When the Messenger is More Important than the Message: An Experimental Study of Evidence Use in Francophone Africa

Background: Epistemic injustices are increasingly decried in global health. This study aims to investigate whether the source of knowledge influences the perception of that knowledge and the willingness to use it in francophone African health policy-making context. Methods: The study followed a randomized experimental design in which participants were randomly assigned to one of seven policy briefs that were designed with the same scientific content but with different organizations presented as authors. Each organization was representative of financial, scientific, or moral authority. For each type of authority, two organizations were proposed: one North American or European, and the other African. Results: The initial models show that there was no significative association between the type of authority and the location of the authoring organization and the two outcomes (perceived quality and reported instrumental use). Stratified analyses highlighted that policy briefs signed by the North American/European donor organization were perceived to be of lower quality than policy briefs signed by the African donor organization. For both perceived quality and reported instrumental use, these analyses found that policy briefs signed by the North American/European university were associated with higher scores than policy briefs signed by the African university whereas policy briefs signed by the North American/European regional office or international organization were associated with lower score than those signed by the African regional office of the international organization. Conclusion: The results confirm the significant influence of sources on perceived global health knowledge and the intersectionality of sources of influence. This analysis allows us to learn more about organizations in global health leadership, and to reflect on the implications for knowledge translation practices.

Effectiveness of Self-Explanations Strategy in Developing Physical Concepts and Awareness of future envisioning of secondary stage students: فاعلية استراتيجية التفسيرات الذاتية في تنمية المفاهيم الفيزيائية والوعي باستشراف المستقبل لدى طلاب المرحلة الثانوية

Thesis Objectives: The thesis aimed at investigating the effectiveness of using Self-Explanations Strategy in developing physical concepts and the awareness of future envisioning of secondary stage students. To achieve the research objectives, the quasi-experimental approach was used through applying the experiment to two groups (the control and the experimental groups). The sample comprised (51) students; (25) at first secondary term students in the experimental group and (26) students in the control group. Thesis procedures: The scientific content of chapter seven, entitled "gravity" in the physics textbook for the first secondary grade students (second term), was structured and organized according to the philosophy and nature of Self-Explanations Strategy. Then, two tools were prepared; the physical concepts test and the awareness of future envisioning scale. The Validity and reliability of the two tools were applied through applying them on a pilot group of (30) students. They were pre-applied, then the experimental group was taught using Self-Explanations Strategy and the control group was taught using the traditional method. Then, the thesis tools were post-applied to get the raw scores to apply the statistical processing in order to get the results. Thesis results: The results revealed the effectiveness of Self- Explanations Strategy in in developing physical concepts and the awareness of future envisioning. Whereas there statistically significant differences at (a≤0.05) level were existed between the mean scores of the control and the experimental groups students in the post test of concepts as well as the future awareness scale in favor of the experimental group.

Affect in science communication: A data-driven analysis of TED talks

Science communication is changing. It is increasingly directed not only at peers but at the public in general. Accordingly, understanding the circumstances under which audience members engage with scientific content is crucial to improving science communication. In this article, we investigate the role of affect on audience engagement with a modern form of science communication: TED talks. We examined how affect valence---a net positive or negative affect---and density---the proportion of affective words---are associated with a talk's popularity---reflecting views and likes---and polarity---reflecting dislikes and comments. We found that the valence of TED talks was associated with both popularity and polarity, with positive valence being linked to higher talk popularity and lower talk polarity. Density, on the other hand, was only associated with popularity, with higher affective density being linked to higher popularity---even more so than valence---but not polarity. Moreover, we observed that the association between affect and engagement was partially moderated by talk topic. Specifically, whereas higher density was related to higher popularity across most topics, valence seemed to particularly impact the popularity and polarity of TED talks on social topics, which regularly discuss polarizing issues such as race or political conflicts. We discuss implications of our findings for increasing the effectiveness of science communication.

