Chapter 9 examines how algorithms extract knowledge from data. In the 1990s, web sites began to store increasing volumes of data. A new industry grew up to exploit this data for commercial purposes. In a Harvard dorm, Mark Zuckerberg created a web site that allowed students to share personal news. The key to Facebook’s success was an algorithm invented by Zuckerberg to prioritise posts based on their popularity and relevance. The algorithm sparked a revolution in viral messaging. Netflix launched a US$1 million prize to find the most accurate algorithm for recommending movies to based users’ ratings. Google Flu Trends attempted to predict outbreaks of the flu across the USA based on Google queries. Despite initial high profile successes, the project ended in failure - an ode to the limits of data science.

One of the top reasons given for use of the internet is the ability to search for health information. However, much of the planning for web-based health information often fails to consider accessibility issues. If health care organizations and community agencies’ web sites have the latest, most wellresearched information on the health topics of the day, it is useless to those who cannot access it because of invisible technological barriers. Many flashy, high-tech sites were designed only to appeal to the needs of the mainstream population, with no consideration given to how people with disabilities must adapt their use of the web in order to access information. This article addresses issues of access specific to web site development, and will explore barriers to accessibility frequently experienced by web users with disabilities, requirements for ADA compliance, and how people with disabilities use the web. Web site accessibility guidelines, as well as simple evaluation tools, will be discussed. A thorough review of the article will enable even the least tech-savvy of health educators to enhance their skills in planning and evaluating web sites to promote access for people with disabilities.

Purpose – In order to continue to respond to patron needs in a relevant way, it is necessary to continuously reevaluate the central message that the library website is intended to convey. It ' s necessary to question assumptions, listen to user needs, and shift our paradigm to make the library web presence as effective as possible. Design/methodology/approach – This is a regular viewpoint column. A basic literature review was done prior to the column being written. Findings – The library Web site remains, in many respects, the “first face” of the library for patrons. To remain relevant, traditional methodologies used in library science may need to be set aside or catered to the needs of the patron. Originality/value – Various methods regarding design philosophy are explored which may be of use to information professionals responsible for the design and content of the library Web sites.

Purpose – This paper aims to report the findings of an empirical research focusing on Hong Kong online users’ intention to book online tourism products with latest figures. Focusing on the technology acceptance model (TAM), this case study extends the recent research with providing insight regarding the online users’ perceptions of TAM dimensions and how these dimensions are perceived among different demographic groups and Internet usage characteristics with latest figures in Hong Kong, a major tourism destination in Asia with many world-class hotels. Design/methodology/approach – A total of 213 Hong Kong online users were surveyed in March and April 2013 in Hong Kong business districts. Findings – Findings reveal that most respondents who use the Internet for booking online travel products are young, and people above a certain age are not likely to favor booking tourism products online. They are more likely to stick to traditional personal service. Perceived usefulness of the Internet is found more influential than its ease of use in forming a usage intention, and ease of use is perceived more important by jobseekers, student and employees than the other profession groups. In addition, respondents who use the Internet every day and did purchase online tourism product perceived usefulness more important than ease of use. Research limitations/implications – The generalization of this research is limited by its sample size and number of questions. Originality/value – The study gives a new perspective by linking TAM with intention to book online in Hong Kong. The paper would be of interest to the Web site planners or online tourism practitioners to consider Web site usefulness as much as its ease of its use, as both usefulness and ease of use of tourism Web sites are strong predictors of intention to book online.

Click here to listen to the PodcastThe one-third of people who do not gain seizure control through current treatment options need a revolution in epilepsy therapeutics. The general population appears to be showing a fundamental and rapid shift in its opinion regarding cannabis and cannabis-related drugs. It is quite possible that cannabidiol, licensed in the USA for treating rare genetic epilepsies, may open the door for the widespread legalisation of recreational cannabis. It is important that neurologists understand the difference between artisanal cannabidiol products available legally on the high street and the cannabidiol medications that have strong trial evidence. In the UK in 2018 there are multiple high-profile reports of the response of children taking cannabis-derived medication, meaning that neurologists are commonly asked questions about these treatments in clinic. We address what an adult neurologist needs to know now, ahead of the likely licensing of Epidiolex in the UK in 2019.

Internet researchers increasingly have at their disposal of an array of automated software agents, or "bots," which can rapidly and efficiently retrieve a variety of economic and technical data from publicly accessible web sites. While these automated tools greatly facilitate the retrieval and analysis of data for academic research, they may pose ethical problems for Internet researchers. Specifically, automated software bots place some load on servers being accessed, possibly in contradiction to the expected use of such servers, and possibly in violation of the legal prerogatives of web site owners. Determining how and when to access such web sites, and whether to seek the consent of web site owners for retrieval of publicly accessible data presents an apparent conflict between general principles of information policy and the emerging legal precedent regarding trespass to computers. This conflict may be characterized as pitting utilitarian considerations against deontological considerations in a fashion reminiscent of previous debates over informed consent in on-line research. In this paper, we examine both utilitarian and deontological characterizations of the ethical obligations of researchers employing automated data retrieval bots, and argue that the contrasts between the two approaches do not necessarily result in conflict. Instead, we argue that the tension within the relevant practices indicates the need for a "meta-choice" between utilitarian and deontological considerations. We further suggest certain factors that may differentiate such a "metaethical" choice in the context of automated data retrieval from the "meta-ethical" choice presented in previously identified contexts of human subjects research or of web browser technology design. In the end, we argue that by analyzing the ethical issues in terms of the contrast between utilitarian and deontological ethics, it is possible to resolve some of the ethical dilemmas regarding automated data retrieval in fruitful and cogent ways.
