Effectively capturing user sessions on the Web using Web server logs

Caldera, Amithalal, University of Western Sydney, College of Science, Technology and Environment, School of Computing and Information Technology January 2005 (has links)
The usage of Web sites has been of interest to Web administrators and researchers ever since the Web started. Analysis of Web site usage data helps to understand the behaviour of its users, which is very important, as many important decisions can be made based on it. The user behaviour may be deduced by knowing all the activities each user does from the time s/he starts a session on the Web site until s/he leaves it, which is collectively called a user session. As Web server logs explicitly record the browsing behaviour of site users and are readily and economically available, this thesis explores the use of Web server logs in capturing user sessions on Web. In order to protect users’ privacy, the standard Web server logs in general do not record the user identities or similar measures to uniquely identify the users. This thesis concentrates on heuristic strategies to infer user sessions. The heuristics exploit the background knowledge of user navigational behaviour recorded in the standard Web server logs without requiring additional information through cookies, logins and session ids. They identify relationships that may exist among the log data and make use of them to assess whether requests registered by the Web server can belong to the same individual and whether these requests were performed during the same visit. Researchers have proposed several heuristics, which were adversely affected by proxy servers, caching and undefined referrers. The thesis proposes new heuristics, which effectively address all the limitations, thus extending the work in this field. It also introduces a set of measures to quantify the performance of the heuristics and uses them to investigate their efficiency based on logs from three Web sites and makes recommendations for the Web sites to devise their own heuristics. The investigation has shown satisfactory results and the new heuristics are applicable to wider range of Web sites. / Doctor of Philosophy (PhD)

Sea Turtles and the Environmental Management of Industrial Activities in North West Western Australia

Pendoley@newton.dialix.com.au, Kellie Lee Pendoley January 2005 (has links)
The nesting demographics of sea turtles using beaches within the Barrow, Lowendal, Montebello (B-L-M) island complex on the North West Shelf of Western Australia were examined in the context of their spatial and temporal distribution and potential for exposure to industrially based artificial light sources. The distribution of overnight turtle tracks throughout the island complex confirmed high density nesting of Chelonia mydas (green turtles) on deep, sandy and high energy beaches and Natator depressus (flatback turtles) on deep, sandy and low energy beaches, while Eretmochelys imbricata (hawksbill turtle) tracks were most visible on shallow, sandy beaches adjacent to near shore coral reef habitat. The three species exhibited a summer nesting peak. Hawksbill turtles commenced nesting in September and continued through to January, green turtles commenced in November and decreased in March. Flatback turtles displayed the most constrained nesting season reported to date in Australia with 86% of the animals visits recorded in December and January only. Nesting population sizes estimated for the three species suggest that on a national scale the B-L-M complex is a moderately large green turtle and a large flatback rookery site. The hawksbill rookery is large on an international scale. While none of the green turtle nesting beaches fell within a 1.5 km radius of industrially based artificial light sources an estimated 42% of nesting flatback turtles and 12% of nesting hawksbill turtles were potentially exposed to these light sources. Testing of green turtle and hawksbill hatchling response to different wavelengths of light indicate that hatchlings from the B-L-M region respond to low wavelength much like hatchlings tested in North America (Witherington 1992a). Flatback hatchlings displayed a similar preference for low wavelength light however their responses to discrete light wavelengths between 400 nm and 700 nm suggest that this species may not discriminate well between wavelengths that lie between 450 nm and 550 nm. This response may be related to the rapid attenuation of visible light that occurs in the turbid near shore habitats favoured by this species. Field based arena studies carried out to investigate hatchling behaviour on nesting beaches with light types commonly used in industrial settings found green turtle and flatback hatchlings are significantly attracted to these lights compared to controls. Lights that emit strongly in the low wavelength range (i.e. metal halide and fluorescent) caused hatchling misorientation at lower intensities than the test light that emitted relatively poorly in this range (high pressure sodium vapour). Hawksbill hatchlings tested in situ under the influence of actual oil and gas onshore and offshore facility based lighting were disrupted from the most direct line to the ocean by these light emissions. Emergence fan mapping methods that measure hatchling orientation on nesting beaches were refined and are proposed as an alternative monitoring tool for use on beaches that are logistically difficult to access for large scale experimental orientation studies. The hatchling behaviour was clearly complicated by beach topography and moon phase. Satellite tracking of post nesting female green and hawksbill turtles from North West Shelf rookeries has identified the Western Australian location of migratory corridors and foraging grounds for these species while Scott Reef turtles migrate from their south Timor Sea rookery to Northern Territory waters. Green turtle nesting on Barrow Island and Sandy Island (Scott Reef) forage at feeding grounds 200 – 1000 km from their nesting beaches. Hawksbill turtles nesting at Varanus Island and Rosemary Islands forage at locations 50 – 450 km from their nesting beaches. While all of the nesting beaches within the B-L-M island complex are protected under the Barrow-Montebello Marine Conservation Reserves, the only foraging ground similarly protected is the Northern Territory foraging ground used by Scott Reef green turtles. None of the foraging grounds used by North West Shelf green or hawksbill turtles is currently protected by conservation reserves.

