Generalized sequential normal compactness and weak differentiabilities
No full textWe study the generalized sequential normal compactness in variational analysis and establish characterizations of the property of graphs of weakly differentiable mappings between Banach spaces, as well as calculus rules involving such functions
Cultural diversity: an impetus to economic growth – under what conditions?
No full textRealizing cultural diversity’s impact on regional entrepreneurial activity has become crucial for scholars and policymakers. As a step in this direction, this study integrates insights from creative cognitive psychology and the knowledge spillover theory of entrepreneurship to examine this effect and the boundary conditions explaining it. Based on a six-year multi-sourced panel dataset for the 50 U.S. states, the analyses support the proposed arguments in that they indicate that cultural diversity is positively associated with entrepreneurial activity, and this relationship is moderated by regional immigration policy and regulatory framework. Specifically, the effect of cultural diversity on entrepreneurship is more substantial when a region’s immigration policy climate is more inclusionary than exclusionary. In addition, this relationship is also more robust when a region’s regulatory policy is more conscientious than more lax. These findings make novel contributions to our knowledge of how and when contextual conditions regulate (i.e. stimulate or hinder) the effect of cultural diversity on entrepreneurship. The manuscript draws vital implications for policymakers

The Incarcerated One-Shot: Applying Critical Pedagogy to Support Information Literacy Skill Development in Higher Education
No full text“He understands how I work and how I function”: Math teacher actions that promote autonomy among students with LDs and/or EBDs
No full textGuided by Self-Determination Theory, we conducted a case study of a high school math teacher nominated by students with disabilities as one who enhanced their learning. Using a combination of interviews and classroom observations, we explored the specific strategies that the teacher used to promote perceived autonomy among students with learning disabilities (LDs) and emotional-behavioral disorders (EBDs). The literature offers extensive evidence for the benefits of autonomy-supportive teacher practice, but much of the work was conducted without explicit inclusion of students with LDs and/or EBDs. Our analyses demonstrated that many of the practices captured in this research also worked to support the psychological needs of students with LDs and/or EBDs who participated in this study. Additionally, our case study teacher engaged in two additional strategies that are not currently represented in that body of evidence. As such, we discuss implications for practice and future directions for research
Patterns of \u3ci\u3eGrewia\u3c/i\u3e (Malvaceae) diversity across geographical scales in Africa and Madagascar
No full textBackground and AimsQuantifying spatial species richness is useful to describe biodiversity patterns across broad geographical areas, especially in large, poorly known plant groups. We explore patterns and predictors of species richness across Africa in one such group, the palaeotropical genus Grewia L. (Malvaceae).
MethodsGrewia species richness was quantified by extracting herbarium records from GBIF and Tropicos and creating geographical grids at varying spatial scales. We assessed predictors of species richness using spatial regression models with 30 environmental variables. We explored species co-occurrence in Madagascar at finer resolutions using Schoener’s index and compared species range sizes and International Union for Conservation of Nature status among ecoregions. Lastly, we derived a trait matrix for a subset of species found in Madagascar to characterize morphological diversity across space.
Key ResultsGrewia species occur in 50 countries in Africa, with the highest number of species in Madagascar (93, with 80 species endemic). Species richness is highest in Madagascar, with ≤23 Grewia species in a grid cell, followed by coastal Tanzania/Kenya (≤13 species) and northern South Africa and central Angola (11 species each). Across Africa, higher species richness was predicted by variables related to aridity. In Madagascar, a greater range in environmental variables best predicted species richness, consistent with geographical grid cells of highest species richness occurring near biome/ecoregion transitions. In Madagascar, we also observe increasing dissimilarity in species composition with increasing geographical distance.
ConclusionsThe spatial patterns and underlying environmental predictors that we uncover in Grewia represent an important step in our understanding of plant distribution and diversity patterns across Africa. Madagascar boasts nearly twice the Grewia species richness of the second most species-rich country in Africa, which might be explained by complex topography and environmental conditions across small spatial scales
The role of social support in disarming the effects of racial microaggressions
No full textRacial microaggressions are a significant source of stress for people of color. This study identified two support message features for disarming the effects of racial microaggressions and tested reasons for their effectiveness. In a between-groups design, Black/African Americans (n = 387), and Asian Americans (n = 374) evaluated a support message crafted by a friend in response to one of six racial microaggressions. Participants perceived high person-centered, racial identity-affirming, and combination support messages as more effective and collective self-esteem enhancing than low quality message versions. Person-centered emotional support and combination messages were partly related to enhanced collective self-esteem through cognitive reappraisal and reattribution, while racial identity affirmation message quality was partly related to enhanced collective self-esteem through reattribution. Conditional process analyses determined that indirect effects were not contingent on participants’ race. Practical and theoretical implications of studying support messages to address racial microaggressions are discussed
