Abstract

 

An introduction to network concepts, analysis, and application. Emphasis is on mastery and use of general concepts, techniques, and the use of UCINET and related software packages. The broad usefulness of network analysis is illustrated by examples of personal-acquaintance networks and cliques, connections among urban organizations, patterns of communication and information flows, transmission of disease, kinship ties, trade and economic webs among countries, and influence and authority relationships.

 

Overview

 

Some of the most innovative and useful research and evaluation techniques today in both Europe and the U.S. involve analysis of personal and organizational networks. Individuals, groups, and organizations are tied together by interaction patterns, common members, communication exchanges, and resource flows. Analysis of these complex patterns requires specialized research methods and technologies. The software package UCINET gives us a powerful way of doing sophisticated network analysis, allowing precise measurements of network characteristics. We also have available programs (KrackPlot, Pajek) that map networks for visual display and analysis. Network analytical techniques treat data as relational in character, and thus the methods can examine and explain phenomena that that either cannot be handled at all, or poorly, by conventional means of data analysis such as correlation and regression. Thus the approach can add unique ways of understanding a great variety of issues.  For example, we may examine the role that personal and professional networks play in job searches, analyze power structures in communities and urban areas, determine how networks of friends are linked into "cliques," study how medical knowledge diffuses through webs of doctors, investigate international trade patterns, and much more. As but one recent and intriguing example, the FBI is now using network techniques to study criminal conspiracies.

 

Topics in this Course

 

·       overview of the use of network analysis in recent research literature

·       applications of network analysis to practical problems and issues

·       theory and measurement of network concepts such as connectedness, density, centralization, paths and walks, reach, transitivity, direction, distance, blocks, flows, etc.

·       introduction to UCINET capabilities

·       visual plotting and analysis of networks using KrackPlot and Pajek

·       centrality analysis

·       clique analysis

·       structural equivalence and positional analysis

·       analysis of data on ties among more than 150 organizations and nearly 4000 individuals in Louisville

 

Goals and Objectives

 

 It is expected that students have at least some familiarity with a word processing program and computers.  Completion of the course will permit students to use network theories and tools in the practical understanding and study of a wide range of social policy issues.  It should be kept in mind that the field of network analysis is vast, complex, and rapidly growing.  This course is intended to serve as a GENERAL introduction to social network analysis, not a comprehensive, in-depth coverage of all aspects of the subject.

 

For graduate students: In addition to the other requirements, graduate students will complete an original network analysis research project using relational data.  The topic will be decided in consultation with the instructor.

 


Reading Materials and Resources

The following two publications are required for the course.  They are in Gray’s Bookstore.

1.  SOCIAL NETWORK ANALYSIS, Stanley Wasserman and Katherine Faust, Cambridge University Press, 1994.

2.  The UCINET software program.  You will each have your own student version of this network analysis program to run on the (IBM) computer of your choice.

3.  A CLASSPAK of readings (contains all reading assignments outside of Wasserman and Faust).

Requirements and Grading

You will need to have at least some knowledge of how to use a personal computer.  The UCINET program is fairly easy to use, but will require that you can do simple keyboard operations, create, save, and print files, and perhaps use a few features of DOS.

Prerequisites: Junior, Senior, or Graduate standing or consent of instructor.

Undergraduate students: Your grade for the seminar will be based upon:

1.  Weekly Assignments (20 percent)

2.  Class Participation (20 percent)

3.  Exams (a total of four, 15 percent each = 60 percent)

Graduate students: Your grade for the seminar will be based upon:

1.  Weekly Assignments (10 percent)

2.  Class Participation (10 percent)

3.  Exams (a total of four, 10 percent each = 40 percent)

4.  Graduate Research Project (40 percent)

Weekly Assignments  Generally, you will be assigned exercises to be due the next class meeting.  You will hand in your Weekly Assignments at the start of each class period. The assignments will ask you to answer theoretical questions, address points raised in the readings or in class, create data files, process data using UCINET, and interpret the results.  I will grade the assignments and return them to you within a week or less. It is important to hand in all assignments on time, since the content of the class builds on itself.  Do not fall behind.

Class Participation  I will assign a class participation grade for the semester based on my judgement of how actively and thoughtfully you took part.  This grade will be based upon such things as:

1.  completing the readings on time and generally being prepared for each class

2.  demonstrating involvement with and understanding of the material

3.  speaking up in class, discussing issues

4.  asking questions and responding to questions

5.  leading discussions, when requested

Exams.  There will four Exams on the dates indicated.  Exams will cover the readings, as well as network theory, applications, and aspects of the operation of UCINET.

Graduate Research Project.  Graduate students will be required to analyze and write a report on a large dataset that I will distribute near the end of the semester.  You will be expected to use all (or nearly all) of the analytical techniques we will cover in the semester.  This includes applying various techniques implemented in UCINET, as well as selective use of SPSS (if appropriate).  Graphical analysis may involve the use of UCINET, Pajek, or Krackplot.  The written portion of the project will require you to make sense of and explain the data and the analysis.  I will have more to say about the project in class.  It will be due on the last day of the Final Exam Period.

For undergraduate students, the grading scale will be:

A   90-100

B   80-89

C   70-79

D   60-69

F   < 60

For graduate students, the grading scale will be:

A+  97-100
