Invasive Species Terminology: Standardizing for Stakeholder Education

The excessive number of terms associated with invasive species, and their often incorrect usage, hinders stakeholder education about the threats of invasive species. Here we introduce seven terms (native, nonnative, introduced, established, invasive, nuisance, and range change) that are applicable across invasive taxa, understandable, typically interpreted correctly, and useful for describing most situations regarding invasive species. We also list six terms to avoid (native invasive, invasive exotic, invasive weed, alien, foreign, and nonindigenous) that create confusion via their misuse and misinterpretation. The terms we propose will increase understanding, thereby promoting behavior changes aimed at limiting the negative impacts of invasive species

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

When Race and Class Both Matter: The Relationship between Socioeconomic Diversity, Racial Diversity, and Student Reports of Cross–Class Interaction

This paper delves into a facet of socioeconomic diversity relatively unaddressed in the literature: student reports of cross-class interaction ("reported CCI"). Previous research has found that student interaction across social class is a significant predictor of cross-racial interaction, but it is unknown whether the actual socioeconomic heterogeneity of a student body is significantly related to reported CCI. We use hierarchical linear modeling to identify predictors of reported CCI in the 2003 Freshman/2007 College Student Survey from the UCLA Higher Education Research Institute. In the final model, students who attended more socioeconomically diverse institutions and more racially diverse institutions reported higher levels of CCI. Findings suggest that reported CCI is linked to the actual socioeconomic heterogeneity of a student body. Measures of racial diversity (percent of students of color and diversity engagement), both at the institutional and student level, also predicted reported CCI. Thus, reported CCI is likely influenced by the racial diversity of a student body and other aspects of the campus racial climate, in addition to socioeconomic diversity. Implications for campus climate, diversity, and equity research are discussed

Progestins Activate the AKT Pathway in Leiomyoma Cells and Promote Survival

Context: Progesterone has been associated with promoting growth of uterine leiomyomas. The mechanisms involved remain unclear

Leaders and subgroups: One of us or one of them?

In two experiments we examined responses to nomination of a leader from within a super ordinate group that comprised subgroups. In Experiment 1, the leader was aligned with the participant's subgroup (in group) or the other subgroup (out group), or the leader was non-aligned, belonging to both or neither subgroup. Results indicated that nomination of a leader made subgroup identity salient relative to a no leader control. Respondents expected aligned leaders, especially out group leaders, to favor their own subgroup and those with an out group leader were more biased themselves. In Experiment 2, members evaluated in group and out group leaders in contexts that emphasized intergroup competition (at the level of the super ordinate group) or intergroup competition (between the subgroups). Members were more satisfied with the leader in the inter group context, although context did not attenuate differences in evaluations of in group and out group leaders. Implications for leadership in groups and organizations are discussed

Historas (co) movedoras: Historia Oral e estudos de migrac?o

This article intends to review the contribution which oral history has made to migration studies over the last quarter century, mainly between Britain and Australia. The title "moving stories" in an useful pun about the oral history of migration because is centered on the physical experience of movement between places, as well as is deeply moving for the narrator and for his or her audience
