Abstract

Professor William (Bill) Budd was a founding figure in Australian glaciology, and the first glaciology program leader of the Australian Antarctic Division (Fig. 1). Bill worked on an enormous range of glaciological and meteorological problems covering numerical modelling of ice sheets and glaciers, including surging glaciers; ice mechanics; ice crystallography; ice core paleoclimatic studies; relationships between sea ice and climate; and katabatic wind and snow drift studies. Bill introduced and led studies of ice sheet mass budget, ice rheology, ice sheet thermodynamics, iceberg distribution and movement, drifting snow, sea ice and climate interactions and much more. He initiated Australian ice core drilling (initially for study of ice dynamics and later for palaeoclimate research), radio echo sounding of ice thickness and satellite remote sensing of ice. Much of what Bill Budd initiated more than fifty years ago remains core to the present-day Australian Antarctic glaciological research program. Professor William (Bill) Budd, the first glaciology program leader of the Australian Antarctic Division, was a founding figure in Australian glaciological research. Bill worked on an enormous range of glaciological and climate problems. He developed numerical models to simulate the interactive response of Antarctica to global warming and the waxing and waning of ice ages.

Abstract

We use lattice QCD to predict the mass of the $B_c$ meson. We use the MILC Collaboration's ensembles of lattice gauge fields, which have a quark sea with two flavors much lighter than a third. Our final result is $m_{B_c}=6304\pm12^{+18}_{- 0} MeV$. The first error bar is a sum in quadrature of statistical and systematic uncertainties, and the second is an estimate of heavy-quark discretization effects., Comment: 4 pages, 3 figures; shorten to fit in PRL; published version

Abstract

This thesis differs from the technological perspective of SPI by identifying and analysing the organisational features of process improvement. A theoretical understanding is developed of how and why software process improvements occur and what are the consequences of the change process within a specific case. A packaged information systems organisation forms the basis for a substantive case study. Adding to the growing body of qualitative research, the study takes a critical hermeneutic perspective. In doing so it overcomes some of the criticisms of the interpretive studies especially the need for the research to be reflexive in nature. By looking at SPI as an emergent rather than deterministic activity, the design and action of the change process are shown to be intertwined and shaped by their context. This understanding is based upon a structurational perspective that highlights how the process improvements are enabled and constrained by their context. The work builds on the recent recognition that the improvements can be understood from an organisational learning perspective. Fresh insights to the improvement process are developed by recognising the role of the individual to facilitate or resist the improvement. The understanding gained here can be applied by organisations to enable them to improve the effectiveness of their SPI programmes, and so improve the quality of their software. Lessons are derived that show how software organisations can support the ongoing improvement through recognition of the learning and political aspects of the change by adopting an agile approach to SPI.

Abstract

Using data from three automatic weather stations (LGB69, Eagle and Dome A) from distinctly different climatological zones along the CHINARE (Chinese National Antarctic Research Expedition) traverse route from Zhongshan Station to Dome A, we investigated the characteristics of meteorological conditions and subsurface heat conduction. Spatial analysis indicated decreasing trends in air temperature, relative humidity and wind speed from the coastal katabatic wind zone to the inland plateau region, and air temperatures clearly showed a strong daily variability in winter, suggesting the effect from the fluctuation in the Antarctic atmospheric system. We also analyzed the optimal response time of the 1 and 3 m depth snow temperatures to the 0.1 m depth snow temperature for each site under clear/overcast and day/night situations. This showed an important enhancement to the heat transfer from shortwave radiation penetration. Using an iterative optimization method, we estimated the subsurface heat conduction variations along the transect. This was ~3–5 W m–2. Multiple maxima in daily mean subsurface fluxes were found in winter, with a typical value above 2 W m–2, while a single minimum value under –2 W m–2 was found in summer. On an annual scale, a larger mean loss of subsurface heat conduction was observed in the inland plateau compared to in the coastal katabatic area. Finally, we discussed the possible influences of turbulent and radiant transport on the vertical heat response and confirmed the wind enhancement on the growth of thermal conductivity. This preliminary study provides a brief perspective and an important reference for studying subsurface heat conduction in inland areas of Antarctica. [ABSTRACT FROM AUTHOR]

25. Roles of Middle Managers in Agile Project Governance

Author

Uwadi, Peggy, Gregory, Peggy, Allison, Ian, Sharp, Helen, Uwadi, Peggy, Gregory, Peggy, Allison, Ian, and Sharp, Helen

Abstract

Project governance is an important activity in agile software development (ASD) projects for project success. Middle managers are part of the governance structure in ASD projects. Despite the efficacy of project governance and existence of middle managers in agile teams, project governance and middle management in ASD projects are under-researched. This multiple-case study investigates the roles of middle managers in agile project governance activities within two Nigerian ASD projects through the lens of activity theory. We collected data in semi-structured interviews, observations, questionnaires, and company documents. Our findings show that middle managers performed 25 roles related to planning and coordination for project alignment and execution, continuous improvement and organisational change, agile and technical leadership, monitoring, and capability building. We conclude that middle managers are pivotal to project governance practice and the effectual functioning of agile teams in ASD projects. The study will help agile practitioners to better understand the roles of middle managers in agile project governance. Results from this work contribute to the ‘middle management in agile’ debate and offer an alternative view that may change beliefs about middle managers in agile project settings.

