Appetitive aggression in former combatants--derived from the ongoing conflict in DR Congo

Soldiers and combatants often report that committing violence can be appealing, fascinating and exciting (Elbert, Weierstall, & Schauer, 2010). This appetite for aggression was investigated in a sample of 224 former combatants from different armed groups and forces in eastern DRC. In a semistructured interview they were questioned about their military history, exposure to violence and perpetrated violence. Appetitive aggression was assessed with a 15-item-scale (Weierstall & Elbert, 2011), which was successfully implemented in comparable samples (Weierstall, Schalinski, Crombach, Hecker, & Elbert, submitted for publication). A sequential multiple regression was conducted to determine possible predictors of appetitive aggression. Perpetrated violence types, recruitment type, and joining as a child were significant predictors and explained 26% of the variability in appetitive aggression. Duration or military rank within the armed group and exposure to violence did not play a significant role. Thus, combatants reporting high levels of appetitive aggression are characterized by perpetrating a high number of violent acts, joining armed groups on their own accord and as children. Joining an armed group on one's own accord indicates pre-existing appetitive aggression. However, joining young and perpetrating violence on a regular basis seem to intensify the appetite for aggression.     

The role of discourses in governing forests to combat climate change

Reducing emissions from forest degradation and deforestation, conserving and enhancing forest carbon stocks, and sustainably managing forests (REDD+) has emerged as one of the most anticipated climate change mitigation tools. This paper aims to understand and identify the underlying discourses that have dominated the emergence of REDD+, by identifying the key story lines in the policy and academic debates on REDD+. As such, this paper takes a step away from the “fine-tuning” of policy recommendations and instead studies REDD+ from a more theoretical approach with the intent to provide a critical analysis of the ideational structures that shape the policies that have emerged around REDD+. The analysis shows that ecological modernization and its accompanying story lines constitute a dominant notion of REDD+ as being able to manage the complexities of forest in a synergetic way, combining cost-efficient and effective mitigation with sustainable development. The paper also identifies the critical counter discourse of civic environmentalism, which criticizes this notion of REDD+ and instead promotes issues such as equity, the importance of local knowledge, and the participatory process. It argues that reducing deforestation involves trade-offs between economic, ecological, and social dimensions, also arguing that REDD+ fits overwhelmingly with the interest of the global North.     

Agilität als Chance für einen neuen Anlauf zum demokratischen Unternehmen?

There has been a long-standing discussion since the 1980s about the question whether new production models harbor a potential for extended employee participation and involvement, in most cases with disillusioning results. This paper is concerned with so called “agile methods”, which play an important part in the area of knowledge work in the course of the digital transformation. On the basis of two case studies from software development and industrial R&D, the paper examines the concrete implementation of these methods and the employees’ perspective upon them and their consequences. The result is that agile methods present a potential for extended employee participation and involvement; however, the realization of this potential depends on the concrete way how the agile concept of “empowerment” is implemented.     

The impact of environmental interest groups in international negotiations: Do ENGOs induce stronger environmental commitments?

Although there is a substantial amount of research that studies how environmental interest groups/non-governmental organizations (ENGOs) influence international environmental negotiations, both the theoretical work and the empirical evidence were not yet able to answer comprehensively if this makes it more likely that states, in turn, commit to stronger environmental agreements. This article seeks to contribute to clarifying this. First, the authors argue that a higher degree of ENGO access to official negotiations and a larger number of ENGOs actively participating during bargaining processes can facilitate outcomes of environmental negotiations. The authors then analyze quantitative data on international environmental regimes and their members’ commitment levels from 1946 to 1998 and obtain robust support for their claims. However, the rationale on the introduced explanatory factors also implies that the impact of ENGO access on states’ commitment levels should vary conditional on the number of ENGOs actively participating. The paper finds evidence for such an interaction, although the results go against our expectations.     

Sequencing of remedies in sales law

This paper analyzes the effects of different sequences of remedies on the incentives of sellers to invest in product quality and on the probability of contract termination. For most European jurisdictions, Directive 1999/44/EC on the sale of consumer goods and its subsequent implementation into national law resulted in a substantial change in the remedies available to the consumer if a product proves deficient. Despite the purpose of the directive to harmonize national legislation, sales laws still differ significantly among member states. The analysis uses a stylized model to compare the pertinent features of two prototypical legal regimes that can be found after the directive’s implementation. The pivotal difference between the respective regimes lies in the sequence of remedies. We show that it is possible that investment incentives and the probability that contractual relationships initiated will be completed may be larger under either legal regime. Despite the general case’s ambiguity, we establish that the cancelation probability is typically lower if sales law limits buyers initial choice of remedies to subsequent performance. Our analysis indicates that the EC’s harmonization target has been missed. With regard to social optimality, we detail under which conditions it is desirable to provide an institutional framework that allows total seller investment to be split between an initial and an incremental input.
