Accessibility statement for James Cheney's University of Edinburgh home page

This accessibility statement applies to James Cheney's University of Edinburgh homepage.

This website is run by James Cheney, an employee of the University of Edinburgh. This website collects information about my research interests and other activities which are aimed at other people interested in my research or in working with me. I want as many people as possible to be able to use this website. For example, that means you should be able to:

  • change colours, contrast levels and fonts
  • zoom in up to 300% without the text spilling off the screen
  • navigate most of the website using just a keyboard
  • navigate most of the website using speech recognition software
  • listen to most of the website using a screen reader (including the most recent versions of JAWS, NVDA and VoiceOver)

I've also made the website text as simple as possible to understand.

How accessible this website is

I know some parts of this website are not fully accessible in the following way:

  • most older PDF documents are not fully accessible to screen reader software
  • you may not be able to skip to the main content when using a screen reader

Feedback and contact information

I’ll consider your request and get back to you in 30 days. I may not be able to personally accommodate requests to convert material on my web page, into other formats but I'll do my best to accommodate such requests.

Reporting accessibility problems with this website

I'm always looking to improve the accessibility of this website. If you find any problems not listed on this page or think I'm not meeting accessibility requirements, contact:

Enforcement procedure

The Equality and Human Rights Commission (EHRC) is responsible for enforcing the Public Sector Bodies (Websites and Mobile Applications) (No. 2) Accessibility Regulations 2018 (the ‘accessibility regulations’). If you’re not happy with how I respond to your complaint, contact the Equality Advisory and Support Service (EASS).

Contacting us by phone or visiting us in person

I am not able to personally accommodate in person visits or provide text relay or induction loop services to provide information from my web page. However, for any requests for information in these ways from the university generally, please see the generic University accessibility statement available from any main University web page.

Technical information about this website’s accessibility

The University of Edinburgh is committed to making its website accessible, in accordance with the Public Sector Bodies (Websites and Mobile Applications) (No. 2) Accessibility Regulations 2018.

Compliance status

This website is partially compliant with the Web Content Accessibility Guidelines version 2.1 AA standard, due to the exemptions listed below.

Non-accessible content

The content listed below is non-accessible for the following reasons.

Non-compliance with the accessibility regulations


Disproportionate burden

Although mostly the web pages on this site are written using navigable HTML, the layout was defined using HTML tables which is deprecated. I assessed the amount of work needed to revise the web pages that work this way and believe it constitutes a disproportionate burden within the meaning of the regulation. I will remedy this next time I redesign the web pages, using an approach that is accessible and easier to maintain.

Content that’s not within the scope of the accessibility regulations

PDFs and other documents

This site hosts PDFs that are author copies of papers and other documents connected to my research. They are not essential to the University providing its services; in most cases the documents are available from other places such as the publishers of research articles, and in most cases I also include links to the published versions. These documents typically make use of mathematical typesetting techniques that are probably even less accessible than PDFs generally.

The accessibility regulations do not require us to fix PDFs or other documents published before 23 September 2018 if they’re not essential to providing our services. Most PDFs published on this web page are exempt for this reason. Any new PDFs that provide any information essential to the University's services will meet accessibility standards (and most likely be hosted on a central content management system). PDFs such as preprints or author copies of publications may continue to be hosted on this page, but will always be accompanied by a link to the official published version; the publisher should be contacted in order to arrange for an accessible version of the work.

Preparation of this accessibility statement
