Dissertation Submitted in fulfilment of the requirements for a M Ed Degree in the School of Education Faculty of Humanities, University of the Witwatersrand, Johannesburg, 2016 / South African Sign Language (SASL) is officially recognised as a formal Home Language school subject within the National Curriculum Statement Policy of South Africa. However, this long awaited roll-out of the CAPS SASL raises a number of issues within the context of each school for the Deaf regarding implementation and school leadership. Hence, a case study was undertaken at a public school for the Deaf located within Johannesburg District to draw attention to these issues. Using Freire’s concepts of Dialogue, Conscientization and Praxis (Freire, 1972) as a means to bring about transformational changes within the school for the implementation year of SASL, 2015, the study explored the dialogue between School Management Team (SMT) and staff members who teach the Deaf learners. The models of school leadership investigated were: transactional, transformational and transformative leadership (Shields, 2010) as a framework for the changing roles as demonstrated by the SMT and the said staff members. Qualitative data provided insight into different strategies employed by them as well as class assistants to implement SASL; and further revealed the changes experienced within the school and by several staff members, where members were becoming more aware of their SASL abilities and how they would want to improve. Emergent themes included the ‘SASL curriculum’, ‘leadership and change’, ‘bilingual education and quality of education’ for Deaf learners. Change was evident between the positional authority of SMT members and the language authority of the Deaf staff members and revealed how this transformation in respect for different roles of the SMT assisted the SASL implementation. Findings revealed that SMT members and Deaf staff need to engage in extensive dialogue and implement strategies to facilitate the SASL implementation if there is to be meaningful transformation within the school / XL2018

Increasing evidence that ordinary cues paired with reward can acquire value indicates that the incentive properties of rewards are capable of being transferred onto cues, making them incentive stimuli. Studies have begun focusing on isolating components of the reward circuit involved in imparting incentive salience onto a cue with the goal of identifying rats with susceptibilities to drug addiction. Such studies have found that under a Pavlovian Conditioned Approach (PCA) paradigm, sign-tracking rats are at increased risk for instilling incentive salience onto conditioned stimuli and for engaging in drug-related behavior. With better understanding of the neural basis of sign tracking and its behavioral aspect of drug seeking comes a better chance of discovering treatment methods for drug addiction. This study examines the potential behavioral outcomes of altering the pathway starting in the Ventral Pallidum (VP) and ending in the Ventral Tegmental Area (VTA) by using Designer Receptors Exclusively Activated by Designer Drugs (DREADDs). While there is some evidence of an interaction between the effects of DREADDs on this neural circuit and behavior, not all results presented here reach significance. Additional studies are needed to confirm the hypothesis of specific inhibitory DREADDs from the VP to the VTA causing increased amounts of sign tracking in rats as a way to assess whether this pathway is implicated in predisposing rats to sign-tracking behavior. / 2018-07-11T00:00:00Z

Background: There are 850,000 people living with dementia in the UK; this number includes Deaf people who use British Sign Language, but little is known of their experience or how services might be improved to support them and their carers, who are often also Deaf. Deaf people are routinely excluded from reports on linguistic/cultural minorities and dementia because their status, as such, is not recognised. They are very different from the much larger population of older people who lose their hearing and may also have dementia. Aims and Objectives: i) To explore the everyday experiences of living with dementia from the perspectives of Deaf BSL users with dementia and their care partners; ii) To explore the general Deaf community's knowledge and understanding of dementia, its symptoms and impact on everyday life. Method: Three focus groups were held with a total of 26 Deaf BSL users, who did not have dementia, to gauge their knowledge about dementia and where they might go for support. Four Deaf BSL users living with dementia with five care partners took part in two semi-structured interviews 6-8 weeks apart. Data were analysed using thematic analysis, storied stories and narrative analysis. All data were collected in BSL by a Deaf researcher. ResultsLack of access to information and support in BSL impeded early recognition of symptoms, access to diagnosis, and support within the Deaf community. Personal narratives revealed Deaf people's resilience while living with dementia. Narratives challenged key concerns of personhood, citizenship and embodiment from a different perspective because Deaf people are not usually regarded as full citizens and their capacity is routinely challenged regardless of dementia. Furthermore, embodiment of communication and language is a life-long experience, not residual adaptation. Visual strategies to support agency were also documented. Conclusions: The Deaf community needs provision of accessible and understandable information about dementia in BSL. Mainstream dementia support services should review their accessibility of effective support for Deaf BSL users who have been diagnosed with dementia and their families. However, Deaf people with dementia remain resilient and positive about their everyday lives with the support of their familial relationships.

