The financial and green effects of cultural values on mission drifts in European social enterprises
Business Strategy and the Environment, Volume 32, Issue 1, Page 1-29, January 2023., 2023 Abstract The sustainable social enterprises (SEs) literature shows that SEs have to simultaneously pursue economic, social, and environmental aims. However, tensions between these objectives can make this a challenging task and lead towards mission drift. This work investigates if the cultural dimension can forecast the mission drift.

Array BP-XOR Codes for Hierarchically Distributed Matrix Multiplication [PDF]
, 2019 A novel fault-tolerant computation technique based on array Belief Propagation (BP)-decodable XOR (BP-XOR) codes is proposed for distributed matrix-matrix multiplication. The proposed scheme is shown to be configurable and suited for modern hierarchical compute architectures such as Graphical Processing Units (GPUs) equipped with multiple nodes ...

Symmetry Breaking in Occupation Number Based Slave-Particle Methods [PDF]
Phys. Rev. B 96, 165135 (2017), 2017 We describe a theoretical approach for finding spontaneously symmetry-broken electronic phases due to strong electronic interactions when using recently developed slave-particle (slave-boson) approaches based on occupation numbers. We describe why, to date, spontaneous symmetry breaking has proven difficult to achieve in such approaches.

Film‐Based Multi‐Photon Lithography for Efficient Printing of Electromagnetic Surface Structures
Advanced Materials Technologies, EarlyView.This work introduces film‐based multi‐photon lithography as an efficient method for fabricating electromagnetic surface structures with 2D and 2.5D geometries, particularly THz and mid‐IR metasurfaces. These structures can be fabricated on various substrates, such as glass or silicon‐on‐insulator, over areas ranging from mm2 to cm2, achieving feature ...

Business Strategy and the Environment, Volume 32, Issue 1, Page 72-95, January 2023., 2023 Abstract Sustainable entrepreneurs operating in protected areas face distinctive barriers that place additional emphasis on the need to build legitimacy. To date, how they do this has not been entirely explored. This paper addresses this need through an exploratory study of sustainable entrepreneurs in a transnational protected area.

Estimating conditional probabilities of historical migrations in the transatlantic slave trade using kriging and Markov decision process models [PDF]
arXiv, 2020 Intra-African conflicts during the collapse of the kingdom of Oyo from 1817 to 1836 resulted in the enslavement of an estimated 121,000 people who were then transported to coastal ports via complex trade networks and loaded onto slave ships destined for the Americas.

Benchmarking the simplest slave-particle theory with Hubbard dimer [PDF]
Chin. Phys. B Vol. 28, No. 10 (2019) 107103, 2018 Slave-particle method is a powerful tool to tackle the correlation effect in quantum many-body physics. Although it has been successfully used to comprehend various intriguing problems, such as Mott metal-insulator transition and Kondo effect, there is still no convincing theory so far on the availability and limitation of this method.
