A Computational Cognitive Model Integrating Different Emotion Regulation Strategies

AbstractIn this paper a cognitive model is introduced which integrates a model for emotion generation with models for three different emotion regulation strategies. Given a stressful situation, humans often apply multiple emotion regulation strategies. The presented computational model has been designed based on principles from recent neurological theories based on brain imaging, and psychological and emotion regulation theories. More specifically, the model involves emotion generation and integrates models for the emotion regulation strategies reappraisal, expressive suppression, and situation modification. The model was designed as a dynamical system. Simulation experiments are reported showing the role of the emotion regulation strategies. The simulation results show how a potential stressful situation in principle could lead to emotional strain and how this can be avoided by applying the emotion regulation strategies decreasing the stressful effects

Groundwater Quality Assessment for Drinking Purpose of Taluka Chachro, Thar Desert, Pakistan; Using Water Quality Indices, and Geospatial Techniques

Groundwater quality of taluka Chachro was investigated by analyzing thirty-two groundwater samples for drinking purpose. Multivariate statistical approaches with GIS interpolations (IDW) were applied for the identification of significant geochemical processes governing the groundwater quality.. Results showed the concentrations of physiochemical parameter in the study area exceeded the prescribed level of WHO guidelines. The EC and TDS varied from 2593-18950 µS/cm and 1659-12128 mg/l, respectively. The Ca, Mg, Na, and K range from 36-288, 17-272, 420-3280, and 9.5-101 mg/l, respectively. While, Cl, HCO3, SO4, and NO3 varied from 539-5738, 210-1150, 79-870, and 6.66-17.13 mg/l respectively. The mean values of EC, TDS, Na, Cl, HCO3, SO4, and NO3 were higher than the prescribed level of WHO 2011. Higher concentrations above the acceptable limits were recorded for K 96.15%, SO488.46%, and HCO3 82.16% of analysed samples. Multivariate statistical analysis suggested that the input of natural processes have influenced groundwater quality which resulted in changing the groundwater chemistry of taluka Chachro. The results revealed the dominant trend among the cations was Na>Ca>Mg>K while among the anions it was Cl>HCO3>SO4. Based on the drinking water quality index 50% were unsuitable for drinking

Assessment of Climate Driven Changes in Flow Series of Alpine Basin: A Case Study of Danube River Basin

This study was carried out in order to analyze the climate change driven influence on mean monthly flow series of Danube River and its tributaries during the last century. The study confirms some signs of climate driven alterations in monthly river flow series along with change in flow seasonality during the last century. In spite of this, man-made interference in the basin like i.e. groundwater extraction, irrigation, river regulation, land use alteration and urbanization, has significantly changed Danube flow regime in most areas of the catchment. The analysis of Achleiten station demonstrates that average annual flow regime is a little bit increased. Major increase is observed in winter and autumn months and decrease in summer months. These seasonal alterations clearly signal a future glimpse of reduced water availability in alpine basins. This will mainly occur due to the change in the form of precipitation in winter, from snow to rain and the consequent less snow accumulation, and the early melt of snow storage, less precipitation and high evaporation rate in summer

AbstractThis paper addresses the role of emotion regulation in a social context by means of a computational social agent model. The model integrates three different phenomena namely emotion regulation, emotion contagion, and emotion-related valuing, in order to analyse the role of emotion regulation in socially affected decision making. The work presented in this paper is illustrated for the interaction between two persons, simulated through agent-based modelling methods. Simulation experiments for different kinds of parameter settings help to understand the underlying mechanism of socially affected decision making and how these decisions can be affected by regulating the emotions involved. Based on the introduced model an ambient intelligent system can be designed to monitor and support a person, for example, to adopt a healthy lifestyle

Encouraging physical activity via a personalized mobile system

Engaging in sufficient physical activity has several beneficial effects on physical and mental health. Still, a large proportion of the Western population doesn't meet the guidelines of being moderately to vigorously active for a minimum of 30 minutes on at least five days a week. Mobile technology provides possibilities for personalized coaching systems, and the results of existing mobile interventions look promising. Here, the authors present a mobile system that goes beyond existing (mobile) physical activity interventions. The approach combines theory and evidence-based behavior-change techniques with a model-based reasoning system, to provide the right support and strategies at the right time for obtaining a physically active lifestyle
