We propose a simple agent-based macroeconomic model in which firms hold heterogeneous sales expectations. A firm may either optimistically expect an increase in its sales or pessimistically expect the opposite. Whether a given firm is optimistic or pessimistic depends on macroeconomic conditions and the average mood prevailing within its social/local neighborhood. For instance, the probability of a firm taking an optimistic view increases not only during a boom but also with the number of its optimistic neighbors. We show that such an economy may give rise to co-evolving dynamics between the business cycle and the firms' average sentiment. © IOP Publishing Ltd and Deutsche Physikalische Gesellschaft. Source

Pain Medicine | Year: 2012

The present review summarizes experimental data on age-related changes in pain processing. These data suggest an increase in pain threshold and a decrease in tolerance threshold, which both are dependent on the physical nature of the stressor, as well as a developing deficiency in endogenous pain inhibition, which might be paralleled by an enhanced disposition to central sensitization (stronger temporal summation). These findings are arranged in a model that allows for explaining the two seemingly divergent perspectives: age both dulls the pain sense and increases the prevalence of pain complaints. This model is based on the assumption that both excitatory and inhibitory processes are dampened with age but that the later processes age at a faster rate, leading to increasingly unbalanced pain excitation. © 2012.

MIS Quarterly: Management Information Systems | Year: 2013

This study investigates the role of information systems in stimulating energy-efficient behavior in private households. We present the example of Velix, a web portal designed to motivate customers of a utility company to reduce their electricity consumption. In particular, we consider the effectiveness of goal setting functionality and defaults in influencing energy conservation behavior. For this purpose, we use the web portal as a test of the theoretical propositions underlying its design. Based on data collected from a field experiment with 1,791 electricity consumers, we test hypotheses regarding the structural relations between defaults and goals, the impact of defaults and goals on consumption behavior, and the moderating role of feedback on goal choice. Our results confirm the positive impact of goal setting on energy conservation. We show that default goals lead to statistically significant savings by affecting goal choice. However, if the default goals are set too low or too high with respect to a self-set goal, the defaults will detrimentally affect behavior. We also show that feedback on goal attainment moderates the effect of default goals on goal choice. The results extend the knowledge on goal setting and defaults and have implications for the design of effective energy feedback systems. The study's approach, which combines hypothesis-driven work and design-oriented IS research, could serve as a blueprint for further research endeavors of this kind, particularly with regard to feedback systems based on future smart metering infrastructures.

Journal of Cognition and Development | Year: 2015

This study investigated the longitudinal relation between children's theory of mind and their metacognitive knowledge with a special focus on the impact of language on this relation. Measures of theory-of-mind understanding and metamemory knowledge were assessed in 133 3-year-old children at 4 measurement points separated by half-year intervals. Results revealed a somewhat more pronounced effect of children's early theory of mind on the change in metamemory knowledge than vice versa. This effect was almost independent of the time period under investigation as well as of earlier language and nonverbal competencies and socioeconomic status. Early language competencies had a direct impact on theory-of-mind and metamemory development and moreover indirectly affected metamemory development through children's theory of mind. The results of the study suggest that children's abilities to metarepresent together with their early language competencies are important in the acquisition of metamemory knowledge. © 2015, Copyright © Taylor & Francis Group, LLC.

Assessing an individual's research impact on the basis of a transparent algorithm is an important task for evaluation and comparison purposes. Besides simple but also inaccurate indices such as counting the mere number of publications or the accumulation of overall citations, and highly complex but also overwhelming full-range publication lists in their raw format, Hirsch (2005) introduced a single figure cleverly combining different approaches. The so-called h-index has undoubtedly become the standard in scientometrics of individuals' research impact (note: in the present paper I will always use the term "research impact" to describe the research performance as the logic of the paper is based on the h-index, which quantifies the specific "impact" of, e.g., researchers, but also because the genuine meaning of impact refers to quality as well). As the h-index reflects the number h of papers a researcher has published with at least h citations, the index is inherently positively biased towards senior level researchers. This might sometimes be problematic when predictive tools are needed for assessing young scientists' potential, especially when recruiting early career positions or equipping young scientists' labs. To be compatible with the standard h-index, the proposed index integrates the scientist's research age (Carbon_h-factor) into the h-index, thus reporting the average gain of h-index per year. Comprehensive calculations of the Carbon_h-factor were made for a broad variety of four research-disciplines (economics, neuroscience, physics and psychology) and for researchers performing on three high levels of research impact (substantial, outstanding and epochal) with ten researchers per category. For all research areas and output levels we obtained linear developments of the h-index demonstrating the validity of predicting one's later impact in terms of research impact already at an early stage of their career with the Carbon_h-factor being approx. 0.4, 0.8, and 1.5 for substantial, outstanding and epochal researchers, respectively. © 2011 Claus-Christian Carbon.
