ALLBUS (Allgemeine Bevölkerungsumfrage der Sozialwissenschaften – German General Social Survey (GGSS)) is one of the foremost survey programs in Germany. It has been institutionalized as a part of GESIS – Leibniz Institute for the Social Sciences. The prototype for similar national data generation programs is the American General Social Survey (GSS).

Since 1980, ALLBUS/GGSS has provided a series of representative cross-sectional samples drawn from the adult population in Germany. These biennial surveys include partly replicative and partly innovative question modules and added value data for analyses of social structure, attitudes, values, and behavior in Germany. Moreover, users may find various possibilities for international comparisons. There are 19 currently available ALLBUS/GGSS surveys (1980-2012) with a total of 57,723 respondents. A large part of the documentation has been translated into English.
In its first part the course gives an overview of the project as such, basic sampling procedures, various question modules, and recent activities of the ALLBUS Research Data Center. The second part comprises hands-on exercises of chosen data. The calculations will be done primarily using SPSS-syntax. Participants should have fundamental knowledge in data handling, in statistical data analysis and in using programs like SPSS via syntax.

This course will familiarize students with basic concepts in social network analysis. The focus will be on two topics: social networks as resources, and social networks as structure. The resource approach focuses on the social embeddedness of individual action and can be investigated using standard statistical tools. Investigating social networks as structure, however, requires special network analysis software (Pajek). Centrality and prestige in networks, subgroup analysis, and roles and positions will be analyzed.

Analysing Panel Data/Advanced Econometrics

Institution: see Organisers & Acknowledgements

Program of study: International Research Workshop

Lecturer: Nisar Ahmad, Timo Friedel Mitze & Torben Dall Schmidt (University of Southern Denmark)

Date:

03.10.2013, 09:30 – 17:30

Room: n.s.

Max. number of participants: 20

Semester periods per week: n.s.

Credit Points: 5 CP for participating in the whole IRWS

Language of instruction: English

Contents:

The course is basically divided into two parts: Part 1) Analyzing panel data. Part 2) Spatial Data Analysis

Part 1): Structure of the Panel Data:
This part of the course is an introduction to the panel data analysis and it provides some insights into why we use panel data. What kinds of models are available for panel data and how do we estimate such models. It also covers some extensions to the basic panel data models and finally there will be a session where you will learn how to estimate panel data using STATA.

Part 2): Spatial Data Analysis
In research fields such as regional science, quantitative sociology and business analysis as well as real estate, labor and health economics (to name just a few), researchers are increasingly aware of the fact that “space matters”. Thus, the goal of this workshop module is to equip participants with the basic knowledge about methods and tools currently available in “spatial statistics” and “spatial econometrics”. Besides presenting the general logic and theoretical foundations of these modeling approaches for variables with an explicit geographical context, a strong focus lies on illustrating the potential for applied work with these tools in the software package STATA. The module is structured as follows: After a brief introduction of the historical evolution of spatial data analysis, different research settings in economics and related research fields are outlined, which may call for the explicit use of spatial estimation techniques, for instance, in order to identify the importance of space-time autocorrelations and neighboring effects (spatial spillovers). Following this introduction, the concept of the spatial weighting matrix is introduced and statistical approaches to measure and visualize the degree of spatial dependence for a variable under study are presented. Moving from univariate to multivariate modeling techniques, the course then derives estimation techniques used in the field of spatial econometrics and links this theoretical knowledge with hands-on applications for different spatial datasets. Finally, to serve as an outlook on future research possibilities, state-of-the-art concepts such as spatial panel data models and spatial limited dependent variable models will be presented.

Datasets and STATA ado-files will be provided ahead of the course and should be installed on the participants’ computers.

Vignette experiments provide “… short descriptions of a person or a social situation which contain precise references to what are thought to be (…) important factors in decision-making or judgment-making processes of the respondents…” (Alexander & Becker, 1978, 94). Within the description, the independent variables are systematically varied by the experimenter (Beck & Opp, 2001). Then the targeted variable, for instance behavioral intentions, is asked about. Provided the vignettes are realistic, the number of factors chosen should mirror the complexity of the decision environment decision makers are normally confronted with (Rossi & Anderson, 1982). Hence, a vignette experiment mimics the outcomes of “typical” decisions. Participants are led to weigh the significance of single characteristics to arrive at an overall preference for one alternative. As in reality, the participants are involved in a trade-off. Such a capacity to deal with the complexity of real decision making gives the design external validity while retaining the internal validity. provided through the experimental features of the factorial survey (Taylor, 2006).

In short, vignette analyses are based on the following three concepts (Teichert, 2001): (1) Every situation consists of a bundle of characteristics. (2) Every participant makes an individual evaluation of the benefits of various combinations of characteristics. (3) The combination of the benefits of various characteristics provides the relative overall benefit to an individual.

