Using PIT-tags and portable antennas for quantification of fish movement and survival in streams under different environmental conditions.

J Fish Biol 2021 Apr 5. Epub 2021 Apr 5.

Department of Fish Ecology and Evolution, EAWAG Swiss Federal Institute of Aquatic Science and Technology, Centre of Ecology, Evolution and Biogeochemistry, Kastanienbaum, Switzerland.

While PIT-tag tracking using mobile antennas is being increasingly used to study fish movement and survival in streams, little is known about the limitations of the method, especially over longer periods of time and under different environmental settings. We used six years of data combining tagging, mobile antenna tracking and recaptures of Salmo trutta in multiple small streams in the Lake Lucerne drainage in Switzerland to evaluate the relative importance of different environmental and intrinsic factors affecting the efficiency of the method. Our study system and experimental design allowed us to accurately verify continuous presence and survival of recaptured fish in the stream after tracking, which meant that we could estimate detection probability with high confidence.

Researching COVID-19 tracing app acceptance: incorporating theory from the technological acceptance model.

PeerJ Comput Sci 2021 4;7:e316. Epub 2021 Jan 4.

Department Financial Economy and Operations Research, University of Sevilla, Sevilla, Spain.

Background: The expansion of the coronavirus pandemic and the extraordinary confinement measures imposed by governments have caused an unprecedented intense and rapid contraction of the global economy. In order to revive the economy, people must be able to move safely, which means that governments must be able to quickly detect positive cases and track their potential contacts. Different alternatives have been suggested for carrying out this tracking process, one of which uses a mobile APP which has already been shown to be an effective method in some countries. Read More

Curr Obstet Gynecol Rep 2021 Mar 31:1-5. Epub 2021 Mar 31.

Obstetrics and Gynecology, Al-Amal Maternity Hospital, Amman, Jordan.

Purpose Of Review: The purpose of this review is to investigate the use and efficacy of fertility tracking applications as a natural contraceptive method since there has been a worldwide increase in the development and use of applications that monitor the menstrual cycle and fertility window. An anonymous online survey had been conducted in order to achieve this goal, and a total of 375 married women from Jordan responded to our survey.

Recent Findings: Topics discussed include fertility awareness-based methods (FAM) of contraception in which mobile applications fall into, and their efficacy and failure rates, comparing them with other methods of contraception while taking into account the typical and perfect use of each method.

Gaze Coordination of Groups in Dynamic Events - A Tool to Facilitate Analyses of Simultaneous Gazes Within a Team.

Front Psychol 2021 17;12:656388. Epub 2021 Mar 17.

Institute of Exercise Training and Sport Informatics, German Sport University Cologne, Cologne, Germany.

The performance and the success of a group working as a team on a common goal depends on the individuals' skills and the collective coordination of their abilities. On a perceptual level, individual gaze behavior is reasonably well investigated. However, the coordination of visual skills in a team has been investigated only in laboratory studies and the practical examination and knowledge transfer to field studies or the applicability in real-life situations have so far been neglected.

ADOS-Eye-Tracking: The Archimedean Point of View and Its Absence in Autism Spectrum Conditions.

Front Psychol 2021 18;12:584537. Epub 2021 Mar 18.

Department of Child and Adolescent Psychiatry, Psychotherapy, and Psychosomatics, Medical Center - University of Freiburg, Faculty of Medicine, University of Freiburg, Freiburg, Germany.

Face perception and emotion categorization are widely investigated under laboratory conditions that are devoid of real social interaction. Using mobile eye-tracking glasses in a standardized diagnostic setting while applying the Autism Diagnostic Observation Schedule (ADOS-2), we had the opportunity to record gaze behavior of children and adolescents with and without Autism Spectrum Conditions (ASCs) during social interaction. The objective was to investigate differences in eye-gaze behavior between three groups of children and adolescents either (1) with ASC or (2) with unconfirmed diagnosis of ASC or (3) with neurotypical development (NTD) during social interaction with an adult interviewer in a diagnostic standard situation using the ADOS-2.

Positional head-eye tracking outside the lab: an open-source solution.

Proc Eye Track Res Appl Symp 2020 Jun;2020

University of Nevada, Reno, Reno, Nevada.

Simultaneous head and eye tracking has traditionally been confined to a laboratory setting and real-world motion tracking limited to measuring linear acceleration and angular velocity. Recently available mobile devices such as the Pupil Core eye tracker and the Intel RealSense T265 motion tracker promise to deliver accurate measurements outside the lab. Here, the researchers propose a hard- and software framework that combines both devices into a robust, usable, low-cost head and eye tracking system. Read More
