Using AMF inoculum to improve the nutritional status of Prunella vulgaris plants in green roof substrate during establishment

Arbuscular mycorrhizal fungi (AMF) have been shown to improve the growth, health, nutrient uptake, flowering and drought tolerance of many terrestrial plant species. Green roofs are generally deficient in nutrients, organic matter and water, and therefore AMF could be extremely beneficial in improving green roof plant performance. Despite this there is a lack of empirical research into artificially introducing AMF into green roof substrates. In this study, a commercial AMF inoculum was applied to Prunella vulgaris green roof plugs grown in small modules on a flat roof in Sheffield, UK. The modules were filled with commercial green roof substrate (80% small particle sized crushed brick, 20% green waste compost) to a depth of 100 mm. AMF inoculum was applied as four treatments: (i) directly with plug, (ii) mixed evenly into surrounding substrate, (iii) split between plug and substrate, (iv) control treatment with no inoculum added. Significantly greater levels of AMF colonisation of P. vulgaris roots was detected in all AMF treatments compared to the control. Low levels of AMF colonisation of P. vulgaris roots were also observed in the control treatment, confirming that low levels of AMF inoculum were present in this commercial substrate. Shoot phosphorous (P) concentration was improved in all AMF treatments, however there was no significant effect of any AMF treatment on P. vulgaris growth rate or biomass production. The highest AMF colonisation of P. vulgaris roots was observed when AMF inoculum was directly added to just the plug. Promisingly, P. vulgaris flowering time at the end of the first growing season was also extended in the plug AMF treatment only. This study has confirmed that commercial AMF inoculum can be used to successfully colonise plants and introduce AMF networks into green roof substrate. Although AMF inoculum was naturally present in the substrate used in this study, levels were extremely low, and unlikely to have any significant effect on plants. This study indicates that care should be taken in the use of AMF inoculum on green roofs, as the growth and health benefits of AMF are not always immediately apparent for green roof plants. In addition much more research is required in order to fully assess the extent of the benefits of AMF on green roof plants and to determine if their use can be financially viable

Enabling organisational cultural change using systemic strategic human resource management - a longitudinal study

The paper reports on a longitudinal assessment of sustained organizational cultural change in the Australian Taxation Office. Results from a major action research change project are provided. A clear finding from this research is that the cultural change had been sustained through the systemic application of strategic human resource management.Conference program : http://www.anzamconference.org/docs/ANZAM2010_Program_At_A_Glance.pd

A model for the implementation of strategic human resource management

This paper has been developed out of an action research project involving the Australian Taxation Office (ATO). One of the outcomes of this project was the development of a model for the implementation of Strategic Human Resource Management (SHRM) for the purpose of cultural change and/or alignment to business strategy.The paper brings together many of the theories that have arisen in SHRM in the last decade or so, including theories around human capital, the resource-based view, HR configuration, HR architecture, vertical and horizontal fit, HR systems and HR roles.<br /

The Use of Soft Systems Methodology As a Tool for Creativity

Soft Systems Methodology is a tool that is especially useful in diagnosing and addressing organisational problems and designing new systems in cultures that are characterised by pluralistic views and values. This paper demonstrates how SSM workshops in a large government agency resulted in a high level of creativity. SSM is then proposed as a methodology which could enhance group creativity in organizational design contexts

A model to enable organisational cultural change using systemic strategic human resource management

Cultural change in organisations is both difficult to implement and hard to achieve. In this paper, theory from strategic human resource management, organisational cultural change, systemic thinking and practice, and punctuated equilibrium, is integrated in order to build a model for organisational culture change. Evidence is provided showing the capacity of the model to enable researchers and organisational change agents to improve the success of organisational cultural change programs.<br /

Exploring factors driving social recruiting: the case of Australian organisations

This study identifies key factors driving the organizational adoption of Social Recruiting (SR) technologies, such as LinkedIn, Facebook, and Twitter. The Technology, Organization and Environment (TOE) framework, as an initial exploratory approach, is used to identify underlying factors of new technology adoption. Qualitative evidence collected from twelve Australian firms serves to specifically categorise key determinants of the organizational adoption of social recruiting technologies. It is found that, apart from several technology, organization and environment factors that significantly influence the organizational decision-making with reference to social recruiting, top management support is seen as imperative for successful adoption of recruiting technologies. Formalisation, comprehensiveness, and strategic orientation of organizational human resource departments are closely linked to adoption of social recruiting at the firm level. In addition, job applicants&rsquo; readiness and local success stories have driven firms to adopt social recruiting technologies. The study extends and modifies the TOE model to provide the theoretical foundations of social recruiting in the context of Australian organizations and help human resource professionals and practitioners to gain a better understanding of key drivers of organizational social recruiting
