Analysing Scientific Collaborations of New Zealand Institutions using Scopus Bibliometric Data
Scientific collaborations are among the main enablers of development in small
national science systems. Although analysing scientific collaborations is a
well-established subject in scientometrics, evaluations of scientific
collaborations within a country remain speculative with studies based on a
limited number of fields or using data too inadequate to be representative of
collaborations at a national level. This study represents a unique view on the
collaborative aspect of scientific activities in New Zealand. We perform a
quantitative study based on all Scopus publications in all subjects for more
than 1500 New Zealand institutions over a period of 6 years to generate an
extensive mapping of scientific collaboration at a national level. The
comparative results reveal the level of collaboration between New Zealand
institutions and business enterprises, government institutions, higher
education providers, and private not for profit organisations in 2010-2015.
Constructing a collaboration network of institutions, we observe a power-law
distribution indicating that a small number of New Zealand institutions account
for a large proportion of national collaborations. Network centrality concepts
are deployed to identify the most central institutions of the country in terms
of collaboration. We also provide comparative results on 15 universities and
Crown research institutes based on 27 subject classifications.Comment: 10 pages, 15 figures, accepted author copy with link to research

Desert Island Discs and British emotional life
This chapter explores how the long-running BBC radio programme Desert Island Discs has responded over time to an increasing public appetite for openness and honesty. One of the programme’s presenters once said it was ‘properly impressed by power, wealth and ambition, but… knows that the world is made up of more than that’. This spoke to a longer-term revolution in modern life, as outlined by historians of the emotions: an increasing informality of manners, especially in broadcast talk. How did the BBC navigate these trends in a series that had long been a by-word for decorum? And what did Radio 4 listeners think of its new willingness in the 1980s and 1990s to probe guests more deeply? Drawing on unpublished BBC records and Mass Observation archives, this chapter focuses on how various desires for openness over private lives and feelings - and the anxieties this prompted - were negotiated behind-the-scenes at crucial moments in its history
Historical and contemporary perspectives on the sediments of Lake Rotorua
Lake Rotorua is probably the oldest continuously inundated lake in New Zealand, occupying a caldera formed by or closely associated with the eruption of the Mamaku ignimbrite and the collapse of the Rotorua caldera (Healy, 1975; Lowe and Green, 1991). The lake has undergone drastic changes in size and depth as a result of tectonics, volcanic activity and erosion. Since the Rotoehu eruption, (~60 kyr), the lake level has fluctuated between 120 m above present (280 m asl) and 10 m below present level. The modern lake covers an area of 79 km2 and has a mean depth of 10 m. Despite its long history of sedimentation, Lake Rotorua has an irregular bathymetry with features including faulted blocks, slumps, hydrothermal explosion craters, springs and large methane discharge pock marks

Drought contingency planning for pastoral livelihoods
This publication highlights issues arising from approaches to the mitigation of the impact of drought on pastoral households in Africa. It draws heavily upon drought management experience in Kenya and describes those policies most likely to have a positive impact on pastoral household livelihoods
University of Waikato radiocarbon dates I
This date list reports on samples submitted by University of Waikato researchers and assayed in the Waikato laboratory mainly between 1979 and 1985. Most dates reported here relate to the deposition of distal airfall tephras in lakes and peats in central and northern North Island, New Zealand. Most of the tephras have been correlated with named eruptive units elsewhere using diagnostic mineralogic and chemical criteria, together with stratigraphic and age relationships.The dates listed in Section 2 were obtained on carbonaceous matter associated with the Hinuera Formation, an extensive low-angle fan of volcanogenic alluvium that was deposited in several phases in the Waikato and Hauraki basins before and during the last stale (isotope stage 2) of the last glaciation. In Section 3, the samples comprise materials associated with peat bog growth or local sedimentation that postdates the deposition of the Hinuera Formation, ie, < ca 15,000 BP. Samples in both Sections 2 and 3 are grouped into series according to geographic location, and, where appropriate, arranged stratigraphically with uppermost samples shown first
Interview with David Hendy : Writing an Official History of the BBC in 2020
David Hendy is Professor of Media and Cultural History at the University of Sussex. He is the author of Noise: a Human History of Sound and Listening, which was also a BBC Radio 4 documentary series. He is currently working on a new, authorized history of the BBC, which will be published for the BBC's Centenary in 2022. He is also the Principal Investigator on a five-year project, Connected Histories of the BBC, which involves bringing the BBC's own oral history archive into the public realm ..
Absence of visitors during lockdown reveals natural variation in carbon dioxide level in the Glowworm Cave, Waitomo, New Zealand
Waitomo Glowworm Cave is a highly visited cave where the highlight is viewing the bioluminescence display of a large colony of glowworms. Anthropogenic carbon dioxide build-up in the cave is prevented by management of chimney-effect ventilation aided by a network of microclimate sensors. A cave door prevents ventilationunder drying conditions and promotes it when necessary to clear CO2 and when inflowing air has high relative humidity. A COVID-19-related nationwide “lockdown” in New Zealand from March 2020 resulted in neither staff nor visitors being present in the cave for 60 days, and provided an opportunity to assess the natural microclimate of the cave, especially the natural variation in partial pressure of carbon dioxide (pCO2). In addition, comparison to the previous year showed that the presence of people in the cave increased the cave temperatures but the effect was short-lived due to cave ventilation. During the period of lockdown, the daily increase of carbon dioxide partial pressure (pCO2) due to visitors was absent. When the cave door remained sealed, pCO2 varied and tended to lie at levels above that of the external atmosphere (410 ppm). Notably, rain events raised pCO2 by up to 200 ppm (v/v), which appeared to be sourced from both stream water and drip water. These natural CO2 sources rarely reached the levels associated with cave visitation. The results support current management practices that use door control to enhance cave ventilation when people are in the cave or when natural conditions (high stream levels and high drip-water levels) promote CO2 outgassing into the cave. Suppressing ventilation outside of those times reduces the risk of introducing dry air that could desiccate the glowworms
Superheating and solid-liquid phase coexistence in nanoparticles with non-melting surfaces
We present a phenomenological model of melting in nanoparticles with facets
that are only partially wet by their liquid phase. We show that in this model,
as the solid nanoparticle seeks to avoid coexistence with the liquid, the
microcanonical melting temperature can exceed the bulk melting point, and that
the onset of coexistence is a first-order transition. We show that these
results are consistent with molecular dynamics simulations of aluminum
nanoparticles which remain solid above the bulk melting temperature.Comment: 8 pages, 5 figure
