Active, Prolonged Engagement (APE) and Interactive Lecturing Help Students Learn

Instructors in two sections of developmental psychology compared an interactive lecture session with a session that utilized active, prolonged engagement (APE) - a concept from the museum world. Results revealed that student were equally engaged with both kinds of class structures and learned equally in both structures

Library Instruction vs. Information Competency: It\u27s Not Just Bibliographic Instruction Anymore

The Agriculture Library at the University of Kentucky has offered library instruction in some form for the past 23 years. The program began in 1974 with the Library Literacy program that offered on demand workshops, an undergraduate for-credit course, graduate workshops and programs to extension personnel. By 1988 the program had moved into a library literacy program that was proactive, provided individualized presentations, and provided a mix of electronic and paper sources. This program gave way to the information literacy program of 1994 which expanded target groups and collaborated with other areas. A shift in the teaching emphasis in the College of Agriculture changed the way that library instruction was offered to the undergraduate students. The information literacy program of 1994 emphasized the ability to use the information system in general. Another shift is occurring and we are now moving into information competency where the goal is that the user becomes fully competent in the appropriate system for the appropriate use. To accomplish this the programs must be user driven, flexible, and assessment must be done to measure effectiveness

The globalization of angel investments. Bruegel Working Paper 2015/09, 1 September 2015

The last decade has seen a rapid expansion and deepening of the types of vehicles that fund start-up firms in the U.S. and worldwide. In particular, we have seen a growing role of angel groups and other more “individualistic” funding options for start-ups, such as super angels or crowd sourcing platforms. Authors seek to understand the nature and consequences of angel investments across a variety of geographies with varying levels of venture capital markets and other forms of risk capital. They ask whether angel investors improve the outcomes and performance of the start-ups they invest in. Furthermore we want to understand whether and how the types of firms that seek angel funding vary with the overall entrepreneurial ecosystem in a country. Authors examine the records of 13 angel investment groups based in 12 nations and with applicants for financing transactions from 21 nations, examining both the applicants that were considered and rejected and those that were funded. Key findings from the analysis are two-fold. First, angel investors have a positive impact on the growth of the firms they fund, their performance, and survival. Second, they find that the selection of firms that apply for angel funding is different across countries

Colorism Among Black Youth in the United States: An Examination of Impacts on Education

Black students with darker complexions experience a disproportionate application of exclusionary practices within educational settings (Crutchfield et al., 2022). This review seeks to highlight colorism’s impact on the Black community in the education system through examining the historical context of colorism, the connection between colorism and racism, and how colorism is manifested and perpetuated in contemporary society in the United States. “Antiblackness” is an enduring trait of the United States that has rooted and fixed itself to its school structures (Coles & Powell, 2019). Schools are inherently political in that they adhere to and perpetuate the dominant ideologies of society (Picower & Mayorga, 2015), essentially functioning as a microcosm of society. Colorism functions as an extension of antiblackness in its perpetuation of prejudice and discriminatory behavior against darker skinned individuals and those with more African phenotypes. Black students are mandated by state-driven compulsory education laws to attend school but may receive differential treatment on the basis of skin tone, facial feature, and hair texture variations with the ethnic group. Exclusionary practices restrict students’ access to the school environment and may lead to a diminished academic identity, a sense of invisibility, feelings of invalidation, and limited access to future opportunities. In this review, the need for interventions addressing colorism in educational settings will be discussed. Recommendations for future directions of colorism research are also discussed

The Globalization of Angel Investments: Evidence across Countries

This paper examines investments made by 13 angel groups across 21 countries. We compare applicants just above and below the funding cut-off and find that these angel investors have a positive impact on the growth, performance, and survival of firms as well as their follow-on fundraising. The positive impact of angel financing is independent of the level of venture activity and entrepreneur friendliness in the country. But we find that the development stage and maturity of start ups that apply for angel funding (and those that are ultimately funded) is inversely correlated with the entrepreneurship friendliness of the country, which may reflect self-censoring by very early stage firms who do not expect to receive funding in these environments

Failure to Preserve β-Cell Function With Mycophenolate Mofetil and Daclizumab Combined Therapy in Patients With New- Onset Type 1 Diabetes

OBJECTIVE This trial tested whether mycophenolate mofetil (MMF) alone or with daclizumab (DZB) could arrest the loss of insulin-producing β-cells in subjects with new-onset type 1 diabetes. RESEARCH DESIGN AND METHODS A multi-center, randomized, placebo-controlled, double-masked trial was initiated by Type 1 Diabetes TrialNet at 13 sites in North America and Europe. Subjects diagnosed with type 1 diabetes and with sufficient C-peptide within 3 months of diagnosis were randomized to either MMF alone, MMF plus DZB, or placebo, and then followed for 2 years. The primary outcome was the geometric mean area under the curve (AUC) C-peptide from the 2-h mixed meal tolerance test. RESULTS One hundred and twenty-six subjects were randomized and treated during the trial. The geometric mean C-peptide AUC at 2 years was unaffected by MMF alone or MMF plus DZB versus placebo. Adverse events were more frequent in the active therapy groups relative to the control group, but not significantly. CONCLUSIONS Neither MMF alone nor MMF in combination with DZB had an effect on the loss of C-peptide in subjects with new-onset type 1 diabetes. Higher doses or more targeted immunotherapies may be needed to affect the autoimmune process

Dysglycemia and Index60 as Prediagnostic End Points for Type 1 Diabetes Prevention Trials

