Qualitative Comparative Analysis (QCA)

Institution: see Organisers & Supporters

Programme of study: International Research Workshop

Contents: Since the publication of the seminal work “The Comparative Method” by Charles Ragin in 1987, set-theoretic methods and especially Qualitative Comparative Analysis (QCA) have become a common research strategy in the social sciences. Set-theoretic methods analyse cases with regard to the identification of sufficient and necessary conditions and assume set relations to be equifinal, conjunctural and asymmetric. Not least since so-called fuzzy sets have been introduced to the method, there has been a rising interest in QCA as a welcome alternative to both small-n case studies and large-n statistical analyses. In short, QCA is recommended if ‘if…then’ hypotheses are analysed; if the goal is to derive sufficient and necessary conditions; if a comparison is planned; and if there is a mid-sized number of cases (between 10 and 60+).

The course offers a comprehensive introduction to QCA and is both conceptually and technically oriented. It starts off with an overview of the basics of set theory and demarcates QCA as a case-oriented method from both the quantitative and the interpretive-qualitative research paradigm. Through the notion of necessary and sufficient conditions and of truth tables, the single elements are built into the Truth Table Algorithm. However, this algorithm is not free of problems. Therefore, some pitfalls and strategies on how to overcome them are presented. On the third day, the software tool fsQCA will be introduced and applied to published studies.

Requirement of students: No prior knowledge is required. We will use the software fsQCA2.5 which can be downloaded at www.fsqca.com.

Multi-level Modelling with R

Institution: see Organisers & Supporters

Programme of study: International Research Workshop

Lecturer: Dr. Daniel Lüdecke (UKE Hamburg)

Date: see Workshop Programme

Max. number of participants: 20

Credit Points: 5 CP for participating in the whole IRWS

Language of instruction: English

Contents: The course teaches how to fit multilevel regression models with the statistical programming language R. First, simple (generalized) linear regression models are introduced to show important basic principles of modelling, like simple regression, interaction terms, non-linear relationships between predictors and outcome (polynomial and spline terms). Later, the application of these principles in a multilevel framework are demonstrated. Furthermore, graphical representation of complex mixed models is covered that help communicate complicated models in a simple way even for a broad audience that is less familiar with such modelling techniques. Successful participation requires basic knowledge of regression modelling techniques. Students are encouraged to bring their own laptops with the free software R (www.r-project.org/) and RStudio (www.rstudio.com/) installed. All source code to run the examples is provided in preparation to the course.

Requirements: Basic knowledge of regression modelling (familiarity with terms like dependent and independent variables, linear and logistic regression, estimate, …)

Analysing Panel and Spatial Data

Institution: see Organisers & Supporters

Programme of study: International Research Workshop

Lecturer: Assoc. Prof. Dr. Timo Friedel Mitze (University of Southern Denmark)

Date: see Workshop Programme

Max. number of participants: 20

Credit Points: 5 CP for participating in the whole IRWS

Language of instruction: English

Contents: The course is divided into two modules:

Part 1) Panel Data Analysis: The first module of the course is organized as a (basic!) introduction to the use of panel data in the different fields of business and social sciences. It is not meant as an expert course in advanced panel data modelling. The main goal is thus to provide insights into why and when applied researchers can benefit from working with panel data, i.e. the combination of cross-sectional and time-series data. The course provides course participants with an overview of the different types of (micro and macro) models that are available for panel data estimation and shows how to properly estimate these models with the help of the statistical software package STATA. Building on these basics, an outlook on more advanced panel data models will be given.

Part 2): Spatial Data Analysis: In the second module course participants will learn to use graphical and statistical tools to visualize and estimate models, in which spatial interaction places an important role. Besides presenting the general logic of spatial modeling approaches, 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, different research settings in business and social sciences are outlined, which may call for the explicit use of spatial estimation techniques, for instance, in order to identify the importance of network and neighborhood effects. This is followed by some practical applications on how to measure and visualize the degree of spatial dependence in variables. The module then introduces course participants into the field of spatial econometrics and students can work with hands-on applications on the basis of different data sets. Finally, a link to spatial panel data models will be given to close the course.

Course Tools: Please bring your laptop computer. STATA can be installed in the beginning of the IRWS. Licenses will be provided. Datasets and STATA ado-files will be provided ahead of the course and should be installed on the participants’ computers. Introductory readings will be provided to registered participants approx. 4-6 weeks ahead of the course (see examples).

Basic requirements: Basic knowledge in econometrics; basic knowledge in STATA (e.g. online tutorial: https://www.youtube.com/watch?v=QaI_a_l2jqo)

Contents: By one widely held conception, Philosophy of Science is the attempt to understand the meaning, method, and logical structure of science by means of a logical and methodological analysis of the aims, methods, criteria, concepts, laws, and theories of science. It is thus an attempt to get a clear understanding of what science is and what is not. The major goal of this course is to provide students that understanding.

