Abstract:
... English for Specific Purposes (ESP) and Needs Analysis (NA) have been studied to a great extent, since a couple of decades ago. The review of the related studies also shows that needs analysis has been of much concern to the researchers interested in the ESP field. However, ESP for the students of marine engineering has not been investigated in terms of the task-based language needs. The researche ...

Abstract:
... In their discussion of stochastic complementarity, Manzini et al. (2018) show that the intuitively appealing correlation criterion does not—in general—satisfy the axiom of monotonicity: products classified as complements can turn into substitutes following an increase in their joint purchases. In this note, we show that, however, by restricting attention to mixed logit models along the lines of Ge ...

Abstract:
... In conventional structural vector autoregressive models it is assumed that there are at most as many structural shocks as there are variables in the model. It is pointed out that heteroskedasticity can be used to identify more shocks than variables. Results are provided that allow a researcher to assess how many shocks can be identified from specific forms of heteroskedasticity. ...

Abstract:
... Three metrics of species diversity – species richness, the Shannon index and the Simpson index – are still widely used in ecology, despite decades of valid critiques leveled against them. Developing a robust diversity metric has been challenging because, unlike many variables ecologists measure, the diversity of a community often cannot be estimated in an unbiased way based on a random sample from ...