OBJECTIVE: We assessed dysglycemia and a T1D Diagnostic Index60 (Index60) ≥1.00 (on the basis of fasting C-peptide, 60-min glucose, and 60-min C-peptide levels) as prediagnostic end points for type 1 diabetes among Type 1 Diabetes TrialNet Pathway to Prevention Study participants. RESEARCH DESIGN AND METHODS: Two cohorts were analyzed: 1) baseline normoglycemic oral glucose tolerance tests (OGTTs) with an incident dysglycemic OGTT and 2) baseline Index60 <1.00 OGTTs with an incident Index60 ≥1.00 OGTT. Incident dysglycemic OGTTs were divided into those with (DYS/IND+) and without (DYS/IND-) concomitant Index60 ≥1.00. Incident Index60 ≥1.00 OGTTs were divided into those with (IND/DYS+) and without (IND/DYS-) concomitant dysglycemia. RESULTS: The cumulative incidence for type 1 diabetes was greater after IND/DYS- than after DYS/IND- (P < 0.01). Within the normoglycemic cohort, the cumulative incidence of type 1 diabetes was higher after DYS/IND+ than after DYS/IND- (P < 0.001), whereas within the Index60 <1.00 cohort, the cumulative incidence after IND/DYS+ and after IND/DYS- did not differ significantly. Among nonprogressors, type 1 diabetes risk at the last OGTT was greater for IND/DYS- than for DYS/IND- (P < 0.001). Hazard ratios (HRs) of DYS/IND- with age and 30- to 0-min C-peptide were positive (P < 0.001 for both), whereas HRs of type 1 diabetes with these variables were inverse (P < 0.001 for both). In contrast, HRs of IND/DYS- and type 1 diabetes with age and 30- to 0-min C-peptide were consistent (all inverse [P < 0.01 for all]). CONCLUSIONS: The findings suggest that incident dysglycemia without Index60 ≥1.00 is a suboptimal prediagnostic end point for type 1 diabetes. Measures that include both glucose and C-peptide levels, such as Index60 ≥1.00, appear better suited as prediagnostic end points

Rituximab, B-lymphocyte depletion, and preservation of beta-cell function

BACKGROUND: The immunopathogenesis of type 1 diabetes mellitus is associated with T-lymphocyte autoimmunity. However, there is growing evidence that B lymphocytes play a role in many T-lymphocyte-mediated diseases. It is possible to achieve selective depletion of B lymphocytes with rituximab, an anti-CD20 monoclonal antibody. This phase 2 study evaluated the role of B-lymphocyte depletion in patients with type 1 diabetes. METHODS: We conducted a randomized, double-blind study in which 87 patients between 8 and 40 years of age who had newly diagnosed type 1 diabetes were assigned to receive infusions of rituximab or placebo on days 1, 8, 15, and 22 of the study. The primary outcome, assessed 1 year after the first infusion, was the geometric mean area under the curve (AUC) for the serum C-peptide level during the first 2 hours of a mixed-meal tolerance test. Secondary outcomes included safety and changes in the glycated hemoglobin level and insulin dose. RESULTS: At 1 year, the mean AUC for the level of C peptide was significantly higher in the rituximab group than in the placebo group. The rituximab group also had significantly lower levels of glycated hemoglobin and required less insulin. Between 3 months and 12 months, the rate of decline in C-peptide levels in the rituximab group was significantly less than that in the placebo group. CD19+ B lymphocytes were depleted in patients in the rituximab group, but levels increased to 69% of baseline values at 12 months. More patients in the rituximab group than in the placebo group had adverse events, mostly grade 1 or grade 2, after the first infusion. The reactions appeared to be minimal with subsequent infusions. There was no increase in infections or neutropenia with rituximab. CONCLUSIONS: A four-dose course of rituximab partially preserved beta-cell function over a period of 1 year in patients with type 1 diabetes. The finding that B lymphocytes contribute to the pathogenesis of type 1 diabetes may open a new pathway for exploration in the treatment of patients with this condition

Pangolin genomes and the evolution of mammalian scales and immunity

Pangolins, unique mammals with scales over most of their body, no teeth, poor vision, and an acute olfactory system, comprise the only placental order (Pholidota) without a whole-genome map. To investigate pangolin biology and evolution, we developed genome assemblies of the Malayan (Manis javanica) and Chinese (M. pentadactyla) pangolins. Strikingly, we found that interferon epsilon (IFNE), exclusively expressed in epithelial cells and important in skin and mucosal immunity, is pseudogenized in all African and Asian pangolin species that we examined, perhaps impacting resistance to infection. We propose that scale development was an innovation that provided protection against injuries or stress and reduced pangolin vulnerability to infection. Further evidence of specialized adaptations was evident from positively selected genes involving immunity-related pathways, inflammation, energy storage and metabolism, muscular and nervous systems, and scale/hair development. Olfactory receptor gene families are significantly expanded in pangolins, reflecting their well-developed olfaction system. This study provides insights into mammalian adaptation and functional diversification, new research tools and questions, and perhaps a new natural IFNE-deficient animal model for studying mammalian immunity.University of Malaya and Ministry of Education, Malaysia [UM.C/HIR/MOHE/08]; UMRG grant from the University of Malaya and Ministry of Education, Malaysia [RG541-13HTM]; Russian Ministry of Science [11.G34.31.0068]; NIH-NHGRI grant [5U54HG00307907]SCI(E)[email protected]
