Flexible emotion regulatory selection when coping with COVID-19-related threats during quarantine

The COVID-19 pandemic poses significant emotional challenges that individuals need to select how to regulate. The present study directly examined how during the pandemic, healthy individuals select between regulatory strategies to cope with varying COVID-19-related threats, and whether an adaptive flexible regulatory selection pattern will emerge in this unique threatening global context. Accordingly, this two-study investigation tested how healthy individuals during a strict state issued quarantine, behaviorally select to regulate COVID-19-related threats varying in their intensity. Study 1 created and validated an ecologically relevant set of low and high intensity sentences covering major COVID-19 facets that include experiencing physical symptoms, infection threats, and social and economic consequences. Study 2 examined the influence of the intensity of these COVID-19-related threats, on behavioral regulatory selection choices between disengagement via attentional distraction and engagement via reappraisal. Confirming a flexible regulatory selection conception, healthy individuals showed strong choice preference for engagement reappraisal when regulating low intensity COVID-19-related threats, but showed strong choice preference for disengagement distraction when regulating high intensity COVID-19-related threats. These findings support the importance of regulatory selection flexibility for psychological resilience during a major global crisis.

Web-based macroseismic intensity study in Turkey – entries on Ekşi Sözlük

Ekşi Sözlük is one of the most visited websites in Turkey. Registered users of the website share their knowledge about any topic. In this study, we collect the user entries on the topic of 20 earthquakes in Turkey and the surrounding area. Entries with city and district level information are converted to intensity values. Shake maps of the earthquakes are created by using a ground motion to intensity conversion equation. User entries and created shake maps are compared. It is found that entries correlate with the predicted intensities. It is also found that local soil conditions and building types have an amplifier effect on entries on the website. Several entries on the earthquake topics have magnitude estimations. The difference between predicted and observed intensities also varies with distance. Users are able to predict the magnitudes of the earthquakes with ±0.54 misfit. This study shows that Ekşi Sözlük has the potential to be a reliable source of macroseismic intensity for the earthquakes in Turkey if the felt reports are collected with a predetermined format.

The Extent of Capacity Loss Caused by Rainfall at Signalised Intersections

Background: Even though their physical characteristics exert a constant influence on capacity and saturation flows, signalized intersections are fixed facilities not affected by rainfall. Whilst traffic conditions with varying effects can be regulated, rainfall conditions cannot be regulated but compensated for by warning drivers to reduce speed. Speed reduction has an impact on signalised intersection capacity, whilst signalised intersection capacity is a function of saturation flow, effective green, and cycle time. In this paper, a capacity loss is the differential percentage between ‘with and without’ rainfall scenario. Aim: The paper investigated the extent of capacity loss caused by rainfall at signalised intersections. Methods: In Durban, South Africa, rainfall data were collected, collated, and correlated with traffic data in a 'with and without' rainfall intensity study. Rainfall intensity was classified according to the rate of precipitation as follows; rainfall intensity(i): light rain (i <2.5mm/h); Moderate rain (2.5mm/h ≤ i < 10mm/h), and heavy rain (10 ≤ i ≤ 50mm/h) as prescribed by the World Meteorological Society. Results: Empirical results show that rainfall intensity has an effect on road capacity at a signalised intersection. Generally, for the vehicles going straight, light rain caused a 4.25% capacity loss; moderate rain 9.18% while heavy rain caused an 11.53% capacity reduction. With right-turning vehicles, light rain caused 7.38% capacity loss; moderate rain caused 14.3%, while heavy rain accounted for 19.15% capacity reduction. Conclusion: The paper concluded that rainfall at signalised intersections would cause an anomalous capacity reduction. Since the database for the study is small, the paper advocates for further studies based on a broader database to include yellow interval time.

The Roots of Rivalry

This chapter provides a foundation for those new to rivalry inquiry. First, it introduces seminal social psychology concepts, such as group identity, social identity theory, social categorization theory, and ingroup/outgroup formation. Next, the chapter explains three properties of rivalry and the 100-point single-item measure of rivalry intensity. Study 1 examines these in new leagues (MLB, MLS, NBA), finding robust support for rivalry as 1) non-exclusive (fans perceive multiple rivals), 2) continuous in scale (intensity varies among rivals), and 3) bidirectional (opposing fans rarely share equivalent perceptions of the rivalry). Study 2 explains 11 rivalry antecedents and investigates their manifestation within five sport leagues (MLB, MLS, NBA, NFL, NHL). These are, in descending order of influence: frequency of play, defining moments, recent parity, star factors, geography, relative dominance, historical parity, competition for personnel, cultural difference, unfairness, and cultural similarity. The authors close by noting limitations and future directions for rivalry research.

The influence of magnetic field and cathode dimensions on plasma characteristics in hollow cathode system

Experimental study on the effect of cylindrical hollow cathode, working pressure and magnetic field on spatial glow distribution and the characteristics of plasma produced by dc discharge in Argon gas, were investigated by image analyses for the plume within the plasma. It was found that the emission intensity appears as a periodic structure with many peaks appeared between the electrodes. Increasing the pressure leads to increase the number of intensity peaks finally converted to continuous form at high pressure, especially with applied of magnetic field, i.e. the plasma is more stable with the presence of magnetic field. The emission intensity study of plasma showed that the intensity has a maximum value at 1.07 mbar pressure and decrease with more pressure.

Cyclonic intensity study using sea level pressure estimations from Ocensat-II scatterometer winds over Bay of Bengal during 2013

Sea level pressure (SLP) fields prevailing over Bay of Bengal (BoB) during Phailin, Lehar and Madi cyclones (2013) were estimated using University of Washington Planetary Boundary Layer (UWPBL) model with Oceansat-II Scatterometer (OSCAT) sea surface winds as an input parameter. Model performance in estimating SLP variations during cyclonic periods was investigated by comparison against cyclone reports of Indian Meteorological Department (IMD) and in-situ measurements. Pressure drop as per IMD reports were observed to be higher than model estimates, primarily due to limitations in scatterometer wind data. However, model retrieved pressure fields compare well against buoy measurements, with a bias of 0.0042, −0.1279 and −0.4406 observed for Phailin, Lehar and Madi cyclones respectively. The contrast in pressure drops between model estimates and IMD reports was investigated by comparing scatterometer winds against IMD reported maximum sustainable winds.

Hurt Feelings in Women: The Interaction of Social and Individual Difference Factors

Research into the causes of hurt feelings has generally examined the impact of single predictors. The current article builds on previous literature by examining the interactive effects of several key elements of hurtful events in predicting the intensity of hurt. Two studies using community samples of women examined interactions between the type of hurtful event, the importance of the perpetrator, and victim hurt-proneness in predicting variance in hurt intensity. Study 1 (n = 475) used a series of scenarios as the hurtful stimulus while Study 2 (n = 380) used a number of recalled hurtful events. Both studies replicated previous bivariate relationships between perpetrator importance and hurt-proneness and the intensity of hurt, while the first study also demonstrated a significant effect for type of hurtful event. Both studies also found a significant three-way interaction between these variables, indicating that victim hurt-proneness only predicted the intensity of hurt at lower levels of event severity and perpetrator importance. It is concluded that the experience of hurt is multidimensional and contextual. Future directions for research involving gender differences and interventions for individuals and couples are discussed.
