This study constructs a panel threshold regression model to explore the price impact of foreign institutional herding of firms listed in the Taiwan Stock Exchange during January 2000 to June 2008. Our panel threshold model is constructed to explore the price impact of foreign institutional investors’ herding in the Taiwan stock market after controlling the firm size. By examining the presence o...

It is common in econometric applications that several hypothesis tests are carried out at the same time. The problem then becomes how to decide which hypotheses to reject, accounting for the multitude of tests. In this paper, we suggest a stepwise multiple testing procedure which asymptotically controls the familywise error rate at a desired level. Compared to related single-step methods, our p...

PURPOSE: The purpose of this study was to record and analyze underwater sounds generated by a small hydraulic cutterhead dredge during maintenance dredging in the Stockton Deepwater Shipping Channel (SDWSC), California. Of particular interest was determining 1) the sound frequency characteristics of the excavation process, 2) the received sound pressure levels at various distances from the sour...

Most speci cation search processes select models based on some goodness of t statistic (i.e. R or related F ). The e ects of the sequential search on the statistical tests should be taken into account when looking for the maximum goodness of t. To avoid misspeci ed models it is useful to study the selected models based on the full sample, and along the sample. This paper presents a conditional ...

Building with Nature is a new approach to designing water infrastructure, one that seeks to realize socioeconomic project goals in harmony with the environment. The Dutch dredging industry is promoting its application in the Netherlands, but similar concepts are emerging internationally. The Working with Nature concept has been developed under the auspices of the World Association for Waterborn...

The study reported here presents the results of an investigation of a marsh-cove ecosystem heavily contaminated by cadmium. The most contaminated aquatic sediments were dredged in 1972-73, but the resuspension of the sediments and recycle of water from the dredge spoil resulted in reestablishment of a large contaminated sediment bed with concentrations very similar to those observed before dred...

Estuaries have been sites of intensive human activities during the past century. Tracing the evolution of subaqueous topography in estuaries on a decadal timescale enables us to understand the effects of human activities on estuaries. Bathymetric data from 1955 to 2010 show that land reclamation decreased the subaqueous area of Lingding Bay, in the Pearl River estuary, by ~170 km2 and decreased...

This paper addresses the development of a new method for synoptic monitoring of turbidity represented by Total Suspended Solids (TSS). The method aims at optimising information from operational dredging data, earth observation data, modelling of currents and sediment transport and in-situ data by means of new data-model integration (DMI) techniques. As a test case, Penny’s Bay in the Hong Kong ...
