abstract: Concert band classes have been part of the schooling landscape in Canada and the United States since the early 1900’s. Nevertheless, the context in which concert band classes have been offered recently has undergone a dramatic change. Typically, concert band classes have been offered as an elective course in schools, but more recently, concert band classes in some school settings have been required, especially at the beginning level. Because of the required band class context, it can no longer be assumed students in such band classes have the same music making goals exhibited by earlier generations of students. Persistence, resilience, engagement and musical self-efficacy have been affected when choice was no longer afforded. This study was conducted to examine how goal setting strategies influenced student persistence, resilience, engagement, and musical self-efficacy within a required beginning concert band class. Framed by Bandura’s Self-Efficacy Theory, Bronfenbrenner’s Ecological Systems Theory, and Tinto’s research on persistence, a goal setting intervention was devised and offered to students taking a required grade 6 beginning band classes at an independent school in Ontario. Using a concurrent mixed method framework, quantitative and qualitative data were collected. Results from the quantitative data indicated no changes in the outcome measures. By comparison, qualitative data indicated persistence, resilience, engagement, and musical self-efficacy were influenced when using the goal setting tools. From students’ perspectives, musical self-efficacy and personal self-efficacy were realized through grade attainment, music notation fluency, rhythmic accuracy goals established on students’ weekly goal charts, and goal setting mind maps. Persistence and resilience were influenced as students overcame physical challenges through scaffolding their practice efforts by creating individualized practice regimens. Engagement was influenced through the goal setting intervention as students set goals such as performing for others—be it peers, family, or their teachers. In terms of future research and practice, cycles of action research would include expanding the goal setting intervention to include creating differentiated music making experiences alongside the traditional concert band genre, based upon principles drawn from a community music making contexts—specifically those involving collaborative music making like those experienced in Samba band ensembles. Recommendations for such experiences were shared. / Dissertation/Thesis / Doctoral Dissertation Leadership and Innovation 2019

This study sets out to examine the factors driving consumption-based emission on the political agenda of Umeå municipality in northern Sweden. The paper attempts to contribute to the understanding of how climate change related issues can be given a more salient role on the political agenda of municipalities. Building on agenda-setting theories and previous studies on the subject of urban climate governance, a hypothesis was formulated to test existing theories and previous findings. Semi-structured interviews with elected politicians and municipal officials were used to gather empirics, to be analyzed and tested against the hypothesis. The main findings point towards the importance of engaged officials/politicians in bringing an issue to the municipal agenda and a supportive political context, created by policy tradition and history. Political trends and movements and external expertise were important factors in facilitating the implementation of the project encompassing consumption-based emissions on the municipal level, possibly fostering the emergence of it on the political agenda. No clear factor was found to be accountable for the transition of the issue from the municipal to the political agenda, being a product of multiple variables.

Decentralised detection and monitoring of hearing loss can be supported by new mHealth technologies using automated testing, which can be facilitated by minimally trained persons. These technologies may prove particularly useful in an infectious disease (ID) clinic setting where patients are at high risk for hearing loss. The current study aimed to evaluate the clinical utility of mobile and automated audiometry hearing health technology in an ID clinic setting. The current study was exploratory as it aimed to determine whether smartphone automated audiometry and South African English Digits-In-Noise (SA Eng DIN) smartphone applications could be utilised in an infectious disease clinic setting to monitor an HIV-related hearing loss in a feasible and time efficient way. Smartphone automated audiometry (hearTest™) and speech-in-noise testing (SA English Digits-In-Noise (DIN) test) were compared with manual audiometry at 2, 4, and 8 kHz. Smartphone automated audiometry and the DIN test were repeated to determine the test re-test reliability. Two hundred subjects (73% female and 27% male) were enrolled. Fifty participants were re-tested with the smartphone applications. Participants’ ages ranged from 18 to 55 years with a mean age of 44.4 (8.7 SD). Threshold comparisons were made between smartphone audiometry testing and manual audiometry. Smartphone automated audiometry, manual audiometry, and test re-test measures were compared to determine the statistical significance of any differences observed using the Wilcoxon signed-ranked test. Spearman rank correlation test was used to determine the relationship between the smartphone applications and manual audiometry, as well as for test re-test measurements. For all participants, 88.2% of thresholds corresponded within 10 dB or less between smartphone audiometry and manual audiometry. There was a significant difference (p>0.05) between smartphone and manual audiometry for the right ear at 4 and 8 kHz and the left ear at 2 and 4 kHz respectively. No significant difference was noted (p>0.05) between test and re-test measures of smartphone technology except at 4kHz in the right ear in smartphone automated audiometry. The absolute average difference between the initial and re-test of DIN testing was 1.2 dB (1.5 SD). No significant difference was noted in the test re-test measures of the DIN test (p < vii 0.05). A correlation coefficient of 0.56 was present in the DIN test re-test measures when the Spearman rank correlation test was administered. Smartphone audiometry with calibrated headphones provides reliable results and can be used as a baseline and monitoring tool at ID clinics. / Dissertation (MA)--University of Pretoria, 2017. / Speech-Language Pathology and Audiology / MA / Unrestricted

