Objectives. Several studies have shown that perseverative, worrisome thoughts are prospectively related to subjective health complaints (SHC) and that a short worry
postponement intervention can decrease these complaints. As SHC and worry are prevalent and costly, we tested whether the intervention can be offered online to reduce
these complaints in the general population.
Design. Arandomized parallel-group trial was conducted with self-selected participants from the general population.
Methods. Via the research website, 996 participants were instructed to register their worrying for 6 consecutive days. The intervention group was instructed to postpone
worry to a special 30-min period in the early evening. The Subjective Health Complaints inventory, as administered before and after the intervention, and daily worry frequency
and duration were considered the primary outcomes.
Results. Three hundred and sixty-one participants completed the study. Contrary to our expectation, the registration group (n = 188) did not differ from the intervention
group (n = 163) in SHC (eta-p = .000, CI [0.000–0.003]), or in worry frequency or duration. Nevertheless, the different worry parameters were moderately related to SHC
(r between .238 and .340, p ? .001).
Conclusions. In contrast to previous studies using pen-and-pencil versions of the worry postponement intervention, this study suggests that a direct online implementation was
not effective in reducing SHC and worry. Overall, participants had high trait worry levels and reported difficulty with postponing worrying. Reducing SHC and worries via the
Internet might require more elaborate interventions that better incorporate the advantages of delivering interventions online

Ten Emotions Examined Through Videoclips: Boredom, Revulsion, Sadness, Pain, Fear, Haste, Aggression, Geborgenheit (something like Comfort), Joy, Equanimity
No full textArt and science often face each other as antipodes in the academic world. They differ fundamentally in their methodical approach. Artistic work aims at the precise analysis and understanding of subjective thoughts and feelings. In contrast, science is theory-driven and focused on objective findings and generalizable results. This archive was created to bring both into discourse.
It includes:
- A description of a an artistic-research process that explored the understanding of ten emotions (Zeißig, A. (2018). The Creative Act as a Mode of Research: Ten Emotions - Ten Films. Weinböhla: edition neuhaus. http://dx.doi.org/10.23668/psycharchives.4852).
- A database of ten developed videos exploring the emotions of boredom, revulsion, sadness, pain, fear, haste, aggression, comfort, joy and equanimity (Zeißig, A. (2018). Database of Ten Emotions - Ten Films. Weinböhla: edition neuhaus. http://dx.doi.org/10.23668/psycharchives.4851).
- The result of a first empirical study to investigate the induction of intended emotions (Zeißig, A. (2019-07-17). Ten Emotions - Ten Films [Poster presentation]. International Society for Research on Emotion Conference, University of Amsterdam. PsychArchives. http://dx.doi.org/10.23668/psycharchives.4853).
The project is looking for interested researchers and collaborations to further test the videos. Since the videos are language-free and free of culture or time specific elements, narration or dramaturgy it would be interesting to cooperate transnationally and international to discuss the development of culture-free emotion induction methods.This is a secondary publication of: Zeißig, A.

The evolution of the innovation network and the technological system in a standard developing organization. The example of cellular telecommunications
No full textStandard developing organizations (SDOs) are voluntary inter-organizational collaborations with the goal to develop jointly compatibility standards for complex modular technological systems. This dissertation examines the evolution of the innovation network and technological system in a SDO with the perspective of complementing micro and macro level. The dissertation is rooted in the multidisciplinary complex system theory and draws on a broad range of literature from management, sociology, biology and physics with the common theme of bipartite network analysis. The innovation network is conceptualized as a bipartite network with ties between organizations and innovations to which they contribute. I show that technical capital, resources in the SDO and their match between organization and innovation, rather than social capital, network position, drive the tie formation in the innovation network. To answer the question of emerging order in an innovation ecology without formal hierarchy I borrow from the literature of ecological mutualistic networks. I show that a nested order emerges based on a parsimonious process of matching resources, that leads to a rather stable system over more than ten years. The evolution of the technological system in the SDO environment departs from the established life cycle model and is best described by a life spiral model with continuously increasing system performance rather than punctuated equilibria. The key distinction to market-based technological evolution is the coordinated and designed development process within the SDO, that allows to introduce new services and change core parts of the system based on architectural knowledge. As a consequence the development process follows a gradual change model with changing tempo. Furthermore the evolution is characterized by simultaneity of innovation types that identifies the SDO as ambidextrous organization with separation of exploitation and exploration on project level. The research context is Third Generation Partnership Project (3GPP) in the cellular telecommunications industry with data from 1992 to 2011.Ph.

