The psychophysics of affordance perception: Stevens' power law scaling of perceived maximum forward reachability with an object.

The literatures on affordance perception and psychophysics are seminal in the basic study of perception and action. Nevertheless, the application of classic psychophysical methodologies/analysis to the study of affordance perception remains unexplored. In four experiments, we investigated the Stevens' power law scaling of affordance perception.

Can This Provider Be Trusted? A Review of the Role of Trustworthiness in the Provision of Community-Based Services for Intimate Partner Violence Survivors.

While there is a growing literature on intimate partner violence (IPV) survivors and service providers, it is limited by its largely atheoretical and descriptive nature, and its emphasis on individual-level survivors' help-seeking. We seek to broaden our understanding by shifting the focus onto organizations and service systems and introducing the concept of these providers' trustworthiness toward survivors. Provider trustworthiness in delivering services includes benevolence (locally available and caring), fairness (accessible to all and non-discriminatory), and competence (acceptable and effective in meeting survivors' needs).

A Machine Learning Framework for Assessing the Risk of Venous Thromboembolism in Patients Undergoing Hip or Knee Replacement.

Venous thromboembolism (VTE) is a well-recognized complication that is prevalent in patients undergoing major orthopedic surgery (e.g., total hip arthroplasty and total knee arthroplasty).

Effects of sensorimotor voice training on event-related potentials to pitch-shifted auditory feedback.

The pitch perturbation technique is a validated technique that has been used for over 30 years to understand how people control their voice. This technique involves altering a person's voice pitch in real-time while they produce a vowel (commonly, a prolonged /a/ sound). Although post-task changes in the voice have been observed in several studies (e.

Varieties of corona news: a cross-national study on the foundations of online misinformation production during the COVID-19 pandemic.

Unlabelled: Misinformation in the media is produced by hard-to-gauge thought mechanisms employed by individuals or collectivities. In this paper, we shed light on what the country-specific factors of falsehood production in the context of COVID-19 Pandemic might be. Collecting our evidence from the largest misinformation dataset used in the COVID-19 misinformation literature with close to 11,000 pieces of falsehood, we explore patterns of misinformation production by employing a variety of methodological tools including algorithms for text similarity, clustering, network distances, and other statistical tools.

Personality and responses to Covid-19 health and safety prevention.

In this study, we examine the respective effects of prosocial personality and grandiose narcissism on individual social responsibility, and attitudinal and behavioral responses to Covid-19 health and safety preventive measures. We further analyze the extent to which individuals feel targeted by bullies for wearing a mask in order to shed light on the psychological consequences of the current pandemic. We employed a cross-sectional technique using a snowball sampling method to recruit participants from the United States and Canada.

Beyond a biased binary: A perspective on the misconceptions, challenges, and implications of studying females in avian behavioral endocrinology.

For decades, avian endocrinology has been informed by male perspectives and male-focused research, leaving significant gaps in our understanding of female birds. Male birds have been favored as research subjects because their reproductive behaviors are considered more conspicuous and their reproductive physiology is presumably less complex than female birds. However, female birds should not be ignored, as female reproductive behavior and physiology are essential for the propagation of all avian species.

Direct-reading instruments for aerosols: A review for occupational health and safety professionals part 2: Applications.

Direct reading instruments (DRIs) for aerosols have been used in industrial hygiene practice for many years, but their potential has not been fully realized by many occupational health and safety professionals. Although some DRIs quantify other metrics, this article will primarily focus on DRIs that measure aerosol number, size, or mass. This review addresses three applications of aerosol DRIs that occupational health and safety professionals can use to discern, characterize, and document exposure conditions and resolve aerosol-related problems in the workplace.

Direct-reading instruments for aerosols: A review for occupational health and safety professionals part 1: Instruments and good practices.

With advances in technology, there are an increasing number of direct-reading instruments available to occupational health and safety professionals to evaluate occupational aerosol exposures. Despite the wide array of direct-reading instruments available to professionals, the adoption of direct-reading technology to monitor workplace exposures has been limited, partly due to a lack of knowledge on how the instruments operate, how to select an appropriate instrument, and challenges in data analysis techniques. This paper presents a review of direct-reading aerosol instruments available to occupational health and safety professionals, describes the principles of operation, guides instrument selection based on the workplace and exposure, and discusses data analysis techniques to overcome these barriers to adoption.

