Hybrids,materiality, and black boxes: Concepts of actor‐network theory in data journalism research

Actor‐Network Theory (ANT) vocabulary offers meaningful sensibilities for explorations of data‐driven newswork. Concepts of hybrids, materiality, and black boxes are increasingly mentioned across digital journalism studies and appear to be particularly constructive to examine the relations between data, computation, and journalism practice, epistemology, reflexivity, and journalistic artefacts. After outlining central concepts of ANT, this literature review provides an overview of research agendas that propose sociotechnical dimensions, followed by a structured review of findings generated through ANT‐informed explorations of data journalism. In a closing summary, presented findings and limitations of ANT are discussed.     

Multiple Hypothesis Testing for Variable Selection

We propose two new procedures based on multiple hypothesis testing for correct support estimation in high‐dimensional sparse linear models. We conclusively prove that both procedures are powerful and do not require the sample size to be large. The first procedure tackles the atypical setting of ordered variable selection through an extension of a testing procedure previously developed in the context of a linear hypothesis. The second procedure is the main contribution of this paper. It enables data analysts to perform support estimation in the general high‐dimensional framework of non‐ordered variable selection. A thorough simulation study and applications to real datasets using the R package mht shows that our non‐ordered variable procedure produces excellent results in terms of correct support estimation as well as in terms of mean square errors and false discovery rate, when compared to common methods such as the Lasso, the SCAD penalty, forward regression or the false discovery rate procedure (FDR).

IMAGE AND MISREPORTING

In this paper we analyze how image utility can lead to misreporting of private information in contexts where truthful reports maximize monetary outcomes. In a controlled experiment, subjects go through a series of quiz questions and subsequently report a performance measure. We vary whether reports are made to an audience or not. In an additional feedback treatment, reports are also stated to an audience and afterwards the experimenter publicly verifies whether reports were correct. We find that in the audience treatment, stated reports are significantly higher relative to the private treatment as well as the feedback treatment. Our findings suggest that overconfident appearance might be a consequence of social approval seeking.     

Gentrifizierung in Wien, Chicago und Mexiko Stadt

The lack of comparative gentrification research is regularly addressed by the scientific community. Despite the vast amount of isolated case-studies from different urban contexts, there are only few comparisons of gentrified neighborhoods on a global level. It is hypothesized that to a large extent the lack of international comparisons is based on the limits of quantitative secondary data. Therefore, a qualitative research project was designed to develop an analytical scheme of categories. An actor-analysis was conducted in three neighborhoods in Vienna, Chicago and Mexico City. The semi-structured interviews were analyzed in a qualitative content analysis and then linked to the theoretical gentrification-framework. The result, an analytical scheme of 14 categories, provides a new approach to face the significant lack of international comparisons.     

Trade openness and income inequality: New empirical evidence

We examine how trade openness influences income inequality within countries. The sample includes 139 countries over the period 1970–2014. We employ predicted openness as instrument to deal with the endogeneity of trade openness. The effect of trade openness on income inequality differs across countries. Trade openness tends to disproportionately benefit the relative income shares of the very poor, but not necessarily all poor, in emerging and developing economies. In most advanced economies, trade openness increased income inequality, an effect that is driven by outliers. Our results suggest a strong effect of trade openness on inequality in China and transition countries.     

Vom Vier-Augen-Prinzip zum Zwei-Fronten-Krieg

According to the German Federal Ministry of Economic Affairs and Technology 25 % of all start-ups fail within their first three years. A third of the team managed start-ups fail not because of classical management errors but due to conflicts within the management team. This article aims to pinpoint the reasons behind team conflicts that jeopardize corporations and to illustrate their course by utilizing the psychodynamic concept of collusion relationship (Jürg Willi), adapted from couple therapy. Using anonymized cases, the article will classify characteristic types of collusion and describe possible ways out of these conflicts.     

Die Verbreitung moderner Managementkonzepte im Mittelstand

Within existing studies on the diffusion of modern management concepts, such as Lean Management, Business Process Reengineering or Shareholder Value Management, small and medium-sized enterprises are frequently examined as a homogeneous group of hesitant adopters. Differences among small and medium-sized companies with regard to concept adoption can thus hardly be explained by referring to existing research. In this paper, we argue that differences in adoption patterns of modern management concepts across small medium-sized companies can be explained on the basis of their resource endowment and embedment in different social environments. We thereby employ central arguments from organizational diffusion theory. Based on a multivariate analysis of online-survey data on the diffusion of 22 modern management concepts among 272 German SMEs, our results show that adoption decisions are mainly based on relationships to local organizational environments, whereas concept awareness can be best explained by media-exposure.     

The impact of life stage and societal culture on subordinate influence ethics: A study of Brazil,China, Germany,and the U.S.

In this paper, we investigate the effects of societal values and life stage on subordinate influence ethics. Based on the evolving crossvergence theory of macro-level predictors of values evolution, we demonstrate the applicability of crossvergence theory in the micro-level context. Furthermore, our study provides the first empirical multi-level analysis of influence ethics utilizing a multiple-country sample. Thus, we illustrate how the breath of crossvergence can be expanded to provide a multi-level theoretical foundation of values and behavior evolution across cultures. Specifically, we integrate micro-level life stage theory and macro-level societal culture theory to concurrently assess the contributions of each theory in explaining subordinate influence ethics across the diverse societies of Brazil, China, Germany and the U.S. Consistent with previous research, we found significant societal differences in influence ethics. However, we also found that life stage theory played a significant role in understanding influence ethics. Thus, our findings expand the crossvergence perspective on societal change, indicating that key micro-level predictors (e.g., life stage) should be included in cross-cultural research.
