title: Establishing professional relationships in practicum settings

authors: Ferrier-Kerr, Jenny L.

subjects: associate teacher

abstract: The relationship between an associate teacher and student teacher is a crucial aspect of the practicum experience in pre-service teacher education.
Establishing a professional relationship is critical to the learning that occurs during the practicum and is an element that requires a professional approach by all parties. This paper discusses a study which investigated the nature and substance of the professional relationship established between associate teachers and student teachers during a final block practicum. The findings indicated that for the associate teacher and student teacher to establish and develop a successful professional relationship both must be active in it.

title: Cascomp BJT Amplifier vs. traditional configurations

authors: Jull, Harrisson

subjects: Cascomp

abstract: All transistor circuits introduce distortion. In Radio Frequency (RF) circuits, the third-order distortion components are the most important. The quest for more linear circuits has become more important with complex-modulation as used in modern cellular phone systems. Quinn’s Cascomp Amplifier, first reported in the 1970s, promises ideal linearity and can deliver close to that promise. We review the theory and address the question of why the Cascomp has not replaced other configurations in amplifiers where low distortion is important. Calculations are supported by measurements. A new, alternative variant of the Cascomp topology is introduced and compared with the existing configura-tion. We assert that the improved linearity comes at such a price in gain that it does not make sense to use the configuration in broadband RF circuits.

title: Joseph Harris Smallman

authors: Hart, Philip

abstract: Born to a mining agent and trained as a mining surveyor, in 1864, less than a year after the birth of his first child, Smallman left England for New Zealand to establish a ‘Mining business’, promising that his family would join him once it was successful. But they were never asked to join him, and after 1870 he ceased to write to his wife. 
The ‘Mining business’ never eventuated, but in 1865 he prospected at Thames, unsuccessfully seeking alluvial gold. Although criticized for living off Maori and doing little prospecting, with his partner he investigated several areas of the Hauraki Peninsula, again unsuccessfully. When the Thames goldfield was opened, with his encouragement, two years later, he mined there for some years, proving himself to be a competent miner but not making his fortune. After working elsewhere, by the mid-1870s he was living with another man’s ‘half-caste’ wife on her land near Te Aroha, having five children with her. Happy to be described as a Pakeha Maori and closely associated with the local hapu, he supported them over land dealings and the development of the district. Despite spending most of his time farming, he remained interested in prospecting, and made some explorations in districts closed to Pakeha. After gold was found at Te Aroha, for a short time he worked with Maori partners in unprofitable claims.
Either before or after his second wife had a child by another man in 1886, he left New Zealand to return to his English family; and remarkably, despite his first wife knowing that his liaison had produced children, she accepted him back after his long absence, and they remained together for the rest of their lives.
