Over Time

Three techniques for assessing extension of one's personal future (line-marking, open-ended report, life-events) were compared in a sample of 74 respondents. Two points of data collection were employed to examine short-term stability. At both administrations, correlations among indices suggested that techniques were only moderately comparable. Short-term stabilities were variable; correlations ranged from .42 to .79. Across subgroups of the sample, the direct, open-ended report of extension showed the greatest stability, while life-event extension showed the least. Apparently, extension of thinking about the future should be assessed by more than one technique to investigate potential relationships with other variables or changes over time in perspective about the future.

The Given

In order to set up a successful mammography screening program in the Republic of Srpska, a Siemens Mammomat 1000 X-ray machine was selected for analysis as the said mammography system is widely used in clinical practice. The variations in tube parameters (specific air kerma, high-voltage accuracy and reproducibility, linearity between exposure and dose exposure time) were monitored over a five-year period, from 2008 to 2012. In addition, due to observed daily fluctuations for chosen parameters, a series of measurements were performed three times a day within a single-month period (mainly October 2012). The goal of such an experimental set up is to assess short-term and long-term stability of tube parameters in the given mammography unit and to make a comparison between them. The present paper shows how an early detection of significant parameter fluctuations can help eliminate irregularities and optimize the performance of mammography systems.