Parents and educators are often the first to notice that a learner is not coping in the school setting and is displaying certain disruptive behavioural aspects associated with a diagnosis of ADHD. For many parents this behaviour and resulting diagnosis of ADHD comes as a shock and they do not understand where it originates from, how it manifests within each individual or how to manage these symptoms successfully. Attention Deficit Hyperactivity Disorder (ADHD) is a chronic, neurodevelopmental disorder with no cure that can be identified according to the criteria laid out in the DSM-V (2013). Although no longer diagnosed as a learning disorder per se, ADHD is associated with several co-morbid conditions such as learning disabilities and psychological conditions that have a negative effect on learning (DSM-V, 2013:59). The goal of this study was to explore and describe the effect of Gestalt group work on the behavioural aspects associated with ADHD among adolescents in a school setting. Gestalt play therapy and in particular Gestalt group work, was employed in order to assist the adolescent diagnosed with ADHD in managing these disruptive behaviours. The research was conducted with adolescents in a secondary school in Gauteng. These adolescents were diagnosed with ADHD and were often singled out as being disruptive within the classroom. The population for this study was adolescents between the ages of 13 and 17 years, previously diagnosed with ADHD, who formed part of a specific school community. The researcher made use of non-probability sampling; specifically purposive and volunteer sampling. Seven adolescents were selected to take part in the quantitative research study, over a period of eight sessions (Strydom & Delport, 2011:392). The study was exploratory in nature and the type of research was applied research. The research design that was appropriate was the single-system design, seeing that this design enhances the link between research and practice (Strydom, 2011a:160). A standardised check list, the 'Current ADHD symptoms scale self-report' was used to obtain information by means of a pretest, mid-point and posttest measurement. This is a standardised measuring instrument that has been developed and tested through empirical methods of instrument development (Adler, Spencer, Faraone, Kessler, Howes, Biederman & Secnik, 2006). The data collected for this study was analysed statistically, through the univariate method of analysis. Computerised worksheets in Excel enabled the researcher to structure findings and to make the most valid and objective recommendations through organised interpretation of data collected (Fouchè & Bartley, 2011). Findings were presented graphically and illustrated in figures. All relevant ethical considerations were considered, for example participants provided informed assent, while their parents provided informed consent for the research to be conducted. Gestalt play provided for theme-based group sessions, assisting participants in recognising as well as mastering positive behaviour, as an alternative to the disruptive behavioural aspect of this condition. The research provided useful research data with regards to the use of both group work and Gestalt play techniques in assisting the adolescent with ADHD in addressing their disruptive behaviour. Gestalt group work as method of intervention seemed to have a positive effect on disruptive behaviour related to ADHD. The group as a whole had improved their behaviour for both the characteristics of ADHD. Behavioural aspects characterised by inattention, as well as hyperactivity and impulsivity for the group of respondents, had improved through the application of Gestalt play techniques. The group of respondents therefore perceived that they had benefited in terms of the improvement of these behavioural aspects of ADHD. It is recommended that educators, parents and caregivers be trained regarding ADHD in order to comprehend the nature of this disorder and the impact thereof on the learner and fellow learners in the classroom. Learners should become aware of their diagnosis, the symptoms and the disruptive element of their behaviour, the impact that this behaviour has in the classroom, as well as the resources available for the adolescent in addressing challenges. / Mini Dissertation (MSW)--University of Pretoria, 2017. / Social Work and Criminology / MSW / Unrestricted

Reconstruction of volcanic processes in the Komárov Complex: case from the Zaječov volcanic centre Summary Sheet lava flows with pillow breccias and hyaloclastites are interbedded agglomerate and volcaniclastics. This is the basic interpretation of rocks exposed in quarry near the town Zaječov. Rocks are part of geological area called Barrandien. Resediment volcaniclastic particles were transfer by sediment gravity flows. Agglomerates were deposited from volcaniclastic debris flow and fine grain volcanoclastics sediments from turbidity currents or hyperconcentrated flows. These types of flows named as eruption-fed aqueous density current are directly initiated by subaqueous volcanic eruption. One volcaniclastics strata set on the south wall of quarry was formed from subaquatic eruption plume, called steam copula. Steam copula created under the eruptive vent is water exclusion zone. Accretion lapilli can be formed in this zone if the copula is stable for a longer time. Accretion lapilli were generally considered to be able to form only in subaerial conditions, during the phreatomagmatic eruption till lately. Rocks exposed in quarry were probably formed during the Surtseyan eruption in shallow subaqueous setting. According to thin section lava flows are containing pseudomorphosis phenocrysts of olivine and...

