Synchronized group association in little penguins, Eudyptula Minor.

Most seabirds form groups on land and at sea, but there is little information whether seabird groups are formed deliberately or randomly. We investigated whether little penguins formed groups composed of the same individuals when they crossed the beach each day over four breeding seasons (2001–2004) using an automated penguin monitoring system (APMS). We used an association matrix to determine the number of times any two birds crossed the APMS in the same group. The number of these group associations or ‘synchronized parade’ behaviour was determined for every possible pair of individuals, giving a total association value for each pair of birds during the postguard stage of the reproductive cycle. We concluded that a penguin group was composed of 5–10 individuals within 40-s intervals. Penguin groups were formed nonrandomly in years of high breeding success (2002 and 2003), but not in years of low breeding success (2001 and 2004). Age of birds was a significant factor in composition of groups. Little penguins with higher association values shared similar characteristics or ‘quality’, which in turn may increase the functional efficiency of their groups, especially if they are also foraging together. However, low association indices indicated that seeking the same associates was not a priority. It is costly for any animal to synchronize their attendance with the same individuals, so it could be beneficial to display synchronized parade behaviour in good breeding years but it could result in intraspecific competition for food during poor breeding years.

Efficient algorithm for mobile multicast using anycast group

The authors present a novel and efficient multicast algorithm that aims to reduce delay and communication cost for the registration between mobile nodes and mobility agents and solicitation for foreign agent services based on the mobile IP. The protocol applies anycast group technology to support multicast transmissions for both mobile nodes and home/foreign agents. Mobile hosts use anycast tunnelling to connect to the nearest available home/foreign agent where an agent is able to forward the multicast messages by selecting an anycast route to a multicast router so as to reduce the end-to-end delay. The performance analysis and experiments demonstrated that the proposed algorithm is able to enhance the performance over existing remote subscription and bidirectional tunnelling approaches regardless of the locations of mobile nodes/hosts

Masochistic marketing : Volvo Australia's not "so safe" strategy

Purpose – The objective is to describe a marketing approach used by Volvo in the Australian marketplace. It appears to be a rare approach and could be perceived to some extent as being “masochistic”.

Design/methodology/approach – The research is based upon a case study. The term “masochistic marketing” is introduced.

Findings – The “masochistic marketing” approach applied by Volvo in Australia should be seen as a process. It is dependent upon the outcome of a series of cause and effect relationships.

Research limitations/implications – The masochistic marketing approach may be divided into four cause-related phases, all of which create a dualistic outcome of either positive or negative effect-chains in respect to the corporate image in the marketplace and society.

Practical implications – A masochistic marketing approach is a high-risk venture. It is a challenging and demanding marketing process, because it plays on the humiliation of the corporate image itself. The core idea of the masochistic marketing approach violates, or at least appears to oppose, the fundaments of marketing.

Originality/value – Masochistic marketing is not recommended to be used as a common approach, unless a series of events has turned the corporate image in the marketplace into something that is highly undesirable and a stigma.

The health watch case - control study of leukemia and benzene:the story so far

A case–control study nested in the Health Watch cohort of petroleum industry workers, investigated whether the excess of lymphohematopoetic cancers, identified among male members of the Health Watch cohort, was associated with benzene exposure. Cases of non-Hodgkin’s lymphoma (n=31),multiple myeloma (n=15), and leukemia (n=33)were identified between 1981 and 1999. Cases were age-matched to five controls. Exposure was retrospectively estimated for each occupational history using an algorithm in a relational database. Benzene exposure measurements, supplied by Australian petroleum companies, were used to estimate exposure for specific tasks. The tasks carried out within the job, the products handled, and the technology used,were identified from interviews with contemporary colleagues. More than half of the subjects started work after 1965 and had an average exposure period of 20 years. Exposure was low, 85% of the cumulative exposure estimates were<10 ppm years. Matched analyses showed that non-Hodgkin’s lymphoma and multiple myeloma were not associated with benzene exposure. Leukemia risk, however, was significantly increased for the subjects with greater than 16 ppm years cumulative exposure, odds ratio (OR) 51.9 (5.6–477) or with greater than 0.8 ppm intensity of highest exposed job. Cumulative exposures were similar to those found in comparable studies.The inclusion of occasional high exposures, for example, as a result of spillages, reduced the ORs, when the exposure was treated as either a continuous or a categorical variable. Our data demonstrate a strong association between leukemia and modest benzene exposure. The choice of cut-point and reference group has a marked effect on the ORs, but does not change the overall conclusions.

