An Attempt to Improve Decision Confidence in Regret-Based Decision-Makers

For some individuals, daily decisions are a struggle because they worry about the regret they will feel if they make a poor choice. This regret-based decision style is associated with lower decision confidence, lower general self-efficacy and lower optimism, and greater decisional self-doubt. This study sought to improve these individuals’ decision confidence by selecting those with a slight tendency toward either an analytical or an intuitive decision-style and reinforcing this existing tendency. This intervention was predicted to increase their confidence because endorsing either style correlates positively with self-efficacy and optimism, and negatively with decisional self-doubt. Fifty-eight regret-based individuals with slight analytical or intuitive tendencies, or both (“flexible” decision-makers) were selected using The Decision-Making Styles Inventory. Individuals from each of the 3 decision-style groups were randomly assigned to manipulation or control conditions. Subjects completed General Self-Efficacy and Optimism measures. Then the 3 manipulation groups were informed of their decision-making tendencies, and the benefits of their particular styles, while control groups were simply told that people use various decision styles. Next subjects responded to decision scenarios, rating decision confidence and difficulty for each, and then completed the self-efficacy and optimism measures again. The only statistically significant result was that the manipulation group had lower decision confidence. Overall, the manipulation did not produce the predicted results. If the results had been as predicted, this intervention would have provided support for a relatively simple way to increase decision confidence in those who worry about experiencing decisional regret.No embargoAcademic Major: Psycholog

SCIENTIFIC AND NATURE PROTECTION SIGNIFICANCE OF MODEL SITUATIONS IN THE DEVELOPMENT OF ECOSYSTEMS

Model situations that arise due to disturbances of the structure of the living cover and dynamics of ecosystem succession, are often unique ecological experiments. The author examines the value of model situations for research and conservation. Taking into account their specific nature, an addition to the existing environmental protection categories system is offered

Variation in Microbiome Composition and Stability for a Vancomycin Treated Primary Sclerosing Cholangitis Patient with Ulcerative Colitis Compared with Controls

The bacterial composition of the human intestines contributes to much more than just digestion. In the inflammatory, autoimmune conditions primary sclerosing cholangitis (PSC) and ulcerative colitis (UC), the microbiome may be, in some cases, a factor. To gain a better understanding of the composition and stability of the microbiome in a patient treated with vancomycin for PSC, terminal restriction fragment (TRF) analysis was performed on 13 controls and 1 patient, and 16s rRNA microbiome composition analysis was performed on 1 patient and 3 controls. Results showed similar levels of stability, with surprising differences in composition

Dual-Purpose Ro-Ro Fast Ship: Some Comments and Lower Cost Option

The article discusses an alternative variant to the high-speed trimaran designed as a rollon/roll-off ship for commercial or military use that was recently published in literature (Marine Technology 42(2005)3). Initial ship performance and general plan are discussed. The alternative option to the initial ship is given with a new cargo deck arrangement for unloading time minimisation. It is shown that the proposed option with the same payload, main engine power, same speed as a minimum, and with a smaller full displacement is cheaper for building, but can ensure the same income

On Small-Size Motor Yachts with Round-Bilge Hulls

In this paper multi-hull small-sized motor yachts with rounded bilge hulls were examined as alternative options for enough high speed: catamarans without and with under-water foils, as well as outriggered boats without and with foils. Besides, a twin-hull motor yacht with decreased water-plane area was examined too. Restriction of speed, as a result of avoiding hard chine, was examined; necessary power and seakeeping levels of the examined yachts were estimated too. It has shown that the examined yachts are compatible (from the energy point of view) with today’s dominant planing monohulls for defi ned ranges of speed; the examined multi-hulls are better from the seakeeping point of view than the comparable monohulls
