Project alliancing at National Museum of Australia: Collaborative process

Project alliancing is a new alternative to traditional project delivery systems, especially in the commercial building sector. The Collaborative Process is a theoretical model of people and systems characteristics that are required to reduce the adversarial nature of most construction projects. Although developed separately, both are responses to the same pressures. Project alliancing was just used successfully to complete the National Museum of Australia. This project was analyzed as a case study to determine the extent to which it could be classified as a “collaborative project”. Five key elements of The Collaborative Process were reviewed and numerous examples from the management of this project were cited that support the theoretical recommendations of this model. In the case of this project, significant added value was delivered to the client and many innovations resulted from the collective work of the parties to the contract. It was concluded that project alliances for commercial buildings offer many advantages over traditional project delivery systems, which are related to increasing the levels of collaboration among a project management team

Ecological non-linear state space model selection via adaptive particle Markov chain Monte Carlo (AdPMCMC)

We develop a novel advanced Particle Markov chain Monte Carlo algorithm that is capable of sampling from the posterior distribution of non-linear state space models for both the unobserved latent states and the unknown model parameters. We apply this novel methodology to five population growth models, including models with strong and weak Allee effects, and test if it can efficiently sample from the complex likelihood surface that is often associated with these models. Utilising real and also synthetically generated data sets we examine the extent to which observation noise and process error may frustrate efforts to choose between these models. Our novel algorithm involves an Adaptive Metropolis proposal combined with an SIR Particle MCMC algorithm (AdPMCMC). We show that the AdPMCMC algorithm samples complex, high-dimensional spaces efficiently, and is therefore superior to standard Gibbs or Metropolis Hastings algorithms that are known to converge very slowly when applied to the non-linear state space ecological models considered in this paper. Additionally, we show how the AdPMCMC algorithm can be used to recursively estimate the Bayesian Cram\'er-Rao Lower Bound of Tichavsk\'y (1998). We derive expressions for these Cram\'er-Rao Bounds and estimate them for the models considered. Our results demonstrate a number of important features of common population growth models, most notably their multi-modal posterior surfaces and dependence between the static and dynamic parameters. We conclude by sampling from the posterior distribution of each of the models, and use Bayes factors to highlight how observation noise significantly diminishes our ability to select among some of the models, particularly those that are designed to reproduce an Allee effect

Alfalfa Fertility Management for Production and Feed Quality

For many years it has been recognized that the two major limiting factors to alfalfa (Medicago sativa) growth in the upper Midwest are soil pH and exchangeable soil potassium (Brown, 1928; Hull, 1934; Lanyon and Griffith, 1988). Recent research affirms the benefits of raising pH to near neutral by adding lime to fields where alfalfa is to be grown in Wisconsin (Peters and Kelling, 1989; Peters and Kelling, 199 7)

miR-786 Regulation of a Fatty-Acid Elongase Contributes to Rhythmic Calcium-Wave Initiation in \u3cem\u3eC. elegans\u3c/em\u3e

Background: Rhythmic behaviors are ubiquitous phenomena in animals. In C. elegans, defecation is an ultradian rhythmic behavior: every ∼50 s a calcium wave initiating in the posterior intestinal cells triggers the defecation motor program that comprises three sequential muscle contractions. Oscillatory calcium signaling is central to the periodicity of defecation. The posteriormost intestinal cells function as the pacemaker for this rhythmic behavior, although it is unclear how the supremacy of these cells for calcium-wave initiation is controlled. Results: We describe how the loss of the mir-240/786 microRNA cluster, which results in arrhythmic defecation, causes ectopic intestinal calcium-wave initiation. mir-240/786 expression in the intestine is restricted to the posterior cells that function as the defecation pacemaker. Genetic data indicate that mir-240/786 functions upstream of the inositol 1,4,5-trisphosphate (IP3) receptor. Through rescue analysis, it was determined that miR-786 functions to regulate defecation. Furthermore, we identified elo-2, a fatty-acid elongase with a known role in defecation cycling, as a direct target for miR-786. We propose that the regulation of palmitate levels through repression of elo-2 activity is the likely mechanistic link to defecation. Conclusions: Together, these data indicate that miR-786 confers pacemaker status on posterior intestinal cells for the control of calcium-wave initiation through the regulation of elo-2 and, subsequently, palmitate levels. We propose that a difference in fatty-acid composition in the posterior intestinal cells may alter the activities of membrane proteins, such as IP3-receptor or TRPM channels, that control pacemaker activity in the C. elegans intestine

ECONOMICS OF SEQUESTERING CARBON IN THE U.S. AGRICULTURAL SECTOR

Atmospheric concentrations of greenhouse gases can be reduced by withdrawing carbon from the atmosphere and sequestering it in soils and biomass. This report analyzes the performance of alternative incentive designs and payment levels if farmers were paid to adopt land uses and management practices that raise soil carbon levels. At payment levels below $10 per metric ton for permanently sequestered carbon, analysis suggests landowners would find it more cost effective to adopt changes in rotations and tillage practices. At higher payment levels, afforestation dominates sequestration activities, mostly through conversion of pastureland. Across payment levels, the economic potential to sequester carbon is much lower than the technical potential reported in soil science studies. The most cost-effective payment design adjusts payment levels to account both for the length of time farmers are willing to commit to sequestration activities and for net sequestration. A 50-percent cost-share for cropland conversion to forestry or grasslands would increase sequestration at low carbon payment levels but not at high payment levels.Carbon sequestration, greenhouse gas mitigation, afforestation, conservation tillage, no-till, incentive design, leakage, carbon stock, permanence, Environmental Economics and Policy,

Social Media and Negative Word of Mouth: Strategies for Handing Unexpecting Comments

Increased usage of social media by consumers impacts businesses that find it necessary to participate to connect with customers. Because social media is conversational in nature, marketers have little control over the message, unlike more traditional forms of marketing communication. The purpose of this paper is to flesh out the tensions that exist as marketers deal with consumer-generated negative social media messages and present possible responses for marketers dealing with this form of negative word of mouth (WOM). Its contribution lies in unpacking options for companies dealing with such negative social media. Case studies and a conceptual model identifying possible strategies for businesses dealing with negative social media attacks are presented. The five general strategies identified are: delay, respond, partner, legal action, and censorship. Understanding and use of these strategies can assist businesses in dealing with negative WOM and can potentially help them protect their brand image and profitability

Broadening the concept of school: how a re-configuration of school must be inclusive of students who are "put at" a disadvantage

This thesis critically examines how students enrolled in state-funded schools can be ‘put at’ a disadvantage. I do this through examining two techniques of exclusion that stimulate student disconnection from school: first, the ways in which standards-based and performativity-driven learning outcomes are implemented to shape how student success is determined. Secondly, I examine how discourses around power control curriculum and student identity instil monological learning structures that normalises standards-based learning outcomes. Challenging this, I allow the voices of my co-researchers, the students in my thesis, to speak back to confront these school-based policies that allow disconnection to occur. Examining school policy and student voice at the point where they intersect allowed me to undertake an evaluation of how schools adversely affect students, and what students say they want from their experience of schooling. The final theme I develop is based on student and agency worker voice and what they say school-based learning should become. Relational learning and learning that develops students ethically emerged as fundamental strengths of what enriching learning transactions should look like. I argue that creating relational learning spaces develop challenging environments that can lead students to ethically understand their identity within complex social and cultural lifestyles. I argue that the ways in which schools are organised to administer time and space must be radically overhauled if this is to be achieved.Doctor of Philosoph
