Resumen
The semantic system contributes to the process of speech production in two major ways. The basic information is contained within semantic representations, and the semantic control system manipulates that knowledge as required by task and context. This thesis explored the evidence for interactivity between semantic and phonological stages of speech production, and examined the role of semantic control within speech production. The data chapters focussed on patients with semantic aphasia or SA, who all have frontal and/or temporoparietal lesions and are thought to have a specific impairment of semantic control. In a novel development, grammatical class and cueing effects in this patient group were compared with healthy participants under tempo naming conditions, a paradigm which is thought to impair normal semantic control by imposing dual task conditions. A basic picture naming paradigm was used throughout, with the addition of different grammatical classes, correct and misleading phonemic cues, and repetition and semantic priming: all these manipulations could be expected to place differing loads on a semantic control system with either permanent or experimentally induced impairment. It was found that stimuli requiring less controlled processing such as high imageability objects, pictures with simultaneous correct cues or repetition primed pictures were named significantly more accurately than items which needed more controlled processing, such as low imageability actions, pictures with misleading phonemic cues and unprimed pictures. The cueing evidence offered support to interactive models of speech production where phonological activation is able to influence semantic selection. The impairment in tasks such as the inhibition of task-irrelevant material seen in SA patients and tempo participants, and the overlap between cortical areas cited in studies looking at both semantic and wider executive control mechanisms suggest that semantic control may be part of a more generalised executive system.

Resumen
Book Summary: With detailed discussion and invaluable video footage of 23 treatment interventions for speech sound disorders (SSDs) in children, this textbook and DVD set should be part of every speech-language pathologist's professional preparation. Focusing on children with functional or motor-based speech disorders from early childhood through the early elementary period, this textbook gives preservice SLPs critical analyses of a complete spectrum of evidence-based phonological and articulatory interventions. This textbook fully prepares SLPs for practice with a vivid inside look at intervention techniques in action through high-quality DVD clips large and varied collection of intervention approaches with widespread use across ages, severity levels, and populations proven interventions in three categories: direct speech production, broader contexts such as perceptual intervention, and speech movements clear explanations of the evidence behind the approaches so SLPs can evaluate them accurately contributions by well-known experts in SSDs from across the US, Canada, Australia, and the UK An essential core text for pre-service SLPs—and an important professional resource for practicing SLPs, early interventionists, and special educators—this book will help readers make the best intervention decisions for children with speech sound disorders. Evidence-based intervention approaches—demonstrated in DVD clips—such as: minimal pairs perceptual intervention core vocabulary stimulability treatment intervention for developmental dysarthria the psycholinguistic approach Interventions for Speech Sound Disorders in Children is a part of the Communication and Language Intervention Series

Stelle, Elizabeth Leigh. "Visual feedback during speech production". Thesis, University of British Columbia, 2016. http://hdl.handle.net/2429/60236.

Texto completo
Resumen
The visual speech signal has a well-established influence on speech perception, and there is growing consensus that visual speech also influences speech production. However, relatively little is known about the response to one's own visual speech; that is, when it is presented as speech feedback. Since visual feedback is generated by the same speaking event that generates auditory and somatosensory feedback, it is temporally compatible with these typical sources of feedback; as such, it is predicted to influence speech production in comparable ways. This dissertation uses a perturbation paradigm to test the effect visual feedback has on production. Two delayed auditory feedback experiments tested the effect of different types of visual feedback on two fluency measures: utterance duration and number of speech errors. Visual feedback was predicted to enhance fluency. When the presentation of static and dynamic visual feedback was randomized within a block, utterance duration increased with dynamic visual feedback but there was no change in speech errors. Speech errors were reduced, however, when the different types of visual feedback were presented in separate blocks. This reduction was only observed when dynamic visual feedback was paired with normal auditory feedback, and for those participants who were more verbally proficient. These results suggest that consistent exposure to visual feedback may be necessary for speech enhancement, and also that the time-varying properties of visual speech are important in eliciting changes in speech production. In the bite block experiment, participants produced monosyllabic words in conditions that differed in terms of the presence or absence of visual feedback and a bite block. Acoustic vowel contrast was enhanced and acoustic vowel dispersion was reduced with visual feedback. This effect was strongest at the beginning of the vowel and tended to be stronger during productions without the bite block. For a small subset of participants the magnitude of motion of the lower face increased in response to visual feedback, once again without the bite block. The results of this dissertation provide evidence that visual feedback can enhance speech production, and highlight the multimodal nature of speech processing.

