Conventional hearing aid circuitry is often unable to provide children with hearing loss with sufficient high frequency information in order to develop adequate oral language skills due to the risk of acoustic feedback and the narrower frequency spectrum of conventional amplification. The purpose of this study was to investigate word recognition abilities of children with moderate-to-severe hearing loss using hearing aids with linear frequency transposition. Seven children with moderate-to-severe sensorineural hearing loss between the ages of 5 years 0 months and 7 years 11 months were selected for the participant group. Word recognition assessments were first performed with the participants using their own previous generation digital signal processing hearing aids. Twenty-five-word lists from the Word Intelligibility by Picture Identification (WIPI) test were presented to the participants in three test conditions, namely: at 55 dB HL in quiet, 55 dB HL with a +5 dB signal-to-noise ratio (SNR) and at 35 dB HL. The participants were then fitted with an ISP-based hearing aid without linear frequency transposition, and the word recognition assessments were repeated with different WIPI word lists under the same conditions as the first assessment. Linear frequency transposition was then activated in the ISP-based hearing aid and different WIPI word lists were presented once more under identical conditions as the previous assessments. A 12-day acclimatization period was allowed between assessments, and all fittings were verified according to the DSL v5 fitting algorithm. Results indicated a significant increase of more than 12% in word recognition score for some of the participants when they used the ISP-based hearing aid with linear frequency transposition. A significant decrease was also seen for some of the participants when they used the ISP-based hearing aid with linear frequency transposition, but all participants presented with better word recognition scores when they used the ISP-based hearing aids without linear frequency transposition compared to their previous generation digital signal processing hearing aids. This study has shown that linear frequency transposition may improve the word recognition skills of some children with moderate-to-severe sensorineural hearing loss, and more research is needed to explore the criteria that can be used to determine candidacy for linear frequency transposition. / Dissertation (MCommunication Pathology)--University of Pretoria, 2010. / Speech-Language Pathology and Audiology / Unrestricted

In music education, aesthetic education and praxial music education serve as two major, guiding philosophical frameworks, yet supporters of each often conflict with one another. Furthermore, both are slightly problematic with respect to the specific context of the public school. Each framework is primarily music-based, however, music education has existed in the wider context of general education since the 1830s. Given the recent core-status designation for music education, as part of all fine arts, in the reauthorization of the Elementary and Secondary Education Act, a framework from general education that supported music education could offer benefits for the domain. However, the wider context of general education is messy as well. Two groups occupy most of the space there, and remain locked in a fundamental disagreement over the purpose of a formal education. The progressive educators, historically framed by Dewey and Thorndike, contend that education functions as societal improvement. In contrast, the essentialists contend that education functions as cultural transmission. Therefore, a more specific need for music education involves selecting a framework from general education that resolves this conflict. The writings of William Chandler Bagley indicate that he balanced both considerations of a formal education while also advancing his notion of essentialism. Bagley differed from the progressive educators predominately associated with Dewey over definitions and ideas surrounding a democratic education. Emergent points of contrast with Thorndike include distinctions between social efficiency and Bagley's alternative idea of social progress. Bagley also diverged from other essentialists over definitions concerning liberal and cultural education. To make these viewpoints of Bagley explicit, I describe characteristics of a progressive education, and an essentialist education separately, before introducing Bagley. Finally, I apply Bagley's ideas into the domain of music education. Ultimately, I contend that through common outcomes of creativity, competition, and literacy, the domain of music education can remain securely grounded in the values within the public schools.

Background: Pimecrolimus cream 1% is a non-steroid, selective inflammatory cytokine inhibitor indicated for atopic dermatitis (AD). Objective: To compare the safety and efficacy of pimecrolimus cream 1%-based treatment versus conventional therapy in adults with moderate AD. Methods: Patients were randomized to receive pimecrolimus cream 1% (n = 62) or vehicle (n = 68) at the first signs/symptoms of AD, for 24 weeks as required. A moderately potent topical corticosteroid (prednicarbate 0.25% cream) was allowed in both groups to treat flares. Results: Corticosteroids were required on fewer days in the pimecrolimus group, compared with the vehicle group (9.7 vs. 37.8%, p < 0.001). Furthermore, 59.7% of pimecrolimus-treated patients experienced no flares during the study period, compared with 22.1% of vehicle-treated patients (p < 0.001). Pimecrolimus cream 1% was well tolerated throughout the study. Conclusion: For adults with moderate AD, pimecrolimus cream 1% is well tolerated, reduces the incidence of flares, reduces/eliminates corticosteroid use, improves long-term disease control and enhances the patients’ quality of life. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

