Modern societies and organizations have become more complex: physical, personal and informational linkages strongly affect managerial activities in several applicative contexts. This new framework deserves adequate quantitative tools to be properly analyzed. This course will provide PhD students in Management with the basic concepts behind the idea of network, the main measurement tools and techniques needed to analyze information flows in network structures.

This course addresses some classical and more recent advances in the context of network theory. We will analyze the main social network structures, their properties and the basic tools of mathematics of networks. Finally, we will study how information, innovation and opinions spread through networks due to social interactions.
At the end of the course, the student will have acquired knowledges about the basic mathematical tools to deal with networks and social networks, the main measures and metrics related to networks, the concept of centrality and “importance” and their consequence for management studies (for example, the role of hubs and influencers). He/she will learn how to model diffusion of information on networks with applications to opinion dynamics, consensus formation and advice networks.

Students will be able to critically read, analyze, present and discuss academic papers related to the applications of network theory in the field of management.
We expect that students enrolled in the PhD in Management at Ca’ Foscari University already possess basic knowledge of mathematics and statistics. The following is a list of notions that students enrolling in the PhD in Management at Ca’ Foscari University should be familiar with before starting the PhD courses. Knowledge of these concepts could be assessed during the interview.


Mathematics

• Number sets - Powers and their properties - Logarithms and their properties - Equations – Inequalities
• The notion of real function - Graphs of functions – Linear and quadratic functions – Logarithmic and exponential functions
• Derivatives - Rates of change - Increasing/decreasing functions – Convexity and concavity
• Rules for differentiation - Maxima/Minima
• Indefinite integrals - Definite integrals - Improper integrals
• Basics of matrix algebra

Statistics

• Basic notions of probability theory
• Mean, median, variance , standard deviation
• Hypothesis testing
• Correlation (e.g., how to interpret a correlation coefficient)
• Linear Regression (e.g., how to interpret a regression coefficient)
• Types of variables (e.g., continuous, ordinal, categorical, dummy)
• Basic familiarity with computers and productivity software, like excel

Supplementary material and discussion papers will be provided by the instructor.
The evaluation is based on a written exam and on some ongoing activities.
The written exam consists in a set of problems (exercises) related to the program seen in class and in some theoretical questions. Mock-ups will be provided to students during the course. The structure of the ongoing activities will be discussed at the beginning of the course.
Due to the percistency of the current health emergency it is not possible to establish now the precise teaching method adopted for this course. Theoretical concepts and applications will be presented through standard (or in distance) classes. When needed, the analysis of theory and applications will be supported by the use of dedicated software. Students will be encouraged to read, analyze and, finally, discuss in class some academic papers.
Accessibility, Disability and Inclusion.

Accommodation and support services for students with disabilities and students with specific learning impairments Ca’ Foscari abides by Italian Law (Law 17/1999; Law 170/2010) regarding support services and accommodation available to students with disabilities. This includes students with mobility, visual, hearing and other disabilities (Law 17/1999), and specific learning impairments (Law 170/2010). If you have a disability or impairment that requires accommodations (i.e., alternate testing, readers, note takers or interpreters) please contact the Disability and Accessibility Offices in Student Services: disabilita@unive.it.
