Background Coping plays an important role for emotion regulation in threatening situations. The model of coping modes designates repression and sensitization as two independent coping styles. Repression consists of strategies that shield the individual from arousal. Sensitization indicates increased analysis of the environment in order to reduce uncertainty. According to the discontinuity hypothesis, repressors are sensitive to threat in the early stages of information processing. While repressors do not exhibit memory disturbances early on, they manifest weak memory for these stimuli later. This study investigates the discontinuity hypothesis using functional magnetic resonance imaging (fM…

Despite the positive aspects of information technology (IT) use, it is common for users to experience negative IT incidents. Examples of negative IT incidents include getting lost in an unfamiliar country due to a dysfunctional map application and missing a monetary insurance benefit due to the failure of an activity tracker application. Such incidents can harm IT providers by giving rise to user dissatisfaction, discontinued use, switching, and negative word-of-mouth. To minimize this harm, it is important to understand how users cope after negative incidents. Specifically, information systems (IS) researchers have called for research that uncovers the complex interplay of IT users’ coping…
Vínculos familiares e inclusión social. Variables predictoras de la conducta prosocial en la infancia
2018
The purpose of this study was to investigate the relationship between prosocial behavior and family environment variables (attachment to the mother and father and abandonment by the mother and father), personal variables (emotional instability, aggression, and coping strategies), and variables that relate to the immediate social environment (peer acceptance and rejection). This study also examined the predictors of prosocial behavior. Prosocial behavior is a personal protective factor that encourages positive relationships between peers and promotes personal and social adjustment behaviors (Mikolajewski, Chavarria, Moltisanti, Hart & Taylor, 2014). A study with a sample of 1,447 chi…
Maternal stress and coping strategies in developmental Dyslexia: An Italian multicenter study
2017
BackgroundStudies about the impact of developmental dyslexia (DD) on parenting are scarce. Our investigation aimed to assess maternal stress levels and mothers’ copying styles in a population of dyslexic children.MethodsA total of 874 children (500 boys, 374 girls; mean age 8.32 ± 2.33 years) affected by DD was included in the study. A total of 1,421 typically developing children (789 boys, 632 girls; mean age 8.25 ± 3.19 years) were recruited from local schools of participating Italian Regions (Abruzzo, Calabria, Campania, Puglia, Umbria, Sicily) and used as control-children group. All mothers (of both DD and typically developing children) filled out an evaluation for parental stress (Pare…
Coping with School-Related Stress and Family Stress in Healthy and Clinically Referred Adolescents
2001
This study compares stress perception and coping style in 77 early and late adolescents differing in psychological health. Coping with two normative, age-specific stressors, namely, school-related stressors, and conflicts with parents was investigated via the Coping Process Interview, which assesses coping immediately after an event has happened. Results obtained from the interviews were validated by the results of standardized questionnaires assessing stress perception and coping style in dealing with school-related stress and family stress. Both stressors were not perceived as structurally similar events. Differences were obtained with respect to the appraisal of the stressor, causal att…
Depression bei Kindern und Jugendlichen: Prävalenz, Diagnostik, ätiologische Faktoren, Geschlechtsunterschiede, therapeutische Ansätze
2007
Die Prävalenzraten für die verschiednen Formen von Depression (depressiven Stimmungen, depressiven Syndromen und Major Depression) haben in den letzten Jahren zugenommen, die Geschlechtsunterschiede mit deutlich höheren Raten für Mädchen haben sich erhöht. Als ätiologische Faktoren für das Auftreten von Depression werden u. a. zunehmende Stressfaktoren, dysfunktionale Bewältigungsstile, ein negatives Körperkonzept und unsichere Bindungsmuster genannt. Unter den verschiedenen therapeutischen Ansätzen hat sich die psychoananlytische Behandlungsmethode als die umfassendste erwiesen. Schlüsselwörter Prävalenzraten - Komorbidität - Stress - Coping - Körperkonzept - Bindung Prevalence rates of th…
Density functional theory description of random Cu-Au alloys
2019
Density functional alloy theory is used to accurately describe the three core effects controlling the thermodynamics of random Cu-Au alloys. These three core effects are exchange correlation (XC), local lattice relaxations (LLRs), and short-range order (SRO). Within the real-space grid-based projector augmented-wave (GPAW) method based on density functional theory (DFT), we adopt the quasinonuniform XC approximation (QNA), and take into account the LLR and the SRO effects. Our approach allows us to study the importance of all three core effects in a unified way within one DFT code. The results demonstrate the importance of the LLR term and show that going from the classical gradient level a…
A Mobile Healthcare System for Sub-saharan Africa
2013
The disparity between healthcare systems in developed countries and underdeveloped countries is huge, particularly due to the fact that the healthcare infrastructure of former is based on a sophisticated technological infrastructure. Efforts are being made worldwide to bridge this disparity and make healthcare services affordable even to the most remote areas of undeveloped countries. Recent growth of mobile networks in underdeveloped countries argues for building mHealth systems and applications on their basis. However, peculiarities of the area introduce difficulties into potential use cases of mobile devices, thus making the copying of mHealth services from developed countries inapplicab…
Myocardial Perfusion and Fractional Flow Reserve
2013
Myocardial CT perfusion imaging is a rapidly evolving technology that allows assessment of the functional significance of potentially obstructive coronary stenosis. The opportunity for quantification of myocardial perfusion is the greatest potential advantage of CT compared with other perfusion techniques. On the other hand, fractional flow reserve during coronary angiography provides a functional assessment of coronary lesions identified with this modality. Recently, a non-invasive method for estimating fractional flow reserve, based on coronary CT angiography has been introduced. Nevertheless, at present neither CT perfusion nor CT FFR are ready for widespread use in clinical routine.
Noise influence on correlated activities in a modular neuronal network: From synapses to functional connectivity
2008
In this work we propose taking noise into account when modeling the neuronal activity in a correlation-based type network. Volume transmission effects on connectivity are considered. As a result, an individual module can be set in an "activated" state via noise produced by the remaining modules. The stochastic approach could provide a new insight into the relation between functional and anatomical connectivity.
