title: Interunion conflict in a non-exclusive, non-majority representation regime: New Zealand lessons for union revival in the United States

authors: Harcourt, Mark

subjects: employee representation

abstract: A “new” interpretation of Section 7 in the National Labor Relations Act could serve as the basis of union renewal, in enabling and supporting non-majority, non-exclusive representation as an alternative to the difficulties of union certification. One potential shortcoming of this form of representation is interunion conflict associated with ongoing competition between unions trying to attract each other's members in the same bargaining units. However, interview evidence collected from union executives in New Zealand, where non-majority, non-exclusive representation already exists, suggests that such conflict is normally limited. Focusing representation on areas that make the most sense (for both unions and workers) and following union federation protocols, when conflicts occur, have both contributed to the overall low conflict level. Lessons for US unionism are explored.

title: The effect of heat treatments on microstructure and mechanical properties of as-extruded Ti-6Al-4V alloy rod from blended elemental powders

authors: Romero Villarreal, Carlos

abstract: In this study, Ti-6Al-4V bars were first prepared by extrusion of powder compacts from blended powder mixtures in the beta phase region, then the as-extruded bars were heat-treated following four different conditions: beta quenching and aging (βQA), broken up structure (BUS) treatment, solution treatment and aging (STA) and recrystallization annealing (RA). The effect of the heat treatments on microstructure and mechanical properties was studied using optical microscopy, scanning electron microscopy, and mechanical test to determine which heat treatment condition has the greatest impact on the mechanical properties of the as-extruded Ti-6Al-4V alloy. The results show that the as-extruded condition has the best balance of strength (1120 MPa of UTS) and ductility (11% of elongation to failure). βQA and STA lead to a slight increase in strength but ductility decreases considerably. After BUS and RA treatments, both strength and ductility are reduced. The relationship between processing, microstructure and properties was studied, and their implications towards fatigue behaviour and fracture toughness discussed.

title: An Interactive User Management System for Multilingual Documents: A case study of the Pei Jones collection

authors: Cader, Papitha

subjects: Greenstone Digital Library

abstract: Can general purpose DL software architecture be designed to provide a flexible environment that supports both the management and end-user roles through a single unified web interface? In particular we take the collected correspondence of the Māori scholar Dr. Pei Jones and undertake case study of how this approach can be applied in a practical way.