We would like to stress that this is an introductory course in Philosophy of Science. Our principles of selection of the topics included have been these: The selection should be intrinsically interesting. It should be relevant and comprehensible to a beginning student. It should serve to provoke discussion and criticism. We have also tried to relate the topics to current philosophical and methodological debates in the management area.

Lecturer: Andrea Schäfer (SOCIUM/Universität Bremen)

Date: see Workshop Programme

Max. number of participants: 20

Credit Points: 5 CP for participating in the whole IRWS

Language of instruction: English

Contents: The goal of this course is to introduce you to the topic of survival (or time to event) analysis and describes selected methods used for modelling and evaluating survival data. General statistical concepts and methods discussed in this course include survival and hazard functions, Kaplan-Meier estimator and graph and Cox proportional hazards model. Accordingly, we will explore the different types of censoring and truncation and, discover the properties of the survival and hazard function. You will learn the derivation and use of Kaplan-Meier (KM) non-parametric estimates and learn how to plot the KM and test for differences between groups. Further, we explore the motivation, strength and limits of Cox’s semi-parametric proportional hazard model and know how to fit the model. For our computer sessions we will be using a sample of the SOEP (Socio-economic Panel) data set. The course requires participants to use Stata to analyse survival analysis data.

In this course, you will learn about:

  • The goal, problem and strengths of survival analysis
  • Differences of survival analysis methods
  • Censoring and truncation (concepts and types)
  • The distribution of failure times (functions, rates and ratio, data layout, descriptive statistics)
  • Basics of non-parametric analysis (estimating Kaplan Meier estimator and comparing curves, graphing)
  • Basics of semi-parametric analysis (model definition and features, understanding and estimating Cox’s PH model)

Required: intermediate statistical knowledge, basic Stata skills

ReMaT – Research management training for early-stage researchers

A ReMaT workshop – Research management training for early-stage researchers – will take place in Hamburg on 18th and 19th November 2019. The workshop is designed for early-stage researchers in engineering and natural sciences, particularly PhD candidates from the 2nd year onwards. The idea of European networking is very much embedded in the concept, and we encourage participation from many different countries at the workshop.

ReMaT is an interactive, intensive workshop providing an introduction to research management. It involves two international trainers and is held in English. The modules of the workshop cover exploitation of knowledge and entrepreneurship, acquisition of grants, intellectual property rights and the management of interdisciplinary projects. They are delivered in such a way that it challenges participants to consider different perspectives on how they might use their PhD education in a variety of career paths, and convince others to hire them.

The organiser:
Tutech Innovation GmbH was founded in 1992 as the technology transfer institute for the Hamburg University of Technology. We are offering services regarding participation in EU funded programmes especially for publicly funded universities and SMEs. TUTECH ACADEMY workshops on technology transfer and innovation and research management equip participants from research and business with the right skill sets to do new work in their fields. Tutech Innovation GmbH has considerable experience in coaching researchers from a wide variety of backgrounds, disciplines and experience as well as nurturing those doing PhDs, participating in graduate schools or in the early stages of career development.

Introduction to Data Mining and Quantitative Text Analysis with R

Institution: see Organisers & Supporters

Programme of study: International Research Workshop

Lecturer: Pascal Jürgens (Johannes Gutenberg-University Mainz)

Date: see Workshop Programme

Max. number of participants: 15

Credit Points: 5 CP for participating in the whole IRWS

Language of instruction: English

Contents: This course offers a simple and pragmatic introduction into the quantitative analysis of textual data in R and simple data mining tasks. There are four main themes: 1) Data logistics: Data preparation is a crucial task that often takes a lot of work and significantly influences results. We will therefore spend some time to understand how to load, prune, re-arrange and represent textual datasets. 2) Text analysis tools: This section will introduce methods for answering research questions through quantitative approaches, such as word frequency analysis, topic modeling and select semantic methods (if there is a specific application participants are particularly interested in, they are encouraged to reach out in advance to make sure it will be covered). 3) Data mining: Part three covers simple but powerful types of machine learning including clustering and linear models. More advanced methods (such as neural networks) will not be covered in DIY-exercises, although we may cover the basic mechanisms if time permits. 4) Rigor: The quantitative methods at hand are particularly sensitive to conceptual and empirical variation. We will therefore take apart some of our example models in order to understand how and when they fail.

A basic familiarity with the R environment and R Studio is required; introductory material will be provided in advance so that participants can read up and gain the necessary skill level before taking part. Participants should bring a laptop with R Studio pre-installed (www.rstudio.com).
