Few studies have examined the effectiveness of gay–straight alliances (GSAs) on the social and academic experiences of lesbian, gay, bisexual, transgender, and questioning (LGBTQ) youths. The limited research on GSAs suggests that they are associated with positive youth development and increased safety; however, little qualitative information exists on the issues of why GSA groups are effecti…

Middle school presents challenges to the gender identity of girls as they struggle to define who they are in an environment that is larger and more impersonal than their elementary school. For girls of color, this transition also involves an exploration of their identities as female members of racially and ethnically devalued groups. Authors of this research study conducted four focus groups w…

A number of case studies and legal briefs describe very troubling incidents faced by secondary school students because of their minority religious group affiliation. The purpose of the study described in this article was to understand the lived experiences of minority religious youths who attend public schools in an area of the United States where the majority of students are affiliated with on…

Students’ perceptions of school danger have been associated with several negative academic, behavioral, and developmental outcomes. However, little research has focused on which contextual factors influence rural youths’ perceptions of school danger. Through hierarchical regression analyses, the study presented in this article explored the relative importance of parent, peer, school experie…

Let Γ be a connected G-vertex-transitive graph, let v be a vertex of Γ and let GΓ(v) v be the permutation group induced by the action of the vertex-stabilizer Gv on the neighbourhood Γ(v). The graph Γ is said to be G-locally primitive if GΓ(v) v is primitive. Weiss conjectured in 1978 that there exists a function f : N → N such that, if Γ is a connected …

For s >= 4, the 3-uniform tight cycle C3 s has vertex set corresponding to s distinct points on a circle and edge set given by the s cyclic intervals of three consecutive points. For fixed s >= 4 and s ≡ 0 (mod 3), we prove that there are positive constants a and b with 2at < r(C3 s,K3 t ) < 2bt2 log t. The lower bound is obtained via a probabilistic construction. The upper bound for s …

We formulate a conjecture about the distribution of the canonical height of the lowest non-torsion rational point on a quadratic twist of a given elliptic curve, as the twist varies. This conjecture seems to be very deep and we can prove only partial results in this direction.
