Digitalization and international digital marketing: A review and research agenda
Silva, A.; Lourenço, C.; Leitão, L.; Marques, R.; Proença, M.; Meneses, F.With the growing need for digitalization in international marketing, this article explores how digital transformation facilitates the interaction between producers and consumers, promoting the introduction of products and services into the global market in a more efficient and cost effective way. Digital technologies can assist processes, reduce costs, increase competitiveness and enable entry into new markets,...
Avaliação do potencial de exploração dos recursos hidrominerais e geotérmicos e...
Madureira, P.; Cerdeira, R.; Lourenço, C.; Francisco, J.; Coelho, Luis Manuel RodriguesEnergy sustainability presents challenges as how to reduce resource consumption and how to make better use of renewable ones. For this purpose, the characterization of the existing endogenous resources is essential. The aim of this project was to evaluate the exploitation potential of hydromineral and geothermal resources and their use for temperatures above 25°C, in 39 concessions. The results allowed verifyin...
Design of management accounting systems in public administration: A case study
Frias, A.; Conceição, A.; Lourenço, C.Purpose: Many public entities experience difficulties in designing and implementing a Management Accounting and Control System (MACS). This work aims to design a MACS implementation framework for a public sector organization, constituting a useful tool for other public organizations conducting a similar task. Design/methodology/approach: Following an interventionist research, a comprehensive case study of the o...
Design of management accounting systems in public administration: A case study
Frias, A.; Lourenço, C.; Conceição, A.Purpose: This work aims to design a management accounting system (MAC) framework for a public sector organization. Many public entities experience difficulties in designing and implementing MACs. Our proposal intends to be as a useful tool in the accomplishment of this task. Methodology: A comprehensive case study of the organizational structure and operational activity was performed, following an interventioni...

Sirunyan, A. M.; Tumasyan, A.; Adam, W.; Ambrogi, F.; Asilar, E.; Bergauer, T.; Brandstetter, J.; Dragicevic, M.; Erö, J.; Escalante Del Valle, A.Made available in DSpace on 2022-04-28T19:11:08Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-09-17; The observation of the standard model (SM) Higgs boson decay to a pair of bottom quarks is presented. The main contribution to this result is from processes in which Higgs bosons are produced in association with a W or Z boson (VH), and are searched for in final states including 0, 1, or 2 charged lepto...
