Abstract: Among many other changes, older age is characterized by advanced sleep-wake cycles, changes in the amplitude of various circadian rhythms, as well as reduced entrainment to zeitgebers. These features reveal themselves through early morning awakenings, sleep difficulties at night, and a re-emergence of daytime napping. This review summarizes the observations concerning the biological clock and sleep in the elderly and discusses the documented and theoretical considerations behind these age-related behavioral changes, especially with respect to circadian biology.

Recent studies suggest the determinations of clinical laboratories must be made more precise than at present. This paper presents a means of examining benefits of improvement in precision. To do this we use a mathematical model of the effect upon the diagnostic process of imprecision in measurements and the influence upon these two of Importance of Diagnosis and Prevalence of Disease. The interaction of these effects is grossly non-linear. There is therefore no proper intuitive answer to questions involving these matters. The effects can always, however, be calculated.Including a great many assumptions the modeling suggests that improvements in precision of any determination ought probably to be made in hospital rather than screening laboratories, unless Importance of Diagnosis is extremely high.

SummaryThe theoretical basis for determining the number of antibody sites on antigen molecules is examined. The theoretical considerations are applied to factor VIII molecules. Examples based on data available at the Oxford Haemophilia Centre are calculated to illustrate the approach. It is concluded that there are few sites on each factor VIII molecule for human antibody. The three antibodies for which reasonable data were available suggest 1–3 sites for human antibody. The data for rabbit antibody suggest 5–6 sites per factor VIII molecule.

This paper offers a few remarks on the so-called heterodoxy commentaries of recent times (e.g. Bod 2013, Csaba 2011). In accordance with the growing popularity of unusual economic policy actions, a set of “tools” is emerging that aims to exert its effects breaking with instrumental actions. Outlining a special framework of the history of mainstream economics, it will be argued that economic policy only gradually has become capable of applying this system. In our view, both the emergence of symbolic economic policies mentioned above and the rise of heterodoxy are on the same level, since certain governments can only operate through giving signals. Although it is not the time to formulate ultimate and eternal generalised statements, it may perhaps be stated that symbolic economic policies can make some room for manoeuvring available as a last resort. In other words, the possibility of a certain kind of economic policy “tools” can be derived from theoretical considerations, and this set has become highlighted recently by some constraining changes in the macroeconomic environment. Our theoretical framework will be filled sporadically with some episodes from the last few years of the economic policy of Hungary.
