King Sound in northwestern Australia, with a tropical semi-arid climate is situated in a macrotidal tide-dominated regime. The shores of King Sound are bordered by tidal flats that exhibit a considerable variation in geomorphology and stratigraphy. Erosion is the dominant geomorphic process forming the tidal flats today. Three types of Chaussure Nike Blazer Noir erosion are important; these are sheet, cliff and tidal-creek erosion. Tidal-flat geomorphology at the local scale is an expression of which erosion type is dominant. The geomorphology at regional scale is largely an expression of the extent that erosion has gone to completion in removing Holocene, Pleistocene and bedrock stratigraphic units.
Determination of erosion rates over the past few decades, extrapolation of these rates into the past, together with stratigraphic and diagenetic data point to a long-term erosional history for King Sound, King Sound itself appears to be formed Acheter Blazer Homme largely as a result of long-term lateral erosion.
When the assignment of incentives is uncertain, we study how the regularity and frequency of rewards and risk attitudes influence participation and effort. We contrast three incentive schemes in a real-effort experiment in which individuals decide when to quit: a continuous incentive scheme and two intermittent ones, fixed and random. In all treatments, we introduce a regime shift by withdrawing monetary rewards after the same unknown number of periods. In such an ambiguous environment, we show that less able and more risk averse players are less persistent in effort. Intermittent incentives lead to a greater persistence of effort, Chaussures Nike Blazer Femme Pas Cher while continuous incentives entail exit as soon as payment stops. Randomness increases both earlier and later exiting. This selection effect in terms of ability and risk attitudes combined with the impact of intermittent rewards on persistence lead to an increase in mean performance after the regime shift when incentives are intermittent.
