Directional coupler for optical waveguides

Feasibility study of transmitting optical energy in single mode through photonic waveguides results in a conceptual directional coupler consisting of two types of optical waveguides /a stratified /core/ dielectric and a mirror wall/. Waveguide medium analysis produced formulation of mode cutoff conditions, field distributions, and propagation characteristics

Entrenching heterosexuality through language in South African Life Orientation (LO) textbooks

Studies of the representation of sexualities in textbooks have tended to focus on inclusion and coverage of diverse content through thematic analysis. This analysis of a sample of LO textbooks is framed by the systematic linguistic framework of critical discourse analysis (CDA), specifically Fairclough’s (2001) theory of discourse as ideological meanings encoded in text. The sections on sex education in three popularly used LO textbooks have been analysed to make explicit the heteronormative meanings conveyed through language used. This article provides insight into how the language in the LO texts function to legitimate the dominant discourse of a particular type of heterosexuality: monogamy for the primary purpose of reproduction. The implications of this bias are raised and recommendations for fair representation of LGBT sexual orientations are made

Issues and challenges facing school libraries in selected primary schools in Gauteng Province, South Africa

There is no national policy for school libraries which compels school governing bodies and principals to have a library in their schools. It is thus not surprising that in 2011, only 21% of state schools had libraries, only 7% had stocked libraries and 79% of schools had no library at all (Department of Basic Education (DBE) Republic of South Africa, 2011a:23). This article forms part of a broader qualitative study which investigated 10 primary schools in Gauteng Province, South Africa that had libraries, or were in the process of setting up a library, with the intention of providing a rich description of the issues and challenges facing these schools. The 10 schools used in this study were chosen on the basis of their location and fee structures. They represented the full continuum of fees within the state structure. In this article, we discuss three core categories of predicaments faced by primary school libraries. These were resourcing the library, operating the library and the role of the library. Our main contention is that school libraries are not playing an effective role in supporting and enabling quality education for all South African children. This needs to be addressed by government as a matter of urgency.Keywords: academic achievement; books; information and communication technologies; information literacy; literacy; national school library policy; quality education; reading; school librarians; school librarie

Northeast Folklore volume 4: Eight Folktales From Miramichi

Volume 4 of Northeast Archives marked a change in the publication. No longer was it published in four editions throughout the year with a variety of small articles, but now it was a single monograph published generally once a year. The focus of the first monograph is Wilmot MacDonald, a singer and storyteller from Miramichi, New Brunswick. Helen Creighton and Edward D. Ives had both collected from MacDonald and this publication came from their collaboration on that material. Eight Folktales from Miramichi: as Told by Wilmot MacDonald Table of Contents: Wilmot MacDonald by Louise Manny Introduction 1) The Bull Story 2) The Christmas Story 3) Jack and the Beanstalk 4) Three Gold Hairs from the Giant’s Back 5) The Sword of Brightness 6) Out-Riddling the Judge 7) John the Cobbler 8) The Haunted House and the Headless Ghosthttps://digitalcommons.library.umaine.edu/nf/1000/thumbnail.jp

Critical incidents in a forensic psychiatric population: An exploratory study of motivational factors

This exploratory study examined the motivations for forensic clients’ engagement in critical incidents, specifically hostage-taking, barricades and roof-top protests. Using thematic analysis, a range of themes were identified. These included engaging in such incidents to seek deliberate isolation from others, gaining control, getting their needs meet, a need to communicate and being influenced by their peers. Selection of potential hostages appeared linked to feeling of grievance towards them. Yet the distress of a hostage, along with consideration as to the longer term consequences of their actions both for themselves and morally, appeared to reduce the risk of engagement in such incidents. The results are discussed in terms of Individualism, Self-Determination Theory of Motivation and Maslow’s Hierarchy of Human Needs
