This article examines the ethics of research design and the initiation of a study (e.g., recruitment of participants) involving refugee participants.

A single generation in the wild increases fitness for descendants of hatchery-origin Chinook salmon ().

Reintroduction is an important tool for the recovery of imperiled species. For threatened Pacific salmonids ( spp.) species, hatchery-origin (HOR) individuals from a nearby source are often used to reestablish populations in vacant, historically occupied habitat.

Demographic patterns of walleye () reproductive success in a Wisconsin population.

Harvest in walleye fisheries is size-selective and could influence phenotypic traits of spawners; however, contributions of individual spawners to recruitment are unknown. We used parentage analyses using single nucleotide polymorphisms to test whether parental traits were related to the probability of offspring survival in Escanaba Lake, Wisconsin. From 2017 to 2020, 1339 adults and 1138 juveniles were genotyped and 66% of the offspring were assigned to at least one parent.

Surface Versus Bulk State Transitions in Inkjet-Printed All-Inorganic Perovskite Quantum Dot Films.

The anion exchange of the halides, Br and I, is demonstrated through the direct mixing of two pure perovskite quantum dot solutions, CsPbBr and CsPbI, and is shown to be both facile and result in a completely alloyed single phase mixed halide perovskite. Anion exchange is also observed in an interlayer printing method utilizing the pure, unalloyed perovskite solutions and a commercial inkjet printer. The halide exchange was confirmed by optical absorption spectroscopy, photoluminescent spectroscopy, X-ray diffraction, and X-ray photoemission spectroscopy characterization and indicates that alloying is thermodynamically favorable, while the formation of a clustered alloy is not favored.

Evaluating sources of bias in pedigree-based estimates of breeding population size.

Applications of genetic-based estimates of population size are expanding, especially for species for which traditional demographic estimation methods are intractable due to the rarity of adult encounters. Estimates of breeding population size (N ) are particularly amenable to genetic-based approaches as the parameter can be estimated using pedigrees reconstructed from genetic data gathered from discrete juvenile cohorts, therefore eliminating the need to sample adults in the population. However, a critical evaluation of how genotyping and sampling effort influence bias in pedigree reconstruction, and how these biases subsequently influence estimates of N , is needed to evaluate the efficacy of the approach under a range of scenarios.

RAD-tag and mitochondrial DNA sequencing reveal the genetic structure of a widespread and regionally imperiled freshwater mussel, (Bivalvia: Unionidae).

is a species of freshwater mussel native to the Mississippi River and Laurentian Great Lakes-St. Lawrence River drainages of North America. This mussel has experienced population declines across large parts of its distribution and is imperiled in many jurisdictions.

Differential Roles of Actin Crosslinking Proteins Filamin and α-Actinin in Shear Flow-Induced Migration of .

Shear flow-induced migration is an important physiological phenomenon experienced by multiple cell types, including leukocytes and cancer cells. However, molecular mechanisms by which cells sense and directionally migrate in response to mechanical perturbation are not well understood. social amoeba, a well-established model for studying amoeboid-type migration, also exhibits directional motility when exposed to shear flow, and this behavior is preceded by rapid and transient activation of the same signal transduction network that is activated by chemoattractants.

Modeling of Covid-19 trade measures on essential products: a multiproduct, multicountry spatial price equilibrium framework.

In this paper, we develop a unified variational inequality framework in the context of spatial price network equilibrium problems that handles multiple products with multiple demand and supply markets in multiple countries as well as multiple transportation routes. The model incorporates a plethora of distinct trade measures, which is particularly important in the pandemic, as PPEs and other essential products are in high demand, but short in supply globally. In the model, product flows as well as prices at the supply markets and the demand markets in different countries are variables that allows us to seamlessly introduce various trade measures, including tariffs, quotas, as well as price floors and ceilings.

Gendered Massacres: Examining the Effects of Cultural and Structural Gender Inequality on the Incidence of Mass Public Shootings.

