The Hashtags Rivalry behind the Controversial Bill : A comparative study on the Opposition and Support Movement of Omnibus Law Bill in Indonesia. / The Hashtags Rivalry behind the Controversial Bill : A comparative study on the Opposition and Support Movement of Omnibus Law Bill in Indonesia.Damayanti, Imelda January 2021 (has links)
A controversial bill aimed to stimulate investment and boost the economy in Indonesia, called the Omnibus Law Bill, is followed by both protest and support expressed in social media prior to its signatories in October 2020. During that time, the Twittersphere is packed with both the Opposition and Support movement of the bill, who both benefit from the use of hashtags. To distinguish an organic grass-roots movement from a propaganda that fits the agenda of the government and elite, a comparison study is conducted with a framework of top-down and bottom-up- mechanism of information virality (Nahon & Hemsley, 2013). The top-down mechanism combined with participatory propaganda theory is designated to explain the Support movement. Vice versa the bottom-up mechanism is combined with connective action theory designed to explain the Opposition movement as its character in line with a contemporary and digital protest movement (Bennett & Segerberg, 2012). As existing research only often studies both networks alone, this unique case provides an opportunity to compare both networks. A mixed-method of Social Network Analysis (SNA) and Topic Modelling used to differentiate the characteristics of both groups, based on both network structure and topics discussed. The finding in regards to the SNA is corresponding to the theoretical framework and previous studies. The loosely organized nature of connective action is reflected in several characteristics of the Opposition Network, in contrast to the element of coordination found in the Support Network. Findings from bi-term topic modeling, however, both contradict and support the hypothesis that suggests more variations in the topics within the Opposition Network as a result of the self-motivated participant and personalized messages (Leong et al., 2019).

Investigating MOOCs with the use of sentiment analysis of learners' feedback. What makes great MOOCs across different domains?Nefedova, Natalia January 2022 (has links)
Recently, distance education has become popular and has gotten much attention. Information and Communication Technology advances fostered distance learning creation and enabled individuals to participate in the education process via various web-based platforms and study entirely online. Thus, the notion of e-learning and distance learning emerged. Massive Open Online Courses (MOOCs) appeared as part of e-learning in 2008 and attracted great interest, especially during the COVID-19 pandemic. It was anticipated that this kind of study also could be integrated into higher education and revolutionize the learning approach. However, several issues related to MOOCs limit their full potential. One of the most significant problems is substantial rate of learners’ attrition. It was discovered that only 5-10 percent of MOOC learners complete a course. This thesis aims to examine what influences individuals’ decision to leave MOOCs and how learners perceive various course components to get ideas regarding how MOOCs could be enhanced. To do this, the mixed-method study was undertaken where quantitative data analysis of learners’ reviews from discussion forums and qualitative interviews were adopted. It allowed to get two perspectives and broaden the thesis out- come. For the current research, data was collected from six courses in three different subjects-«Health», «Art and Humanity/Design» and «Computer/Data Science». In the first part of the work, sentiment analysis and topic modeling using Python packages were carried out, and then the results were used to construct an interview questionnaire. Lexicon-based sentiment analysis technique and LDA topic modeling algorithm were utilized and proved to be robust methods to extract texts’ polarity and peoples’ opinions. In the qualitative part, 19 topics of discussion were identified, which were consolidated into eight topics with higher abstraction – materials, instructor, content, time, assignment, feedback, program(course), and algorithms. Then during the qualitative part, participants expressed their opinions regarding these topics, and analysis codes were predefined, and new topics did not emerge. The results showed learners’ perceptions related to presented topics and how these aspects influence experience with MOOCs. The outcome also showed a slight disparity between different subject learners, in both qualitative and quantitative studies identified topics of discussion were not exactly the same, showing that learners from different educational domains tend to discuss different themes.

