We review the current status and future prospects of the PLANET collaboration, an international team of astronomers performing high-precision photometric monitoring of microlensing events. Our photometric precision and sampling is characterised and the suitability of the database for variable star studies is discussed. Preliminary results on K-giant stability are presented.
38 hypertensive Canadian steelworkers who were neither compliant with medications nor at goal diastolic blood-pressure six months after starting treatment were allocated either to a control group or to an experimental group who were taught how to measure their own blood-pressures, asked to chart their home blood-pressures and pill taking, and taught how to tailor pill taking to their daily habits and rituals; these men were also seen fortnightly by a high-school graduate with no formal health professional training who reinforced the experimental manoeuvres and rewarded improvements in compliance and blood-pressure. Six months later, average compliance had fallen by 1.5% in the control group but rose 21.3% in the experimental group. Blood-pressures fell in 17 of 20 experimental patients (to goal in 6) and in 10 of 18 control patients (to goal in 2).
The potential benefit of vigorous medical treatment for hypertension often remains out of reach, in part because the patient does not comply with treatment. We believe that this non-compliance is a major barrier to the effective control of hypertension and that our understanding of this phenomenon is primitive. In phase I of a trial of strategies for improving compliance we found that neither the mastery of facts about hypertension nor receiving care and follow-up at work in “company time” led to any improvement. We describe here the second phase of this trial in which the application of more behaviourally oriented strategies did lead to improvements in both compliance and blood-pressure control.
These have been described in detail elsewhere. Briefly, the examination of 5400 men at Dominion Foundries and Steel Company (over 95% of a random two-thirds sample of male employees) yielded 245 who had high blood-pressures (when sitting quietly on three separate days, a standard series of fifth-phase diastolic blood-pressure were ≥95 mm Hg), were free of remediable forms of hypertension, were taking no daily medications (70 men were on treatment and were therefore excluded), and had not been treated for hypertension in the preceding six months.
In phase I of this trial, men were randomly allocated into a factorial design in order to test strategies affecting either the convenience of their follow-up care or their knowledge about hypertension and its treatment.
New excavations were undertaken at Palaikastro in 1986 in the fields lying between the previous excavations and the sea. The remains of two structures and a roadway were found. Building 1 is a monumental structure, constructed in LM IA, that seems to have been destroyed in LM IB, and probably reoccupied and destroyed/abandoned in LM IIIA2. Over the top of Building 1 a less impressive structure was built and occupied then abandoned in LM IIIB. The second structure has many features in common with Late Minoan cult buildings. Building 2 is a typical LM town house of the wealthier variety, destroyed in LM IA with traces of later reoccupation in ?LM III. The roadway, called ‘Harbour Road’, seems to lead from the likely location of the Minoan harbour to the entrance of Building 1.
In Part I, a survey of the Minoan town at Palaikastro recording architectural features and sherd densities is presented. The survey allows for the town limits to be drawn and the probable location of the town centre to be identified. Possible approach routes are noted and an extension of the town to the Promontory and East Beach areas is examined. Part II is a report on building materials at Palaikastro and the Minoan quarries at Ta Skaria, where large quantities of calcareous sandstone were extracted. A magnetic survey of the central, unexcavated part of the site is presented in Part III. A short report on ancient remains at Kouremonos is given in Part IV. Part V is a summary of the previous parts, pointing out important results such as the evidence for ribbon development along approach routes in MM III/LM I and the likelihood that almost 1,000 cubic metres of calcareous sandstone used in ashlar masonry were extracted from the Minoan quarries but remain unaccounted for at Palaikastro. An appendix describes in full two deposits disturbed by ploughing.
