The History of the Brazilian Sardine () Between Two Fishery Collapses: An Ecosystem Modeling Approach to Study Its Life Cycle.

The inter-annual fluctuations of abundance of the Brazilian sardine () during the last decades have deeply modified the purse seine fishery dynamics. This study evaluates the trophic relationships of the main species exploited by this fishery and the importance of its biomass for the southeast-south Brazil marine ecosystem (22° S-34° S). Data were analyzed using a mass balance model (ECOPATH) between the two fishery collapses: 2000 and 2017.

Analysis of skew, examination of intercorrelations, and determining the optimal threshold for performance invalidity when 10 performance validity tests are administered during a neuropsychological evaluation.

Introduction: This study cross-validates and expands upon previous research by examining the optimal number of PVT failures necessary to determine invalid performance when 10 PVTs are administered during a neuropsychological evaluation. Additionally, the study assessed the degree of skewness of individual PVTs and PVT intercorrelations for the overall sample and by validity group.

Method: Participants were 283 adult neuropsychology outpatients evaluated at an academic medical center.

Changes in Support for Advance Provision and Over-the-Counter Access to Medication Abortion.

Importance: Since Dobbs v Jackson Women's Health Organization (Dobbs) removed federal abortion protections, people's views about alternative models of abortion care may have been impacted, yet research on this topic is limited.

Objective: To examine changes in national support for and personal interest in advance provision (AP) and over-the-counter (OTC) access to medication abortion.

Design, Setting, And Participants: Two nationally representative cross-sectional online surveys were administered to a market research firm's panel members who were assigned female at birth (AFAB) and aged 15 to 49 years from December 2021 to January 2022 (before Dobbs) and June to July 2023 (after Dobbs).

Amplitude and frequency of human gait synchronization with a machine oscillator system.

Humans sometimes synchronize their steps to mechanical oscillations in the environment (e.g., when walking on a swaying bridge or with a wearable robot).

Imagining Coat-Hangers and Pills: A Qualitative Exploration of Abortion Beliefs and Attitudes in Hostile Policy Contexts in the United States.

Objective: We explored awareness of and attitudes about the safety of various methods people use to attempt to end a pregnancy without medical assistance, which we refer to in this study collectively as self-managed abortion (SMA).

Methods: In 2020, we invited individuals living in eight United States (US) states considered "hostile" to abortion rights or with a history of criminalizing abortions performed outside the formal healthcare system to participate in semi-structured telephone interviews regarding their attitudes toward these practices. We analyzed coded transcripts for content and themes.
