with most species found in the New World.
 Distribution. Asia (Middle East), North America, Caribbean, Central and South America.
 Biogeographic history. The most diverse genus, Diplocentrus, includes numerous species in the deserts of North America, exhibiting an extensive arid radiation (analogous to that of Vaejovidae in North America, or Scorpioninae and Buthidae in Asia and Africa). Disjunct range of the genus Heteronebo between the Caribbean and Middle East is not yet clearly explained (Nenilin & Fet, 1992; Lourenço & Sissom, 2000; Sissom & Fet, 2000b). Santiago-Blay & Craig (1998) reported an Oligocene Heteronebo sp. from the amber of Dominican Republic.
 Diagnosis. See Prendini (2000) for details on the diagnosis of this tribe (as subfamily Diplocentrinae).

description: In the wind industry, optimizing the power output of the wind park (or single turbines) in different atmospheric conditions is the key factor to achieve better performance and therefore, energy yield. For that purpose there is a need to monitor the performance of wind turbines continuously by detecting the abnormal behavior of the wind turbines at different wind conditions. The use of machine learning in predicting the different wind conditions at different locations enables to reduce the measuring costs and maintenance costs. In this work, different machine learning models (linear regression, random forest, support vector regressor, and neural network) were implemented on different types of data (SCADA, met mast and weather model data) in order to predict the wind speeds at different locations in a wind park. The thesis project will focus on the best possible use of machine learning models in predicting the wind conditions in a wind park and on comparing the different model results.

description: PRIDE preservice training is a widely-used method of resource parent preparation, yet a program that has been the focus of very little research. This thesis project was carried out in two studies designed to examine the process of training, investigate selected outcomes of the training, and explore the transfer of training into practice. The first study involved 174 prospective resource parents. Investigation of the process of preservice training determined that participant engagement and participant-perceived fidelity, the combination of which was conceptualized as participant-perceived training quality, were high. In terms of outcomes, significant large gains from pre- to posttraining were observed in knowledge of the PRIDE competencies taught by the training. However, no differences were found in resource parent attitudes (erroneous beliefs or motivation to adopt) from pre- to posttraining. Higher training quality was a significant predictor of both greater knowledge gains and higher participant satisfaction. No differences between prospective foster parents and adoptive parents emerged in terms of participant dropout, knowledge gain, participant satisfaction, or attitudes about resource parenting. The second study was a follow-up with 11 foster, adoptive, and kinship parents from study one who had begun parenting a child in care. Interviews with these resource parents focused on the transfer of training of the PRIDE competencies and requested feedback about the training. Participants’ ratings of their transfer of training were high, while the researchers’ ratings fell in the mid-range. Overall, participants’ comments about PRIDE were positive. Participants highlighted how useful they found personal accounts of resource parents’ experiences during training and that child welfare workers played a key role in the implementation of training. The methodological contributions of this project include the development of three measures – a knowledge of PRIDE competencies questionnaire, a measure of participant-perceived quality, and a transfer of training rating scale – that can be used both in future research and in practice. In addition, this project supplied the first evidence of meaningful links between the process, outcomes, and transfer of PRIDE training, all of which were positive. The project provided essential foundational research which future studies of PRIDE should take into account.
