Media use and Coping in Tweens during the COVID-19 Pandemic.

Public and scholarly debate about the effects of media on youth has been a topic of concern since the twentieth century. These concerns were further amplified and accelerated with heavy use of and reliance on media for everyday living and learning with the homebound conditions brought on by the COVID-19 pandemic. With the public discourse about children's media use and school safety concerns, we conducted online interviews of 36 young people ages 9-14 years to learn about (1) their life situations, including school experience, (2) their overall media use, (3) their overall worries and difficulty with their situations, and (4) their stress management and coping strategies during the fall semester of 2020.

Acoustic dose-behavioral response relationship in sea bass (Dicentrarchus labrax) exposed to playbacks of pile driving sounds.

The foundations of offshore wind turbines are attached to the sea bed by percussion pile driving. Pile driving sounds may affect the behavior of fish. Acoustic dose-behavioral response relationships were determined for sea bass in a pool exposed for 20 min to pile driving sounds at seven mean received root-mean-square sound pressure levels [SPLrms; range: 130-166 dB re 1 μPa; single strike sound exposure level (SEL) range: 122-158; 6 dB steps].

Behavior and body mass changes of a mother and calf Pacific walrus (Odobenus rosmarus divergens) during the suckling period.

The behavior of a 13-year-old female Pacific walrus and her first calf is described during the first 7 months of the 19-month suckling period. The calf vocalized before 62% of suckling sessions. The mother immediately responded after 84% of vocalizations; after 44% she allowed a suckling session.

Hearing thresholds of two harbor seals (Phoca vitulina) for playbacks of multiple pile driving strike sounds.

Pile driving, which creates high amplitude sounds with potentially negative impacts on the marine environment, is used to attach wind turbines to the sea bed. To quantify the distance at which pile driving sounds can be detected by harbor seals, unmasked hearing thresholds were obtained for series of five pile driving sounds recorded at 100 and 800 m from a pile driving location. The played back spectra resembled the spectra of sounds recorded under certain conditions 10-50 km from an offshore pile driving site.

Defining a caring hospital by using currently implemented survey tools.

Health care organizations are constantly striving to provide a more cost-effective and higher quality treatment within a caring environment. However, balancing the demands of regulatory agencies with the holistic needs of the patient is challenging. Further challenging is how to define those hospitals that provide an exceptional caring environment for their patients.

Is the large size of the pinna of the ear of the European hare (Lepus europaeus) due to its role in thermoregulation or in anterior capital shock absorption?

Large pinnae are characteristic of the Leporids, and the pinna is known to have a thermoregulatory role. Another role has been hypothesized for the pinna of Lepus spp., as a part of a suspensory system for the greater portion of the head, absorbing shock that might otherwise interfere with vision during high-speed locomotion.

Relationships between sensitivity to agricultural intensification and ecological traits of insectivorous mammals and arthropods.

We tested the hypothesis that variation in the sensitivity of animals to habitat change is explained by ecological traits (life-history traits, trophic level, and mobility). We measured the sensitivity of insectivorous mammals (shrews and bats) and their prey (arthropods active at the soil surface and nocturnal aerial arthropods) to three aspects of agricultural intensification in a matched-pair experimental design: increased use of agrochemicals (comparison of organic and conventional cereal crops, with pairing for the size of the boundary hedge), change in grassland management from hay to silage (with pairing for the size of the boundary hedge), and increased field size due to hedgerow loss (with boundary-field comparisons as a proxy). We assessed the sensitivity of taxa as the difference in their relative abundance between pairs of high- and low-intensity sites for each aspect of agricultural intensification.

Number and duration of echolocation click trains produced by a harbor porpoise (Phocoena phocoena) in relation to target and performance.

Echolocation effort (number and duration of echolocation click trains produced) by a harbor porpoise is described in relation to target presence, strength and distance, and performance of the detection task. The porpoise was presented with two target sizes at five distances (12-20 m), or no target, and had to indicate whether it could detect the target. Small, distant targets required long and multiple click trains.

The influence of 70 and 120 kHz tonal signals on the behavior of harbor porpoises (Phocoena phocoena) in a floating pen.

Two harbor porpoises in a floating pen were subjected to five pure tone underwater signals of 70 or 120 kHz with different signal durations, amplitudes and duty cycles (% of time sound is produced). Some signals were continuous, others were intermittent (duty cycles varied between 8% and 100%). The effect of each signal was judged by comparing the animals' surfacing locations and number of surfacings (i.

Behavioral avoidance threshold level of a harbor porpoise (Phocoena phocoena) for a continuous 50 kHz pure tone.

The use of ultrasonic sounds in alarms for gillnets may be advantageous, but the deterring effects of ultrasound on porpoises are not well understood. Therefore a harbor porpoise in a large floating pen was subjected to a continuous 50 kHz pure tone with a source level of 122+/-3 dB (re 1 microPa, rms). When the test signal was switched on during test periods, the animal moved away from the sound source.

Startle response of captive North Sea fish species to underwater tones between 0.1 and 64 kHz.

World-wide, underwater background noise levels are increasing due to anthropogenic activities. Little is known about the effects of anthropogenic noise on marine fish, and information is needed to predict any negative effects. Behavioural startle response thresholds were determined for eight marine fish species, held in a large tank, to tones of 0.

Feeding enrichment methods for Pacific walrus calves.

In the wild, walrus calves are occupied with many behaviors necessary for survival. In captivity there is usually less to occupy them. Therefore it is necessary to develop other ways to occupy the animals to prevent negative behavior.

Effects of acoustic alarms, designed to reduce small cetacean bycatch in gillnet fisheries, on the behaviour of North Sea fish species in a large tank.

World-wide many cetaceans drown incidentally in fishing nets. To reduce the unwanted bycatch in gillnets, pingers (acoustic alarms) have been developed that are attached to the nets. In the European Union, pingers will be made compulsory in some areas in 2005 and in others in 2007.

The influence of underwater data transmission sounds on the displacement behaviour of captive harbour seals (Phoca vitulina).

To prevent grounding of ships and collisions between ships in shallow coastal waters, an underwater data collection and communication network (ACME) using underwater sounds to encode and transmit data is currently under development. Marine mammals might be affected by ACME sounds since they may use sound of a similar frequency (around 12 kHz) for communication, orientation, and prey location. If marine mammals tend to avoid the vicinity of the acoustic transmitters, they may be kept away from ecologically important areas by ACME sounds.

Images of mental illness in the media: identifying gaps in the research.

This article summarizes research published over the past decade and identifies areas where future research is needed to increase our knowledge of the media's role in fostering or reducing mental illness stigma. The following questions are addressed: (1) How is mental illness portrayed by the media? (2) How do media images of mental illness impact individuals' knowledge, beliefs, attitudes, and behaviors with regard to mental illness? (3) How can the media be used to reduce mental illness stigma? The review reveals a lack of recent research on the U.S.
