Honey volatiles as a fingerprint for botanical origin: a review on their occurrence on monofloral honeys
Honeys have specific organoleptic characteristics, with nutritional and health benefits, being highly appreciated by consumers, not only in food but also in the pharmaceutical and cosmetic industries. Honey composition varies between regions according to the surrounding flora, enabling its characterization by source or type. Monofloral honeys may reach higher market values than multifloral ones. Honey's aroma is very specific, resulting from the combination of volatile compounds present in low concentrations. The authentication of honey's complex matrix, according to its botanical and/or geographical origin, represents a challenge nowadays, due to the different sorts of adulteration that may occur, leading to the search for reliable marker compounds for the different monofloral honeys. The existing information on the volatiles of monofloral honeys is scarce and disperse. In this review, twenty monofloral honeys and honeydews, from acacia, buckwheat, chestnut, clover, cotton, dandelion, eucalyptus, fir tree, heather, lavender, lime tree, orange, pine, rape, raspberry, rhododendron, rosemary, strawberry tree, sunflower and thyme, were selected for volatile comparison purposes. Taking into consideration the country of origin, the technique of isolation and analysis, the five main volatiles from each of the honeys are compared. Whereas some compounds were found in several types of monofloral honey, and thus not considered good volatile markers, some monofloral honeys revealed characteristic volatile compounds independently of their provenance.Funding: SFRH/BD/117013/2016, UID/AGR/00690/2019,

Artificial Intelligence acceptance : morphological elements of the acceptance of Artificial Intelligence
Inteligência Artificial tem-se desenvolvido muito rapidamente ao longo dos últimos anos, há medida que os algoritmos de machine learning vão evoluindo e ficando mais complexos, os robôs ficam cada vez mais autónomos, levando a um desenvolvimento mais rápido e à aparição de mais chatbots no suporte a variados serviços e assistentes pessoais como a Cortana e a Siri.
Esta rápida evolução permite que as empresas que adotam estas tecnologias possam vir a ganhar uma vantagem competitiva. No entanto, para que estas tecnologias se traduzam numa melhoria da performance das empresas, é de elevada importância que a Inteligência Artificial seja aceite e incentivada pelos colaboradores das empresas em questão.
Neste sentido, estudámos as teorias de aceitação da tecnologia existentes, adaptando o UTAUT para chegar a um novo modelo que permite compreender a aceitação de Inteligência Artificial. O instrumento de recolha de dados utilizado foi um questionário online que foi respondido por 321 pessoas com uma média de idades de aproximadamente 29 anos, sendo que cerca de 50% da amostra corresponde a pessoas com idades compreendidas entre os 22 e os 35 anos.
Os resultados obtidos foram bastante positivos, mostrando que a maioria das pessoas parece estar recetiva a esta tecnologia e achar que se trata de uma ferramenta útil.Artificial Intelligence is experiencing a fast progress in the last years, as machine learning algorithms evolve into more complex algorithms, robots gain autonomy, leading to a faster development of chatbots in the support to several services and personal assistants, such as Cortana and Siri.
This rapid evolution allows companies to obtain competitive advantages by adopting this type of technologies. However, in order for these technologies to improve the companies’ performance, employers, managers and employees have to accept Artificial Intelligence and foster the usage of these programs.
In this sense, we studied the existent technology acceptance theories, adapting the UTAUT to develop a model to study the acceptance of Artificial Intelligence. The instrument for collecting data used was an online questionnaire, that was answered by 321 people with an average of ages of approximately 29 years and 50% of the sample had ages between 22 and 35 years.
The results were very positive, showing that the generality of people seemed to be receptive to this technology, while thinking it can be an useful tool
Future financial institution for young population- value proposition concept with special focus on transactional banking products
CEMSThe present Work Project is centered on a CEMS MIM Business Project developed with MasterCard in Warsaw, Poland. The main outcomes of the project were a thorough knowledge of the FinTech industry and its future trends, a deep understanding of the preferences and expectations of university students and young workers regarding financial services and the suggestion of a value proposition for an innovative financial mobile application. The present report presents the methodology used to achieve the aforementioned outcomes, as well as a complete academic discussion focused on the theories concerning new product development

Financial impact of organizing international sports events
This work project aims to assess the capacity of international sports events to impact sports participation and sports development in Portugal, generate financial resources for sports federations, and provide positive out comes for local communities. For this purpose, three Portuguese sports federations were investigated, through semi-structured interviewees with key stakeholders, collection of event documents and reports, and the analysis of relevant sports data and statistics. The main findings point to an increase in thecompetitivenessandinternationalexperienceofthenationalathletes.Theorganization of events does not seem to constitute a financial risk, as federations can benefit from additional public subsidie