SNAPSHOT USA 2020: A second coordinated national camera trap survey of the United States during the COVID-19 pandemic.

Managing wildlife populations in the face of global change requires regular data on the abundance and distribution of wild animals, but acquiring these over appropriate spatial scales in a sustainable way has proven challenging. Here we present the data from Snapshot USA 2020, a second annual national mammal survey of the USA. This project involved 152 scientists setting camera traps in a standardized protocol at 1485 locations across 103 arrays in 43 states for a total of 52,710 trap-nights of survey effort.

Potency matters: Impacts of embryonic exposure to nAChR agonists thiamethoxam and nicotine on hatching success, growth, and neurobehavior in larval zebrafish.

Thiamethoxam (TM) is a neonicotinoid insecticide that acts as a nicotinic acetylcholine receptor (nAChR) agonist. While designed to specifically target invertebrate nAChRs, recent studies have reported adverse effects of neonicotinoid exposure in early life-stage fish. This study examined the health and neurobehavioral impacts of chronic exposure to various concentrations of TM or nicotine (NIC) in early life zebrafish () in conjunction with molecular docking to compare their ligand-receptor interactions with vertebrate nAChR.

Differentiable Optimization of Generalized Nondecomposable Functions using Linear Programs.

We propose a framework which makes it feasible to directly train deep neural networks with respect to popular families of task-specific non-decomposable performance measures such as AUC, multi-class AUC, -measure and others. A feature of the optimization model that emerges from these tasks is that it involves solving a Linear Programs (LP) during training where representations learned by upstream layers characterize the constraints or the feasible set. The constraint matrix is not only large but the constraints are also modified at each iteration.

Physiological acclimatization in Hawaiian corals following a 22-month shift in baseline seawater temperature and pH.

Climate change poses a major threat to coral reefs. We conducted an outdoor 22-month experiment to investigate if coral could not just survive, but also physiologically cope, with chronic ocean warming and acidification conditions expected later this century under the Paris Climate Agreement. We recorded survivorship and measured eleven phenotypic traits to evaluate the holobiont responses of Hawaiian coral: color, Symbiodiniaceae density, calcification, photosynthesis, respiration, total organic carbon flux, carbon budget, biomass, lipids, protein, and maximum Artemia capture rate.

Selective Boosting of CCR7-Acting Chemokines; Short Peptides Boost Chemokines with Short Basic Tails, Longer Peptides Boost Chemokines with Long Basic Tails.

The chemokine receptor CCR7 and its ligands CCL19 and CCL21 regulate the lymph node homing of dendritic cells and naïve T-cells and the following induction of a motile DC-T cell priming state. Although CCL19 and CCL21 bind CCR7 with similar affinities, CCL21 is a weak agonist compared to CCL19. Using a chimeric chemokine, CCL19, harboring the N-terminus and the C-terminus of CCL21 attached to the core domain of CCL19, we show that these parts of CCL21 act in a synergistic manner to lower ligand potency and determine the way CCL21 engages with CCR7.

Structural Insights into Molecular Recognition by Human Chemokine CCL19.

The human chemokines CCL19 and CCL21 bind to the G protein-coupled receptor (GPCR) CCR7 and play an important role in the trafficking of immune cells as well as cancer metastasis. Conserved binding sites for sulfotyrosine residues on the receptor contribute significantly to the chemokine/GPCR interaction and have been shown to provide promising targets for new drug-discovery efforts to disrupt the chemokine/GPCR interaction and, consequently, tumor metastasis. Here, we report the first X-ray crystal structure of a truncated CCL19 (residues 7-70) at 2.

Embryonic Exposure to Thiamethoxam Reduces Survival and Alters Neurobehavior of Fathead Minnows.

Thiamethoxam is a commonly used neonicotinoid insecticide that acts as a nicotinic acetylcholine receptor (nAChR) agonist. Although vertebrates are less sensitive to neonicotinoid insecticides than invertebrates, some neonicotinoids have been shown to cause neurobehavioral changes in larval fishes. In the present study, we examine the neurobehavioral toxicity of acute and chronic exposure to environmentally relevant concentrations of thiamethoxam in fathead minnows at two different life stages.