Effekt av interventioner med syfte att öka följsamhet till behandling med fysisk aktivitet hos patienter med muskuloskeletal smärta : En litteraturstudie / Effect of interventions aimed at increasing adherence to treatment with physical activity in patients with musculoskeletal pain : A literature studyEnglund, Maria January 2022 (has links)
SAMMANFATTNING Bakgrund: Muskuloskeletal smärta är en av de främsta orsakerna till både sjukskrivning och hälso- och sjukvårdskonsumtion i de flesta västerländska samhällen. Muskuloskeletal smärta definieras som smärta i rörelseorgan såsom muskler, leder, skelettdelar eller tillhörande mjukdelar. I behandling av muskuloskeletal smärta ingår ofta fysisk aktivitet. Fysisk aktivitet definieras, som all kroppsrörelse som ökar energiförbrukningen utöver den energiförbrukning som vi har i vila. För att fysisk aktivitet skall ha önskad effekt krävs följsamhet till den fysiska aktiviteten. Syfte: Syftet är att med hjälp av andra studiers resultat sammanställa effekt av interventioner vars syfte är att öka följsamhet till behandling med fysisk aktivitet hos patienter med muskuloskeletal smärta. Metod: Systematisk litteraturstudie. Sökning genomfördes i databaserna PUB Med, CINAHL, AMED och PEDRO. Artiklarna granskades med mall för kvalitetsgranskning av randomiserade studier samt att en GRADE bedömning utfördes med bedömningsunderlag från Statens beredning för medicinsk och social utvärdering (SBU). Resultat: Vid litteratursökning återfanns 514 artiklar som motsvarade syfte och frågeställningar. Efter genomgång av titel samt abstract fanns 38 artiklar kvar, efter genomläsning av hela studien fanns 10 artiklar kvar som inkluderades i litteraturstudien.De 10 artiklarna hade varierande grad av kvalitet. Ingen av studierna hade fullgod kvalitet på samtliga delar som ingår vid kvalitetsgranskningen. Evidensgradering enligt GRADE visar måttligt underlag för beteendemedicinska interventioner för att öka följsamheten till fysisk aktivitet för vuxna patienter med muskuloskeletal smärta. Konklusion: Denna litteraturstudie visar ett svagt sambandavseende om beteendemedicinska interventioner kan öka följsamhet till fysisk aktivitet hos vuxna med muskuloskeletal smärta. Vid stödjande aktiviteter fann man inte någon positiv effekt på följsamhet till fysisk aktivitet hos vuxna patienter med muskuloskeletal smärta. / ABSTRACT Background: Musculoskeletal pain is one of the leading causes of both sick leave and health care consumption in most western societies. Musculoskeletal pain is defined as pain in organs such as muscles, joints, skeletal parts or associated soft tissues. Treatment of musculoskeletal pain often includes physical activity. Physical activity is defined as all body movement that increases energy consumption in addition to the energy consumption we have at rest. In order for physical activity to have the desired effect, compliance with the physical activity is required. Objective: The aim is to use the results of other studies to compile the effect of interventions whose purpose is to increase adherence to treatment with physical activity in patients with musculoskeletal pain. Methods: Systematic review. The search was conducted in the databases PubMed, CINAHL, AMED and PEDRO. The studies were assessed according to template for quality review of randomized studies and GRADE from Statens beredning för medicinsk och social utvärdering. Results: A literature search found 514 articles that corresponded to purpose and issues. After reviewing the title and abstract, there were 38 articles left, after reading the entire study, there were 10 articles left that were included in the literature study. The 10 articles had varying degrees of quality. None of the studies had full quality on all parts included in the quality review. Evidence grading according to GRADE shows a moderate basis for behavioral medicine interventions to increase adherence to physical activity for adult patients with musculoskeletal pain. Conclusion: This literature study shows a weak correlation regarding whether behavioral drug interventions can increase adherence can increase adherence to physical activity in adults with musculoskeletal pain. In supportive activities, no positive effect was found on compliance with physical activity in adult patients with musculoskeletal pain.

