The effects of positive student-teacher relationships on students\u27 perceptions of school safety

Previous research has resulted in positive information regarding the student-teacher relationship and perceptions of student safety, from the perspective of adults. A number of studies have investigated relationship building and student safety, teacher characteristics, school connectedness, and perceptions of safety. However, previous studies have not included the stories and perceptions from students themselves. This study aims to use interviews conducted with middle school students to inform the perspective of middle school students on their student-teacher relationships and perceptions of school safety. Each participant was asked questions related to their feelings of safety at school, current relationships with teachers, their ideal student-teacher relationship, and how relationships with teachers impact their perception of safety. Data from the individual interviews were analyzed using narrative analysis to give meaning to the participants’ stories. Analysis of results examines common themes among participant responses in regard to their feelings of school safety as it relates to their relationships with teachers. Suggestions for future research and implications for school psychologists are included

Recent palaeoenvironmental evidence for the processing of hemp (Cannabis sativa L.) in eastern England during the medieval period

[FIRST PARAGRAPH] Hemp (Cannabissativa L.)— whose origins as a domesticated plant probably lie in C.Asia — has been cultivated in England since at least a.d.800 (and before this perhaps in the Roman Period), mainly for its ¿bre, which was used to make sails, ropes, ¿shing nets and clothes, as well as for the oil from hempseed. Hemp cultivation may have reached a peak during the early 16th century, when Henry VIII decreed that increased hemp production was required to supply the expanding navy. Evidence for the locations where the crop was cultivated and processed is available in several different forms, including written evidence in parish records and government reports, place-name evidence (e.g.Hempholme and some instances of Hempstead), and features on old maps, such as Hempis¿eld (hemp¿eld)

Transforming growth factor beta (TGF beta) mediates schwann cell death in vitro and in vivo: Examination of c-jun activation, interactions with survival signals, and the relationship of TGF beta-mediated death to schwann cell differentiation

In some situations, cell death in the nervous system is controlled by an interplay between survival factors and negative survival signals that actively induce apoptosis. The present work indicates that the survival of Schwann cells is regulated by such a dual mechanism involving the negative survival signal transforming growth factor beta (TGF beta), a family of growth factors that is present in the Schwann cells themselves. We analyze the interactions between this putative autocrine death signal and previously defined paracrine and autocrine survival signals and show that expression of a dominant negative c-Jun inhibits TGF beta -induced apoptosis. This and other findings pinpoint activation of c-Jun as a key downstream event in TGF beta -induced Schwann cell death. The ability of TGF beta to kill Schwann cells, like normal Schwann cell death in vivo, is under a strong developmental regulation, and we show that the decreasing ability of TGF beta to kill older cells is attributable to a decreasing ability of TGF beta to phosphorylate c-Jun in more differentiated cells