Using large group methods to develop effective quality cultures

It has become evident that higher education institutions in the Sultanate of Oman are currently experiencing change, in particular when it involves implementing quality management systems. The underlying principles of quality management are participatory decision making. Our methods for conducting improvements in quality management, strategic planning and other topics model this principle. Large group methods or interventions involve gathering an entire organization to talk about, influence or invent needed changes (Bunker & Alban, 2002). Change is a result of purposeful social construction by organizational members. It involves a goal (approach/plan), implementation (deployment/act/so), evaluation (results/check) and modification (improvement). This paper explores the different large group methods being used in the field today and it proposes that large group methods allow a forum to overcome some of the hurdles and challenges that are being faced in Oman such as; How do you encourage sharing information in a fiercely competitive environment? And how do you establish an informal network of peers? We were witness to some of these challenges being over come when we used large group methods during various strategic planning workshops with members of staff from the different colleges in Oman. Results from the evaluations of the workshops highlighted that participants enjoyed the opportunity to network and share ideas with their peers as well as being involved in group discussions and brainstorming ideas. The paper will also propose that large group methods can be used effectively in Omani culture strengthening goals towards Omanisation.

Dancing habitus: the formation of a group (dance)

This article discusses how six individual dancers came to belong, stylistically, to a group, in a project that did not aim explicitly to create or bring about that belonging. The studio-based research project tested the creation of a group improvised dance through practising over a significant period of time with ‘scores’ or verbal propositions, usually relating to physical, bodily or movement notions such as tangling and untangling or being subject to gravity. This article looks at one question within the research: namely, whether the dancing individuals came, over time, to belong to a group, and if so, what enabled that belonging and what made the dance a group dance? The project did not centre on an objective to direct the creation of a ‘groupness’ or stylistic consistency but, rather, it supported the investigation of how this ‘groupness’ might come about.

Rewind, repeat: TV’s fame machine is oh-so retro

As much as the contemporary talent show appears to be different, there are qualities that relate to earlier versions of televised talent contests internationally and domestically. This article explores how the past iterations inform the present and its production of an internal - almost studio system - of fame.

Culture and sex education : the acquisition of sexual knowledge for a group of Vietnamese Australian young women

This paper explores how a group of Vietnamese Australian young women acquire knowledge of sexual issues, and the impact the traditional Vietnamese culture has on the acquisition of this knowledge. It is based on a qualitative study that examined the factors which shape the sexual behaviour of Vietnamese Australian young women living in Australia. A Grounded Theory methodology was employed in this investigation, and involved in-depth interviews with 15 Vietnamese Australian young women aged 18-25 years, who reside in Victoria, Australia. The findings illustrated three key elements involved in the acquisition of knowledge of sexual issues: 'Accepting parental silence', 'Exploring sources of knowledge' and 'Needing culturally targeted information'. The young women desired discussion about sexual issues but accepted that cultural 'barriers' were formidable. Their desire conflicted with the traditional familial norm of 'silence' regarding sexual matters. Consequently, knowledge was sought outside the home, specifically from peers and the media. The importance of culturally appropriate and adequate sexual discussions for Vietnamese Australian young people was stressed, so that informed decisions could be made about their sexual lives. It is imperative for young people to have adequate and appropriate sexual education so that informed and safe sexual choices can be made. For young people from diverse cultural backgrounds, this education must be culturally appropriate and accessible, taking into consideration cultural mores regarding gender and sexual matters, as well as current beliefs in the 'mainstream' youth culture.
