Holocene sea‐level and environmental changes on the Isle of Mull, Scotland

Journal of Quaternary Science, EarlyView.
ABSTRACT Sea‐level and coastal changes are reconstructed on the Isle of Mull, western Scotland, from 10 988 to 10 507 cal BP to the present. This research has produced the first SLIP for the Isle of Mull. A multiproxy approach including pollen, spore, foraminifera and diatom analyses reveals palaeoenvironmental changes from two coastal sites.

The song of the dunes as a self-synchronized instrument

, 2006
Since Marco Polo (1) it has been known that some sand dunes have the peculiar ability of emitting a loud sound with a well defined frequency, sometimes for several minutes. The origin of this sustained sound has remained mysterious, partly because of its

Holocene palaeoenvironmental reconstruction of sea level, coastal and vegetation changes along the southern Solway Firth, United Kingdom

Journal of Quaternary Science, EarlyView.
Abstract Holocene relative sea level (RSL) changes were reconstructed from four sites along the less‐studied southern Solway Firth. A multiproxy approach, including lithostratigraphical and biostratigraphical analyses, combined with radiocarbon dating, produced ten sea level index points (SLIPs).

Modelling formation and evolution of transverse dune fields

, 2006
We model formation and evolution of transverse dune fields. In the model, only the cross section of the dune is simulated. The only physical variable of relevance is the dune height, from which the dune width and velocity are determined, as well as ...

Sand transverse dune aerodynamics: 3D Coherent Flow Structures from a computational study [PDF]

, 2015
The engineering interest about dune fields is dictated by the their interaction with a number of human infrastructures in arid environments. Sand dunes dynamics is dictated by wind and its ability to induce sand erosion, transport and deposition.

A twofold development and demise of pine stands in the Netherlands during the Allerød interstadial: two hypotheses to explain a link to climate change recorded in Greenland ice

Journal of Quaternary Science, EarlyView.
ABSTRACT The second half of the Allerød interstadial in the Netherlands is characterised by pine forest. Excavated trunks of 165 pine trees at Leusden‐Den Treek in the central Netherlands (LETR16) were dated by dendrochronology and radiocarbon. Two chronologically separated pine forest phases occurred during relatively warm periods as recorded in ...

Internationalization, Dynamic Capabilities, and Innovation: Unveiling the Impact on Hotel Chain Performance

Strategic Change, EarlyView.
ABSTRACT The indirect effect of dynamic capabilities on performance has recently emerged as a topic of significant interest and debate in management research. In turbulent environments such as the international hotel industry, where companies constantly innovate to improve their performance, it is important to consider the effect of these dynamic ...

On the shape of barchan dunes

, 2005
Barchans are crescent-shaped sand dunes forming in aride regions with unidirectional wind and limited sand supply. We report analytical and numerical results for dune shapes under different environmental conditions as obtained from the so-called `minimal

Is It a Matter of Visibility Over Viability? CEO Narcissism and the Strategic Trade‐Off in Corporate Diversification

Strategic Change, EarlyView.
ABSTRACT This study examines how CEO narcissism shapes corporate diversification strategies, addressing gaps in upper echelon and agency theories. Using a sample of 388 CEOs across 319 firms, we find that narcissistic CEOs drive higher levels of overall corporate diversification but exhibit a strategic trade‐off: they strongly favor unrelated ...
