This volume addresses fundamental issues in the philosophy of science in the context of two most intriguing fields: biology and economics. Written by authorities and experts in the philosophy of biology and economics, Mechanism and Causality in Biology and Economics provides a structured study of the concepts of mechanism and causality in these disciplines and draws careful juxtapositions between philosophical apparatus and scientific practice. By exploring the issues that are most salient to the contemporary philosophies of biology and economics and by presenting comparative analyses, the book serves as a platform not only for gaining mutual understanding between scientists and philosophers of the life sciences and those of the social sciences, but also for sharing interdisciplinary research that combines both philosophical concepts in both fields. The book begins by defining the concepts of mechanism and causality in biology and economics, respectively. The second and third parts investigate philosophical perspectives of various causal and mechanistic issues in scientific practice in the two fields. These two sections include chapters on causal issues in the theory of evolution; experiments and scientific discovery; representation of causal relations and mechanism by models in economics. The concluding section presents interdisciplinary studies of various topics concerning extrapolation of life sciences and social sciences, including chapters on the philosophical investigation of conjoining biological and economic analyses with, respectively, demography, medicine and sociology.

The undergraduate organic chemistry course is a prerequisite course for many students who plan to pursue careers in chemistry and chemical engineering. It also serves those students who wish to pursue professional careers in medicine, dentistry, and veterinary sciences. Previous research on student learning in organic chemistry shows that students struggle to understand ideas such as acid-base reactions and structure-property relationships which are foundational concepts on which more complex concepts are built. Furthermore, the typical organic chemistry course emphasizes students use of the electron-pushing formalism to represent how bonds are formed and broken in chemical reactions. Expert organic chemists use this formalism to represent predicted reaction mechanisms that explain the formation of products. Numerous studies have characterized student difficulties using electron-pushing mechanisms in an expert-like way as well as associating underlying chemical principle with the representations. We suggest that deep understanding of chemical reactions and their underlying chemical principles can be developed by engaging students in causal mechanistic explanation as part of a transformed organic chemistry course that emphasizes students using their knowledge of electrostatics, structure-property relationships, and energy to engage in explanation of chemical phenomena. Our goal is to engage students in as specific type of explanation called in casual mechanistic explanation which includes reasoning about the underlying causal factors in conjunction with the underlying entities and their activities that bring the phenomenon about. The studies reported here use a qualitative approach to elicit student' written explanations and drawn reaction mechanisms for various chemical reactions. Students were sampled at multiple time points over the course of their two-semester organic course to investigate how student reasoning changes overtime. Students participants were enrolled in either the beforementioned transformed organic chemistry course or were enrolled in an untransformed course that we refer to as the traditional context. This traditional context served as a control group for which to compare possible changes in reasoning for students enrolled in the transformed course sequence. Findings suggest that student engagement in causal mechanistic reasoning varies depending on students' general chemistry and organic chemistry course experience as well as the nature of the prompt eliciting the reasoning. Findings also suggest that students are generally capable of drawing mechanistic arrows that would generally be considered correct, however triangulating student reasoning with a detailed analysis of students' drawings, we found that typical organic chemistry assessment items that lack a reasoning component may overestimate student understanding. Our investigations also revealed student difficulties invoking the correct nucleophilic substitution process for a given reaction. Students often invoked an SN1 mechanistic process incorrectly, despite their engagement in casual mechanistic reasoning. Implications of these findings for organic chemistry instruction and assessment are discussed along with implications for future research.
Evaluating Evidence of Mechanisms in Medicine

This book is open access under a CC BY license. This book is the first to develop explicit methods for evaluating evidence of mechanisms in the field of medicine. It explains why it can be important to make this evidence explicit, and describes how to take such evidence into account in the evidence appraisal process. In addition, it develops procedures for seeking evidence of mechanisms, for evaluating evidence of mechanisms, and for combining this evaluation with evidence of association in order to yield an overall assessment of effectiveness. Evidence-based medicine seeks to achieve improved health outcomes by making evidence explicit and by developing explicit methods for evaluating it. To date, evidence-based medicine has largely focused on evidence of association produced by clinical studies. As such, it has tended to overlook evidence of pathophysiological mechanisms and evidence of the mechanisms of action of interventions. The book offers a useful guide for all those whose work involves evaluating evidence in the health sciences, including those who need to determine the effectiveness of health interventions and those who need to ascertain the effects of environmental exposures.

Causal reasoning is one of our most central cognitive competencies, enabling us to adapt to our world. Causal knowledge allows us to predict future events, or diagnose the causes of observed facts. We plan actions and solve problems using knowledge about cause-effect relations. Without our ability to discover and empirically test causal theories, we would not have made progress in various empirical sciences. The handbook brings together the leading researchers in the field of causal reasoning and offers state-of-the-art presentations of theories and research. It provides introductions of competing theories of causal reasoning, and discusses its role in various cognitive functions and domains. The final section presents research from neighboring fields.

Reasoning about structure-reactivity and chemical processes is a key competence in chemistry. Especially in organic chemistry, students experience difficulty appropriately interpreting organic representations and reasoning about the underlying causality of organic mechanisms. As organic chemistry is often a bottleneck for students’ success in their career, compiling and distilling the insights from recent research in the field will help inform future instruction and the empowerment of chemistry students worldwide. This book brings together leading research groups to highlight recent advances in chemistry education research with a focus on the characterization of students’ reasoning and their representational competencies, as well as the impact of instructional and assessment practices in organic chemistry. Written by leaders in the field, this title is ideal for chemistry education researchers, instructors and practitioners, and graduate students in chemistry education.
