An Assessment on the Cost Structure of the UK Airport Industry: Ownership Outcomes and Long Run Cost Economies [PDF]

In this paper we analyze the cost structure of the UK airport industry by estimating a variable cost function for the period 1994-2005. Overall results suggest that the long run average costs curve is U-shaped: it decreases until passenger traffic ...

Communicability Graph and Community Structures in Complex Networks [PDF]

, 2009
We use the concept of the network communicability (Phys. Rev. E 77 (2008) 036111) to define communities in a complex network. The communities are defined as the cliques of a communicability graph, which has the same set of nodes as the complex network ...

Atmospheric River Event Frequency Is the Principal Moisture Driver for Radial Growth of High‐Elevation Southern California, USA Conifers, 1658–2020 CE

International Journal of Climatology, EarlyView.
Conifers growing in high‐elevation alpine environments in the mountains of Southern California, USA, are highly responsive to atmospheric river (AR) events, which typically produce heavy precipitation over 1–3 days. However, it is the frequency of the AR events, not their magnitude nor annual precipitation totals, that most affects the radial growth of

Revisiting the Intellectual Legacy of H. Igor Ansoff: A Critical Analysis of His Contributions and Their Impact on the Evolution of Strategic Management

Strategic Change, EarlyView.
ABSTRACT This systematic review examines how H. Igor Ansoff's theoretical contributions have evolved in contemporary strategic management through cluster analysis of 116 publications (1968–2024). Four distinct research clusters were identified, revealing that Ansoff's legacy has shifted from theoretical foundations to pedagogical applications and ...

Population dynamics of Townsend's big‐eared bats: effect of age and drought on survival

The Journal of Wildlife Management, EarlyView.
We estimated age‐specific yearly survival of female Townsend's big‐eared bats in Inyo and Mono Counties, California. We found that both juvenile and adult survival were negatively impacted by drought, and that detection probability was lower for hand‐recapture than for bats detected via pass‐through antenna arrays.

Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).
