SUMMARY Background and Objectives: Information on the choice of material and performance of restorations placed in a dental practice annually is limited. The Minamata Convention on Mercury is likely to affect the use of amalgam worldwide. The objective of this research was to investigate the use of restorative materials at the University of Otago Faculty of Dentistry in New Zealand from 1998 to 2017. Methods: Data from the Faculty of Dentistry's database from the years of interest were compiled. These data included information on the characteristics of restorations, including information on the material used and number of surfaces involved for each restoration. The tooth in which each restoration was placed was categorized by arch, tooth type, and deciduous or permanent dentition. Results: Records identified 227,514 permanent restorations placed from January 1998 to December 2017, of which 91.7% were direct restorations. Among direct restorations, composite resin was the most commonly used material, followed by amalgam, glass ionomer, and compomer. The use of amalgam for direct restorations decreased from 52.3% of direct restorations in 1998 to 7.1% in 2017. A corresponding increase was observed in the use of tooth-colored direct restorations, particularly composites. Among indirect restorations, porcelain fused to metal, gold, and stainless steel (in pediatric applications) were the materials most frequently used. Conclusions: Despite having no official policy on reducing the use of dental amalgam, the Faculty of Dentistry is following the global trend in reducing its use, with composite resin now well established as the predominant restorative material used. If the current rate of decline persists unchecked, the Faculty of Dentistry could transition to being amalgam free by 2020, although it seems likely that the characteristics and principles of use of the material (and its removal) will be taught for some time to come. This knowledge is important to planning curriculum changes needed to prepare graduates for clinical practice.

On the evening of March 7, 2008, the New Zealand Econometric Study Group Meeting held its Conference Dinner. The venue was the Owen Glenn Building, the spectacular new home of the Auckland Business School and the Department of Economics at the University of Auckland. The meeting was organized by my colleagues, co-authors, and close companions Donggyu Sul and Chirok Han. Chirok did double duty by videotaping the evening, Donggyu coordinated festivities with consummate skill, and we settled in to a memorable evening.Econometricians, old friends, former students, two of my former teachers, faculty, and senior administrators were gathered together to celebrate my 60th birthday. Many had traveled long distances from overseas and navigated busy schedules to come to this event. It was a singular honor. My wife and daughter were with me. Opening speeches from Bas Sharp and John McDermott broke the ice with endearing tales from the past and jokes about some mysterious hole in my vita. I stood at the front table, looked out, and felt a glow of fellowship envelop me. I was fortunate indeed. Life had bestowed many gifts. The warmth of family, friends, and collegiality were at the top of the list. My education and early training in New Zealand were a clear second.What follows is a graduate student story. It draws on the first part of the speech I gave that evening at the NZESG conference dinner. It mixes personal reflections with recollections of the extraordinary New Zealanders who shaped my thinking as a graduate student and beginning researcher—people who have had an enduring impact on my work and career as an econometrician. The story traces out these human initial conditions and unit roots that figure in my early life of teaching and research.

Community is an overarching word that encompasses people in formal and informal settings covering a broad range of activities. Engaging through sound “in community” and “as community” provides the opportunity for participants to come together making and sharing music through song. This paper focuses on voice (singing) across the Tasman within formal and informal locations. Author One draws on interview data within an “informal” space with three community choirs in regional Victoria (Australia) from her wider study Spirituality and Wellbeing: Music in the Community. The data shows that choir members use voice to connect with their local community around issues about social justice and the environment. The choir findings are reported under two overarching themes: connections to singing and wellbeing, and connections to community. Author Two uses narrative reflection as she focusses on the value of song with her generalist pre-service teacher’s in a “formal” space within the Bachelor of Education (primary) programme at the University of Auckland in New Zealand. She explores the deeper meaning, and language features such as metaphor and personification that are evident in many songs and argues that songs provide a useful context for cultural and language learning. Her narrative is discussed under two overarching themes: benefits of singing, and social and linguistic connections. Though generalisations about singing across the Tasman cannot be made to other community or educational settings, we assert that singing is a powerful medium that can foster positive growth in education and community settings.

This tribute commemorates the life and work of Guillermo (Willy) Kuschel, who made substantial contributions to the understanding of weevil systematics, evolution and biology. Willy was born in Chile in 1918 and studied philosophy, theology and biology. He became fascinated by weevils early on and completed his Ph.D. degree on South American Erirhinini. Subsequent employment by the University of Chile provided him with many opportunities to further his weevil research and undertake numerous collecting expeditions, including to remote and rugged locations such as the Juan Fernandez Islands and southern Chile. In 1963 he accepted a position at the Department of Scientific and Industrial Research in New Zealand, where he became Head of the Systematics Group in the Entomology Division. His emphasis on field work and collections led to the establishment of the New Zealand Arthropod Collection, which he guided through its greatest period of expansion. His retirement in 1983 offered him increased opportunities to pursue his weevil research. In 1988 he presented a new scheme of the higher classification of weevils, which ignited and inspired much subsequent research into weevil systematics. The breadth and quality of his research and his huge collecting efforts have left a legacy that will benefit future entomologists, especially weevil workers, for decades to come. This tribute presents a biography of Willy and accounts of his contributions to, and impact on, the systematics of weevils both regionally and globally. All of his publications and the genera and species named after him are listed in two appendices.

