A unique set of physical and optical observations of sediment resuspension was obtained during the passage of two hurricanes, Edouard and Hortense. The eyes of these hurricanes passed within approximately 110 and 350 km, respectively, of our study site on the continental shelf (100 km south of Cape Cod, Massachusetts) within a two-week period in the fall of 1996. Sediments were resuspended to m...

Sensors have been increasingly used for many ubiquitous computing applications such as asset location monitoring, visual surveillance, and human motion tracking. In such applications, it is important to place sensors such that every point of the target area can be sensed by more than one sensor. Especially, many practical applications require 3-coverage for triangulation, 3D hull building, and ...

To understand tone and intonation in speech, we need to identify their functional components. To identify these components from the acoustic signal of speech, it is critical to recognize that they are not equivalent to any directly observable surface patterns. This is because, as will be argued in this paper, there are multiple degrees of separation between functional components of tone and int...

Gender Differences in Job Separation Rates and Employment Stability: New Evidence from Employer-Employee Data I analyze the job separation process to learn about gender differences in job separation rates and employment stability. An essential finding is that employer-employee data are required to identify gender differences in job separation probabilities because of labor market segregation. F...

To address complexity of modeling the world’s processes, over the years in different scientific disciplines separation assumptions have been made to isolate parts of processes, and in some disciplines they have turned out quite useful. It can be questioned whether such assumptions are adequate to address complexity of integrated human mental and social processes and their interactions. In this ...

Are couples who have been together longer more likely to stick together in the face of adversity? This paper uses monthly data from the Survey of Income and Program Participation to investigate the impact on relationship duration of labor market shocks such as layoff, discharge for cause, and disability. Using a Cox proportional hazard model, I show that generally these labor market shocks sign...

This paper uses readily accessible data to measure the probability that an employed worker becomes unemployed and the probability that an unemployed worker finds a job, the ins and outs of unemployment. The job finding probability is strongly procyclical and the separation probability is nearly acyclical, particularly during the last two decades. Using the underlying microeconomic data, the pap...

For any country, the stability of the financial system is critical to a healthy economy a point that becomes dramatically apparent when systemically important banks fail. This is equally true for a financial system dominated by foreign-owned banks as for one composed mainly of domesticallyowned banks. In either case, the supervisory authority and central bank whether home or host must ensure th...

In this paper we present a novel concept for navigation in virtual environments. While a variety of navigation metaphors have been proposed for immersive VR, desktop scenarios are typically based on mouse navigation, using a flying, walking or driving metaphor. Steering all six degrees of freedom in this way is a complicated task even for a trained user. We propose an innovative object-centered...

The study was undertaken to evaluate (a) the reliability of pedometer data and reactivity of children to wearing a pedometer, (b) the effectiveness of a missing data replacement procedure, and (c) the validity of the Leisure Time Exercise Questionnaire (LTEQ). Six days of pedometer data were collected from 299 middle-school children, followed by administration of the LTEQ. Six days of pedometer...
