Temperature effects in the sputtering of an organic molecule were investigated by subjecting a well defined film of coronene to Au1 and C60 primary ions at 100 and 300 K. Strong field photoionization of the sputtered neutral flux was employed to monitor the change in flight time and kinetic energy distributions of intact and fragmented species.

Using nine years of personnel records from a regional grocery store chain in the United States, this study examines the effect of manager ethnicity on the ethnic composition of employment at the firm’s 73 stores. We estimate separate models with store fixed effects for several departments and job titles at each store. We first compare the rates at which Hispanic and white non-Hispanic managers ...

The model y = ∑w j=1 Xjβj + e is generalized orthogonal if the orthogonal projection matrices on the range spaces of matrices Xj , j = 1, ..., w, commute. Unbiased estimators are obtained for the variance components of such models with cross-nesting.

New railway legislation in Sweden has increased the need for transparent access charges on the Swedish railway network. We estimate cost functions for infrastructure operation, maintenance and renewal in the Swedish national railway network, using unobserved effects models and calculate marginal costs for railway infrastructure wear and tear. We find evidence of unobserved fixed effects at a tr...

In this study, the author uses 25 years of data taken from the 1979 National Longitudinal Study of Youth to examine the relationship between family life course statuses and transitions and work-related health limitations. The author uses a detailed set of statuses and transitions that include marriage, divorce, cohabitation, and parenthood. The measures of health used tap health limitations in ...

This article discusses the information-structural status and the syntax of left and right dislocation constructions in Dutch. Four orthogonal information-structural features are proposed, and their distribution is systematically investigated. Furthermore, it is argued that hanging topic left dislocation, backgrounding right dislocation and afterthoughts are a particular kind of parenthesis. The...

Are CEOs’ attitudes and beliefs linked to their firms’ innovative performance? This paper uses Malmendier and Tate’s measure of overconfidence, based on CEO stockoption exercise, to study the relationship between a CEO’s “revealed beliefs” about future performance and standard measures of corporate innovation. We begin by developing a career concern model where CEOs innovate to provide evidence...

This paper builds a framework for analyzing models with multiple time-varying treatments when selection into treatment is sequential and varies across treatment statuses. The key challenge is to separate the time-varying effect of treatment from dynamic selection into treatment based on unobservables. To address this problem, we develop a method that is a hybrid between a control function and a...

This paper presents unique evidence that orphanhood matters in the long-run for health and education outcomes, in a region of Northwestern Tanzania. We study a sample of 718 nonorphaned children surveyed in 1991-94, who were traced and reinterviewed as adults in 2004. A large proportion, 19 percent, lost one or more parents before the age of 15 in this period, allowing us to assess permanent he...

Including individual as a independent random effect in the latent field is implemented the same way in INLA for all case studies in house sparrow population (Gaussian, binomial and Poisson). Note that in the Gaussian case study we have repeated measurements, i.e. possible several observation for each individual random effect, while in the binomial and Poisson cases there are only one observatio...
