Comentários online nos websites de comparação de hotéis

Com o rápido aumento da utilização da internet no mundo, os consumidores utilizam cada vez mais os websites para comparação, compra e venda de produtos. Atualmente os utilizadores da internet deixaram de procurar exclusivamente informação e tornaram-se eles próprios fornecedores de experiências através de comunidades online, que continuam em grande crescimento. Seguindo essa tendência, muitas indústrias escolheram a internet como canal de comunicação preferido e a indústria hoteleira não foge à regra. Assim a presente dissertação resulta numa pesquisa, em que o principal objetivo é entender de que forma os diversos fatores de informação presentes nos comentários online realizados nos websites de comparação de hotéis influenciam a utilização da informação pelo consumidor. Na presente metodologia é utilizado o modelo de Filieri e McLeay (2014), o tipo de inquérito utilizado é um questionário online para analisar quais os fatores que mais influenciam os consumidores a utilizarem a informação disponível nos comentários online. Os principais resultados obtidos neste estudo indicam que a precisão da informação, a consistência da informação e o ranking do alojamento influenciam a utilização da informação presente nos comentários online.

I know what you did this summer: Users' behavior on internet

Human age is surrounded by assumed set of rules and behaviors imposed by local culture and the society they live in. This paper introduces software that counts the presence of a person on the Internet and examines the activities he/she conducts online. The paper answers questions such as how "old" are you on the Internet? How soon will a newbie be exposed to adult websites? How long will it take for a new Internet user to know about social networking sites? And how many years a user has to surf online to celebrate his/her first "birthday" of Internet presence? Paper findings from a database of 105 school and university students containing their every click of first 24 hours of Internet usage are presented. The findings provide valuable insights for Internet Marketing, ethics, Internet business and the mapping of Internet life with real life. Privacy and ethical issues related to the study have been discussed at the end. © Springer Science+Business Media B.V. 2010.

Internet video telephony allows speech reading by deaf individuals and improves speech perception by cochlear implant users

OBJECTIVE To analyze speech reading through Internet video calls by profoundly hearing-impaired individuals and cochlear implant (CI) users. METHODS Speech reading skills of 14 deaf adults and 21 CI users were assessed using the Hochmair Schulz Moser (HSM) sentence test. We presented video simulations using different video resolutions (1280 × 720, 640 × 480, 320 × 240, 160 × 120 px), frame rates (30, 20, 10, 7, 5 frames per second (fps)), speech velocities (three different speakers), webcameras (Logitech Pro9000, C600 and C500) and image/sound delays (0-500 ms). All video simulations were presented with and without sound and in two screen sizes. Additionally, scores for live Skype™ video connection and live face-to-face communication were assessed. RESULTS Higher frame rate (>7 fps), higher camera resolution (>640 × 480 px) and shorter picture/sound delay (<100 ms) were associated with increased speech perception scores. Scores were strongly dependent on the speaker but were not influenced by physical properties of the camera optics or the full screen mode. There is a significant median gain of +8.5%pts (p = 0.009) in speech perception for all 21 CI-users if visual cues are additionally shown. CI users with poor open set speech perception scores (n = 11) showed the greatest benefit under combined audio-visual presentation (median speech perception +11.8%pts, p = 0.032). CONCLUSION Webcameras have the potential to improve telecommunication of hearing-impaired individuals.

Internet financial reporting in Saudi Arabia: users' perceptions and disclosures

This thesis investigates corporate financial disclosure practices on Web sites and their impact. This is done, first by examining the views of various Saudi user groups (institutional investors, financial analysts and private investors) on disclosure of financial reporting on the Internet and assessing differences, if any, in perceptions of the groups. Over 303 individuals from three groups responded to a questionnaire. Views were elicited regarding: users attitude to the Internet infrastructure in Saudi Arabia, users information sources about companies in Saudi Arabia, respondents perception about the advantages and disadvantages in Internet financial reporting (IFR), respondents attitude to the quality of IFR provided by Saudi public companies and the impact of IFR on users information needs. Overall, it was found professional groups (Institutional investors, financial analysts) hold similar views in relation to many issues, while the opinions of private investors differ considerably. Second, the thesis examines the use of the Internet for the disclosure of financial and investor-related information by Saudi public companies (113 companies) and look to identify reasons for the differences in the online disclosure practices of companies by testing the association between eight firm-specific factors and the level of online disclosure. The financial disclosure index (167 items) is used to measure public company disclosure in Saudi Arabia. The descriptive part of the study reveals that 95 (84%) of the Saudi public companies in the sample had a website and 51 (45%) had a financial information section of some description. Furthermore, none of the sample companies provided 100% of the 167 index items applicable to the company. Results of multivariate analysis show that firm size and stock market listing are significant explanatory variables for the amount of information disclosed on corporate Web sites. The thesis finds a significant and negative relationship between the proportion of institutional ownership of a companys shares and the level of IFR.