Resumen
Although audition may appear to be the dominant sensory modality in speech production, the capacity for intelligible speech following severe hearing loss suggests that other sensory information - for example, somatosensory feedback - may also contribute to the achievement of speech targets. The aim of this thesis is to explore the role of somatosensory feedback in speech produced by healthy adults.
The first study aimed at providing a test of whether somatosensory feedback plays a role in speech production beyond the language acquisition period in early childhood. In order to achieve this goal, we designed a pattern of forces that affects jaw movements during speech production, but at the same time has no measurable acoustic effect. We found that subjects compensated for such a distortion in speech movement trajectories, even though it had no impact on the sounds. In contrast, no adaptation was observed in matched non-speech jaw movements, indicating that this was not an inevitable consequence of exposing the orofacial apparatus to this pattern of forces. This is the first demonstration that somatosensory information on its own drives the achievement of articulator positions in speech.
In study one, it was observed that subjects only adapted to the loads in the opening phase of the jaw movement. In order to elucidate this somewhat unexpected finding, we carried out experiments in which we manipulated the linguistic content of the training utterance. We found that subjects compensated for the perturbations only in portions of the movement that contained a vowel-to-vowel transition. It was suggested that the required kinematic precision during a transition between two vocal tract shapes associated with vowels is higher than during transitions between a consonant and a vowel. It also points to the speech-like nature of the observed adaptation.
The third study aimed at investigating the extent to which speech motor learning generalizes across acoustic contexts. We trained subjects to produce utterances while exposed to a velocity dependent force field. After learning, the subjects were tested with new utterances, matched on dynamics to the ones used in training. Note that even if the acoustic contents of the test and the training utterances were different, the loads had a similar effect on both speech movements. We showed that learning did not transfer to the test utterances; therefore adaptation was restricted to the specific training context. These results point to the specificity of speech motor learning.

Resumen
The article conducts an analysis of the content of regional Public Television during the full-scale Russian-Ukrainian war. A comparative analysis of programs created by regional teams of the Public broadcaster before the full-scale invasion is presented. The research aims to study and provide a detailed analysis of the television content of regional branches of Public Television to understand the peculiarities of operation during a state of war, track changes in the thematic content, and speech format. Analytical methods of scientific research (analysis of television content of regional branches of Public Television), as well as inductive, deductive, and abstract-logical methods, are employed. The historical method is applied to the study of television reform in Ukraine. The key method in the research is content analysis, which is used to study the impact of television reform on the quality and volume of content of regional branches of Public Television. Using the example of the content of “Suspilne-Ternopil,” the thematic and problematic content of programs of the regional branch of Public Television is investigated. A significant reduction in the share of in-house produced content on local issues is identified. In particular, at the beginning of the full-scale invasion, the production of the program “Today. Main” was suspended, a socio-political talk show that extensively covered local issues. Emphasis is placed on the importance of regional media in times of war, representing the interests of the public at both regional and central levels. In our opinion, regional broadcasters of Public Television should reintroduce in-house produced programs to restore a platform for discussing local issues. Strengthening ties with high-quality media from neighboring states is also advisable, specifically for the exchange of journalists’ experiences and high-quality content. Keywords: Public television, television reform, Russian-Ukrainian war, television content, broadcast, regional branch.

Resumen
Extending the previous two years of research results (Mizarch, et al, 2012, Tao, 2011, 2012), the third year’s efforts in both Maryland and Israel were directed towards the engineering of the system. The activities included the robust chick handling and its conveyor system development, optical system improvement, online dynamic motion imaging of chicks, multi-image sequence optimal feather extraction and detection, and pattern recognition. Mechanical System Engineering The third model of the mechanical chick handling system with high-speed imaging system was built as shown in Fig. 1. This system has the improved chick holding cups and motion mechanisms that enable chicks to open wings through the view section. The mechanical system has achieved the speed of 4 chicks per second which exceeds the design specs of 3 chicks per second. In the center of the conveyor, a high-speed camera with UV sensitive optical system, shown in Fig.2, was installed that captures chick images at multiple frames (45 images and system selectable) when the chick passing through the view area. Through intensive discussions and efforts, the PIs of Maryland and ARO have created the protocol of joint hardware and software that uses sequential images of chick in its fall motion to capture opening wings and extract the optimal opening positions. This approached enables the reliable feather feature extraction in dynamic motion and pattern recognition. Improving of Chick Wing Deployment The mechanical system for chick conveying and especially the section that cause chicks to deploy their wings wide open under the fast video camera and the UV light was investigated along the third study year. As a natural behavior, chicks tend to deploy their wings as a mean of balancing their body when a sudden change in the vertical movement was applied. In the latest two years, this was achieved by causing the chicks to move in a free fall, in the earth gravity (g) along short vertical distance. The chicks have always tended to deploy their wing but not always in wide horizontal open situation. Such position is requested in order to get successful image under the video camera. Besides, the cells with checks bumped suddenly at the end of the free falling path. That caused the chicks legs to collapse inside the cells and the image of wing become bluer. For improving the movement and preventing the chick legs from collapsing, a slowing down mechanism was design and tested. This was done by installing of plastic block, that was printed in a predesign variable slope (Fig. 3) at the end of the path of falling cells (Fig.4). The cells are moving down in variable velocity according the block slope and achieve zero velocity at the end of the path. The slop was design in a way that the deacceleration become 0.8g instead the free fall gravity (g) without presence of the block. The tests showed better deployment and wider chick's wing opening as well as better balance along the movement. Design of additional sizes of block slops is under investigation. Slops that create accelerations of 0.7g, 0.9g, and variable accelerations are designed for improving movement path and images.

