Following the Rena grounding and oil spill in the Bay of Plenty, New Zealand, an Incident Command Centre was established which, among other tasks, coordinated a volunteer clean-up effort. We interviewed volunteers and organisers to gain insight into the efficacy of the volunteer coordination effort. Volunteers praised the system of communication and the involvement of indigenous groups. They expressed a desire for better training, more flexibility and community autonomy, a quicker uptake of volunteer support, and the use of social media. Locating the Incident Command Centre in a single site aided interaction between experts, and the sharing of resources. Overall, the volunteer coordination was considered a success. © 2014 John Wiley & Sons Ltd. Source

The IT Industry and the wider media are abuzz with the phrase "cloud computing" and most of us have no idea what this latest terminology means. This paper starts by addressing the question - "what is cloud computing, and provides an understanding of the technology?" Cloud computing is related to technologies that has been around for ages, however, what can be done differently with the same technology when integrated with Internet is cloud computing. Individuals who might be considering cloud computing services for personal use will also benefit by the information provided. Web sites like Flickr, FaceBook, YouTube and others are used to store and share personal photos, music and videos for free. Easy as: 1). Register, 2). Upload, 3). Share. Free and easy, there has to be a downside, and there is awareness regarding this. There is information regarding cloud computing for businesses! Businesses, who wish to get on the "flight to the clouds" like their peers to keep their heads above the "cloud" and competition. With cloud service providers, businesses can tap into the IT services that they need, when they need, for as long as they need; without investing in any IT infrastructure. The result is a far more agile and cost-effective IT services and this paper looks at how and why. After looking at the good of cloud computing, the bad, and the ugly is revealed. Not all our experiences on the Internet have been totally positive. A range of security and trust issues exist. Individuals and businesses ask is "how secured are their information once it is with the cloud service providers?" There is analysis on the ownership of data and information stored with the cloud service providers and taxonomy of data that you post on social networking web sites. Finally, anecdotes about cloud computing that support our endeavour to compute in the cloud. Cloud computing is not a hype, it is a reality. Cloud computing is not a fad, it is here to stay. The question is no longer "will cloud computing happen?" but "how you are going to exploit this technology?". © 2012 Springer-Verlag. Source

Induced-swimming can improve the growth and feed conversion efficiency of finfish aquaculture species, such as salmonids and Seriola sp., but some species, such as Atlantic cod, show no or a negative productivity response to exercise. As a possible explanation for these species-specific differences, a recent hypothesis proposed that the applicability of exercise training, as well as the exercise regime for optimal growth gain (ER opt growth), was dependent upon the size of available aerobic metabolic scope (AMS). This study aimed to test this hypothesis by measuring the growth and swimming metabolism of hapuku, Polyprion oxygeneios, to different exercise regimes and then reconciling the metabolic costs of swimming and specific dynamic action (SDA) against AMS. Two 8-week growth trials were conducted with ERs of 0.0, 0.25, 0.5, 0.75, 1 and 1.5 body lengths per second (BL s-1). Fish in the first trial showed a modest 4.8% increase in SGR over static controls in the region 0.5-0.75 BL s-1 whereas the fish in trial 2 showed no significant effect of ER on growth performance. Reconciling the SDA of hapuku with the metabolic costs of swimming showed that hapuku AMS is sufficient to support growth and swimming at all ERs. The current study therefore suggests that exercise-induced growth is independent of AMS and is driven by other factors. © 2014 Khan, Trembath, Pether, Bruce, Walker and Herbert. Source

This paper proposes a generational model genetic algorithm-based system for solving real-world large scale set partitioning problems (SPP). The SPP is an important combinatorial optimization and has many applications like airline crew scheduling. Two improved genetic algorithm (GA) components are introduced and applied to the generational model GA system that can effectively find feasible solutions for difficult and large scale set partitioning problems. The two components are the grouping crossover operator and a modified local optimizer. The experimental results in this research show that the performance of this GA based system is capable of producing optimal or near-optimal solutions for large scale instances of SPP. Source

Since the Ornithological Society of New Zealand (OSNZ) was founded in 1939 its primary objective has been the collection and dissemination of information on New Zealand's birds. For 70 years the Society has maintained databases on all aspects of the behaviour, population sizes and movements of New Zealand's avifauna. This paper summarises what information members of the OSNZ collect and curate and discusses an Internet initiative (eBird) the Society has recently put in place to allow members to record observations and give researchers easy access to these data. © New Zealand Ecological Society.