With nearly 97% of incidents within the past 40 years committed by men, mass public shootings are a gendered social problem. Yet, empirical research on this phenomenon largely neglects gender hierarchy and cultural factors as predictors, in favor of individual- and event-level characteristics. Despite calls from scholars to place masculinity and threats to patriarchal hegemony at the center of analyses, no empirical studies to our knowledge have examined the role of gender inequality in mass public shootings.

Design and Evaluation of the Environmental Outreach Activity for Middle School Students.

The design and development of an outreach activity targeted at 6th grade middle school students, which aims to determine the level of phosphate in samples of water from nearby lakes and streams, are detailed. Several parameters were noted as key to the successful implementation of this activity in a school setting and to it being well-received by both students and teachers. These include the hands-on nature of the experiment, the use of professional scientific equipment and protocols, and the relevance to everyday life and nearby societal issues.

Inkjet Printing All Inorganic Halide Perovskite Inks for Photovoltaic Applications.

A method for synthesizing photoactive inorganic perovskite quantum dot inks and an inkjet printer deposition method, using the synthesized inks, are demonstrated. The ink synthesis is based on a simple wet chemical reaction and the inkjet printing protocol is a facile step by step method. The inkjet printed thin films have been characterized by X-ray diffraction, optical absorption spectroscopy, photoluminescent spectroscopy, and electronic transport measurements.

Understanding Intimate Partner Violence in the Asian Communities in America: A Systematic Review.

The goal of this study is to provide a systematic review of empirically based journal articles published between 2006 and 2016 that address intimate partner violence (IPV) among Asian communities in the United States. We analyzed 57 peer-reviewed journal articles published in English. Most studies employed quantitative research designs that were cross-sectional in nature and focused on examining the statistical relationships between variables.

Females in the forefront: time-based intervention effects on impulsive choice and interval timing in female rats.

Impulsive choice has been implicated in substance abuse, gambling, obesity, and other maladaptive behaviors. Deficits in interval timing may increase impulsive choices, and therefore, could serve as an avenue through which suboptimal impulsive choices can be moderated. Temporal interventions have successfully attenuated impulsive choices in male rats, but the efficacy of a temporal intervention has yet to be assessed in female rats.

Inkjet printable-photoactive all inorganic perovskite films with long effective photocarrier lifetimes.

Photoactive perovskite quantum dot films, deposited via an inkjet printer, have been characterized by x-ray diffraction and x-ray photoelectron spectroscopy. The crystal structure and bonding environment are consistent with CsPbBr perovskite quantum dots. The current-voltage (I-V) and capacitance-voltage (C-V) transport measurements indicate that the photo-carrier drift lifetime can exceed 1 ms for some printed perovskite films.

Targeted neurogenesis pathway-based gene analysis identifies ADORA2A associated with hippocampal volume in mild cognitive impairment and Alzheimer's disease.

Alzheimer's disease (AD) patients display hippocampal atrophy, memory impairment, and cognitive decline. New neurons are generated throughout adulthood in 2 regions of the brain implicated in AD, the dentate gyrus of the hippocampus and the subventricular zone of the olfactory bulb. Disruption of this process contributes to neurodegenerative diseases including AD, and many of the molecular players in AD are also modulators of adult neurogenesis.

Body mass in wild bearded capuchins, (Sapajus libidinosus): Ontogeny and sexual dimorphism.

Body mass is fundamental for understanding growth, health, and aspects of life history but records of body mass are rarely available for wild primates. We documented the body mass of all individuals in a group of wild bearded capuchin monkeys (Sapajus libidinosus) at annual intervals for seven consecutive years. Sexual dimorphism in body mass was more pronounced than reported in the literature for adults in this genus: females in our sample were relatively light (average 2.

Orthographic, phonologic, and semantic processing in reading disabled and nondisabled subjects.

In this study the confusability paradigm of Byrne and Shea and Waterman and Lewandowski was modified to include an orthographic condition made possible by presenting stimuli visually rather than aurally. The confusability tasks included a pseudoword-recognition task with only phonologic and orthographic information available for coding and a word-recognition task with phonologic, semantic, and orthographic information available for coding. 20 poor and 20 good readers (13 to 18 years of age) were asked to report whether stimuli had been presented a second time in two continuous lists (pseudoword and word).
