Bio 260 – Microbiology – Pathogen  Goal – Become adept at gathering and presenting information in the field of microbiology Project – Profile your assigned microbial pathogens or family of pathogens. Create an informative written report. The report will be submitted over Canvas. The profile should include   ·         Microbe identity –Genus and species, gram (+) or (-), growth patterns, etc. ·         Microbe location – Geographical specifics (ex. Malaria is found in warm, wet regions near the equator), common places in environments (ex. Helicobacter pylori is found in the stomach) ·         Pathogen mechanisms – Is this a pathogen? How? ·         Medical treatment – How do we fight this pathogen? ·         Anything else interesting? History? How can we study it? Does it grow on certain differential media? How would you stain it? Report ·         2000 words (single space size 12 times new roman font) report profiling your microbe. Word count does not include a bibliography. No quotations allowed. ·         Report should contain all the info the talk does and more detail on what makes your microbe special. ·         Report should be informative and in the style of Wikipedia articles. There should be no personal reflections. ·         References must be incorporated into the text so that it is clear what each reference refers to. ·         References must be present for every sentence which is not common knowledge. This means most sentences. Content Requirements and Grading Rubric Report Content Below are suggestions regarding the content of your report. ·         History of microbe ·         Description of microbe ·         Description of pathogen mode of action and medical treatments available ·         Impact of the pathogen in the environment/world ·         Other things you find interesting (this will depend heavily on your microbe)       References References should be done in MLA  or APA style with a complete bibliography on a separate slide. In-text references should be a superscript number (1) with references numbered in the order in which they appear (2). Some statements may be referenced in more than one source (1,2). Anything not ‘common knowledge’ should be cited. For this course, you may consider anything we have discussed in class to be common knowledge. Scientific sources can be found on PubMed or Google Scholar.

“My Canada” project students envision—they make—a different Canadian politics. This reimagining must be politically grounded; it does not start from a blank slate. It is based in the Canadian politics of the contemporary moment with their, inter alia, geography, colonial history, fragmentations, international relations, and crises. The transformation must also be realistic in the sense that it starts in existing relations of power and antagonistic and competing interests (i.e. if a student wants to explore changing federal policy to effectively address the global climate crisis, the power of fossil capital dictates that the issue of pipelines cannot simply be wished away). The project is not pie-in-the-sky fantasy; it is materially grounded. Contrary to appearances, and dominant representations in the corporate media, Canadian politics are always changing. The “My Canada” project demands that students make themselves thinking and acting participants in this change. Through the project, each student answers four questions involving political transformation, synthesized as an essay. First, what political change do I want to see realized in Canadian politics? This question amounts to a diagnosis of what aspect of Canadian politics (i.e. policy, institution, cultural practice) the student sees as not serving her/his interests and/or values. Second, what status-quo oriented social forces (both internal and global) oppose this change and why, and what transformative social forces (both internal and global) support this change and why? And third, how do exist and contentious power relations have to change to produce the politics I seek? These are the realistic political questions in the sense that they require identification of those social forces with which the student can align her/his political project, or from which the student can expect support, and those social forces antagonistic to the political project. They also demand consideration of the manner through which power relations have to be rebalanced in favor of the sought after change. Fourth, how would political change be institutionally expressed? This question recognizes that, once actualized, political change is “locked into” political institutions in law and/or governing apparatuses; that the moment a political goal is realized the will to transform morphs into the will to preserve What is politically possible or “realistic” in Canadian politics is not given or natural but determined by the actually existing balance of power between competing interests. This project empowers students to recognize that another Canadian politics is possible and that they play a part in creating them. Student projects must employ concepts learned in the course and indicate a clear and accurate understanding of these concepts. They must also reflect the student’s own analysis. Projects are not to be collections of quotations, direct or indirect, from other sources. Each project/essay must be researched, not the least because this accelerated course does not have sufficient time to review all of the material necessary to successfully complete the project/essay. Each essay must cite at least FOUR academic sources (i.e.academic books and peer-reviewed journal articles). Do not submit a paper that has not engaged with published scholarly literature. The Okanagan College library has a good selection of databases for electronic, full-text journals such as ProjectMuse, JStor, ProQuest, and Academic Search Elite. Students may use the course textbook, but it does not count as one of the four required academic sources. Additionally, articles from ordinary magazines, say Time or The Economist, and internet sites do not count as academic sources. In order for all written work to be graded, it must be properly formatted (12 point font, double-spaced with proper margins) and prefaced with a cover page clearly indicating the student’s name and ID number. Assignments that do not conform to these criteria will not be accepted for assessment

There will be three entries—one from each week (weeks 11, 12 and14). Each entry should take at least two readings including optional readings/video (the film is required to be included in week 12) and explore one idea or topic or issue that strikes you as important. As a point of departure, you may want to show how your reaction to the readings/film/lecture/discussion fits with (or doesn’t) previously or currently-hold beliefs, you may want to state how the issues (including class lecture) raised are relevant to your own experiences. To be successful, you must go beyond the point of departure; be both critical and analytical. What is the deeper significance of ideas or issues? You will have to be critical both about the readings/film/video and about your point of view. Please note Font 12, APA format, Word count. The Word document assignment should be saved/uploaded under your full name and course number.   * ONLY USE COURSE READING SOURCES, NO OUTSIDE SOURCES ALLOWED *