The Parliament of Catalonia was restored in 1980 within the transition to democracy in Spain. From the beginning the coalition of Convergència i Unió was dominated in party system. This coalition was consisted by two parties and had absolute parliamentarian majority between years 1984 and 1995. Its dominance was disrupted by Partit dels Socialistes de Catalunya in elections in 1999 and also in 2003. Until then, there was a bipolar system where CiU won elections to the Parliament of Catalonia and PSC-PSOE elections to Congreso de Diputados in this autonomous region. CiU won every Catalan parliamentary elections till 2012. After the collapse of CiU in 2015, one of its parties, Convergència Democràtica de Catalunya, started to cooperate with Esquerra Republicana de Catalunya primarily because of Catalonia's independence. The number of relevant parties started to increase in 2015. The aim of the thesis is to answer following questions: what party system according to Sartori's theory occurred/occurs in the Parliament of Catalonia and whether there was a change of party system or not. If yes, then which circumstances affected this change. Furthermore, the results of the elections to the Parliament of Catalonia and to Congreso de Diputados in Catalonia are compared. This comparison seeks to answer the question of...

Satellites provide humanity with data to infer properties of the earth that were impossible a century ago. Humanity can now easily monitor the amount of ice found on the polar caps, the size of forests and deserts, the earth’s atmosphere, the seasonal variation on land and in the oceans and the surface temperature of the earth. In this thesis, new hypertemporal techniques are proposed for the settlement detection problem in South Africa. The hypertemporal techniques are applied to study areas in the Gauteng and Limpopo provinces of South Africa. To be more specific, new sequential (windowless) and non-sequential hypertemporal techniques are implemented. The time-series employed by the new hypertemporal techniques are obtained from the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor, which is on board the earth observations satellites Aqua and Terra. One MODIS dataset is constructed for each province. A Support Vector Machine (SVM) [1] that uses a novel noise-harmonic feature set is implemented to detect existing human settlements. The noise-harmonic feature set is a non-sequential hypertemporal feature set and is constructed by using the Coloured Simple Harmonic Oscillator (CSHO) [2]. The CSHO consists of a Simple Harmonic Oscillator (SHO) [3], which is superimposed on the Ornstein-Uhlenbeck process [4]. The noise-harmonic feature set is an extension of the classic harmonic feature set [5]. The classic harmonic feature set consists of a mean and a seasonal component. For the case studies in this thesis, it is observed that the noise-harmonic feature set not only extends the harmonic feature set, but also improves on its classification capability. The Cumulative Sum (CUSUM) algorithm was developed by Page in 1954 [6]. In its original form it is a sequential (windowless) hypertemporal change detection technique. Windowed versions of the algorithm have been applied in a remote sensing context. In this thesis CUSUM is used in its original form to detect settlement expansion in South Africa and is benchmarked against the classic band differencing change detection approach of Lunetta et al., which was developed in 2006 [7]. In the case of the Gauteng study area, the CUSUM algorithm outperformed the band differencing technique. The exact opposite behaviour was seen in the case of the Limpopo dataset. Sequential hypertemporal techniques are data-intensive and an inductive MODIS simulator was therefore also developed (to augment datasets). The proposed simulator is also based on the CSHO. Two case studies showed that the proposed inductive simulator accurately replicates the temporal dynamics and spectral dependencies found in MODIS data. / Thesis (PhD(Eng))--University of Pretoria, 2012. / Electrical, Electronic and Computer Engineering / unrestricted

This diploma thesis is focused on leisure activities for children with moderate and severe mental retardation. The theoretical framework demonstrates the degrees of mental retardation, and in addition, integration and inclusion issues in education are discussed. This part of the diploma thesis acquaints with potential leisure centres and presents various forms of leisure activities for children with moderate and severe mental retardation. The practical application part identifies specific leisure activity options and in a collaboration with leisure centres it provides a comprehensive overview of leisure activities for children with moderate and severe mental retardation in Kolin and Nymburk region. It also captures parental interest in these leisure activities.