Bringing the internet down to earth : emerging spaces of locative media

Web 1.0 referred to the early, read-only internet; Web 2.0 refers to the ‘read-write web’ in which users actively contribute to as well as consume online content; Web 3.0 is now being used to refer to the convergence of mobile and Web 2.0 technologies and applications. One of the most important developments in mobile 3.0 is geography: with many mobile phones now equipped with GPS, mobiles promise to “bring the internet down to earth” through geographically-aware, or locative media. The internet was earlier heralded as “the death of geography” with predictions that with anyone able to access information from anywhere, geography would no longer matter. But mobiles are disproving this. GPS allows the location of the user to be pinpointed, and the mobile internet allows the user to access locally-relevant information, or to upload content which is geotagged to the specific location. It also allows locally-specific content to be sent to the user when the user enters a specific space. Location-based services are one of the fastest-growing segments of the mobile internet market: the 2008 AIMIA report indicates that user access of local maps increased by 347% over the previous 12 months, and restaurant guides/reviews increased by 174%. The central tenet of cultural geography is that places are culturally-constructed, comprised of the physical space itself, culturally-inflected perceptions of that space, and people’s experiences of the space (LeFebvre 1991). This paper takes a cultural geographical approach to locative media, anatomising the various spaces which have emerged through locative media, or “the geoweb” (Lake 2004). The geoweb is such a new concept that to date, critical discourse has treated it as a somewhat homogenous spatial formation. In order to counter this, and in order to demonstrate the dynamic complexity of the emerging spaces of the geoweb, the paper provides a topography of different types of locative media space: including the personal/aesthetic in which individual users geotag specific physical sites with their own content and meanings; the commercial, like the billboards which speak to individuals as they pass in Minority Report; and the social, in which one’s location is defined by the proximity of friends rather than by geography.

Framework for the long-term operation of a mobile robot via the Internet

This paper describes an autonomous docking system and web interface that allows long-term unaided use of a sophisticated robot by untrained web users. These systems have been applied to the biologically inspired RatSLAM system as a foundation for testing both its long-term stability and its practicality. While docking and web interface systems already exist, this system allows for a significantly larger margin of error in docking accuracy due to the mechanical design, thereby increasing robustness against navigational errors. Also a standard vision sensor is used for both long-range and short-range docking, compared to the many systems that require both omni-directional cameras and high resolution Laser range finders for navigation. The web interface has been designed to accommodate the significant delays experienced on the Internet, and to facilitate the non- Cartesian operation of the RatSLAM system.

Refiguring the net generation : beyond users

In place of, or alongside paradigms such as "the net generation", we suggest that the full implications of the Internet might be productively analysed using a broader framework, that of social imaginaries. First used by Cornelius Castoriadis and more recently by Charles Taylor, the social imaginary, as applied here, is the loosely co-ordinated body of significations that enable our social acts and practices by making sense of them.

An investigation into how the imagining of the nation is affected by understandings of the Internet

My research is located in an abiding concern with the nation and takes a special interest in the predictions and expectations surrounding the impact of the Internet on how this institution is lived. It is my hypothesis that the effects of the Internet are not limited only to those who are users but extends even to those who may never have witnessed its workings. The research question I began with: how is the imagining of the nation affected by our understandings and expectations of the Internet, developed through the writing of the first three chapters to: how is the living of the nation affected by the Internet’s inflection on lived time and lived space?

Older Australians and the Internet

In late 2009, Sandra Haukka secured funding from the auDA Foundation to explore what older Australians who never or rarely use the Internet (referred to as ‘non-users’) know about the types of online products and services available to them, and how they might use these products and services to improve their daily life. This project aims to support current and future strategies and initiatives by: 1) exploring the extent to which non-users are aware of the types and benefits of online products and services, (such as e-shopping, e-banking, e-health, social networking, and general browsing and research) as well as their interest in them b) identifying how the Internet can improve the daily life of older Australians c) reviewing the effectiveness of support and services designed to educate and encourage older people to engage with the Internet d) recommending strategies that aim to raise non-user awareness of current and emerging online products and services, and provide non-users with the skills and knowledge needed to use those products and services that they believe can improve their daily life. The Productive Ageing Centre at National Seniors Australia, and Professor Trevor Barr from Swinburne University provided the project with in-kind support.