The workshop aims at establishing a theoretical and practical understanding about vignette experiments. We will discuss the method by using concrete examples of my former research (Rost & Weibel, 2012; Weibel, Rost, & Osterloh, 2010).

Current research ideas, projects or materials of participants can be considered and discussed in case of interest.

1. What is covered in the workshop? What will you learn?

This interdisciplinary workshop introduces you to selected fundamental theories, concepts, methods and applications for bringing together text analysis and network analysis. You will learn how to conduct data analysis at the nexus of these areas in an informed, systematic and efficient fashion, and how to:

  • Construct semantic networks and socio-technical networks from unstructured, natural language text data.
  • Visualize and analyze network data.
  • Interpret network analysis results.

Throughout the workshop, we will discuss practical applications from the academic, administrative and business domain. At the end of the workshop, you will be able to design and conduct research projects for scholarly and commercial use in these fields.

Semantic networks are structured representations of information and knowledge. Socio-technical networks represent interactions between social agents, infrastructures and information. The functioning and dynamics of these networks involve the continuous production, processing and flow of information. This information is often available as text data, and can serve as a single or complementary source of information about networks. Examples for data sources include news wire data, scientific information such as publications and patents, communication data such as conversations transcripts and emails, self-presentations such as mission statements and annual reports, and social media data such as tweets and wikis. Using text data to construct or enhance network data has been used to answer questions such as:

  • Who is talking to whom, and about what?
  • What are the mental models of individuals or groups about certain topics?
  • How do memes and innovations emerge and spread in society and online?
  • Who are the key entities in a network?
  • What benefits and risks result from an observed network structure for an organization and its wider context?

The main component of this workshop is to teach to you practical, hands-on skills in working with text analysis and network analysis tools. You will perform basic natural language processing techniques on the lexical, syntactic and semantic level including:

  • Pre-process texts with techniques such as reference resolution, stemming and parts of speech tagging.
  • Identify salient concepts and themes from single documents and entire text collections.
  • Create and apply codebooks, which are also known as dictionaries or thesauri.
  • Locate and classify entities that can serve as nodes for networks. We will move beyond the classic set of entity classes (people, organizations, locations) to also consider other classes that relevant for studying social processes and culture, e.g. tasks, resources and knowledge.
  • Relation Extraction, linking entities into edges based on various criteria.

You will also perform basic network analysis techniques, including:

  • Manipulate and visualize network data.
  • Compute basic network metrics on the graph and node level.
  • Identify meaningful groups and clusters of nodes.

Going from texts to networks involves some principles and strategies originating from computer science that are not only applicable to the task at hand, but to a wide range of problems. These principles and strategies are referred to as “Computational Thinking” – a basic skill like reading, writing and arithmetic that is crucial for solving problems and understanding human behavior across fields (Wing 2006). In this workshop, you are introduced to Computational Thinking and practice applying this way of thinking.

3. Who should attend?

This is an interdisciplinary and interactive workshop designed to benefit from the participation of attendants from different backgrounds. The material, exercises and mode of delivery are suitable for researchers and practitioners alike. No specific prior knowledge or computational skills are required. The delivery is driven towards forming an understanding of fundamental concepts and gaining hands-on experience with text analysis and network analysis methods and tools.

4. What to bring to the workshop?

Software: Prior to the workshop, we will send an email to confirmed participants with links to the software tools that we will use for the workshop. You are invited to bring a laptop to the workshop. If you cannot bring a laptop you will still fully benefit from the workshop as we screen-project all live walk-through exercises. At the workshop, we will provide you with a tutorial document and further learning resources.

Data: You can work with the sample data that we provide you with and/ or bring your own data. If you bring your own text data, we recommend a sample of not more than 20 text documents of less than two pages in length, and network data with not more than 200 nodes. The tools we use scale up to larger data sets, but large-scale data might not be practical for training purposes.

5. Readings

Prior to the workshop, we ask people to go read the following overviews on the concepts and methods addressed in the workshop (copies of both papers will be emailed to confirmed participants prior to the workshop):

    The Institute for Employment Research in Nuremberg has available a wealth of micro data on the German labor market and offers access to it in its Research Data Center (FDZ). The course’s goal is to arouse the participants’ interest in FDZ data and to guide their first steps into analyzing them. The focus will be on two large administrative data sets, namely the Sample of Integrated Employment Biographies (SIAB) and the Establishment History Panel (BHP). In hands-on sessions we will explore, cleanse and prepare the data, calculate durations, and implement simple imputation procedures. The course will also cover in some detail the IAB Establishment Panel, the FDZ’s most important survey data set, and the Linked Employer-Employee Dataset of the IAB (LIAB); other FDZ data will also be presented, but rather cursorily.
