How network topologies impact project alliance performance: evidence from the movie industry

Zhang, Xin-Jie ; Tang, Yong ; Xiong, Jason ; Wang, Wei-Jia ; Zhang, Yi-Cheng

In: Entropy, 2019, vol. 21, no. 9, p. 859

In many industries, partners are interconnected in project alliances that have limited lifespans and clearly-defined boundaries. The transparency of the movie industry provides a unique opportunity to study how alliance network topologies impact the performance of project alliances from the perspectives of social networks and organization theories. In this work, we compiled a massive movie...

Correlation of MLCTs of Group 7 fac-[M(CO)3]+ complexes (M = Mn, Re) with bipyridine, pyridinylpyrazine, azopyridine, and pyridin-2-ylmethanimine type ligands for rational photoCORM design

Kottelat, Emmanuel ; Lucarini, Fiorella ; Crochet, Aurelien ; Ruggi, Albert ; Zobi, Fabio

In: European Journal of Inorganic Chemistry, 2019, vol. 2019, no. 33, p. 3758–3768

A mathematical correlation of the MLCT absorption maxima of structurally related fac‐ [M(CO)3L2Br] complexes (M = Mn, Re; L2 = bidentate ligand) is obtained by the comparison of a total of 50 species bearing bipyridine, pyridinylpyrazine, azopyridine and pyridin‐2‐ylmethanimine L2 type ligands. The empirical relationship is first derived by the initial comparison of the MLCT absorption...

InvasiBES: Understanding and managing the impacts of Invasive alien species on Biodiversity and Ecosystem Services

Gallardo, Belinda ; Bacher, Sven ; Bradley, Bethany ; Comín, Francisco A. ; Gallien, Laure ; Jeschke, Jonathan M. ; Sorte, Cascade J. B. ; Vilà, Montserrat

In: NeoBiota, 2019, vol. 50, p. 109–122

Invasive Alien Species (IAS) are amongst the most significant drivers of species extinction and ecosystem degradation, causing negative impacts on ecosystem services and human well-being. InvasiBES, a project funded by BiodivERsA-Belmont Forum for 2019–2021, will use data and models across scales, habitats and species to understand and anticipate the multi-faceted impacts of IAS and to...

When and how java developers give up static type safety

Mastrangelo, Luis ; Hauswirth, Matthias (Dir.) ; Nystrom, Nathaniel (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 2019INFO008.

The main goal of a static type system is to prevent certain kinds of errors from happening at run time. A type system is formulated as a set of constraints that gives any expression or term in a program a well-defined type. Besides detecting these kinds of errors, a static type system can be an invaluable maintenance tool, can be useful for documentation purposes, and can aid in generating ...

Direct and indirect effects based on changes-in-changes

Huber, Martin ; Schelker, Mark ; Strittmatter, Anthony

(Working Papers SES ; 508)

We propose a novel approach for causal mediation analysis based on changes-in- changes assumptions restricting unobserved heterogeneity over time. This allows disentangling the causal effect of a binary treatment on a continuous outcome into an indirect effect operating through a binary intermediate variable (called mediator) and a direct effect running via other causal mechanisms. We...

Bank risk appetite in a world of CoCos

Aquila, Cecilia ; Barone Adesi, Giovanni (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018ECO015.

We investigate the shape of risk appetite when the bank is financed also with contingent convertible bonds (CoCos). Our contribution to the existent literature is to assess risk appetite in a multi-dimensional perspective and to account for differences among banks' clusters, especially in a world with CoCos and policy rates approaching zero or negative figures. In our model, the bank objective...

Contesting categories: cross-border marriages from the perspectives of the state, spouses and researchers

Moret, Joëlle ; Andrikopoulos, Apostolos ; Dahinden, Janine

In: Journal of Ethnic and Migration Studies, 2019, p. 1-18

Marriages that involve the migration of at least one of the spouses challenge two intersecting facets of the politics of belonging: the making of the ‘good and legitimate citizens’ and the ‘acceptable family’. In Europe, cross-border marriages have been the target of increasing state controls, an issue of public concern and the object of scholarly research. The study of cross-border...

Reward processing under influence : Effects of stress and cognitive load on reward processing, and their clinical implications for the vulnerability to major depression

Gaillard, Claudie ; Martin Soelch, Chantal (Dir.)

Thèse de doctorat : Université de Fribourg, 2019.

Humans have a propensity to pursue rewards and to avoid punishments. The motivation to seek rewards and the ability to experience and to learn from positive consequences are fundamental functions in the reward processing. They promote survival and well-being. However, these functions can be challenged or impaired by stressful events or contexts. To clarify the determinant factors that might...

Modeling latent variables in economics and finance

Bluteau, Keven ; Ardia, David (Dir.) ; Boudt, Kris (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2019 ; 2758.

The subject of unobservable variables encompasses this thesis. These latent (i.e., unobservable) variables must be inferred using statistical models or observable proxies. The objectives of my doctoral thesis are to develop and test new statistical models to infer these variables and link them to the analysis and improvement of economic and financial decisions. In my first essay, I tackle...

Three essays in labor economics

Gentili, Elena ; Mazzonna, Fabrizio (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 2019ECO003.

In this thesis, I investigate two of the main challenges faced by developed societies: aging and migration. In the first chapter, I consider the cultural determinants of elderly care arrangement decisions. The empirical strategy focuses on the three German and French speaking Swiss bilingual cantons. Particularly, since the structure of long-term care provision is planned at cantonal level, I...
