Survey researchers increasingly recognize the need to update their gender questions to recognize the existence of transgender and nonbinary people. In this research note, we evaluate changes to the Canadian Election Study (CES) gender questions from 2019 to 2021. Our analyses suggest researchers should add “nonbinary” as a close-ended option and an open-ended response option to gender identity questions. They also suggest that researchers should not include “transgender” in a separate, mutually exclusive response option alongside men and women in gender identity questions but instead identify transgender men and women through a follow-up question. These recommendations can help guide the design of future surveys.

Today, few political news outlets receive universally favorable evaluations from the American public. In retaining broad public approval, local media remain a notable exception that is important to understand. We consider the durability of local news trust to criticism from politicians, focusing on Republican elites because they generally are more willing to attack the media than Democrats. In a survey experiment, we find that exposure to a Republican politician’s attack on a local newspaper dramatically reduces the public’s trust in and intent to use local news. This attack is particularly effective among Republicans, although it also leads Democrats and Independents to negatively shift their views of the local newspaper. Among those exposed to elite criticism of local news, overall trust and partisan divides between Republicans and Democrats resemble those for national media. This shows that the credibility of local news depends on the absence of elite criticism rather than resilience to it.

Evidence-based insertion and maintenance bundles are effective in reducing the incidence of central line-associated bloodstream infections (CLABSI) in intensive care unit (ICU) settings. We studied the adoption and compliance of CLABSI prevention bundle programs and CLABSI rates in ICUs in a large network of acute care hospitals across Canada.

Children acquiring Japanese differ from those acquiring English with regard to the rate at which verbs are learned (Fernald & Morikawa, 1993). One possible explanation is that Japanese caregivers use verbs in referentially transparent contexts, which facilitate the form-meaning link. We examined this hypothesis by assessing differences in verb usage by Japanese and American caregivers during dyadic play with their infants (5-22 months). We annotated verb-containing utterances for elements associated with referential transparency and compared across groups. Contrary to our hypotheses, we found that Japanese caregivers used verbs in fewer referentially transparent contexts than American caregivers, or did not significantly differ from American caregivers, depending on the measure. These findings cast doubt on cross-cultural differences in referential transparency between Japanese and American child-directed input.

The “gender gap” in voting is one of the most well-documented findings in survey research across democracies. However, gender gap research has traditionally assumed that everyone is either a man or a woman, which does not account for the growing number of people who identify as nonbinary. How do nonbinary people differ from men and women in their party identification and voting behavior? We answer this question using data from the 2021 Canadian Election Study online panel, which has a large enough subsample of nonbinary respondents to identify gaps in party identification and voting behavior. Nonbinary people are much less likely to identify with and vote for the Liberal Party or Conservative Party and much more likely to identify with and vote for the social democratic New Democratic Party (NDP) than both men and women. Many of these gaps persist even when restricting the analysis to LGBTQ respondents, adjusting for demographic variables that predict nonbinary identity, and adjusting for issue attitudes. Nonbinary people’s distinctiveness from men and women suggests that researchers need to add nonbinary response options to gender questions and, wherever possible, incorporate nonbinary people into analyses of gender and politics.

Phenological studies for Cuban bulrush [Oxycaryum cubense (Poepp. & Kunth) Lye] have been limited to the monocephalous form in Lake Columbus (Mississippi). Accordingly, there is little available information on potential phenological differences among O. cubense forms (monocephalous vs. polycephalous) and populations in other geographic locations in the United States. Therefore, seasonal patterns of biomass and starch allocation in O. cubense were quantified from two populations in Lake Columbus on the Tennessee-Tombigbee Waterway in Mississippi (monocephalous), two populations from Lake Martin in Louisiana (polycephalous), and two populations from Orange Lake in Florida (polycephalous). Monthly samples of O. cubense inflorescence, emergent, and submersed tissue were harvested from two plots per state from October 2021 to September 2022. During monthly data collection, air temperature and photoperiod were recorded. Starch allocation patterns were similar among all sites, with starch storage being less than 1.5% dry weight for all plant tissues. Biomass was greatest in Lake Columbus (monocephalous; 600.7 g dry weight [DW] m−2) followed by Lake Martin (polycephalous; 392.3 g DW m−2) and Orange Lake (polycephalous; 233.85 g DW m−2). Peak inflorescence biomass occurred in the winter for the Lake Martin and Orange Lake populations and in the summer for the Lake Columbus population. Inflorescence biomass in Lake Columbus had a positive relationship (r2 = 0.53) with warmer air temperatures. Emergent and submersed biomass generally had negative relationships with both photoperiod and temperature (r2 = 0.02 to 0.77) in all sites. Peak biomass was also negatively related to temperature and photoperiod. Results from this study indicate that there are differences in biomass allocation between the two growth forms of O. cubense and that growth can occur at temperatures below freezing. Low temperature tolerance may allow this species to expand its range farther north than previously suspected.

