Using Self-Disclosure to Manage Student Misconceptions in a Human Sexuality Classroom

This paper explores how three Human Development graduate student instructors of human sexuality have utilized student perception and instructor disclosure to challenge assumptions and misconceptions about sexuality. Three modes of pedagogy, culturally responsive pedagogy, experiential learning theory, and queer pedagogy, are discussed in order to illustrate the interplay of perception and disclosure when teaching. The authors provide a list of questions for instructors to be reflective as well as strategies to respond to student misconceptions about sexuality topics in the classroom.Keywords: culturally responsive pedagogy, disclosure, experiential learning theory, queer pedagogy, sexualit

SARS-CoV-2 Breakthrough Infections: Incidence and Risk Factors in a Large European Multicentric Cohort of Health Workers.

Background: The research aimed to investigate the incidence of SARS-CoV-2 breakthrough infections and their determinants in a large European cohort of more than 60,000 health workers. Methods: A multicentric retrospective cohort study, involving 12 European centers, was carried out within the ORCHESTRA project, collecting data up to 18 November 2021 on fully vaccinated health workers. The cumulative incidence of SARS-CoV-2 breakthrough infections was investigated with its association with occupational and social-demographic characteristics (age, sex, job title, previous SARS-CoV-2 infection, antibody titer levels, and time from the vaccination course completion). Results: Among 64,172 health workers from 12 European health centers, 797 breakthrough infections were observed (cumulative incidence of 1.2%). The primary analysis using individual data on 8 out of 12 centers showed that age and previous infection significantly modified breakthrough infection rates. In the meta-analysis of aggregated data from all centers, previous SARS-CoV-2 infection and the standardized antibody titer were inversely related to the risk of breakthrough infection (p = 0.008 and p = 0.007, respectively). Conclusion: The inverse correlation of antibody titer with the risk of breakthrough infection supports the evidence that vaccination plays a primary role in infection prevention, especially in health workers. Cellular immunity, previous clinical conditions, and vaccination timing should be further investigated

REGULAR EMBEDDINGS OF K-N,K-N WHERE N IS A POWER OF 2. I: METACYCLIC CASE

A 2-cell embedding of a graph in an orientable closed surface is called regular if its automorphism group acts regularly on arcs of the embedded graph. The aim of this and of the associated consecutive paper is to give a classification of regular embeddings of complete bipartite graphs K-n.n, where n = 2(e). The method involves groups G which factorize as a product XY of two cyclic groups of order n so that the two cyclic factors are transposed by an involutory automorphism. In particular, we give a classification of such groups G. Employing the classification we investigate automorphisms of these groups, resulting in a classification of regular embeddings of K-n.n, based on that for G. We prove that given n = 2(e) (for e >= 3), there are, up to map isomorphism, exactly 2(e-2) + 4 regular embeddings of K-n.n. Our analysis splits naturally into two cases depending on whether the group G is metacyclic or not. (C) 2006 Elsevier Ltd. All rights reserved.X1124sciescopu

Regular embeddings of Kn,n where n is a power of 2. II: The non-metacyclic case

The aim of this paper is to complete a classification of regular orientable embeddings of complete bipartite graphs K(n,n), where n = 2(e). The method involves groups G which factorise as a product G = XY of two cyclic groups of order n such that the two cyclic factors are transposed by an involutory automorphism. In particular, we give a classification of such groups G in the case where G is not metacyclic. We prove that for each n = 2(e), e >= 3, there are up to map isomorphism exactly four regular embeddings of K(n,n), such that the automorphism group G preserving the surface orientation and the bi-partition of vertices is a non-metacyclic group, and that there is one such embedding when n = 4.