Background: Regular physical activity (PA) is critical for children’s health and wellbeing. Despite the numerous health benefits, most Canadian children do not meet the Canadian PA guidelines. The emergence of the COVID-19 pandemic and social restrictions added new challenges to meeting the PA guidelines. Mobile health (mHealth) technology can be leveraged to promote PA among children. Combining gamification with mHealth interventions has the potential to further improve program effectiveness. Thus, “Draco” was developed as a virtual pet smartphone app to increase PA in children using self-determination theory as a framework to promote intrinsic motivation for PA. Objective: The primary objective is to evaluate the satisfaction and acceptability of the Draco app after four weeks. Secondary objectives include evaluating the preliminary effectiveness of the Draco app to improve average daily steps, average daily MVPA, perceived autonomy for PA, perceived competence for PA, and perceived relatedness to the app. Methods: 43 Canadian children, aged 8-14 years old, not meeting the Canadian PA guidelines of 60min of MVPA per day were randomly allocated to an intervention or control group. Participants in the control group used a step-tracking app for four weeks. Intervention participants were instructed to use the Draco app. Participants completed a baseline and follow-up questionnaire. PA outcomes were tracked using a Fitbit provided to each participant. Intrinsic PA motivation was assessed using an adapted version of the Intrinsic Motivation Inventory (IMI). Intrinsic motivation was assessed using the satisfaction subscale. Exit interviews were completed to determine app acceptability. Results: Participants demonstrated high levels of satisfaction and acceptability with the Draco app 2.83 (1.29). Intervention participants increased their average daily steps by 909 (1701). The control group increased their steps by 46 (1507). The Draco app had a small effect on promoting steps, MVPA, relatedness and small effects at increasing autonomy and competence. Conclusion: Participants demonstrated high levels of satisfaction and acceptability with the app. Participants in the intervention group showed greater increases in PA with small effect sizes. Preliminary evidence highlights the importance of tailoring game design to the users. Technical limitations impacted recruitment and user experiences. Additional development time should be taken to stabilize the app and add new game features for a definitive RCT. / Graduate

>Magister Scientiae - MSc / The Cape Floristic Region (CFR) in South Africa, is one of the world's five Mediterranean hotspots, and is also one of the 34 global biodiversity hotspots. It has rich biological diversity, high level of species endemism in flora and fauna and an unusual high level of human induced threats. The Sandveld forms part of the CFR and is also highly threatened by intensive agriculture (potato, rooibos and wheat farming), proliferation of tourism facilities, coastal development, and alien invasions. These biodiversity threats have led to habitat loss and are threatening the long-term security of surface and ground water resources. In order to understand trends in such biodiversity loss and improve in the management of these ecosystems, earth-orbiting observation satellite data were used. This research assessed landuse changes and trends in vegetation cover in the Sandveld, using remote sensing images. Landsat TM satellite images of 1990, 2004 and 2007 were classified using the maximum likelihood classifier into seven landuse classes, namely water, agriculture, fire patches, natural vegetation, wetlands, disturbed veld, and open sands. Change detection using remote sensing algorithms and landscape metrics was performed on these multi-temporal landuse maps using the Land Change ModelIer and Patch Analyst respectively. Markov stochastic modelling techniques were used to predict future scenarios in landuse change based on the classified images and their transitional probabilities. MODIS NDVI multi-temporal datasets with a 16day temporal resolution were used to assess seasonal and annual trends in vegetation cover using time series analysis (PCA and time profiling).Results indicated that natural vegetation decreased from 46% to 31% of the total landscape between 1990 and 2007 and these biodiversity losses were attributed to an increasing agriculture footprint. Predicted future scenario based on transitional probabilities revealed a continual loss in natural habitat and increase in the agricultural footprint. Time series analysis results (principal components and temporal profiles) suggested that the landscape has a high degree of overall dynamic change with pronounced inter and intra-annual changes and there was an overall increase in greenness associated with increase in agricultural activity. The study concluded that without future conservation interventions natural habitats would continue to disappear, a condition that will impact heavily on biodiversity and significant water dependent ecosystems such as wetlands. This has significant implications for the long-term provision of water from ground water reserves and for the overall sustainability of current agricultural practices.