Medical researchers are increasingly prioritizing the inclusion of underserved communities in clinical studies. However, mere inclusion is not enough. People from underserved communities frequently experience chronic stress that may lead to accelerated biological aging and early morbidity and mortality. It is our hope and intent that the medical community come together to engineer improved health outcomes for vulnerable populations. Here, we introduce Health Equity Engineering (HEE), a comprehensive scientific framework to guide research on the development of tools to identify individuals at risk of poor health outcomes due to chronic stress, the integration of these tools within existing healthcare system infrastructures, and a robust assessment of their effectiveness and sustainability. HEE is anchored in the premise that strategic intervention at the individual level, tailored to the needs of the most at-risk people, can pave the way for achieving equitable health standards at a broader population level. HEE provides a scientific framework guiding health equity research to equip the medical community with a robust set of tools to enhance health equity for current and future generations.

In the summer of 2022, Tulane University, in collaboration with archaeologists from other institutions, began excavations at the site of Pompeii. The archaeological work was focused on Insula 14 of Region 1, located in the southeastern sector of the site. To overcome the challenges of recording a complex urban excavation, and of working with a collaborative team, we designed and implemented a unique workflow that combines paperless and 3D data-capture methods through the use of GIS technologies. The final product of our documentation workflow was a robust and easy-to-use online geodatabase where archaeologists can revisit, explore, visualize, and analyze each excavated context using virtual tools. We present our workflow for digitally documenting observational and spatial data in the field, and how we made these data available to project archaeologists during and after the field season. First, we describe the development of digital forms in ESRI's Survey123. Then, we explain our procedures for 3D documentation through SfM photogrammetric methods and discuss how we integrated the data and transformed it into an accessible format by using interactive dashboards and online 3D web scenes. Finally, we discuss the components of our workflow that are broadly applicable and that can easily be adapted to other projects.

OBJECTIVES/GOALS: An environmental scansoughtto understand research processes, areas for improvement, and opportunities for collaborative quality improvement (QI)across the Northwest Participant and Clinical Interactions Network (NW PCI). METHODS/STUDY POPULATION: NW PCI site champions were invited for semi-structured single and group Zoom-based interviews. Interviewers asked participants about local research processes, strengths and weaknesses, existing infrastructure to support QI, and interest in collaborative QI across the Network. Audio transcripts were coded using Dedoose and analyzed with deductive and inductive coding. RESULTS/ANTICIPATED RESULTS: Between February and April 2023, 10 interviews collected data from 7 research decision makers and 7 staff members across 7 sites. Most participants (n=13, 92%) agreed the diagram shown during the interview was representative of the local process. Organizations consistently identified strengths and weaknesses within the domains of study start-up, recruitment, budgets, and compliance. QI infrastructure was inconsistent (n=5, 36%) and all (n=14, 100%) saw potential for success in multisite QI initiatives to enhance efficiency. DISCUSSION/SIGNIFICANCE: NW PCI sites use similar processes, share common strengths and weaknesses, and universally reported interest in collaborating on QI. Study startup was reported as both a strength and weakness within the same organization, requiring unpacking of key elements before pursuing QI initiatives.

OBJECTIVES/GOALS: Vanishing White Matter Disease (VWM), is a childhood neurodegenerative leukodystrophy that presents with motor deficits, neurologic decline, and seizures leading to death.There are no treatments. Herein we investigate adeno-associated virus serotype 9 (AAV9) gene addition therapy for VWM. METHODS/STUDY POPULATION: To serve as a baseline for disease correction, we characterized the severe VWM Eif2b5I98M murine model with clinically relevant readouts including motor function, gait mapping and myelin loss through magnetic resonance imaging (MRI). Molecular characterization through the identification of biomarkers was also investigated. To provide targeted disease correction, we designed four gene replacement constructs to drive the rapeutic EIF2B5 expression in astrocytes—a critical cell type for VWM pathology. We are currently evaluating our AAV vectors in two murine VWM models, Eif2b5R191H and Eif2b5I98M, and are monitoring disease progression using traditional and clinically relevant readouts. RESULTS/ANTICIPATED RESULTS: The I98M mice display significant mobility loss, ataxic gait, and demyelination. Molecular characterization also indicates that the integrated stress response is significantly dysregulated, supporting the classic VWM phenotype. Our previous biodistribution study confirmed our ability to efficiently target astrocytes using varying iterations—including one novel—of the glial fibrillary acidic protein (GFAP) promoter. Our data suggests that targeting astrocytes with gene addition delays disease onset, partially rescues motor function, and attenuates myelin loss. Survival of the AAV9-gfaABC(1)D-EIF2B5 treated I98M mice is also significantly increased (p<0.0001), currently with a 2-fold extension in life expectancy. DISCUSSION/SIGNIFICANCE: Overall, we anticipate emergence of a lead astrocyte-targeted gene therapy candidate in which the data will be strengthened through the evaluation of clinically relevant measures in two murine models of disease, allowing fortimely translation to the clinic.

