Identity reinforcement or risky organizational change? : Category spanning in humanitarian projects

Kooijman, Eva A. P. ; Beck, Nikolaus

In: Administrative sciences, 2021, vol. 11, no. 4, p. 17

In this study, we investigate the consequences of organizational change that consist of adding new categories to the portfolio of humanitarian organizations. Our aim is to discern differences in these consequences between specialist and generalist organizations. Previous research has shown that spanning categories lead to disadvantages in the evaluation of organizations by audience members in...

MAcroecological Framework for Invasive Aliens (MAFIA): disentangling large-scale context dependence in biological invasions

Pyšek, Petr ; Bacher, Sven ; Kühn, Ingolf ; Novoa, Ana ; Catford, Jane A. ; Hulme, Philip E. ; Pergl, Jan ; Richardson, David M. ; Wilson, John R. U. ; Blackburn, Tim M.

In: NeoBiota, 2020, vol. 62, p. 407–461

Macroecology is the study of patterns, and the processes that determine those patterns, in the distribution and abundance of organisms at large scales, whether they be spatial (from hundreds of kilometres to global), temporal (from decades to centuries), and organismal (numbers of species or higher taxa). In the context of invasion ecology, macroecological studies include, for example,...

High-performance interior point methods : application to power grid problems

Kardoš, Juraj ; Schenk, Olaf (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020INFO003.

A software library for the solution of large-scale structured nonconvex optimization problems is presented in this work, with the purpose of accelerating the solution on single- core, multicore, or massively parallel high-performance distributed memory computing infrastructures. A large class of industrial and engineering problems possesses a particular structure, motivating the development of...

Life-history evolution and the genetics of fitness components in drosophila melanogaster

Flatt, Thomas

In: Genetics, 2020, vol. 214, no. 1, p. 3–48

Life-history traits or “fitness components”—such as age and size at maturity, fecundity and fertility, age-specific rates of survival, and life span—are the major phenotypic determinants of Darwinian fitness. Analyzing the evolution and genetics of these phenotypic targets of selection is central to our understanding of adaptation. Due to its simple and rapid life cycle, cosmopolitan...