The aim of this thesis is to investigate how Dagens Nyheter and The New York Times are framing the climate crisis in their news reporting during the period 1-30 November 2020. The thesis is based on Robert Entman’s theory on framing, Shanto Iyengar’s theory on episodic and thematic framing and Maxwell E. McCombs and Donald Lewis Shaw's theory on agenda setting as a metatheory for discussion. The research questions are: (1) Which frames are being used by Dagens Nyheter and the New York Times in their news reports on the climate crisis during the period 1-30 November 2020?, (2) To what extent are these frames being used in each newspaper? and (3) To what extent do the newspapers use thematic and episodic frames?. The material consists of 26 articles from Dagens Nyheter, and 35 from The New York Times. By using both a quantitative content analysis and a qualitative content analysis, we analyzed the chosen material. Research question (1) showed that the frames that were being used were politics, environmental impact, weather/natural disasters and economy. Research question (2) showed that politics/government and responsibility were the dominant framework in both newspapers, followed by environmental impact, weather/natural disasters and economy. Research question (3) showed that the majority of the articles in both newspapers had a thematic framework. One of the differences that was identified between the newspapers was that The New York Times used thematic frames to a greater extent than Dagens Nyheter. Based on Iyengar’s theory it is therefore reasonable to assume that The New York Times portrayal of the climate crisis might have a greater effect on the public opinion than Dagens Nyheter. Dagens Nyheter, however, used episodic frames to a greater extent, which according to Iyengar often evokes stronger emotional reactions from the recipients.The study’s chosen theories proved to be a good fit for describing and explaining how climate related articles are being framed in the papers.

This bachelor thesis examines how Swedish Television frames news about gang violence and explains which actors that appear in news articles on this field. News about this societal problem have started to appear more frequently in media publications during the last years which motivates the implementation of the study.   The analysis reveals that news about gang violence to a large extent is being framed as a question for politics. This is demonstrated in articles where the problem is framed as a conflict between political parties which proposes different solutions. Gang violence is also framed as something that the government should take responsibility for and therefore not a societal problem that individuals can solve themselves. Most of the articles are framed in a thematic, more general than specifik, perspective and episodic frames do not get that much coverage. There are mostly politicians that occur in articles about gang violence and thus the actors who have the opportunity to set the media agenda.  News articles published on the online edition of Swedish Television in September 2020 have been used as study material. This was a period during the year of 2020 where most news articles about gang violence were published. The method applied was a combined quantitative and qualitative content analysis. The theoretical framework consists of McCombs &amp; Shaws agenda setting theory and also three framing theories formed by Entman, Iyengar and Semetko &amp; Valkenburg. The frames used in the study are the conflict frame, human-interest frame, economic consequences frame, responsibility frame, morality frame, thematic frame and episodic frame.

Over the past 4 and a half years, I have studied contemporary art and seen countless artworks being made in an academic setting. In doing so, I have come to the realization that religious content is rare in today’s time. While it is not actively discouraged, the environment I am in and the current art community does not seem to be particularly interested in merging the two concepts. Without understanding why, I subconsciously kept art and my faith as separate entities for the first few years of my higher education. But as I matured and developed my own artwork, I began to feel as though my identity and my interests should be rooted in my relationship with God. Upon this reflection, I began looking for ways to make Christian art in a contemporary setting that could also be accepted by those who do not share my faith.

Aim: The purpose of this study is to describe the intervention process at a psychiatric clinic in Vietnam, from evaluation to goal setting, and how the staff choose occupation-based intervention for their patients. Method: This study is a qualitative study with inductive approach where the data collection is based on a semi-structured interview with the health care staff at a psychiatric clinic in Vietnam. The respondents consisted of a total of ten participants and were required by a purposive sample. Content analysis according to Kristensson (2014) was used to examine the data. Result: The findings from the result revealed that the clinic work without a standard procedure where the staff evaluates and assess their patient from their own experience. They also interview and observe the patients without an aim. The result also showed that the clinic offers different occupation-based interventions where the doctor decides occupation-training but not in consultation with the patient. It was revealed that the purpose of the occupation is to make the patients independent. The last finding was that the staff has a lack of individual goal setting and the general goal is for patients to get healthy. To see if the patients achieve improvement, observations are made without aim. Conclusion: The study concludes that the health care staff at the clinic has found their strategies using their own experience, for evaluating and assessing their patients.
