A methodology for the generation and evaluation of biorefinery process chains, in order to identify the most promising biorefineries for the EU
The topic of bioenergy, biofuels and bioproducts remains at the top of the current political and research agenda. Identification of the optimum processing routes for biomass, in terms of efficiency, cost, environment and socio-economics is vital as concern grows over the remaining fossil fuel resources, climate change and energy security. It is known that the only renewable way of producing conventional hydrocarbon fuels and organic chemicals is from biomass, but the problem remains of identifying the best product mix and the most efficient way of processing biomass to products. The aim is to move Europe towards a biobased economy and it is widely accepted that biorefineries are key to this development. A methodology was required for the generation and evaluation of biorefinery process chains for converting biomass into one or more valuable products that properly considers performance, cost, environment, socio-economics and other factors that influence the commercial viability of a process. In this thesis a methodology to achieve this objective is described. The completed methodology includes process chain generation, process modelling and subsequent analysis and comparison of results in order to evaluate alternative process routes. A modular structure was chosen to allow greater flexibility and allowing the user to generate a large number of different biorefinery configurations The significance of the approach is that the methodology is defined and is thus rigorous and consistent and may be readily re-examined if circumstances change. There was the requirement for consistency in structure and use, particularly for multiple analyses. It was important that analyses could be quickly and easily carried out to consider, for example, different scales, configurations and product portfolios and so that previous outcomes could be readily reconsidered. The result of the completed methodology is the identification of the most promising biorefinery chains from those considered as part of the European Biosynergy Project
Emergency Services Workforce 2030
Australia’s emergency management sector sits within an environment that is becoming ever more complex, dynamic and uncertain. This is due to factors like a growing population, changing climate, social and cultural change, and the impact of new technologies. At the same time, the nature of how we work, in both paid and voluntary ways, is also changing. Work is greatly influenced by changes in technology and lifestyle, and by increasing levels of interconnectivity and cross-boundary collaboration.
In this dynamic context, planning for the sustainability, effectiveness and wellbeing of the future emergency management workforce takes on considerable importance.
The workforces of Australia’s fire, emergency services and rural land management agencies (referred to in this report as emergency service organisations) are crucial to Australia’s emergency management capability. These workforces include career and volunteer members, they also include first responders as well as professional, technical, and administrative support staff and volunteers (hereafter referred to collectively as the emergency service workforce).
This report provides a consolidated, overview picture of emerging workforce challenges and opportunities likely to face emergency service organisations over the coming decade. It is a first step in bringing together the wide range of research that can inform and strengthen strategic workforce planning in these organisations.
The report presents a high-level summary of key trends and developments highlighted in research from beyond the emergency management sphere. It identifies potential implications of these trends and developments for the future emergency service workforce. It also highlights key Bushfire and Natural Hazards Cooperative Research Centre (CRC) affiliated research that can assist workforce planners to understand and respond to these implications.
The bulk of the combined emergency service workforce are volunteers. According to the Productivity Commission, there were around 212,293 fire service volunteers and 23,897 state and territory emergency service volunteers across emergency service organisations in Australia in 2017-18 (Commonwealth of Australia, 2019). Volunteers therefore formed around 91% of the fire service workforce, and 97% of the state and territory emergency service workforce in that year. Furthermore, given the geographic size, changing risk profile, and demographic shifts in Australia, a heavy reliance on volunteers is likely to continue into the future. As such, volunteers and volunteering issues form a key component of the terrain covered in this report.
While focusing on the emergency service workforce, this report is also based on recognition that the emergency services are part of a wider emergency management workforce that is also diverse and changing. The complete emergency management workforce extends far beyond the emergency services to include the volunteer and paid workforces of not-for-profits active in recovery, local governments, wider community sector and faith-based organisations, government departments, private businesses and more. Increasingly, under the influence of changing community expectations, and policy goals of community resilience, shared responsibility, and clear risk ownership (COAG, 2011; Commonwealth of Australia, 2018), ‘unaffiliated’ community members and groups are also recognised as a valuable part of the emergency management workforce (AIDR, 2017).
Consequently, the future emergency management workforce is not going to be restricted to the affiliated volunteer and paid workforces of formal emergency service organisations. Therefore, this report considers the future emergency service workforce within the context of how it interacts with and forms a part of the wider emergency management workforce
Emergency Services Workforce 2030: Changing landscape literature review
The Changing Landscape Literature Review collates a high-level evidence base around seven major themes in the changing landscape (i.e., the external environment) that fire, emergency service, and rural land management agencies operate in, and which will shape workforce planning and capability requirements over the next decade. It is an output of the Workforce 2030 project and is one of two literature reviews that summarise the research base underpinning a high-level integrative report of emerging workforce challenges and opportunities, Emergency Services Workforce 2030.
Workforce 2030 aimed to highlight major trends and developments likely to impact the future workforces of emergency service organisations, and their potential implications. The starting point for the project was a question:
What can research from outside the sphere of emergency management add to our knowledge of wider trends and developments likely to shape the future emergency services workforce, and their implications?
The seven themes included in the Changing Landscape Literature Review are: 1) demographic changes, 2) changing nature of work, 3) changes in volunteering, 4) physical technology, 5) digital technology, 6) shifting expectations, and changing risk. A second, accompanying literature review, the Changing Work Literature Review, focuses on another nine themes related to emergency service organisation’s internal workforce management approaches and working environments

Estimation for a Partial-Linear Single-Index Model
In this paper, we study the estimation for a partial-linear single-index
model. A two-stage estimation procedure is proposed to estimate the link
function for the single index and the parameters in the single index, as well
as the parameters in the linear component of the model. Asymptotic normality is
established for both parametric components. For the index, a constrained
estimating equation leads to an asymptotically more efficient estimator than
existing estimators in the sense that it is of a smaller limiting variance. The
estimator of the nonparametric link function achieves optimal convergence
rates; and the structural error variance is obtained. In addition, the results
facilitate the construction of confidence regions and hypothesis testing for
the unknown parameters. A simulation study is performed and an application to a
real dataset is illustrated. The extension to multiple indices is briefly
sketched.Comment: 43 pages and 2 figure

Satisfying Newcomers’ Needs: The Role of Socialization Tactics and Supervisor Autonomy Support
© 2020, Springer Science+Business Media, LLC, part of Springer Nature.
We investigate a novel approach to newcomer socialization based on self-determination theory (SDT). A core assumption of SDT is that when social contexts support basic psychological needs for autonomy, competence, and relatedness, people are more likely to integrate new experience effectively and thrive in their environment. We sought to examine the role of psychological need support within the context of newcomer socialization and the period of early entry where newcomers learn their new role and become integrated within the organization. We propose that organizational socialization tactics and perceived autonomy-supportive supervision jointly influence newcomers’ basic psychological needs and, in turn, their organizational commitment and withdrawal cognitions. Results from structural equation modeling analyses from a time-lagged study of 489 MBA interns supported our hypothesized model. There were significant indirect effects of institutionalized socialization tactics and supervisor autonomy support on both affective organizational commitment and withdrawal cognitions, via psychological need satisfaction. Use of institutionalized tactics also was negatively associated with interns’ specific need for autonomy, suggesting that individualized tactics may play a role in supporting newcomers’ sense of self-determination. A post hoc moderation analysis further suggested a substitutive pattern in the interaction between supervisor autonomy support and institutionalized tactics, emphasizing the central role that supervisors play in newcomer socialization, particularly when it pertains to newcomers’ psychological need satisfaction. Our results indicate that SDT is a promising theoretical framework for studying newcomer adjustment
