The Professional Identity of STEM Faculty as Instructors of Course-based Research Experiences.

The professional identity of scientists has historically been cultivated to value research over teaching, which can undermine initiatives that aim to reform science education. Course-Based Research Experiences (CRE) and the inclusive Research and Education Communities (iREC) are two successful and impactful reform efforts that integrate research and teaching. The aim of this study is to explicate the professional identity of instructors who implement a CRE within an established iREC and to explore how this identity contributes to the success of these programs.

When Inequity Leads to Boredom: An Experimental Study With University Students.

While theoretical connections between social inequity and boredom have been established, empirical evidence is lacking. Inequity aversion is important in this relationship. If individuals believe that the amount of work invested in pursuing an outcome has been unfairly devalued in relation to the investment of others, they may feel that their investment is greater than the outcome's worth.

The interactive roles of narrative processing and emotion negativity/lability in relation to autonomic coordination.

Emotion regulation (ER) is a multifaceted construct, involving behavioral, cognitive, and physiological processes. Although autonomic coordination is theorized to play a crucial role in adaptive functioning, few studies have examined how different individual and contextual factors together may contribute to such coordination. This study examined the joint influences of narrative processing and emotional negativity/lability (N/L) traits on the coordination of the sympathetic and parasympathetic nervous systems in a sample of 112 children, ages 8-12 years (M = 10.

Models of Classroom Assessment for Course-Based Research Experiences.

Course-based research pedagogy involves positioning students as contributors to authentic research projects as part of an engaging educational experience that promotes their learning and persistence in science. To develop a model for assessing and grading students engaged in this type of learning experience, the assessment aims and practices of a community of experienced course-based research instructors were collected and analyzed. This approach defines four aims of course-based research assessment - 1) Assessing Laboratory Work and Scientific Thinking; 2) Evaluating Mastery of Concepts, Quantitative Thinking and Skills; 3) Appraising Forms of Scientific Communication; and 4) Metacognition of Learning - along with a set of practices for each aim.

Yes, no, maybe so: Caregiver autonomy support, conversation context, and children's memory performance.

The extant literature on the use of autonomy support during caregiver-child conversations has focused primarily on conversations about fun, shared experiences, with limited consideration of unshared experiences or attention toward the role of conversation context. The present study examined how autonomy support, conversation context, and child age interact to predict 3-to-5-year-old children's disclosure of accurate information when discussing an unshared past event with their caregiver and an experimenter. Dyads ( = 111) were recruited from two locations (Miami, Florida and Orange County, California) by research recruitment firms.

Communicating beyond the information given can make the communicator's attitudes toward a social group more extreme.

Three experiments tested how communicating attributes of initially liked or disliked groups might create more extreme attitudes. We gave non-neutral participants information about previously unknown groups and asked them to write social media posts describing the group to others. Participants who wrote social media posts to friends (Experiment 1, = 332) or undecided strangers (Experiments 2 and 3, s = 113 and 816) exaggerated and elaborated on initial information, subsequently reporting more extreme attitudes.

Prophages Present in Influence Bacterial Virulence, Antibiotic Resistance, and Genomic Rearrangements.

Antibiotic resistance and virulence are common among bacterial populations, posing a global clinical challenge. The bacterial species , an infectious agent in clinical environments, has shown increasing rates of antibiotic resistance. Viruses that integrate as prophages into could be a potential cause of this pathogenicity, as they often contain antibiotic resistance or virulence factor gene sequences.

XUV-Initiated Dissociation Dynamics of Molecular Oxygen (O).

We performed a time-resolved spectroscopy experiment on the dissociation of oxygen molecules after the interaction with intense extreme-ultraviolet (XUV) light from the free-electron laser in Hamburg at Deutsches Elektronen-Synchrotron. Using an XUV-pump/XUV-probe transient-absorption geometry with a split-and-delay unit, we observe the onset of electronic transitions in the O cation near 50 eV photon energy, marking the end of the progression from a molecule to two isolated atoms. We observe two different time scales of 290 ± 53 and 180 ± 76 fs for the emergence of different ionic transitions, indicating different dissociation pathways taken by the departing oxygen atoms.

Climbing parrots achieve pitch stability using forces and free moments produced by axial-appendicular couples.

