What factors contribute to the success of an experiment? Should experimentation in cybersecurity differ fundamentally from experimentation in traditional sciences?
We will be dedicated to identifying some of the features that characterize science, to recognizing some of the foundational obstacles faced by scientists, and to understanding what it means to implement (for example) internal validity, external validity, and replication/recreation in one's experimental practice.
Digital Scholarship (Cross-listed with INFSCI 3150, LIS 2975, & LIS 3970) Contemporary research and scholarship is increasingly characterized by the use large-scale datasets and computationally intensive tasks. Vast amounts of data are used by scholars to better map the cosmos, build more accurate earth system models, examine in finer detail the structures of living organisms, and gain new insights into the behaviors of societies and individuals in a complex world. Similarly, humanists are rapidly integrating newly digitized corpora, digital representation of cultural artifacts and spatial and temporal indexed data into their scholarly endeavors. This course will chart the development of digital scholarship from the beginning of the use of models and abstracted forms to conceptualize and represent knowledge and physical phenomena to state-of-the-art projects today that are transforming the nature of inquiry in many disciplinary domains. The course will be descriptive in nature. The goal will be to understand digital scholarship in terms of high-level methodological approaches and conceptual frameworks as well as to examine the technological, academic and social contexts that underpin successful endeavors. Case studies of exemplary state-of-the-art projects will be the vehicle for exploring the ways in which scholars, using internet-based open data, technologies and tools are dramatically expanding the problem space of domain scholarship in many areas and creating new methods for analysis of information and presentation of research results. A focus will also be on the natural role of collaboration and communication in digital scholarship.
