This cross-sectional study assessed associations between social-emotional development in young children and their number of daily routines involving an electronic screen. We hypothesized with poor have a significant portion occurring Two hundred ten female caregivers typically developing 12 to 36 months old completed the Ages Stages Questionnaire: Social-Emotional (ASQ: SE) media diary. Caregivers diary for 1 day around 10 (Waking Up, Diapering/Toileting, Dressing, Breakfast, Lunch, Naptime,...
Abstract An acoustic survey of Cuvier's beaked whales ( Ziphius cavirostris ) was conducted off the U.S. West Coast in August and September 2016 using drifting recorder systems with a vertical array two hydrophones at depth ~110 m. Recorders were deployed 22 times to representatively cover 1,058,000 km 2 study area from shelf break ~556 offshore. Vertical angles echolocation pulses measured signal time‐difference‐of‐arrival on hydrophones. Echolocation identified their arrival (always below...
Abstract Belugas ( Delphinapterus leucas ) and narwhals Monodon monoceros are highly social Arctic toothed whales with large vocal repertoires similar acoustic profiles. Passive Acoustic Monitoring (PAM) that uses multiple hydrophones over spatiotemporal scales has been a primary method to study their populations, particularly in response rapid climate change increasing underwater noise. This marks the first comparison between wild belugas from same location reveals they can be acoustically...
Abstract Beaked whales produce frequency‐modulated echolocation pulses that appear to be species‐specific, allowing passive acoustic monitoring play a role in understanding spatio‐temporal patterns. The Cross Seamount beaked whale is known only from its unique signal (BWC) with no confirmed species identification. This spans the Pacific Ocean Mariana Archipelago Baja California, Mexico, south equator, but as far north latitude 29°N. Within these warm waters, 92% of BWC detections occurred at...
Passive acoustic monitoring is increasingly used for assessing populations of marine mammals; however, analysis large datasets limited by our ability to easily classify sounds detected. Classification beaked whale events, in particular, requires evaluation multiple lines evidence expert analysts. Here we present a highly automated approach detection and classification using supervised machine learning open source software methods. Data from four scale surveys whales (northwestern North...
The distribution, abundance, and habitat of cryptic cetacean species such as beaked whales dwarf/pygmy sperm ( Kogia spp.) are challenging to study due their long dive times and/or very limited surface behavior. Even less is known in minimally studied remote regions, including the Mariana Archipelago parts broader western Pacific. In 2018, we deployed a network eight Drifting Acoustic Spar Buoy Recorders (DASBRs) on west side with goal examining distribution spp. this region using passive...
In spring/summer of 2018 and 2021, the Pacific Islands Fisheries Science Center Cetacean Research Program deployed drifting acoustic recorders in U.S. Exclusive Economic Zones surrounding Mariana Archipelago. Manual assessments revealed a low-frequency (median 473–554 Hz), short-duration 0.596 s), stereotypic tonal nocturnal call throughout Based on time year, spatiotemporal patterns, clear division among calls (i.e., no chorusing), comparisons with known vocalizations whales, turtles, fish,...
Use of underwater passive acoustic datasets for species-specific inference requires robust classification systems to identify encounters species from characteristics detected sounds. A suite routines designed efficiently detect cetacean sounds, extract features, and classify the detection is described using ship-based, visually verified detections false killer whales (Pseudorca crassidens). The best-performing model included features clicks, whistles, burst pulses, which correctly classified...
Two studies examined forgiveness recipients' evaluations of, and responses to, four styles of forgiveness-granting communication: engaging, deemphasizing, conditional, suppressing. In the context close friendships, Study 1 showed that whereas engaging style was highly preferred, suppressing conditional were not. Content analysis suggested latter two are perceived as unclear, inauthentic, and/or in violation norms. 2 is preferable because it effectively addresses personal relational face...
Given the economic climate United States is facing, understanding how consumers are socialized could help lead to solutions that alleviate average citizen's financial outlook. This study sought explain influence of coviewing on materialism among college students. Eighty-one undergraduates were surveyed about their exposure television, frequency with peers, and materialistic attitudes. For those students who coview more often, there a positive relationship between television attitudes, r (48)...
In 2014, a novel call was discovered in autonomous acoustic recordings from the Mariana Archipelago and designated “Biotwang”. It assumed to be produced by baleen whale, but without visual verification it impossible assign species. Using combination of survey data collected Archipelago, we determined that Biotwangs are Bryde’s whales. whales occur worldwide tropical warm temperate waters, their population structure movements not well understood. Genetic morphological recognize two...
Understanding the vocal behavior of cetaceans is an important component many passive acoustic applications. This study quantifies subgroups false killer whales ( Pseudorca crassidens ) from Hawaiian Archipelago. The (N = 523) exhibit diverse that varies between encounters. Overall, 29% only echolocate, 16% whistle, and 55% emit both types vocalizations. These results contribute information for developing automated cetacean tracking, localization, classification techniques, thus, support...

Passive acoustic monitoring is an effective technique for studying cetacean presence within marine protected areas (MPAs). The Hawaiian archipelago home to 18 species of resident toothed whales, but little known regarding the spatio-temporal variability false killer whales (Pseudorca crassidens—FKW) and short-finned pilot (Globicephala macrorhynchus) across Hawai‘i MPAs. Bottom-moored recorders were deployed inside outside Islands Humpback Whale National Marine Sanctuary Papahānaumokuākea...
The Hawaiian Archipelago is home to three distinct populations of false killer whales (Pseudorca crassidens), including one currently listed as endangered. These delphinids are known interact with fishing gear, leading whale mortality or injury. Hence, it critical assess the abundance these typically achieved through visual-based sighting surveys. However, surveys complicated by a number biases and uncertainties specific this species. Passive acoustics could aid in monitoring their...
False killer whales (Pseudorca crassidens) and short-finned pilot (Globicephala macrorhynchus) are resident, toothed whale species to the Hawaiian archipelago. considered of high concern in Hawai‘i with insular population listed as endangered. Passive acoustic monitoring (PAM) is an effective technique for studying these highly social odontocete on large temporal geographical scales. Moored hydrophones were deployed inside outside Marine Protected Areas (MPAs) through SanctSound project,...