37. Ice sheets, glaciers, and sea level

Abstract

Within the past 125,000 years, variations in Earth’s climate have resulted in global sea levels fluctuating from 130 to 140 m lower than present day to 6 to 9 m higher. Presently, global mean sea level is rising at its fastest rate in the past 6000 years (at ~ 3.6 mm/year for 2006–2015) and is accelerating. In this chapter, we discuss both the causes and implications of sea-level rise from the perspective of a cryospheric hazard. We also review the best estimates of sea-level rise and cryospheric mass change from a variety of monitoring techniques. The transfer of ice into the sea has contributed almost 50% of the sea-level rise since 1993 and exceeded the combined sea-level changes due to thermal expansion, changes in terrestrial water storage, and changes in ocean basin size since at least 2006. This cryospheric contribution to sea-level rise is split between the combined ice sheets of Greenland and Antarctica and the global population of about 215,000 glaciers. Over the last decade, the contribution from ice sheets has been increasing faster than that from glaciers. The societal effects of sea-level rise will be highly varied throughout the world, with some locations experiencing a sea-level fall, while others experience a sea-level rise several times the global mean. Perhaps counterintuitively, the sea-level rise due to terrestrial ice loss will be most substantial in areas furthest from the source of melting ice. Although this cryospheric hazard will unfold over a much longer timescale than many of the other hazards discussed in this volume, the ramifications of sea-level rise will likely be more widespread and profound. Some of the most important implications discussed here include coastal inundation, increased coastal flood frequency, and groundwater salination.

Abstract

This paper introduces a unique multiyear dataset and the monitoring capability of the PANDA automatic weather station network which includes eleven automatic weather stations (AWS) across Prydz Bay-Amery Ice Shelf-dome area from the coast to the summit of the East Antarctica ice sheet. The ~1460 km transect from Zhongshan to Panda S station follows roughly along ~77° E longitude and covers all geographic and climatic units of East Antarctica. Initial inland observation, near the coast, started in the 1996/1997 austral summer. All AWSs in this network measure air temperature, relative humidity, air pressure, wind speed and wind direction at 1-hour intervals, and some of them can also measure firn temperature and shortwave/longwave radiation. Data are relayed in near real-time via the ARGOS system. Data quality is generally very reliable and the data have been used widely. In this paper, we firstly present a detailed overview of the AWSs, including the sensor characteristics, installation procedure, data quality control protocol, and the basic analysis of each variable. We then give an example of a short-term atmospheric event that shows the monitoring capacity of the network. This dataset, which is publicly available, is planned to be updated on a near-real time and should be valuable for climate change estimation, extreme weather events diagnosis, data assimilation, weather forecasting, etc. The dataset is available at https://doi.org/10.11888/Atmos.tpdc.272721 (Ding et al., 2022).

Abstract

Using automatic weather station and reanalysis data (ERA5) from 2011 at Panda‐1 Station, situated in the katabatic region of Princess Elizabeth Land, East Antarctica, the surface energy balance was calculated using a surface temperature iteration method, and the characteristics of each energy component were analyzed. Downward shortwave and longwave radiation were the two primary energy sources during summer days with seasonal means of 346 and 142 W m−2 . The turbulent fluxes of sensible and latent heat flux represent smaller heat sources. In the annual mean, reflected shortwave radiation exceeds the upward longwave radiation with a seasonal average values of −287 W m−2 . During winter, the shortwave radiation is small, and the main energy input and output terms of the surface energy balance are downward and upward longwave radiation, with seasonal average values of 149 and −159 W m−2 , respectively. The combination of high wind speed and a large near‐surface humidity gradient during summer resulted in significant frost depositional events. The total surface frost deposition for the whole year was 24 kg m−2 , which accounted for 61% of the total accumulation (averaged over 10 years). When a high‐pressure ridge blocks cyclones and deflects fronts of low‐pressure systems to inland East Antarctica during winter, this has a significant impact on the surface energy balance at Panda 1 automatic weather station, with daily sensible and latent heat fluxes increasing by as much as 25 and 12 W m−2 , respectively. These results still contain uncertainties as we only address a single year, when interannual variability may be considerable, and we do not consider drifting snow sublimation.

47. Disentangling the Impact of Social Disadvantage on ‘Becoming Employable’: Evidence from STEM Student University-to-Work Transitions

Author

Abstract

This article aims to examine alternative explanations of social disadvantage on the university-to-work transition experiences of science, technology, engineering and mathematics (STEM) students. ‘Becoming employable’ during the university-to-work transition is reflected in three ways: students’ cognition/patterns of thinking (i.e., perceived employability); affect/emotion (i.e., anxiety); and career-related behaviour (i.e., job search and networking). To understand how social disadvantage affects ‘becoming employable’, we examine three potential explanations: students’ social background, type of higher education institution attended and individual financial strain. A cross-sectional survey design targeted at final year students in two UK Higher Education Institutions provided 288 survey responses. Findings show support for an institutional explanation to ‘becoming employable’. The study contributes to our understanding of social disadvantage during preparation for labour market entry and the ‘employable graduate’ identity construction process. Practical recommendations focus on alleviating some of the pressures on socially disadvantaged students