DO PATIENTS MANAGED WITHIN A TRIAL EXPERIENCE DIFFERENT OUTCOMES THAN THEIR COUNTERPARTS MANAGED OUTSIDE THE TRIAL? A SYSTEMATIC REVIEW AND META-ANALYSIS OF RANDOMIZED AND OBSERVATIONAL STUDIES.Fernandes, Natasha A. 10 1900 (has links)
<p>Context: It is unclear whether the construct of a randomized controlled trial (RCT) itself could confer benefit or harm to trial participants beyond any effect of the experimental treatment under study (trial effect).</p> <p>Objective: To determine whether there is a trial effect appreciated by RCT participants (insiders) compared to similar patients who do not participate (outsiders). Although we are most interested in the pragmatic comparison of insiders to outsiders, we will also conduct the explanatory comparison of insiders to outsiders when the intervention is the same.</p> <p>Data Sources: We searched electronic health research databases, including CENTRAL (1960-2010), MEDLINE (1966-2010), EMBASE(1980-2010) and PsycINFO (1880- 2010).</p> <p>Study Selection: Eligible studies included those that reported the outcomes of insiders and a group of parallel or consecutive outsiders and reported the same health outcome at the same endpoint.</p> <p>Results: We included 147 articles out of the 42493 identified in our initial search. Five out of the 147 studies randomized patients to be insiders or outsiders, the remaining were observational designs. The heterogeneity of our overall result was reduced by grouping studies based on whether the intervention being investigated was effective and whether treatment inside and outside of the RCT was the same or different. There was no significant difference in outcomes between insiders and outsiders when the experimental intervention was ineffective (standard mean difference [95% confidence interval]: -0.03 [-0.1, 0.04]), or when it was effective and received by both insiders and outsiders (0.04 [-0.04,0.13]). If the experimental intervention was effective but was not administered to outsiders, they experienced worse health outcomes (-0.36 [-0.61, -0.12]).</p> <p>Conclusions: There is no evidence to support any benefit or harm associated with trial participation. There is some evidence that better outcomes are experienced by insiders who had access to effective treatments not offered or available to outsiders.</p> / Master of Health Sciences (MSc)

Success and confidence in, or inclusive of, undergraduate chemistry students surrounding a collaborative learning intervention, encouragement of metacognition, and a multifaceted scholarship support programLeake, Maggie Erin 09 August 2022 (has links)
Student success in chemistry has been linked to a wide range of factors. Some of these factors are familiar, easily quantified measures; colleges typically rely on factors like high school GPA and measures of aptitude to make admission decisions or set course prerequisites. Success in chemistry courses can be linked to these measures, and math aptitude scores in particular are often used as prerequisites for introductory chemistry courses. However, success in chemistry can also be affected by factors like motivation, peer interactions, sense of belonging, and metacognitive skill. Additionally, outcomes in chemistry and other STEM courses like math and physics have been repeatedly found to be inequitable.
In Chapter I, background information relevant to the subsequent chapters will be discussed. In Chapter II, group quizzes were implemented as a collaborative learning tool in a large-lecture format first-semester organic chemistry classroom. Chapter III describes a multifaceted scholarship support program for chemistry, physics, and math majors. This program strove to support traditionally underrepresented groups in chemistry through several components, including a team-building course and mentorship. Heavy emphasis was placed on building a peer support network. In Chapter IV, confidence surveys were implemented to encourage student metacognitive monitoring. Student success and confidence were assessed through three scopes: as they pertained to the overall course, by exam, and by individual topic.