Correction to: Exponential stability of impulsive stochastic genetic regulatory networks with time-varying delays and reaction-diffusion
No full textAbstract In the publication of this article (Cao et al. in Adv. Differ. Equ. 2017:307, 2017), there was an error that the author Anke Meyer-Baese was missing. Anke Meyer-Baese contributed towards the methodological design, study concept, the biological interpretation of the parameters of the systems and the writing of the system’s description. Omission is due to an oversight. This has now been included in this erratum
External interventions and the duration of civil wars
No full textThe authors combine an empirical model of external intervention, with a theoretical model of civil war duration. Their empirical model of intervention allows them to analyze civil war duration, using"expected"rather than"actual"external intervention as an explanatory variable in the duration model. Unlike previous studies, they find that external intervention is positively associated with the duration of civil war. They distinguish partial third-party interventions that extend the length of war, from multilateral"peace"operations, which have a mandate to restore peace without taking sides - and which typically take place at war's end, or at least when both sides have agreed to a cease-fire. In a future paper, the authors will examine whether partial third-party interventions - whatever their effect on a war's duration - increase the risk of war's recurrence. If that proves true, then even if interventions reduce the length of civil war, they may do so at the cost of further destabilizing the political system, and sowing the seeds of future rebellion.Children and Youth,Peace&Peacekeeping,Post Conflict Reconstruction,Post Conflict Reconstruction,International Affairs,Post Conflict Reconstruction,Social Conflict and Violence,Peace&Peacekeeping,Post Conflict Reconstruction,International Affairs
Odd and even Maass cusp forms for Hecke triangle groups, and the billiard flow
No full textBy a transfer operator approach to Maass cusp forms and the Selberg zeta function for cofinite Hecke triangle groups, Moller and the present author found a factorization of the Selberg zeta function into a product of Fredholm determinants of transfer-operator-like families: Z(s) = det(1 - L-s(+)) det(1 - L-s(-)). In this article we show that the operator families L-s(+/-) arise as families of transfer operators for the triangle groups underlying the Hecke triangle groups, and that for s is an element of C, Res = 1/2, the operator L-s(+) (respectively L-s(-)) has a 1-eigenfunction if and only if there exists an even (respectively odd) Maass cusp form with eigenvalue s(1 - s). For non-arithmetic Hecke triangle groups, this result provides a new formulation of the Phillips-Sarnak conjecture on non-existence of even Maass cusp forms.Volkswagen Foundatio

Post-conflict private sector development : promoting durable peace : What are the characteristics and short comings of economic development in post-independent, sub-Saharan Africa : examples from Mozambique?
No full textIncludes abstract.In times of war the private sector adapts, often to function informally, and can serve to either perpetuate conflict or to incentivize peace. Accordingly, the private sector is a powerful tool that can be utilized during post-conflict reconstruction to enable sustain- able peace and economic development. After a conflict, in an effort to establish a means of survival outside of the war economy, there is a pressing need for the population to have a means by which to provide a livelihood and productively contribute to society. Establishing sustainable economic exchange and developing social capital between various members of society is one mechanism by which to achieve restorative justice and disincentivize conflict. ...this paper argues for a hybrid approach to private sector development that includes both the investment climate and interventionist methods to disincentivize a return to conflict