In reduced speed zones, where no other cues indicate the need to slow down, drivers sometimes fail to notice the standard Speed Limit sign and may be speeding inadvertently. To help reduce inadvertent speeding, a red border was installed around the Speed Limit sign in seven reduced speed areas and the impacts of the increased conspicuity on speed limit compliance were measured. The general study approach was to collect and compare speed data for a standard sign (before condition) and a red border sign (after condition). The short-term effects of a modified red border sign, which was achieved by replacing the thin black border of the standard sign with a four inch wide red border, were evaluated at four sites. Results of this modified border study indicated that there was a statistically significant reduction in the mean speeds as well as in the 85th percentile speeds for the red border sign conditions, however the reductions were not practically significant. This study also evaluated the effect of using a higher conspicuity sheeting material at two sites. The results indicated that use of higher conspicuity sheeting has some benefits for the standard sign but no additional benefits for the red border sign. The added border study evaluated the long-term effects (approximately nine to eleven months after the treatment) of adding a three inch wide red border to the standard Speed Limit sign at three sites. The results of this study indicated that impacts of the red border treatment increase with passage of time. The mean speeds decreased by 8.1 percent and the percent of vehicles exceeding the speed limit (55 mph) decreased by 21.7 percent. The decreases in speeds were both statistically and practically significant. A comparison of the thesis study with other similar studies found in literature shows comparable benefits of the red border sign with other speed management measures. Based on the results for long-term effects, use of the red border Speed Limit sign is recommended in reduced speed zones where inadvertent speeding is common.

This study analyzes the rhetorical strategies of an international public service organization. Drawing upon narrative criticism, volunteer related literatures of the Continental Societies, Inc. were studied in order to gauge their rhetorical efficacy in light of the existing literature on nonprofit organizations and volunteerism. By analyzing the organization’s literatures – their “story” – it was discovered that part of it was missing. In an attempt to fill this void, more effective materials related to volunteer recruitment and retention have been created to exemplify greater narrative fidelity, along with recommended organizational transformations that create a better fit between these “stories” and the truth of them.

Intelligent Transportation System (ITS) is a system that builds a safe, effective and integrated transportation environment based on advanced technologies. Road signs detection and recognition is an important part of ITS, which offer ways to collect the real time traffic data for processing at a central facility.This project is to implement a road sign recognition model based on AI and image analysis technologies, which applies a machine learning method, Support Vector Machines, to recognize road signs. We focus on recognizing seven categories of road sign shapes and five categories of speed limit signs. Two kinds of features, binary image and Zernike moments, are used for representing the data to the SVM for training and test. We compared and analyzed the performances of SVM recognition model using different features and different kernels. Moreover, the performances using different recognition models, SVM and Fuzzy ARTMAP, are observed.

Predicates KNOW, WANT, LIKE, HAVE, and GOOD have been reported to differ from other predicates in American Sign Language (ASL) in that they are typically negated by reversing the orientation of hand[s] in a twisting outward/downward movement. This phenomenon has been termed "negative incorporation." In this study, I examine semantic properties of negative-incorporation predicates. Specifically, I investigate whether these predicates also allow other negation strategies available in ASL and what the meanings conveyed by using these strategies are. I provide a detailed description of negative incorporation and demonstrate that it has a different status for the verbal predicates WANT, LIKE, and KNOW versus the adjectival predicate BAD. Using the data from a structured data collection procedure in the form of a production task and the elicitation of acceptability judgments, I identify various possibilities and preferred strategies for the investigated predicates, show that most signers do not accept negative incorporation with HAVE in contemporary ASL, demonstrate that nonmanual negation when a negative headshake is the only indicator of negation cannot be used with the verbal negative-incorporation predicates, and point out that there is variation among signers with respect to the preferred strategy of negation for LIKE that can be explained by historical change in progress. / text
