The evolution of equation-solving: Linear, quadratic, and cubic

This paper is intended as a professional developmental tool to help secondary algebra teachers understand the concepts underlying the algorithms we use, how these algorithms developed, and why they work. It uses a historical perspective to highlight many of the concepts underlying modern equation solving

Strategies and beliefs about conflict resolution: comparing children with language-learning disorders to children with typical language development

The purpose of the current study was to compare the conflict resolution skills and beliefs of children with Language and Learning Disorders (LLD) to those with typically developing language (TDL). All of the participants were drawn from a rural middle school in southeastern Louisiana. The independent variable was linguistic ability and it included two groups of children, thirteen with LLD and a comparison group of eight controls with TDL. The children’s conflict resolution skills and beliefs were collected by giving the children a hypothetical scenario of conflict and then asking them about resolution through an interview format. Conflict resolution measures from these interviews were: the number of strategies the children produced to resolve conflict, the complexity level of the strategies the children produced, and the cognitive level of the children’s beliefs about conflict. Differences were not found in the number of strategies produced by children with LLD and the controls. However, the children with LLD produced a lower level of strategy to resolve conflict and a lower level of cognitive belief about conflict than did the controls, with the latter resulting in a statistically significant group difference

The Leadership of Women: A Conversation Among Presidents of Mount Saint Vincent University

Atlantis is pleased to celebrate the 125th anniversary of Mount Saint Vincent by including an edited conversation among past and current Presidents of the Mount. Sister Mary Albertus Haggerty was president from 1974 - 1978; E. Margaret Fulton, from 1978 - 1986; Naomi Hersom, from 1987 - 1991; Elizabeth Parr-Johnston, from 1991 - 1996; and Sheila Brown, 1996 to the present. The original conversation was held in the Fall of 1998, and was chaired by Wayne Ingalls, who had worked with each of the Presidents during her tenure. Elizabeth Parr-Johnston was not able to be present at the original conversation, and was taped separately in conversation with Sheila Brown.Atlantis est Her de celebrer le 125eme anniversaire du Mount Saint Vincent en incluant une conversation revisee entre les anciennes presidentes et la presidente actuelle du Mount.

PERK/EIF2AK3 integrates endoplasmic reticulum stress-induced apoptosis, oxidative stress and autophagy responses in immortalised retinal pigment epithelial cells

Retinal pigment epithelium (RPE) performs essential functions for ensuring retinal homeostasis and is a key site for pathogenic changes leading to age-related macular degeneration (AMD). Compromised proteostasis in RPE results in ER stress and ER stress-dependent antioxidant, apoptosis and autophagic responses. ER stress induces the unfolded protein response (UPR) in which EIF2AK3, encoding the protein kinase RNA-like ER kinase (PERK), acts as a key regulator. Downregulated EIF2AK3 gene expression has recently been identified in AMD using human donor RPE, however the molecular mechanisms that integrate the various ER-mediated cellular pathways underpinning progressive RPE dysfunction in AMD have not been fully characterised. This study investigated the downstream effects of PERK downregulation in response to Brefeldin A (BFA)-induced ER stress in ARPE-19 cells. PERK downregulation resulted in increased ER stress and impaired apoptosis induction, antioxidant responses and autophagic flux. ARPE-19 cells were unable to efficiently induce autophagy following PERK downregulation and PERK presented a role in regulating the rate of autophagy induction. The findings support PERK downregulation as an integrative event facilitating dysregulation of RPE processes critical to cell survival known to contribute to AMD development and highlight PERK as a potential future therapeutic target for AMD
