We examine critically the claims made by Fredrickson and Losada (2005) concerning the construct known as the "positivity ratio." We find no theoretical or empirical justification for the use of differential equations drawn from fluid dynamics, a subfield of physics, to describe changes in human emotions over time; furthermore, we demonstrate that the purported application of these equations con...

Conventional synthetic DMARD (csDMARD) therapy in patients with axial spondyloarthritis (SpA) is a matter of continuous debate. Part of this discussion is a dispute about methotrexate (MTX) comedication in patients with axial SpA treated with tumour necrosis factor inhibitors biologicals (TNFi). The dispute seems to be based on perceptions rather than scientific evidence and may have been fuell...

s m a p q c c want to share some information on the problem of schemic heart disease in women. Because of a focus on en, this topic has received inadequate attention, and the eneral assumption has been that what is true for men is also rue for women. In this overview, I will try to separate the acts from the wishful thinking that has evolved on this opic, largely due to deficiencies in our know...

The current fascination with electronic medical records (EMRs) is not new. For decades, vendors have capitalized on this enthusiasm. But hospitals and clinics have ended up with little to show for their large outlays. Indeed, computing at a typical hospital has not gotten much beyond what was available twenty-five years ago. The RAND analysis continues the tradition of hope and hype. Unfortunat...

Tamper detection 2 has an important role to play in domestic nuclear security and safeguards, as well as in international verification and treaty monitoring. Unfortunately, ideas about tamper detection often seem to be based on misconceptions, fuzzy goals, and wishful thinking. Current tamper detection programs are hampered by these problems, as well as by poor training, limited analysis, vague...

Rational-choice theory tries to explain behaviour on the assumption that individuals optimize. Some forms of irrational behaviour can be explained by assuming that the individual is subject to hedonic, pleasure-seeking mechanisms, such as wishful thinking or adaptive preference formation. In this paper, I draw attention to psychic mechanisms, originating in the individual, which make her worse ...

Much has been made of the shifting relationships of power caused by the forces of globalization. Through the intensification of social interconnections, we now can apprehend the world as a single place, aware of our own place and its relative location within the range of world experience. The media of communication are key players in this process, both as causes and outcomes. Like with other ar...

Regretfully, this paper provides more questions than answers. Its main issue is how to balance the enthusiasm of the general public for web tools (wikies, blogs etc.) to provide content with the "authority" of the established content-providing (and content-preserving) institutions (i.e., universities, libraries, museums), in order to get the best possible worldwide resources. The central proble...
