Introduction
I was a lecturer at Bremen University teaching research methods and statistics. Now I work as a data scientist at Deutsche Bahn. I am interested in quantitative data analysis and an R enthusiast. Also, I work a lot with repertory grids. Among other things I develop the Open Source grid software OpenRepGrid (see www.openrepgrid.org).

Description
  • My focus of work are psychological methods, statistical data analysis and data visualization. Here, main interest lies in the analysis of idiographic attribute data, as e.g. generated by the repertory grid technique or free choice profiling.

Conference Paper
Die DB Station&Service AG ist als Eisenbahninfrastrukturunternehmen (EIU) im Rahmen der Leistungs- und Finanzierungsvereinbarung III (LuFV III) dazu aufgefordert, auf wissenschaftlicher Basis einen Ursache-Wirkungs-Zusammenhang (UWZ) zwischen den zur Verfügung stehenden Instandhaltungs- und Investitionsmitteln und der davon beeinflussten erzielbare...
Conference Paper
To find the optimal maintenance policies, the DB Station&Service AG - a railway infrastructure company which manages the majority of the railway stations in Germany - needs to describe the cause-effect-relationship between the funds for maintenance and the quality of the station equipment. To determine the influence of funding on the infrastructure...

The research question we would like to answer with this article is if agile related constructs or personal assessment criteria can be elicited from a personal construct system of employees and leaders by carrying out a repertory grid study in an organisation. The methodology of personal construct psychology was chosen to get an unbiased view of the...
Article
This paper presents and illustrates Interpretive Clustering, an innovative and original method of qualitative analysis of Repertory Grid data. Repertory Grids are a popular and flexible method of research, but they have primarily been used to gather data that are analysed quantitatively. Although many researchers have used Grids more qualitatively,...
Article
Content analysis is a frequently applied technique used to pool the constructs obtained from a set of repertory grid interviews by creating categories containing constructs with similar meanings. In the standard procedure, the constructs are categorized by analyzing only the semantic information given in the construct poles. In a few cases in the l...

Introduction Intercultural competence (IC) is an important skill to be gained from higher education. However, it remains unclear what IC means to students and what factors might influence their definitions of IC. The aim of the current study was to qualitatively assess how students at one higher education institution in the USA define IC and to qua...

Article
The subjective importance of constructs elicited with the repertory grid technique (RGT) has been conjectured to depend on elicitation order. Constructs elicited early in an interview are assumed to be subjectively more important than later ones. For the RGT, this conjecture is based on only one empirical study with a small sample size using person...
Article
Several articles have discussed the effect of variations in the repertory grid procedure on measures derived from the data it generates. Largely unexplored, in contrast, is the effect of a more subtle variation inherent in the grid procedure itself: the specific combination of elements used in a dyad or triad during elicitation. This study investig...
Article
Full-text available
The repertory grid is a psychological data collection technique that is used to elicit qualitative data in the form of attributes as well as quantitative ratings. A common approach for evaluating multiple repertory grid data is sorting the elicited bipolar attributes (so called constructs) into mutually exclusive categories by means of content anal...
Conference Paper
Biplots are a method to visualize multivariate data. They display information about cases and variables of a data set jointly in one single plot. In the field of food science and personal construct psychology, they are frequently applied to visualize the results of idiographic attribute data sets. These types of data emerge from free choice profili...

Fleisch ist für viele Menschen Bestandteil des täglichen Konsums. Es gehört zu einer „richtigen“ Mahlzeit dazu und wird mit Männlichkeit, Stärke und Status assoziiert. In den letzten Jahren verändert sich allerdings die Einstellung der Bevölkerung zum Fleischkonsum. Es wächst die Gruppe derer, die Fleisch bewusster konsumieren oder komplett darauf...

The subjective importance of constructs elicited in repertory grid interviews has been conjectured to depend on elicitation order. Constructs elicited early in the interview are assumed to be more important than later ones. This conjecture is based on few studies using persons as elements and seems to not have been replicated for other topics. Here...
Presentation
Full-text available
The repertory grid is an elicitation technique that is used across various scientific fields. In studies, where a large number of grids are collected, the elicited constructs are frequently submitted to content analysis. This is, for example, a common scenario in market research in order to identify salient topics of a field. In order to prevent sy...
Article
Hierarchical clustering is a common way to analyze repertory grid data, as it allows visual identification of homogeneous groups of elements and constructs. This article explores a bootstrap approach to clustering that additionally allows significance testing of dendrogram structures. Given that the choice of the specific clustering method and dist...
Chapter
Index measures for repertory grid data are a frequently used approach to summarize characteristics of a grid. We can differentiate between measures at the grid level that describe global features of the grid, like e.g. a construct system's complexity, and local measures at the construct level, such as, e.g., the intensity of a construct. Global mea...
Conference Paper
Several papers have discussed the effect of variations in the grid procedure on measures derived from repertory grid data. Largely unexplored in contrast is the effect of a more subtle variation inherent in the grid procedure itself: the choice of specific elements comparisons in the elicitation procedure. This study investigates the differential e...
Conference Paper
The repertory grid is a technique that yields data with idiographic dimensions, i.e. the constructs. Generalized procrustes analysis (GPA) is a technique that can be used to aggregate this type of idiosyncratic data structure. It has been used extensively in the field of sensory research but less often in the field of PCP. At its core, GPA is purel...
Conference Paper
Face-to-face interviews are the traditional way repertory grids are performed while interactive, computer-based methods that work entirely autonomous without an interviewer are not widely spread. In this study we present a novel approach to allow repgrid interviews not only being conducted interactively but also fully automated within an online web...

In the workshop participants are introduced to the OpenRepGrid project. Part of the project is an open source software for the analysis of repertory grid data. The software currently comes in two flavors: As an online analysis tool and as an add-on package for the R program. The workshop gives an introduction to the software, its development philos...

In the workshop participants are introduced to OpenRepGrid, a new Open source software for the analysis of repertory grid data. OpenRepGrid is an add-on package for the R program (see www.r-project.org) and runs on all major operating systems. Over the last decades various grid programs have been developed. The way the production of these progra...

• Purpose The core objective of this paper is to introduce the multiple repertory grid technique as a powerful cognitive mapping methodology to explore and visualize organizational culture. The novel approach is particularly capable of yielding insights into an organization’s central values and the corresponding key stakeholder’s perceptions. In a...

Conference Paper
Slater (1977) outlined that the Euclidean distance as a measure of inter-element similarity cannot readily be used for comparisons across different grids. The reason is that its magnitude depends on the graduation of the rating scale and the number of constructs in a grid. As a remedy, Slater devised an approach to standardizing the Euclidean d...
