Seismic Regions

<p>The paper provides an overview of the technologies and connections proposed and tested for accelerated bridge construction (ABC) in seismic regions from New Zealand and the United States in the last seven years. These solutions can be divided in terms of emulative and non‐emulative cast‐in‐place connections. Emulative cast‐in‐place connections aim to achieve a similar seismic performance to that of conventional cast‐in‐place construction during an earthquake. A variety of emulative connections have been tested in New Zealand and in the United States, with some being implemented in actual bridges. These connections include grouted ducts, member socket, pocket, splice‐sleeve, and other connections. Similarly, various non‐emulative connection were tested using large‐scale specimens. These include dissipative controlled rocking, hybrid sliding‐rocking, shape‐memory alloys, and pre‐tensioned rocking. From these, only the dissipative controlled rocking and shape‐memory alloys, have been recently implemented in construction of actual bridges in seismic regions in New Zealand and in the United States, respectively. The paper discusses the aspects associated with emulative and non‐emulative connections.</p>

Recent Developments

This chapter looks at the use of solitary confinement in three jurisdictions where the author has conducted research: England and Wales, New Zealand, and the United States. It asks when and why prisoners are placed in solitary confinement in these jurisdictions, and what are the conditions of their confinement. The chapter's main focus is on the long-term use of solitary confinement as a tool for managing individuals classified and labeled as the most dangerous or troublesome in the prison system, including in New Zealand's Management Units and England and Wales’s Close Supervision Centres. Finally, it examines recent developments and asks what learning there might be for other jurisdictions.

<p>This paper outlines the successful development of the traditional mediation template into a community‐based model. The history of community mediation is explored within the context of the United States in the 1960s, and in Australia and New Zealand during the mid‐1980s. Recent developments in New Zealand – with particular emphasis on the promising developments occurring in Christchurch, Waitakere and Dunedin – are evaluated, though this paper acknowledges that there are limited statistics available since these schemes have only been running for a few years at most. Finally this paper takes three foundation models first postulated by Harrington and Merry, and later by Bush and Folger, and applies these models to the existing New Zealand community mediation schemes to evaluate their success.</p>

Performance Based Seismic Design

Recent research and development projects in the United States that could significantly affect the future mitigation of seismic risk are summarized. Specific activities described include a report to the governor of California on the Northridge earthquake, the ongoing effort to develop a new national seismic zoning map, development of a comprehensive regional seismic loss estimation methodology, and development of guidelines for the seismic rehabilitation of buildings. Interest in performance based seismic design is discussed and several new large-scale mitigation programs are described.

<p>Accelerated Bridge Construction (ABC) has been gaining popularity in the United States. ABC offers rapid construction, less traffic disruption, improved quality and on-site safety, better durability, and less environmental impacts. Despite these advantages, application of ABC in seismic regions is still a challenge. In this research, a new precast pier system is proposed to emulate the traditional cast- in-place seismic design (e.g. formation of plastic hinges during earthquakes). The precast elements are connected using telescoping concrete-filled steel tubes in a grouted application. Large-scale experimental testing is carried out to investigate the seismic performance of the proposed pier system and to compare it against the traditional cast-in-place construction. Experimental results showed better ductility, strength and performance of the precast piers compared to cast-in-place benchmarks. Distributed plasticity models are developed to capture the seismic performance of the proposed precast pier system. The Idaho Transportation Department is planning to implement the research in this paper in an actual bridge in Idaho.</p>

Recent Developments

Drawing on recent developments in Australian, United Kingdom and United States jurisprudence, Professor Korah casts doubt on the approach recently taken by New Zealand courts in one of the most controversial areas of competition law: the access to its facilities that a corporation in a dominant position must give to its would-be competitors.  She argues that before imposing such obligations courts ought to be more sophisticated in assessing the economic effects of such obligations and especially the need to preserve an incentive to make the considerable investment required to create such facilities.  Professor Korah was the 1999 Chapman Tripp Fellow. This article is an edited version of a paper presented at the offices of Chapman Tripp during the tenure of the Fellowship.

Abstract. During the last decades, several studies have been conducted on the effectiveness of sexual abuse prevention programs implemented in different countries. In this article, we present a review of 70 studies (1981–2017) evaluating prevention programs, conducted mostly in the United States and Canada, although with a considerable presence also in other countries, such as New Zealand and the United Kingdom. The results of these studies, in general, are very promising and encourage us to continue this type of intervention, almost unanimously confirming its effectiveness. Prevention programs encourage children and adolescents to report the abuse experienced and they may help to reduce the trauma of sexual abuse if there are victims among the participants. We also found that some evaluations have not considered the possible negative effects of this type of programs in the event that they are applied inappropriately. Finally, we present some methodological considerations as critical analysis to this type of evaluations.

End Results

Quality control of data collected in the United States by the Cancer End Results Program utilizing punchcards prepared by participating registries in accordance with a Uniform Punchcard Code is discussed. Existing arrangements decentralize responsibility for editing and related data processing to the local registries with centralization of tabulating and statistical services in the End Results Section, National Cancer Institute. The most recent deck of punchcards represented over 600,000 cancer patients; approximately 50,000 newly diagnosed cases are added annually.Mechanical editing and inspection of punchcards and field audits are the principal tools for quality control. Mechanical editing of the punchcards includes testing for blank entries and detection of in-admissable or inconsistent codes. Highly improbable codes are subjected to special scrutiny. Field audits include the drawing of a 1-10 percent random sample of punchcards submitted by a registry; the charts are .then reabstracted and recoded by a NCI staff member and differences between the punchcard and the results of independent review are noted.

This book is a new account of utopian writing. It examines how eight writers—Henry David Thoreau, W. E. B. Du Bois, Osip and Nadezhda Mandel'shtam, Anna Akhmatova, Wallace Stevens, Ezra Pound, and J. H. Prynne—construct utopias of one within and against modernity's two large-scale attempts to harmonize individual and collective interests: liberalism and communism. The book begins in the United States between the buildup to the Civil War and the end of Jim Crow; continues in the Soviet Union between Stalinism and the late Soviet period; and concludes in England and the United States between World War I and the end of the Cold War. In this way it captures how writers from disparate geopolitical contexts resist state and normative power to construct perfect worlds—for themselves alone. The book contributes to debates about literature and politics, presenting innovative arguments about aesthetic difficulty, personal autonomy, and complicity and dissent. It models a new approach to transnational and comparative scholarship, combining original research in English and Russian to illuminate more than a century and a half of literary and political history.
