An exploratory study of "best practice" in environmentally sustainable event management in Australian public events

© 2018 Cognizant, LLC. This study seeks to provide insights into "best practice" in the area of environmentally sustainable event management in Australian public events. In performing this role, it aims to: determine forces acting to drive engagement with environmental management practices; identify the key challenges event owners and managers face in seeking to adopt such practices; determine types of environmentally sustainable practices currently in use; establish how events are measuring their environmental performance; and identify those factors serving to facilitate or inhibit engagement by events with an environmental agenda. The article begins with a literature review of research germane to the study, along with an overview of the methodology employed. Key findings emerging from the application of this methodology suggest that actions in this area: have increasingly become an aspect of overall event planning; target multiple areas with the potential to generate environmental impacts; are driven primarily by organizer values and attendee and community expectations; and face constraints linked largely to the availability of resources, expertise, and time. This article acknowledges that the planning and delivery of environmentally sustainable events has become one of the critical challenges facing public event management, and as such it seeks to make a meaningful contribution to both the growing academic literature in this area, and equally importantly, to industry practice

The Attributional Double Standard : Actor-Observer Differences in Predicting the Relationship Between Attitudes and Behaviors

It was hypothesized that subjects who took the role of interaction observers ration than actors would predict a closer relationship between attitudes and behaviors and would report greater confidence in behavioral predictions derivable from an actor\u27s attitude statements. One hundred sixty-eight subjects assumed the role of either actor or observer in scenarios of group interactions in which a central person made a statement about a particular attitude object. As predicted, subjects in the observer role reported that specific future behaviors (e.g., loaning money, helping to study for a test) had a greater likelihood of occurrence following an attitude statement (e.g., I like Pat ) than did subjects in the actor role, and observers were more confident than actors in these predictions. In addition, the favorability of the attitude statement was directly related to the strength of predictions, and the central person\u27s familiarity with the audience was directly related to confidence in predictions. Observers apparently view attitude statements as reliable indications of internal dispositions that serve as a potential cause of subsequent behaviors, while actors view attitude statements as tenuous orientations that can be modified in accord with future situational contingencies

On the total mean curvature of non-rigid surfaces

Using Green's theorem we reduce the variation of the total mean curvature of a smooth surface in the Euclidean 3-space to a line integral of a special vector field and obtain the following well-known theorem as an immediate consequence: the total mean curvature of a closed smooth surface in the Euclidean 3-space is stationary under an infinitesimal flex.Comment: 4 page

Collisions of particles in locally AdS spacetimes I. Local description and global examples

We investigate 3-dimensional globally hyperbolic AdS manifolds containing "particles", i.e., cone singularities along a graph $\Gamma$. We impose physically relevant conditions on the cone singularities, e.g. positivity of mass (angle less than $2\pi$ on time-like singular segments). We construct examples of such manifolds, describe the cone singularities that can arise and the way they can interact (the local geometry near the vertices of $\Gamma$). We then adapt to this setting some notions like global hyperbolicity which are natural for Lorentz manifolds, and construct some examples of globally hyperbolic AdS manifolds with interacting particles.Comment: This is a rewritten version of the first part of arxiv:0905.1823. That preprint was too long and contained two types of results, so we sliced it in two. This is the first part. Some sections have been completely rewritten so as to be more readable, at the cost of slightly less general statements. Others parts have been notably improved to increase readabilit

Self-Presentational Determinants of Sex Differences in Leadership Behavior

Men and women placed in leadership positions communicated information about their skills and abilities to their subordinates. Although leaders’ perceptions of their abilities, group members’ knowledge of their leader’s abilities, and the specific skills needed by the leader were all manipulated in the experimental setting, self-presentations of ability were primarily determined by sex role stereotypes rather than by situational factors. Results indicated that (1) male leaders emphasized their social influence and task abilities; (2) female leaders emphasized their interpersonal, socioemotional abilities; and (3) group members felt task ability, as compared to interpersonal ability, was a far more important skill for a leader to possess. It was concluded that sex differences in male and female leadership behavior may be due to self-presentational conformity to sex roles, and that this conformity enhances males’ leadership effectiveness while detracting from females’ leadership effectiveness

Distributed utterances

I propose an apparatus for handling intrasentential change in context. The standard approach has problems with sentences with multiple occurrences of the same demonstrative or indexical. My proposal involves the idea that contexts can be complex. Complex contexts are built out of (“simple”) Kaplanian contexts by ordered n-tupling. With these we can revise the clauses of Kaplan’s Logic of Demonstratives so that each part of a sentence is taken in a different component of a complex context. I consider other applications of the framework: to agentially distributed utterances (ones made partly by one speaker and partly by another); to an account of scare-quoting; and to an account of a binding-like phenomenon that avoids what Kit Fine calls “the antinomy of the variable.

New Luttinger liquid physics from photoemission on Li0.9_{0.9}Mo6_6O17_{17}

Temperature dependent high resolution photoemission spectra of quasi-1 dimensional Li$_{0.9}$Mo$_6$O$_{17}$ evince a strong renormalization of its Luttinger liquid density-of-states anomalous exponent. We trace this new effect to interacting charge neutral critical modes that emerge naturally from the two-band nature of the material. Li$_{0.9}$Mo$_6$O$_{17}$ is shown thereby to be a paradigm material that is capable of revealing new Luttinger physics.Comment: 4 pages, 3 figures. Accepted for publication by Phys. Rev. Let

Luttinger liquid ARPES spectra from samples of Li0.9_{0.9}Mo6_6O17_{17} grown by the temperature gradient flux technique

Angle resolved photoemission spectroscopy line shapes measured for quasi-one-dimensional Li$_{0.9}$Mo$_6$O$_{17}$ samples grown by a temperature gradient flux technique are found to show Luttinger liquid behavior, consistent with all previous data by us and other workers obtained from samples grown by the electrolyte reduction technique. This result eliminates the sample growth method as a possible origin of considerable differences in photoemission data reported in previous studies of Li$_{0.9}$Mo$_6$O$_{17}$.Comment: Some text adde

Comparing and combining process-based crop models and statistical models with some implications for climate change

We compare predictions of a simple process-based crop model (Soltani and Sinclair 2012), a simple statistical model (Schlenker and Roberts 2009), and a combination of both models to actual maize yields on a large, representative sample of farmer-managed fields in the Corn Belt region of the United States. After statistical post-model calibration, the process model (Simple Simulation Model, or SSM) predicts actual outcomes slightly better than the statistical model, but the combined model performs significantly better than either model. The SSM, statistical model and combined model all show similar relationships with precipitation, while the SSM better accounts for temporal patterns of precipitation, vapor pressure deficit and solar radiation. The statistical and combined models show a more negative impact associated with extreme heat for which the process model does not account. Due to the extreme heat effect, predicted impacts under uniform climate change scenarios are considerably more severe for the statistical and combined models than for the process-based model