During vertical climbing, the gravitational moment tends to pitch the animal's head away from the climbing surface and this may be countered by (1) applying a correcting torque at a discrete contact point, or (2) applying opposing horizontal forces at separate contact points to produce a free moment. We tested these potential strategies in small parrots with an experimental climbing apparatus imitating the fine branches and vines of their natural habitat. The birds climbed on a vertical ladder with four instrumented rungs that measured three-dimensional force and torque, representing the first measurements of multiple contacts from a climbing bird.

Hesperidin Promotes Osteogenesis and Modulates Collagen Matrix Organization and Mineralization In Vitro and In Vivo.

This study evaluated the direct effect of a phytochemical, hesperidin, on pre-osteoblast cell function as well as osteogenesis and collagen matrix quality, as there is little known about hesperidin's influence in mineralized tissue formation and regeneration. Hesperidin was added to a culture of MC3T3-E1 cells at various concentrations. Cell proliferation, viability, osteogenic gene expression and deposited collagen matrix analyses were performed.

Duchenne Smiles as Honest Signals of Chronic Positive Mood.

Chronic positive mood (CPM) has been shown to confer a wide variety of social, functional, and health benefits. Some researchers have argued that humans evolved to feel CPM, which explains why most people report better than neutral mood (the "positivity offset bias") and why particularly happy people have particularly good outcomes. Here, we argue that the Duchenne smile evolved as an honest signal of high levels of CPM, alerting others to the psychological fitness of the smiler.

A qualitative review of cannabis stigmas at the twilight of prohibition.

Background: As laws change and cannabis use increases, it is worthwhile to take a rich account of cannabis stigmas in society, and this review identifies a disjunction between quantitative investigations on cannabis users and qualitative investigations on the same population. This is also the first attempt to explicate cannabis stigmas as they manifest on multiple analytical levels. Following brief explanations of the normalization hypothesis and the concept of stigma, this review is organized between structural (macro) stigmas, social (meso) stigmas, and personal (micro) stigmas.

Using Storytelling to Teach Effective Followership.

This chapter examines the craft of storytelling for the purpose of developing followers and exploring leader-follower transitions, while offering storytelling methods, classroom activities, and critical components of crafting a story. Through stories about the American Civil Rights icon, Mrs. Rosa Parks, and an unfamiliar Civil Rights activist, Sister Madeline Dorsey, a humble leader turned effective follower, it is possible to more easily appreciate the reflexive transition of follower to leader and leader to follower.

The Relationship Between Food Deserts, Farmers' Markets, and Food Assistance Programs in Hawai'i Census Tracts.

Due to inadequate resources and limited access to healthy foods, residents who live in food deserts struggle to maintain a healthful diet. Living in a food desert increases the risk of developing diet-related chronic diseases such as obesity. Local farmers' markets serve as community-level interventions, bringing healthy food options to food deserts.

Exposure to Violence and Posttreatment Substance Use Among Patients With Opioid Use Disorder.

Exposure to violence can lead to a dramatic increase in the likelihood of the development of a substance use disorder (SUD). Given the overlap between the two, substance use for survivors of violence, then, can be a coping mechanism to manage the traumatic effects of abuse and persistent use can evolve into a diagnosable SUD. This study was designed to examine the posttreatment substance use among adults who have a history of exposure to violence and sought treatment for opioid use disorder.

The relationship between food deserts, farmers' markets, Nutrition Benefits, and health in Delaware census tracts; 2017.

Food desert residents struggle to maintain a well-balanced, nutritious diet, increasing their risk of obesity and diabetes. Farmers' markets are a community-level intervention, bringing healthy food to food deserts. This study explores the relationship between food deserts, farmers' market location, the prevalence of obesity and diabetes, and the availability of Nutrition Benefit Programs (NBPs) in Delaware.

Does It Take a Village? Migration among Rural South African Youth.

In a rural African context, the saying, "it takes a village to raise a child," suggests that community characteristics are substantially important in children's lives as they transition to adulthood. Are these contextual factors also related to youth migration? Demographers are uncertain about how community characteristics improve our understanding of an individual's propensity to migrate, beyond individual and household factors. In many low and middle-income country settings, youth become migrants for the first time in their lives to provide access to resources that their families need.

The Genome Solver Project: Faculty Training and Student Performance Gains in Bioinformatics.

Bioinformatics brings together biology, mathematics, statistics, and computer science to analyze biological sequence information. Anyone with a computer, access to the Internet, and basic training in this field can contribute to genomics research. Yet many biology faculty feel they lack training in the use of bioinformatics tools and therefore include little bioinformatics content in their courses.
