Objective This pilot study assessed the feasibility, efficacy and safety of an individual dose‐titration approach, intravenous ( IV ), intramuscular IM ) subcutaneous SC routes for treating depression with ketamine. Method Fifteen treatment‐refractory depressed participants received ketamine or midazolam (control treatment) in a multiple crossover, double‐blind study. Ketamine was administered by n = 4), 5) 6) injection. Dose titration commenced at 0.1 mg/kg, increasing mg/kg up to 0.5 given...
The visual appearance of a Web page influences the way user will interact with page. structural elements (such as text, tables, links, and images) their characteristics colour size) are used to determine presentation complexity level We theorise that by understanding user's aesthetic perception we can understand cognitive effort required for interaction This paper describes an investigation into pages. Results show strong high correlation between users' complexity, (links, images, words...
Objectives. Research studies have reported impressive antidepressant effects with ketamine but significant knowledge gaps remain over the best method of administering ketamine, and relationships between dose, response adverse effects. Methods. In this pilot dose-finding study, efficacy tolerability given by rapid intravenous (i.v.) infusion were assessed in a double-blind, placebo-controlled, crossover design, four subjects treatment- resistant depression. Each subject received up to i.v....
The visual complexity of Web pages is much talked about; “complex are difficult to use,” but often regarded as a subjective decision by the user. This limited use if we wish understand importance complexity, what it means, and how can be used. We theorize that understanding user's perception page cognitive effort required for interaction with page. important because using an easily identifiable measure, such implicit marker load, design which easier interact with. have devised initial...
The equality of access – accessibility is difficult to quantify, define, or agree upon. Our previous work analysed the responses web specialists in regard a number pre-defined definitions accessibility. While uncovering much, this analysis did not allow us quantify communities' understanding relationship has with other domains and assess how community scopes In case, we asked over 300 people, an interest accessibility, answer 33 questions surrounding between user experience (UX), usability;...
Eye tracking has commonly been used to investigate how users interact with web pages, the goal of improving their usability. This article comprehensively revisits techniques that could be applicable eye data for analysing user scanpaths on pages. It also uses a third-party study compare these techniques. allows researchers recognise existing goals, understand they work and know strengths limitations so can make an efficient choice studies. These mainly calculating...
Web accessibility means that disabled people can effectively perceive, understand, navigate, and interact with the web. evaluation methods are needed to validate of web pages. However, role subjectivity expertise in such is unknown has not previously been studied. This article investigates effect by conducting a Barrier Walkthrough (BW) study 19 expert 57 nonexpert judges. The BW method an be used manually assess pages for different user groups as motor impaired, low vision, blind, mobile...
Eye tracking studies have widely been used in improving the design and usability of web pages research understanding how users navigate them. However, there is limited clustering users’ eye movement sequences (i.e., scanpaths) on to identify a general direction they follow. Existing tends be reductionist, which means that resulting path so short it not useful. Moreover, little work correlating scanpaths with visual elements underlying source code, result cannot for further processing. In...
Anecdotal evidence suggests that people with autism may have different processing strategies when accessing the web. However, limited empirical is available to support this. This paper presents an eye tracking study 18 participants high-functioning and neurotypical investigate similarities differences between these two groups in terms of how they search for information within web pages. According our analysis, are likely be less successful completing their searching tasks. They also a...
Currently, the vast majority of web sites do not support accessibility for visually impaired users. Usually, these users have to rely on screen readers: applications that sequentially read content a page in audio. Unfortunately, readers are able detect meaning different objects, and thus implicit semantic knowledge conveyed presentation is lost. One approach described literature tackle this problem, Dante approach, which allows annotation pages provide with extra (semantic) better facilitate...
The importance of the World Wide Web for information dissemination is indisputable. However, dominance visual design on leaves visually disabled people at a disadvantage. Although assistive technologies, such as screen readers, usually provide basic access to information, richness experience still often lost. In particular, traversing becomes complicated task since objects presented their sighted counterparts are neither appropriate nor accessible users. To address this problem, we have...
Access is what the web 'about', it motivation behind its creation, and rationale HTML. The desire to provide all users at CERN with ability access documents was Tim Berners-Lee's primary goal, this goal must also be carried through equal for users. But equality of -- accessibility difficult quantify, define, or agree upon. In a constantly evolving field, understanding each other can tricky; indeed, there are many different definitions in literature, perspective. This makes our community...
Web Content Accessibility Guidelines 2.0 (WCAG 2.0) require that success criteria be tested by human inspection. Further, testability of WCAG is achieved if 80% knowledgeable inspectors agree the has been met or not. In this paper we investigate very core 2.0, being their ability to determine web content accessibility conformance. We conducted an empirical study ascertain when experts and non-experts evaluated four relatively complex pages; differences between two. discuss validity...