The Type I simple cold block device was described by Bullivant and Ames in 1966 and represented the product of the first successful effort to simplify the equipment required to do sophisticated freeze-cleave techniques. Bullivant, Weinstein and Someda described the Type II device which is a modification of the Type I device and was developed as a collaborative effort at the Massachusetts General Hospital and the University of Auckland, New Zealand. The modifications reduced specimen contamination and provided controlled specimen warming for heat-etching of fracture faces. We have now tested the Mass. General Hospital version of the Type II device (called the “Type II-MGH device”) on a wide variety of biological specimens and have established temperature and pressure curves for routine heat-etching with the device.

There is a difference between doing something well and doing something good. And there is a difference between failing to do something well, and failing to do something good. In this paper, I assess our contemporary University in the latter sense of failure. While the University can be ineffective, or fail to function well, there is more at stake if the University, as an institution, is in conflict with nature. That is, it is one thing for the University to be ineffective in its means, but here I will pose the question: is the contemporary University sinful? Using Josef Pieper's elucidation of moral failure and John Henry Newman's analysis of the proper ends of University education, I defend the thesis that because the aim of our contemporary University seems to come in conflict with the goal of nature as a whole, it may be understood as sinful.

Abstract While the Antarctic Treaty System intended to keep Antarctica an area of international cooperation and science free from militarisation and international conflict, the region has not been completely shielded from global power transitions, such as decolonisation and the end of the Cold War. Presently, emerging countries from Asia are increasingly willing to invest in polar infrastructure and science on the back of their growing influence in world politics. South Korea has also invested heavily in its Antarctic infrastructure and capabilities recently and has been identified as an actor with economic and political interests that are potentially challenging for the existing Antarctic order. This article first assesses the extent and performance of the growing bilateral cooperation between South Korea and one of its closest partners, New Zealand, a country with strong vested interests in the status quo order. How did the cooperation develop between these two actors with ostensibly diverging interests? This article finds that what may have been a friction–laden relationship, actually developed into a win-win partnership for both countries. The article then moves on to offer an explanation for how this productive relationship was made possible by utilising a mutual socialisation approach that explores socio-structural processes around status accommodation.

Imagine the University where everything runs smoothly, there is no need to worry about information that needs to be known where the University shares all information in your ear. Imagine that you know every location of your University and the schedules are relevant. This research focuses on the problem faced by Kathmandu University (KU) students while searching for their lecture room and managing their class schedule. This research is carried out for proposing knowledge portal for an intelligent class scheduling and location directing on the central campus of KU. The quest of the information world to make everyday easier has driven us to come up with the concept of such an app and this research consists of role of knowledge management for the development of an application by sharing and exchange of information between individuals and the administration. The university will be benefited in at least a small way through the paper.

In the last decade, there has been a surge in the number of academic research groups and commercial companies exploiting naturally occurring cosmic-ray muons for imaging purposes in a range of industrial and geological applications. Since 2009, researchers at the University of Glasgow and the UK National Nuclear Laboratory (NNL) have pioneered this technique for the characterization of shielded nuclear waste containers with significant investment from the UK Nuclear Decommissioning Authority and Sellafield Ltd. Lynkeos Technology Ltd. was formed in 2016 to commercialize the Muon Imaging System (MIS) technology that resulted from this industry-funded academic research. The design, construction and performance of the Lynkeos MIS is presented along with first experimental and commercial results. The high-resolution images include the identification of small fragments of uranium within a surrogate 500-litre intermediate level waste container and metal inclusions within thermally treated GeoMelt® R&D Product Samples. The latter of these are from Lynkeos' first commercial contract with the UK National Nuclear Laboratory. The Lynkeos MIS will be deployed at the NNL Central Laboratory facility on the Sellafield site in Summer 2018 where it will embark upon a series of industry trials.

Government Reforms

In this study the authors analyze the effects of e-government reforms that began in mid-90ies by confronting the promises which these reforms made to government performance in the period before and after the reforms took place. The authors use fiscal and performance indicators of the Slovenian government and courts to argue that e-government did not yield any notable effects on the state performance. Finally, the authors analyze the reasons why e-government technology cannot be regarded as sustainable and suggest a different approach towards researching how to sustainably improve governance for generations to come.
