In this lesson, we delve into the System Requirement Specification (SRS) for our Image-Guided Neurosurgery (IGNS) project, outlining the critical steps to define software needs. We explore how to translate user requirements, like precise surgical tool tracking and planning, into clear functional and non-functional specifications, all while prioritizing patient safety through rigorous risk analysis and control measures.

🎯 Learning Objectives
• Understand the purpose and components of a System Requirement Specification (SRS).
• Identify user usage scenarios and their role in defining software requirements for medical devices.
• Learn how to conduct an initial risk analysis and implement risk control measurements in SRS.
• Differentiate between functional and non-functional requirements in medical software development.
• Explain the importance of incorporating safety, security, and regulatory standards into SRS.

Game Theory (ECON 159)

We discuss repeated games, aiming to unpack the intuition that the promise of rewards and the threat of punishment in the future of a relationship can provide incentives for good behavior today. In class, we play prisoners' dilemma twice and three times, but this fails to sustain cooperation. The problem is that, in the last stage, since there is then is future, there is no incentive to cooperate, and hence the incentives unravel from the back. We related this to the real-world problems of a lame duck leader and of maintaining incentives for those close to retirement. But it is possible to sustain good behavior in early stages of some repeated games (even if they are only played a few times) provided the stage games have two or more equilibria to be used as rewards and punishments. This may require us to play bad equilibria tomorrow. We relate this to the trade off between ex ante and ex post efficiency in the law. Finally, we play a game in which the players do not know when the game will end, and we start to consider strategies for this potentially infinitely repeated game.

Introduction to Political Philosophy (PLSC 114)

The concept of "general will" is considered Rousseau's most important contribution to political science. It is presented as the answer to the gravest problems of civilization, namely, the problems of inequality, amour-propre, and general discontent. The social contract is the foundation of the general will and the answer to the problem of natural freedom, because nature itself provides no guidelines for determining who should rule. The lecture ends with Rousseau's legacy and the influence he exercised on later nineteenth-century writers and philosophers.

00:00 - Chapter 1. Introduction: Social Contract and the General Will
25:04 - Chapter 2. Applications of the General Will

In this lesson, we take a deep dive into the FDA's Quality System Regulation (CFR 820), a foundational document for medical device development. Discover why understanding its definitions and requirements is crucial, especially the critical role of design controls in ensuring compliance and safety for medical software, and how this regulation shapes the entire development process from design to documentation.

🎯 Learning Objectives
• Understand the core purpose and scope of the FDA's Quality System Regulation (CFR 820).
• Grasp the concept of design controls and their application in medical software development.
• Distinguish between 'verification' and 'validation' and their roles in design processes.
• Learn about key documentation requirements, including design input, design output, and the design history file.
• Recognize the emphasis on formal documentation and procedures ("if it wasn't documented, it never happened").

Game Theory (ECON 159)

We discuss auctions. We first distinguish two extremes: common values and private values. We hold a common value auction in class and discover the winner's curse, the winner tends to overpay. We discuss why this occurs and how to avoid it: you should bid as if you knew that your bid would win; that is, as if you knew your initial estimate of the common value was the highest. This leads you to bid much below your initial estimate. Then we discuss four forms of auction: first-price sealed-bid, second-price sealed-bid, open ascending, and open descending auctions. We discuss bidding strategies in each auction form for the case when values are private. Finally, we start to discuss which auction forms generate higher revenues for the seller, but a proper analysis of this will have to await the next course.

00:00 - Chapter 1. Auctions: Common versus Private Values
08:16 - Chapter 2. Auctions: Winner's Curse in the First-Price Sealed-Bid Auction

Milton (ENGL 220)

Milton's characteristic use of simile is explored in Books One and Two of Paradise Lost. Particular attention is paid to how Milton's similes work to support, undermine, and complicate both the depiction of Satan and the broader thematic concerns of the poem, such as the ideas of free will and divine providence. The critical perspectives of Geoffrey Hartman and Stanley Fish are incorporated into an analysis of Satan's shield and spear and the simile of the leaves.