Resumen
The article aims to analyze the structural changes and the Ukrainian labor market organization in the condition of military aggression against Ukraine. The Ukrainian economy encounters the devastating destructions and losses of economic entities, enormous capital, and labor under the effect of military aggression. Structural changes include a change in the industrial structure of production, the destruction of large enterprises, and supply chains, the loss of part of the labor force, and fluctuations between skilled and unskilled jobs. Thus, SMEs in the service sector suffer due to the reduction of the population in cities, which causes both a reduction in demand for certain types of services (hotel and restaurant business, beauty salons, providers of extracurricular educational services, etc.) and a reduction in the supply of highly qualified specialists (IT sector, experts in financial, design and consulting services). Small business because of the war feels caught between the minimum possible sale of their products and reduced demand. The basic research questions are identifying and estimating the urgent needs of the labor market and capital. It will be directed to define sectors that can speed up the process of rebuilding the economy. Diversifying the economy, increasing product/service sophistication, using comparative advantages and transfer of resources (both labor and capital) leads to more productive activities and a rise in well-being.

Resumen
Laser beam welding (LBW) has become standard in many high-production and critical applications where the return on investment can be quickly realized due to the process' inherent efficiency in terms of weld penetration and travel speed. Also, some promising work has been done internationally related to the use of hybrid laser/arc welding (HLAW) for some applications (primarily shipbuilding), so this process variation was also included in the study. However, virtually all of the current LBW or HLAW applications are considered 'factory' applications, and therefore do not represent the logistical challenge associated with bringing laser technology to on or offshore pipeline welding operations. This project was aimed at studying the feasibility of overcoming those logistical challenges in order to realize the potential cost savings of applying this high production process. This study was limited to the application of Nd:YAG lasers (which can be delivered via fiber-optic cable) since the logistics of incorporating higher power CO2 lasers was felt to be impractical. The focus of the project was to study the potential productivity of the LBW and HLAW processes in terms of the thickness of material that could be welded in a single pass at a given travel speed. Additionally, the robustness of the process was determined using weld joints with less than ideal fit up. Potential feasibility of the processes were then determined by considering both the practical aspects of their application as well as the economic justification.

Resumen
This study looks at fishing activity in the Philippines’ Exclusive Economic Zone in 2012, as well as how it responded to tropical cyclones. The study identifies the main fishing grounds and examines the impact of tropical cyclone speed on vessel position using satellite images and tropical cyclones data. Data suggest that tropical cyclones have a negative impact on fishing activity, with fewer active boats during and after the storm. The most affected locations include the Sibuyan Sea, Visayan Sea, and Panay Gulf. These tropical cyclones were estimated to reduce commercial fishing production by 7,800 tons per day, affecting more than 188,000 families in Western Visayas.

Resumen
Dust aerosols can pose a significant detriment to public health, transportation, and tactical operations through reductions in air quality and visibility. Thus, accurate model forecasts of dust emission and transport are essential to decision makers. While a large number of studies have advanced the understanding and predictability of dust storms, the majority of existing literature considers dust production and forcing conditions of the underlying meteorology independently of each other. Our study works to-wards filling this research gap by inventorying dust-event case studies forced by convective activity in the Desert Southwest United States, simulating select representative case studies using several configurations of the Weather Research and Forecasting (WRF) model, testing the sensitivity of forecasts to essential model parameters, and assessing overall forecast skill using variables essential to dust production and transport. We found our control configuration captured the initiation, evolution, and storm structure of a variety of convective features admirably well. Peak wind speeds were well represented, but we found that simulated events arrived up to 2 hours earlier or later than observed. Our results show that convective storms are highly sensitive to initialization time and initial conditions that can preemptively dry the atmosphere and suppress the growth of convective storms.

Resumen
An executed NDA is required from Solar Turbines to have access to this document. The low load control algorithm for Solar Turbines' Taurus 70-10802S and Titan 130-20502S has been modified and evaluated in two field trials at the Kinder Morgan Wharton 301 and Enbridge Sabal Trail Alexander City Compressor Stations. The new algorithm extends temperature control, via bleed valve modulation, to lower engine speed settings now covering operation from full load to idle vs full load to 50% load with the prior production control method. The pilot fuel control schedule has also been optimized along with the temperature control schedule. The new control algorithm is designated as Enhanced Emissions Control (EEC). A Mobile Emissions Lab was deployed for the Taurus 70S site and for the Titan 130S site. The field trials spanned 12 months for the Taurus 70S and 8 months for the Titan 130S. Data was collected over a wide range of temperatures.
