Ground electronic state description of thiourea coordination in homoleptic Zn, Ni and Co complexes using sulfur K-edge X-ray absorption spectroscopy.

Sulfur K-edge X-ray absorption spectroscopy (XAS) was employed to experimentally characterize the coordinative bond between the thiourea (TU) or thiocarbamide ligand and transition metal (TM) ions Zn, Co and Ni in distorted tetrahedral and octahedral homoleptic coordination environments. Comparisons of XAS spectra of the free TU ligand and [Zn(TU)], [Co(TU)] and [Ni(TU)] complexes clearly identify spectral features unique to TM-S(TU) bonding. Quantitative analysis of pre-edge intensities describes the covalency of Ni-S(TU) and Co-S(TU) bonding to be at most 21% and 9% as expressed by the S 3p contributions per TM 3d electron hole.

Associations between parenting representations and behavior among young mothers and mothers with opioid use disorder.

Mothers' representations reflect how they experience their child and their relationship, and can guide parenting behavior. While studies of representations typically focus on infancy, this study examines associations between mothers' representations and behavior with their preschoolers using two samples: young mothers (n = 201; 42% African American, 42% Latina, 8% European-American, 8% multi-ethnic; M  = 32 months) and mothers in treatment for opioid use disorder (OUD; n = 150; 100% African American; M  = 49 months). This study aims to identify the distribution of representations within these populations, differences in parenting between mothers classified with balanced and non-balanced representations, and distinct parenting behaviors associated with distorted and disengaged representations.

Loss of Elp1 perturbs histone H2A.Z and the Notch signaling pathway.

Elongator dysfunction is increasingly recognized as a contributor to multiple neurodevelopmental and neurodegenerative disorders including familial dysautonomia, intellectual disability, amyotrophic lateral sclerosis, and autism spectrum disorder. Although numerous cellular processes are perturbed in the context of Elongator loss, converging evidence from multiple studies has resolved Elongator's primary function in the cell to the modification of tRNA wobble uridines and the translational regulation of codon-biased genes. Here we characterize H2a.

The Effect of Set Configuration and Load on Post-Activation Potentiation on Vertical Jump in Athletes.

The aim of this study was to compare the effect of post-activation potentiation (PAP) on countermovement jump (CMJ) using different set configurations and loads on conditioning activity (CA) in highly trained athletes. Sixteen national level swimmers participated in this study and performed a total of six visits to the laboratory. The first session was used for familiarization, the second session was utilized to determine five repetitions maximum (RM) in the half squat (HS), and the following four visits consisted of four CA protocols performed in a counterbalanced order.

The Bakken Blind Field: Investigating Planetary Urbanization and Opaqueness in the Oil and Gas Fields of Eastern Montana, USA.

This work advances the critical urban studies literature on "planetary urbanization" by emphasizing the everyday struggles experienced by the people who live in and through planetary transformations. Specifically, we empirically investigated people in Eastern Montana who experienced the intensive and extensive oil and gas production of the Bakken Boom via interview and survey data. In the process, we interrogated Henri Lefebvre's notion of the "blind field," and conclude that what we call the "Bakken blind field" represents a deeply engrained "habit of the mind" that functions for the energy industry as a means of neutralizing the transformative potential that always lurks in response to persistent socio-environmentally exploitative practices.

How Social Media Comments Inform the Promotion of Mask-Wearing and Other COVID-19 Prevention Strategies.

Current COVID-19 messaging efforts by public health departments are primarily informational in nature and assume that audiences will make rational choices in compliance, contradicting extensive research indicating that individuals make lifestyle choices based on emotional, social, and impulsive factors. To complement the current model, audience barriers to prevention need to be better understood. A content analysis of news source comments in response to daily COVID-19 reports was conducted in Montana, one of the states expressing resistance to routine prevention efforts.

Advancements and critical steps for statistical analyses in blood pressure response to resistance training in hypertensive older women: a methodological approach.

Background: Repeated measures analysis of covariance and three-way analysis of variance with repeated measures are common statistical methods. For a valid interpretation of blood pressure (BP) response to exercise, a variety of additional statistical methods must be implemented. Four additional statistical methods are presented: technical error of measurement (SEM), smallest real difference (SRD), magnitude-based inference and mixed effect modeling technique (MEM).

Impact of travel time uncertainties on modeling of spatial accessibility: a comparison of street data sources.

GIS-based spatial access measures have been used extensively to monitor social equity and to help develop policy. However, inherent uncertainties in the road datasets used in spatial access estimates remain largely underreported. These uncertainties might result in unrecognized biases within visualization products and decision-making outcomes that strive to improve social equity based on seemingly egalitarian accessibility metrics.

Insights from the Inclusive Environments and Metrics in Biology Education and Research Network: Our Experience Organizing Inclusive Biology Education Research Events.

In contrast to efforts focusing on improving inclusion in STEM classrooms from kindergarten through undergraduate (K-16), efforts to improve inclusion in scientific meetings and conferences, important hubs of STEM culture, are more recent. Markers of inclusion that are sometimes overlooked at these events can include the composition of panels, how workshops are run, the affordability of conferences, and various other mechanisms that maintain pre-existing hierarchies and norms that limit the participation of early-career researchers and individuals of minoritized cultural, linguistic, and economic backgrounds. The Inclusive Environments and Metrics in Biology Education and Research (iEMBER) network coordinates efforts of researchers from many fields interested in diversity and inclusion in biology education.

Diet quality among pregnant women in the Navajo Birth Cohort Study.

Proper nutrition during pregnancy is vital to maternal health and fetal development and may be challenging for Navajo Nation residents because access to affordable and healthy foods is limited. It has been several decades since reported diet quality during pregnancy was examined on Navajo Nation. We present the first study to estimate iodine intake and use the Healthy Eating Index (HEI-2015) to assess maternal diet quality among pregnant women in the Navajo Birth Cohort Study (NBCS).
