Soil carbon sequestration and associated economic costs for farming systems of the Indo-Gangetic Plain : a meta-analysis

Soil organic carbon sequestration rates over 20 years based on the Intergovernmental Panel for Climate Change (IPCC) methodology were combined with local economic data to determine the potential for soil C sequestration in wheat-based production systems on the Indo-Gangetic Plain (IGP). The C sequestration potential of rice–wheat systems of India on conversion to no-tillage is estimated to be 44.1 Mt C over 20 years. Implementing no-tillage practices in maize–wheat and cotton–wheat production systems would yield an additional 6.6 Mt C. This offset is equivalent to 9.6% of India's annual greenhouse gas emissions (519 Mt C) from all sectors (excluding land use change and forestry), or less than one percent per annum. The economic analysis was summarized as carbon supply curves expressing the total additional C accumulated over 20 year for a price per tonne of carbon sequestered ranging from zero to USD 200. At a carbon price of USD 25 Mg C−1, 3 Mt C (7% of the soil C sequestration potential) could be sequestered over 20 years through the implementation of no-till cropping practices in rice–wheat systems of the Indian States of the IGP, increasing to 7.3 Mt C (17% of the soil C sequestration potential) at USD 50 Mg C−1. Maximum levels of sequestration could be attained with carbon prices approaching USD 200 Mg C−1 for the States of Bihar and Punjab. At this carbon price, a total of 34.7 Mt C (79% of the estimated C sequestration potential) could be sequestered over 20 years across the rice–wheat region of India, with Uttar Pradesh contributing 13.9 Mt C.

The noblest of professions : schoolmasters at Hastings 1872-1894

The Noblest of Professions: Schoolmasters at Hastings 1872-1894 is a skilfully developed study of educational developments outside the Australian metropolises and in a small, but significant, pioneering rural community in the late colonial period. It is an important contribution to the formerly neglected field of local and regional history in Australia. It extends our knowledge of the life experiences of the schoolmaster in an isolated community and the regard local people had for him, together with the significant and varied social and leadership roles he played regularly and occasionally in rural affairs. The rural schoolmaster and his concerns are vividly brought to life in a compelling portrayal in this book. In all a very significant contribution to Australian history and to the history of education in its regional and local context.

Disobedient Citizens : Press Depictions of Striking School Teachers in NSW and Anti-Vietnam War Demonstrators in NSW and Victoria in 1968

Across Australia in 1968, students demonstrating against the Vietnam War engaged in confrontational behaviour. The metropolitan daily newspapers,the most important source of news for most people, enthusiastically reported the scenes. The demonstrations were exciting. Sensational headlines and photographs captured the interest of readers and influenced their opinions. But radical opposition to government policies at the time was not limited to university students opposing the Vietnam War. Teachers had become increasingly critical of conditions in schools, with Victorian secondary school teachers having stopped work on a number of occasions since 1965. In October 1968, both primary and secondary school teachers in New South Wales participated in eastern Australia’s first state-wide teachers’ strike. As Sydney’s Sun commented on 1 October 1968, “The teachers’ strike threw the ... education system into chaos ... A huge proportion of the State’s 2764 schools were silent and empty.” Similarities with the anti-war demonstrations were obvious. Although not as confrontational, the New South Wales teachers’ strike was a publicity-seeking action. This examination of the teachers’ more restrained, but more effective, approach to challenging government policies provides a new voice and vision to our understandings of the diverse nature of radicalism in Australia in the 1960s.

Introduction

This introduction examines sixteen authors who have contributed to New Voices, New Visions: Challenging Australian Identities and Legacies. The editors explain that the authors draw on ideas, concepts, and theories about nation, identity, space, place,and power in order to rethink stories or reread large-scale and everyday media, private, or public events in new ways. In many cases, the authors are promoting debate on topics where a single viewpoint currently predominates. These authors are introducing to readers new visions and new voices about Australian society and the Australian identity. The editors also draw on the many books about Captain/Governor William Bligh to exemplify how history is constantly being reinterpreted, with new information aiding the reader’s understanding.

Campbell, Alan Johnston (1895–1982)

Born in 1895, Alan Johnston Campbell was a grazier and political party organiser. In December 1914 he enlisted in the Australian Imperial Force and saw action with the 2nd Light Horse Regiment at Gallipoli and, as a lance corporal, in the Sinai and Palestine. After the war Campbell became active in the Roma branch of the Maranoa Graziers’ Association. In 1935, at Roma, he formed one of the first branches of the Queensland Country Party. In 1943, Campbell was elected president of the QCP. Impressed by the Australian Labor Party’s organisation, Campbell centralised power and rebuked parliamentarians whom he believed were neglecting their constituents. By 1951 the highly disciplined structure had attracted 35,000 members. Campbell died in 1982.

Determining the optimal proportion of design in design-build request for proposals (RFPs)

The design-build (DB) system is a popular and effective delivery method of construction projects worldwide. After owners decide to procure their projects through the DB system, they may wish to determine the optimal proportion of design to be provided in the DB request for proposals (RFPs), which serve as solicitations for design-builders and describe the scope of work. However, this presents difficulties to DB owners and there is little, if any, systematic research in this area. This paper reports on an empirical study in the USA entailing both an online questionnaire survey and Delphi survey to identify and evaluate the factors influencing owners’ decisions in determining the proportion of design to include in DB RFPs. Eleven factors are identified, i.e. (1) clarity of project scope; (2) applicability of performance specifications; (3) desire for design innovation; (4) site constraints; (5) availability of competent design-builders; (6) project control requirements; (7) user group involvement level; (8) third party requirements; (9) owner experience with DB; (10) project complexity; and (11) schedule constraints. A statistically significant agreement on the eleven factors was also obtained from the (mainly non-owner) Delphi experts. Although some of the experts hold different opinions on how these factors affect the proportion of design, these findings furnish various stakeholders with a better understanding of the delivery process of DB projects and the appropriate provision of project information in DB RFPs. As the result is mainly industry opinion concerning the optimal proportion of design, in addition and for completeness, future studies should be conducted to obtain a big picture of the optimal proportion of design by means of seeking owners’ inputs.

R&D investment in green building initiatives in Western Australia

This paper reports on a current case study of green building initiatives implemented by the Western Australian government in the past decade. The intent is to provide a qualitative understanding of past R&D investments in the Australian built environment. The case method was selected to illustrate three sector-based investments, one of which is reported on here. The conceptual framework underpinning interview design and data analysis uses dynamic capability, absorptive capacity and open innovation theories to better understand the organisational environment in which these initiatives were implemented. Data has been thematically coded to criteria identified from the literature to illustrate organisational characteristics which may have contributed to dissemination and impact. The results will be combined with two further case studies (construction safety and digital modelling), to inform this research. This industry supported project will conclude by developing policy guidelines for future R&D investment in the built environment.