Hearing the Sublime: Signification of the Sublime in Solo Piano Literature of the Nineteenth CenturyHull, Gretchen Lindsay January 2019 (has links)
Though many philosophers and music theorists have admitted the signification of the sublime in music as a possibility, the nature and mechanism of that signification has not yet been treated at length with a methodology familiar to musicians or native to music theory. Within this dissertation I have conducted a survey of the philosophy of the sublime as understood by Edmund Burke (1729 – 1797), Immanuel Kant (1724 – 1804), Friedrich Schiller (1759 – 1805), and Arthur Schopenhauer (1788 – 1860), with references to other contemporary philosophers and writers. The broader influence of the sublime in regards to German-speaking regions and certain musical composers was also considered. I then gathered from the above philosophers’ categories and definitions of the sublime a constellation of objects, qualities, and emotional states associated with the sublime. These functioned as signs or signifiers of the sublime, whose paths of signification were considered or determined with use of semiotics and topic theory, with reference to the work of Danuta Mirka, Raymond Monelle, and Leonard Ratner. Making reference to score examples listed in the list of figures, I implemented these techniques in analyses of Ludwig van Beethoven’s Sonata No. 30 in E Major, Op. 109 and Sonata No. 32 in C, Op. 111 as well as Franz Liszt’s “Mazeppa,” from the Études d’exécution transcendante, “Funerailles” from Harmonies Poétiques et Religieuses III, S. 173, and “Marche funèbre, En mémoire de Maximilian I, Empereur du Mexique” in from Années de pèlerinage III, S.163. / Music Performance

LISZT’S SONATA IN B MINOR: ANALYTICAL AND HERMENEUTIC INQUIRIESKim, Yumi January 2019 (has links)
This dissertation pursues the following three objectives: (1) a comprehensive formal analysis of Franz Liszt’s sonata in B minor that combines adequate analytical models; (2) various hermeneutic approaches to the sonata that trace thematic and expressive transformations and deviational elements from sonata conventions; and (3) a comprehensive interpretation of the sonata analysis and the hermeneutic analyses based on historical, religious, and political contexts around Liszt and the sonata, which will differentiate this dissertation from preceding research on the sonata and other sonata genres in the nineteenth century. Chapter 1 begins with a literature review, focusing on (1) the sonata’s formal analyses and (2) programmatic approaches. Considering the formal boundaries of the sonata are still disputable in former research, I argue that the sonata strongly demands appropriate analytical methodologies in order to uncover its exceptional form. These methodologies include James Hepokoski’s and Waren Darcy’s sonata theory (2006), Leonard Meyer’s “secondary parameters” (1989), and Peter Smith’s “dimensional counterpoint” (2005), which will be discussed in Chapter 2. Hepokoski’s and Darcy’s sonata theory reveals the conventions of eighteenth- and nineteenth-century sonatas and suggests hermeneutic interpretations that result from deviations from these conventions. Secondary parameters and dimensional counterpoint are critical in shaping musical processes and form. I provide a three-step sonata analysis based on the analytical ground that combines these methodologies. My analysis offers a comprehensive view of the entire sonata as a one-movement sonata form, including structural, motivic, and narrative analyses. Chapter 1 also describes several programmatic approaches that Liszt scholars have developed. However, an obsession with the good/evil dichotomy in former research narrows narratives of the sonata. Considering that the sonata presents five motto themes, interpretations of the sonata may be more extensive and complex than previous research has found. I develop various and distinctive hermeneutic readings of the sonata in Chapter 3, which includes the following three sub-sections: 1) Topical approach; 2) Narrative approach; and 3) Lacanian approach. The topical approach investigates how different topical significations are manifested in Liszt’s sonata in nineteenth-century historical and cultural contexts. The narrative approach concentrates on five mottos presented in the sonata and their motivic and expressive transformations. The Lacanian approach concentrates on a lack of strong cadences in the sonata, relating to Lacan’s famous concept, objet petit a, an unattainable object of desire. Then, I continue to use the Lacanian viewpoint to interpret an unresolved fully-diminished seventh harmony as a Sinthome, a symptom that can never be healed. In Chapter 4, I relate Liszt’s religious convictions and various struggles to bring about another hermeneutic reading in the political, religious, and theological contexts around Liszt and the sonata, by revisiting my interpretations in Chapter 3. / Music Theory