The future of the internet economy : addressing challenges facing the implementation of the Australian national broadband network

Innovation is vital for the future of Australia.s internet economy. Innovations rely on businesses. ability to innovate. Businesses. ability to innovate relies on their employees. The more these individual end users engage in the internet economy, the better businesses. engagement will be. The less these individual end users engage, the less likely a business is to engage and innovate. This means, for the internet economy to function at its fullest potential, it is essential that individual Australians have the capacity to engage with it and participate in it. The Australian federal government is working to facilitate the internet economy through policies, legislation and practices that implement high-speed broadband. The National Broadband Network will be a vital tool for Australia.s internet economy. Its .chief importance¡® is that it will provide faster internet access speeds that will facilitate access to internet services and content. However, an appropriate infrastructure and internet speed is only part of the picture. As the Organisation for Economic Co-operation and Development identified, appropriate government policies are also needed to ensure that vital services are more accessible by consumers. The thesis identifies essential theories and principles underpinning the internet economy and from which the concept of connectedness is developed. Connectedness is defined as the ability of end users to connect with internet content and services, other individuals and organisations, and government. That is, their ability to operate in the internet economy. The NBN will be vital in ensuring connectedness into the future. What is not currently addressed by existing access regimes is how to facilitate end user access capacity and participation. The thesis concludes by making recommendations to the federal government as to what the governing principles of the Australian internet economy should include in order to enable individual end user access capacity.

Convenience, loyal, and customising users : a survey of the behaviours and intentions of young online news users in Australia

The implications of the shift to online news consumption for journalism cultures and practices have attracted considerable scholarly attention and public debate. Less well considered are the implications of online news consumption for and by young people. This paper reports on research into the behaviours and intentions of online news consumers, 18-30 years of age, to propose three distinctive types of user (convenience, loyal and customising). Also opened up for discussion are questions about the strategic value to commercial news organisations of audience-centred empirical research that seeks to respond the crisis of professional journalism.

Acceptability of cognitive-behaviour therapy via the Internet for cessation of benzodiazepine use

Introduction and Aims: Long-term use of benzodiazepines remains common, and conveys significant risk. Providing psychological intervention in association with gradual dose reduction increases cessation rates above dose reduction alone, but appropriate psychological support is difficult to obtain. This study was undertaken to assess the outcomes of an uncontrolled case series of an internet-based cognitive-behaviour therapy (I-CBT) for benzodiazepine cessation. Design and Method: Users of benzodiazepines for > 3 months who wanted to reduce or cease benzodiazepines participated in the trial. They completed online assessments and accessed 13 newsletters on managing withdrawal symptoms and developing alternate ways to cope with life events. Therapist assistance was provided by email. Follow-up was at 3 and 6 months and feedback was obtained via comments and emails. Results: Program ratings and emailed comments of the program were positive. Thirty-two people registered for the program and 14 (44%) completed a 6-month follow-up. Of these, 8 (57%) reduced weekly intake by at least half, including 5 (36%) who ceased use. Shorter duration of use and birth outside Australia predicted greater percentage reductions at 3 months, while being partnered and in paid employment predicted reductions at 6 months. Discussion and Conclusion: While results were encouraging, controlled research is required to confirm the efficacy of the program, and engagement of both users and prescribers needs further attention.

Grounding the internet : categorising the geographies of locative media

Taxonometrical uncertainty is prevalent in the field of locative media, which has been variously referred to as “the geomobile web” (Crawford and Goggin, 2009), “the geoweb” (Lake et al., 2004), “Where 2.0” (O’Reilly, 2008:1), and “DigiPlace” (Zook and Graham, 2007). However, it is not only the rapid development of the technology, or the various academic disciplinary approaches to it, that have resulted in this uncertainty but also the deeply ideological debates and concerns about what locative media should and should not be. The intention of this article is to provide an overview of existing literature and research in this field in order to develop a synthetic overview of the various types of locative media, and the geographies arising from them. Not only will such taxonomy clarify communication about locative media, it will identify for developers, users, policy-makers and scholars the specific contours and affordances of the different types of locative media, as well as the issues associated with them.

The continuing relevance of the library as a third place for users and non-users of IT : the case of Canada Bay

The purpose of this paper is to consider how libraries support the development of community networks both physically and digitally. To do this, a case-study methodology was employed, including a combination of data about the library and qualitative interviews with library users considering their experience of the library. This paper proposes that libraries act as ‘third places’ spatially connecting people; libraries also build links with online media and play a critical role in inclusively connecting non-technology users with the information on the Internet and digital technology more generally. The paper establishes the value of libraries in the digital age and recommends that libraries actively seek ways to develop links between non-technology users and activity on the Internet. It addresses the need to reach these types of non-technology users in different ways. Further, it suggests that libraries utilise their positioning as third places to create broader community networks, to support local communities beyond existing users and beyond the library precinct.
