Selected experiments to illustrate major biochemical principles and techniques. B M B 212 B M B 212 Elementary Biochemistry Laboratory (1)B M B 212 exposes students to techniques typically used in industrial and academic laboratories to isolate proteins, perform enzyme kinetics, characterize carbohydrates and lipids, and study molecular biology. Data interpretation and conceptual understanding are emphasized.Specifically, students determine a weak acid's buffer range with a pH meter; quantify protein concentrations using a spectrophotometer; partially purify acid phosphatase from wheat germ, using ammonium sulfate precipitation, centrifugation and dialysis; characterize acid phosphatase kinetics; subject glycogen to acid and salivary amylase hydrolysis, then compare products using thin layer chromatography; isolate plasmid DNA from E.coli, then digest the plasmid DNA with restriction enzymes and analyze the products using agarose gel electrophoresis; make soap from commercial oils and fats; and lastly, identify fatty acids using a gas chromatograph.Students write laboratory reports to present their findings and correlate theory with actual experimental results. Written quizzes assess conceptual understanding of experiments. Teaching assistant evaluations judge the student's level of laboratory skill achievement, preparation, and ability to work with others in a professional manner.A solid chemistry knowledge base (CHEM 012 and either CHEM 034 or 038), previous laboratory experience, and the ability to work with mathematical word problems are expected of all students enrolled in the course. Biochemistry focuses on the chemistry of living organisms. This course provides basic biochemistry laboratory skills and exposure to widely-used methodology to develop a fundamental understanding of biochemistry needed for advanced courses in the student's major and compatible with the student's career interests. Outside resources for the student include reserved books and a course web site: www.bmb.psu.edu/courses/daniel/BMB212/default.htm.
In the course, students learn how to analyze firms' financial statements and disclosures to determine how a firm's particular accounting choices reflect the underlying economics of the firm. As a result, the course strengthens students' ability to use financial statements as part of an overall assessment of the firm's strategy and valuation. The course is especially useful for anyone interested in working on the buy or sell side. The course provides both a framework for and the tools necessary to analyze financial statements. At the conceptual level, it emphasizes that preparers and users of financial statements have different objectives and incentives. At the same time, the course is applied and stresses the use of actual financial statements. For example, students learn how to detect when firms are managing earnings and/or balance sheets. It draws heavily on real business problems and uses cases to illustrate the application of the techniques and tools. If ACCT 2420 is not offered in a given year, Undergraduate students can take ACCT 7420. Please submit a permission request through Path@Penn.edu.
Were it our business to set the Nation's social policy, I would agree without hesitation that it is senseless for an enlightened society to deprive any children -- including illegal aliens -- of an elementary education. I fully agree that it would be folly -- and wrong -- to tolerate creation of a segment of society made up of illiterate persons, many having a limited or no command of our language. [Footnote 4/1] However, the Constitution does not constitute us as "Platonic Guardians," nor does it vest in this Court the authority to strike down laws because they do not meet our standards of desirable social policy, "wisdom," or "common sense." See TVA v. Hill, 437 U. S. 153, 437 U. S. 194-195 (1978). We trespass on the assigned function of the political branches under our structure of limited and separated powers when we assume a policymaking role as the Court does today.
Engages future teachers in studying diverse classroom, school, and community contexts; assessing elementary students' strengths, weaknesses, interests, and background knowledge; and implementing curriculum based on assessment results and context. 2b1af7f3a8