Smokeless tobacco – snus : critique of usage pattern & influencing factors

Dinh, Van H. January 2012 (has links)
As the global market place becomes more integrated and tensed, there is a shift from thetraditional marketing whereby attention is given solely to the sale of a product to a morecustomer-based marketing. Customer involvement in the processing of a product is thehighlight of this phenomenon. By this their needs and preferences for a product are welladdressed and base on this management can make effective decisions. Customer usagepattern and its influencing factors have become a key for business decision-making.Customer based notion is well known by its effective result in any kind of product. Theycould help businesses to manage, to adjust strategies to better match with the customersexpectations in existing markets. And to enter new markets, where the companies haveno historical databases of the local customers, the Snus usage pattern and its influencingfactors in previous growth markets are helpful to make use of.The motivation of this thesis therefore, is to find out the usage pattern and the influencingfactors of snus (smokeless tobacco) in its growth market such as Sweden and the UnitedStates where until recently gaining popularity. This thesis will make use of relatedtheories, previous studies on snus and behavioral pattern, influencing factors andobservation in Sweden and in the United States. The findings of this thesis and theinfluencing factors on snus usage behavior could be reference guidelines for decisionmakers in the tobacco industry in already existing snus markets and potential markets forthe product in places such as Vietnam and other parts of world. Aside these, the findingswill be helpful in managing tobacco companies in general and snus in particular inexisting markets.

A Critical Analysis of Rural Teachers' Usage of Online Communities

Snider, Sherri A. 01 December 2009 (has links)
The purpose of this study was to analyze data related to rural teachers' use of online communities. Rural teachers are often isolated in their practice and sometimes have difficulty connecting with other teachers with their same assignments or needs due to their professional setting. As Internet availability increases and online communities proliferate, teachers have more opportunity than ever to seek personal and professional support in virtual relationships when face-to-face ones are not easily available. In small schools such as the ones included in this study, teachers can become burned out as they perform the difficult task of teaching with few colleagues in their department or grade level to turn to for support. One interview subject said that she and the only other person with the same teaching assignment don't always have time to communicate and often have to use their lunch period to do so. Another said that she feels very isolated because there are only three of them with the same grade level assignment. The most telling comment came from one high school teacher, "I am the foreign language department." In spite of these expressed feelings of isolation, this study's results do not support widespread use of online communities by these particular rural teachers to help fill their personal and professional needs. The only online communication technology widely used was email. At a minimum, every subject in this study had access to a high-speed Internet connection, functional technology, administrative support, and training. With this type of support already in place, further study is needed to discover what would increase awareness and use of online communities by this group of teachers. Additionally, similar studies in different rural school settings might show different results. Comparisons of study findings between rural schools in different geographic locations would be revealing. Such comparative studies could help inform administrators and online community developers who wish to better meet the needs of rural teachers.
