This course examines international nuclear non-proliferation regimes and geopolitical situations as an important part in international peace and security. Via case studies, the course explores the history of nuclear weapon development and the establishment of nuclear non-proliferation regimes as well as nuclear disarmament agreements between the United States and Russia (formerly the Soviet Union) and the UN’s efforts to ban nuclear weapons.
The course further addresses the history of nuclear weapon development, use, and related, resultant negotiations, treaties, and subsequent political impact upon and by various governing bodies throughout the world. The course situates and reviews cases in the geopolitical context: nuclear development and possession in India, Pakistan, and Israel; the Cuban Missile Crisis; and Iranian nuclear development.
In addition, the possibility of further nuclear proliferation by Saudi Arabia, Egypt, Japan and Taiwan is discussed in relation to geopolitical interests, and North Korea's nuclear tests and South Korea’s nuclear option are debated in the context of North Korea’s nuclear threat and geopolitical strategy.

COURSE DETAIL
The contemporary world is facing many challenges in promoting peace, justice and reconciliation, ranging from armed conflicts to social inequality, from environmental degradation to interfaith tensions. These complex challenges continue to afflict many parts of the globe. In this context, some fundamental questions may be asked: how do we define life?; What does it mean to live a life of integrity?; How does my life relate to just, sustainable and inclusive peace?; How do the ideas for making the world more just and peaceful shape our own lives and careers of purpose and vice versa? Seeking to explore these questions deeply, this course presents foundational theories behind peace and social justice and applies these concepts to specific fields of inquiry and practice, including: colonization, violence, oppression, racism, sexism, human trafficking, poverty, climate change and complex issues of peacebuilding, humanitarian aid and development. Various strategies and attempts to create social change for the greater good through different individual and organizational platforms are analyzed and assessed too. Throughout the course, students gain an understanding of the strengths and constraints on theory and practice in the context of the creation of a culture of “human flourishing”, particularly in post-conflict societies, and engage in a variety of topics with self-reflective approach.
COURSE DETAIL
This course explores the significant achievements of behavioral economics, focusing on theoretical and empirical evidence. Unlike traditional economics, which assumes human rationality and standard preferences to understand decision-making and behavioral changes, behavioral economics expands human decision-making models based on new insights from psychology and other fields and introduces the concept of policy design and evaluation based upon insights into human behavioral change. Students will gain a thorough understanding of the fundamental concepts of behavioral economics; be able to critically evaluate the traditional economic theories on human rationality; and be able to compare and analyze the usefulness and policy implications of behavioral economics with those of traditional economics.
Prerequisites: Microeconomics, Basic Calculus
COURSE DETAIL
This course explores the transformative role of new information technologies (IT) and artificial intelligence (AI) in reshaping businesses. Its goal is to equip students with an in-depth understanding of essential economic principles that are crucial for operating and excelling in IT-enabled and/or AI-driven enterprises, while also highlighting the economic ramifications of IT and AI at various levels - including individual firms, broader markets, and society as a whole.
Students will delve into competitive market analysis and examine IT-specific economic challenges related to pricing, bundling, information asymmetry, and uncertainty. In addition, the module covers AI-centric topics such as automated decision-making and the broader economic effects of AI technologies. Key economic issues associated with IT (such as competitive markets, pricing strategies, and bundling) and foundational concepts like user lock-in, switching costs, and the network effect are discussed. Participants also gain insights into the workings of AI-enabled businesses and address AI-specific economic concerns, including automated decisions, algorithmic bias, and the influence of AI technologies on the job market.

This course examines linguistic phenomena relating to the structure of language and how those phenomena are formulated and explained under the framework of so-called Generative Grammar.
Course objectives include: i) to understand what is meant by the structure of language, ii) to examine linguistic facts discerned to be structural, iii) to appreciate conceptual/theoretical necessities to account for them (e.g., diverse developments from Generative to Minimalism), iv) to have a grasp of the idea of universal grammar.
Topics include linguistics and syntax, ingredients of structure: linearity and hierarchy, syntactic categories, words to phrases, two kinds of merge: substitution and adjunction (external or internal), introduction to P-markers, various structural relations (Binding Theory), complement vs. adjunct (and specifier), covert elements: trace vs. empty categories (PRO/pro), movement and interpretation: 1. grammatical functions 2. thematic roles 3. displacement (overt movement vs. covert movement like QR), and transformation: substitution and ellipsis.
