Towards estimating computer users' mood from interaction behaviour with keyboard and mouse

The purpose of this exploratory research was to study the relationship between the mood of computer users and their use of keyboard and mouse to examine the possibility of creating a generic or individualized mood measure. To examine this, a field study (n = 26) and a controlled study (n = 16) were conducted. In the field study, interaction data and self-reported mood measurements were collected during normal PC use over several days. In the controlled study, participants worked on a programming task while listening to high or low arousing background music. Besides subjective mood measurement, galvanic skin response (GSR) data was also collected. Results found no generic relationship between the interaction data and the mood data. However, the results of the studies found significant average correlations between mood measurement and personalized regression models based on keyboard and mouse interaction data. Together the results suggest that individualized mood prediction is possible from interaction behaviour with keyboard and mouse

Hurricane Impacts on the Foraging Patterns of Bottlenose Dolphins \u3ci\u3eTursiops truncatus\u3c/i\u3e in Mississippi Sound

Acute catastrophic events, such as hurricanes, have various degrees of impact on marine mammal populations. Although changes in environmental conditions of affected areas have been examined for many storms, little attention has been given to the ecological effects on top-level predators. A longitudinal study on bottlenose dolphin Tursiops truncatus behavior and distribution in Mississippi Sound has been ongoing since 2003, allowing the unique opportunity to examine the impacts of the passage of Hurricane Katrina on this coastal dolphin population. Previous research showed an increase in reproductive rates within this population following Hurricane Katrina, most likely due to an increase in prey density following the sharp decline in commercial fishing efforts. In this paper, the frequency and distribution of dolphin foraging encounters in Mississippi Sound were examined from 2003 to 2009, revealing both short-and potentially long-term effects on dolphin foraging patterns following the hurricane. A pulse in dolphin foraging encounters was observed, which increased by similar to 15% in the 2 yr following the hurricane before returning to pre-Katrina levels. Statistically significant hot spots were identified through the use of the Getis-Ord Gi* hot spot analysis and revealed spatial shifts in foraging habitat consistent with prey selectivity. The results of this study support previous findings that coastal bottlenose dolphins in the southeastern United States are selective feeders, preferring to forage in deeper water known for soniferous prey species. Furthermore, this study presents important baseline information for future studies investigating other acute catastrophic events in Mississippi Sound, such as cumulative impacts following the Deepwater Horizon oil spill

Gauging the influence of increased search effort on reporting rates of bottlenose dolphin (<i>Tursiops truncatus</i>) strandings following the deepwater horizon oil spill

<div><p>The co-occurrence of the Deepwater Horizon oil spill and the northern Gulf of Mexico cetacean Unusual Mortality Event have raised questions about the stability of inshore bottlenose dolphin (<i>Tursiops truncatus</i>) populations throughout the region. Several factors could have contributed to the ongoing event, but little attention has been paid to the potential effects of increased search effort and reporting of strandings associated with oil spill response activities, which were widespread for an extended period. This study quantified the influence of increased search effort by estimating the number of bottlenose dolphin strandings reported by oil spill responders and comparing monthly stranding rates with and without response-related records. Results showed that response teams reported an estimated 58% of strandings during the Active Response period within the study area. Comparison of Poisson rates tests showed that when responder-influenced stranding records were removed, the monthly stranding rates from the Active Response period (May 2010 –April 2014) were similar to the Post-Removal Actions Deemed Complete period (May 2013 –March 2015) (e.g., <i>p</i> = 0.83 for remote areas in Louisiana). Further, analyses using the Getis-Ord Gi* spatial statistic showed that when response-related stranding reports were removed from the Active Response period, significant spatial clustering of strandings (<i>p</i> < 0.05) was reduced by 48% in coastal Louisiana. Collectively, these results suggest that increased search effort resulting from the Deepwater Horizon oil spill response throughout remote portions of the Unusual Mortality Event geographic region had the capacity to increase reporting and recovery of marine mammal strandings to unusually high levels. To better understand how stranding data relates to actual mortality, more work is needed to quantify dolphin population size, population trends, and carcass detection rates including the role of search effort. This is vital for understanding the status of a protected species within the northern Gulf of Mexico.</p></div