Designing and Evaluating an Educational Website for Osteoarthritis

Aim: Using educational websites can be effective in enhancing the health-related knowledge of patients suffering from osteoarthritis. This study aimed to design and evaluate an educational website to improve the awareness of patients with osteoarthritis. Method: This is a descriptive-applied study. Having reviewed valid scientific articles retrieved from Medline (through PubMed), Scopus, and Google Scholar databases, the contents required for the website were identified and classified. Then, the scientific content extracted from the articles was evaluated by general physicians and Ph.D. of physical medicine and rehabilitation. Different sections of the website were designed by "Google sites," and the content was published. In the last stage of the research, the osteoarthritis educational website was evaluated by students of medicine and health information technology in terms of technical performance by a standard questionnaire. Results: In this study, an educational website was designed to educate patients with osteoarthritis. Users can log in to the website and learn about symptoms, consequences, predisposing factors, pain relief exercises, nutritional information, and self-care programs. The content provided on the website includes three main sections of general disease information, clinical information, and disease self-care information, which physicians evaluated in the first phase. According to the content evaluation results extracted from the studies and the questionnaire's analysis, the designed website had a good quality. The average scores of the questions related to website usability, screen capabilities, terminology and information, learning ability, and overall website capability were 7.79, 8.15, 8.4, 8.08, and 8.03, respectively, which were at a "good" level. Conclusion: At the end of this research, an educational website for osteoarthritis was created. Patients can access the site via the link and receive educational information about symptoms, consequences, predisposing factors, exercises to reduce pain, self-care, and nutritional information.

Kazimir Malevich: Approaching The New System

This dissertation examines Kazimir Malevich’s art and writing with a view to establishing that they combine a strain of strict methodological reductionism with an equally well-marked esotericism. It strives to prove that although this feature of Malevich’s work was common among vanguard artists and thinkers, there are also highly idiosyncratic qualities in the way Malevich reconciled these two threads. An ensuing goal of this work is to propose how to complete an unfinished 1927 film script by Kazimir Malevich titled “Artistic and Scientific Film—Painting and Architectural Concerns—Approaching the New Plastic Architectural System.” <div>The question regarding the confluence of science and mysticism in Malevich’s work— the primary concern of this dissertation—requires tracing in the artist’s art and writings the presence of ideas belonging to these worldviews traditionally considered to be antithetical to each other. This dissertation establishes Malevich’s relationship with mysticism and strains of thought that resemble scientific content and approach. Among the latter, this work investigates Malevich’s interest in the geometry of the fourth dimension, draws parallels between the artist’s concern for visualizing infinity and the problems of set theory, and examines the role of imaginary numbers in Malevich’s worldview. To complete the analysis of Malevich’s exploration of the concept of space prominent in the aforementioned mathematical themes, this dissertation examines the artist’s interest in investigating the space of the cosmos. It also establishes that Malevich’s ideas were not only influenced by the scientific advancements in electromagnetism but also by the theories of thermodynamics, which together with the former relay a view of the world where all processes, organic and inorganic, are understood as the product of the transformation of energy. In Cubism and Futurism: Spiritual Machines and the Cinematic Effect, R. Bruce Elder draws attention to the early twentieth-century thinkers’ view of cinema as an electromagnetic machine. This dissertation examines Malevich’s relationship with the cinematic art and its reception in Russia during Malevich’s most productive years. This work concludes with having satisfied its larger objective: to envision a possible scenario of how Malevich’s unfinished script could unfold. It contains the copy of the original script, its proposed finale, and an essay that outlines how my investigation of Malevich’s intellectual landscape informed the decisions involved in inferring the concluding shot sequences of the artist’s only cinematic work.<br></div>

Theology of Hope Amidst the World’s Fears

Fear is a social phenomenon that develops in people facing a crisis, such as a pandemic. For instance, the entire world is currently exposed to Covid-19 pandemic, causing great fear. In the Bible, Jesus’ disciples were terrified of sinking in their boat during a storm. Although these two scenarios are different, the response is the same. Fear produces stress and anxiety disorders when not appropriately managed. This paper examines the causes of fear and how they can be addressed. Specifically, the study involves determining the cause of fear and proposing a strategy based on Hope, as described by Erich in the book Revolution of Hope which positively correlates with building fortitude and endurance. Surrendering or persisting is a dialectical choice, though theology fear does not give chances. Instead, Humans only survive by depending on God. This research was involved literature reviews by utilizing reference sources, including books, journal articles, and other scientific content.
