The clusters can be displayed and explored using three visualisations: Sammon cluster view, Dendro map or radial interactive visualization. This link, VISHNU, will open the application in a new browser. Papers M Carey, D Heesch and S Rüger: Info Navigator: A visualization tool for document searching and browsing.

Time to Act Over the Corruption That is Killing Ethical Journalism - Ethical Journalism Network The world of journalism is full of good intentions but the idea of news media as a cornerstone of democracy and ethical values is fast disappearing according to a report released today by the Ethical Journalism Network. The report, Untold Stories: How Corruption and Conflicts of Interest Stalk the Newsroom, covers 18 countries and exposes how financially-stricken news media are being overwhelmed by political and corporate forces. The report finds that in countries both rich and poor, there are ‘dark arts’ at work in newsrooms: media managers are doing deals with advertisers to carry paid-for material disguised as honest news; reporters and editors accept bribes and irregular payments; and a culture of dependence on political and corporate friends makes it increasingly difficult to separate journalism from propaganda and impartial reporting from public relations. Today that balance of power has shifted. The story everywhere is one of an uphill struggle. Click here to download the report.

Center for Implementing Technology in Education (CITEd) What Should I do? Noah - ADHD: Attention Deficit Hyperactivity Disorder Question: Ok so where to begin? I’m a 20 year old college student, and I’m wondering what to do. I was diagnosed with ADHD when I was in elementary school, prescribed medicine and took it for years. I finally got sick of being on meds and stopped. I havent been on the medicine for some years now, but I’ve just recently started looking back on my performances in the past year or so. This Disclaimer applies to the Answer Below Dr. Answer: One of the many problems with ADHD is the fact that people do not seem to be aware that medicine alone cannot help those with this disorder. So, what I suggest is that you find the psychologists who are expert in ADHD and who can work with you. When I say that this is an ongoing process, what I mean is that there is no "cure" for ADHD but people can and do learn to cope with it. I am interested that you say that you are creative. Definitely stop using pot as that will only make things worse. Good Luck More "Ask Dr.

Adult Attention-Deficit/Hyperactivity Disorder: A Diagnostics Challenge and Treatment Dilemma Adult attention-deficit/hyperactivity disorder (ADHD) has always been a difficult-to-diagnose disorder for clinicians. This is mostly due to the lack of authentic diagnostic tools for adults, as well as because the Diagnostic and Statistical Manual of Mental Disorders, fifth edition,1 criteria for an ADHD diagnosis require evidence of symptoms present before age 12 years, which is not always known. Although ADHD symptoms were described more than 100 years ago in children, it is only in recent times that the adult form has received appropriate clinical attention; there are now medications approved by the US Food and Drug Administration to treat adult ADHD. In summary, diagnosis of adult ADHD requires a careful history, particularly evidence of social and academic difficulties during childhood. This issue of Psychiatric Annals discusses how to properly diagnose ADHD in adults, as it is truly an ethical dilemma and a diagnostic challenge for many clinicians. References