OBJECTIVES/GOALS: The Institute of Translational Health Science (ITHS) Remote Technologies for Research Reference Center (REMOTECH) aims to support researchers using remote technologies. Understanding barriers specifically for engagement of diverse populations is critical to improve equitable access and increase diverse participation in research. METHODS/STUDY POPULATION: We conducted semi-structured interviews with researchers (N=30) within the WWAMI (Washington, Wyoming, Alaska, Montana and Idaho) region, identified through participation in a previous survey as well as those known to have previously implemented remote technologies at ITHS institutions. We solicited specific concerns regarding equity, diversity, and inclusion (EDI) related to remote research participant recruitment, retention, and implementation, as well as outcomes and potential solutions. Interview transcripts were coded, summarized, and emerging themes were identified. RESULTS/ANTICIPATED RESULTS: The pandemic necessitated a shift to the use of remote research engagement strategies. Our interview findings show that researchers have a desire to: increase diversity through remote engagement options; decrease participant burden; and understand and include strategies that advance equity, diversity, and inclusion (EDI) efforts. While geographic diversity was positively impacted by the use of remote technologies, significant barriers and challenges currently exist in the use of remote technologies with respect to other types of diversity, for example access to technologies and limited financial resources. DISCUSSION/SIGNIFICANCE: Remote technologies in research could increase diversity, but interviewees shared barriers and challenges that prevent that from happening. Researchers would benefit from equity-oriented digital literacy resources to use with diverse populations. Such tools can also be used to guide study design/procedures, materials, and processes.

Classic political behavior studies assert that childhood socialization can contribute to later political orientations. But, as adults consider how to introduce children to politics, what shapes their decisions? We argue socialization is itself political with adults changing their socialization priorities in response to salient political events including social movements. Using Black Lives Matter (BLM) protests and race socialization as a case, we show the summer 2020 information environment coupled movement-consistent concepts of race with child-rearing guidance. A survey of white parents after the summer activism suggests that many—but especially Democrats and those near peaceful protest epicenters—prioritized new forms of race socialization. Further, nearly 2 years after the protests’ height, priming BLM changes support for race-related curricular materials among white Americans. Our work casts political socialization in a new light, reviving an old literature, and has implications for when today’s children become tomorrow’s voters.

Limited analyses based on national samples have assessed whether early attention-deficit/hyperactivity disorder (ADHD) symptoms predict later internalizing and externalizing symptoms in youth and the influence of sex and pubertal timing on subsequent psychiatric symptoms. This study analyzed data (n = 2818) from the Environmental influences on Child Health Outcomes Program national cohort. Analyses used data from early childhood (mean age = 5.3 years) utilizing parent-reported ADHD symptoms to predict rates of internalizing and externalizing symptoms from late childhood/adolescence (mean age = 11.9 years). Within a subsample age at peak height velocity (APHV) acted as a proxy to assess pubertal timing from early childhood (mean age = 5.4 years) to adolescence (mean age = 12.3 years). Early-childhood ADHD symptoms predicted later psychiatric symptoms, including anxiety, depression, aggressive behavior, conduct problems, oppositional defiant disorder, and rule-breaking behavior. Earlier APHV was associated with increased Conduct Disorder symptoms from late childhood to adolescence for females only. A stronger relation between ADHD symptoms and later aggression was observed in females with earlier APHV, whereas this same pattern with aggression, conduct problems and depression was observed in males with later APHV. Clinicians should consider that both young girls and boys with elevated ADHD symptoms, particularly with off-set pubertal timing, may be at risk for later psychiatric symptoms.
