Email fraud classifier using machine learning

Treballs Finals de Grau d'Enginyeria Informàtica, Facultat de Matemàtiques, Universitat de Barcelona, Any: 2020, Director: Jordi José Bazán[en] Email is one of the most common methods of communication nowadays. Programs known as malware detection are essential to assist and protect users from the agents that are usually responsible for cyberattacks. This paper focuses on using machine learning algorithms to detect any possible email attacks by analyzing datasets of whitelists and blacklists. This document also includes other methods that try to solve this problem

Macroeconomic effects of fiscal consolidations in a DSGE model for the Euro Area: does composition matter?

We develop a new-Keynesian DSGE model with an extended fiscal policy block to assess the conditions for expansionary fiscal consolidations. In addition to several taxes, we consider public employment expenditures and government spending, which may have different degrees of productivity. We calibrate the model for the Euro Area and use it to simulate alternative fiscal consolidations with changes in the budget composition. Among the main conclusions we find that: (i) if conducted with a cut in weaklyproductive spending and a symmetric increase in highly-productive spending, fiscal consolidations have expansionary effects on investment and output; (ii) if consolidation is pursued through a pure reduction in weaklyproductive public employment, the effects on output decrease with the degree of labor market competition and turn out to be positive under perfect competition.fiscal policy, fiscal consolidation, new-Keynesian DSGE model

Religious Tourism & The Azorean Diaspora in the USA

The article focuses on the Azorean diaspora in North America in historic and cultural terms. The analysis of official tourist reports and inquiries, newspaper articles and Online sources allow us to perceive which generations preserve the religious factor as pivotal for the attendance of the events, and which one/s already reveal shifting trends. Religion is still an important element to summon the Azorean diaspora spread across the USA. The Ecce Homo procession is celebrated in towns like Fall River (Massachusetts) and Half Moon Bay (California), although Ponta Delgada (São Miguel island) still remains the devotional core – the former and the latter have been sister cities for decades. Also the Holy Ghost festival is pivotal both in Fall River and across Terceira island (Leal, 2005). Observation shows that while the older generations maintain their religious and emotional bonds to the family core in the Azores, the younger ones present a different tourist behaviour in terms of travel and accommodation patterns (ORT/CESTUR, 2009)

Information and knowledge society in the European Union: priorities of the Lisbon Strategy

Actualmente, vivemos na era da "Revolução Digital". Na verdade, os últimos dez anos têm assistido a uma difusão, sem precedentes, das Tecnologias da Informação e da Comunicação (TIC). Perante a globalização e a celeridade das mudanças tecnológicas, a União Europeia lançou a Estratégia de Lisboa, em 2000, com um objectivo estratégico: «transformar a Europa na economia baseada no conhecimento mais dinâmica e competitiva do mundo». Neste contexto, a Estratégia de Lisboa reconhece a importância das TIC no estímulo à competitividade, à inovação, na sociedade da informação e do conhecimento, e na economia baseada no conhecimento.Nowadays we live in 'Digital Revolution' era. In fact, the last ten years has witnessed an unprecedented diffusion of Information and Communication Technologies (ICT). Facing globalisation and faster technological change, European Union has launched the Lisbon Strategy, in 2000, who aim a strategic goal: «to become the most competitive and dynamic knowledge-based economy in the world».

Food and leisure habits among young people of Douro Region (Portugal)

This is an descriptive and transversal study whose purpose is to characterize the life style of young people of a sample constituted for high school students (School A) and professional school students (School B), both placed in Douro Region. Some study objectives are: (i) to know the food habits of study sample; (ii) to characterize the leisure activities; (iii) to classify the type of physical exercise practised; (iv) to identify thematics that need to be worked in health education. The data was collected by a questionnaire self-conducted on line, drew to the effect and the anonymity guaranteed. To data treatment we turned to a statistical package (SPSS). They answered to a questionnaire 95 students, 57,9% of school A and 42,1 % of school B. School A: sex - 55,0% feminine and 45,0% masculine; age average – 11,5 ± 1,34 years. School B: sex – 56,4 % feminine and 43,6% masculine; age average – 17,76 ± 1,83 years. In the school A, students make the first meal between 7.15 a.m. and 00.30 p.m., that in large majority is the breakfast (90%). They have breakfast all days (85,0%) and all students have lunch and dinner. The students that live more far from school are whose that have breakfast many times (Kruskal Wallis: p=0,033). However, only, 25,0% and 20,0% ingest, respectively, fruits and vegetables. We classified like thin 40% of the students. Only 5,0% practice physical exercise, 2 days a week. The leisure activity, almost exclusive, is watch TV (90,0%). In the school B, the students have the first meal between 6.30 a.m. and 1.20 p.m., that for 94,5% is the breakfast. Have all days a week breakfast, lunch and dinner, respectively, 67,3%, 83,6% and 80,0% of students and only 21,8% and 10,9% ingest, respectively, fruits and vegetables all days: The boys ingest many times a week vegetables than the girls (Mann Whitney: p=0,019). In sample B, 60,0% practice physical exercise, predominantly (29,1%), 2 days a week. The boys practice many times than the girls (2: p= 0,014). The leisure activities are more diversificated: 81,8% watch TV and 74,5% meet friends. There are 12,7 of students with excess of weight. We conclude about our study subjects that it’s necessary to insist on the importance of have a breakfast and a consumption of fruits and vegetables all days a week and to practice physical exercise with regularity, whose will contribute for a adequate weight and a healthy life.Fundação para Ciência e Tecnologia (FCT) - LIBEC/CIFPEC - unidade de investigação (16/644

Integrated solution of a back office system for serious games targeted at physiotherapy

Serious games targeted at physiotherapy can be a solution to help the physical therapy professionals. However, the entire game management, in its various aspects, is under the professional's responsibility. One way to reduce the professional management work will be to integrate a Back Office system in the game. Following this trend, the purpose of this paper is to present a modular Back Office system for centralized management of one or more games targeted at physical therapy.This work has been supported by Fundac ¸˜ ao para a Ci ˆ encia e Tecnologia (FCT) in the scope of the project: UID/CEC/ 00319/2013.

Corporate governance nas empresas familiares em contexto de sistemas produtivos locais

O envolvimento de famílias em empresas é observável nas economias de todo o mundo, apesar das diferenças evidentes entre países diferentes, não só no que diz respeito à sua predominância nas economia, mas também ao tipo de envolvimento que se pode observar. Esta investigação visa compreender a gestão das empresas familiares quando comparados com os das empresas não familiares, nomeadamente em termos de corporate governance. A análise é baseada em dados secundários de estudos de caso recolhidos da literatura e em dados primários obtidos para se perceber qual o impacto que a organização empresarial familiar tem na relações intra e inter-empresas. Estes estudos de caso possibilitam a oportunidade de comparar as empresas familiares em Portugal, por um lado, e nas economia Anglo-saxónicas, por outro. Este estudo demonstrou que há diferenças importantes no mundo dos negócios em países em que a família é uma instituição muito dominante na sociedade (onde o negócio é baseado em laços fortes, existe uma relação harmoniosa entre os membros da família, e a família é aceite localmente e domina a organização da empresa) e nos países onde a família desempenha um papel mais marginal n sociedade e economia. Os resultados obtidos dos dados primários confirmam a teoria e outros estudos empíricos investigados. Assim, este artigo mostra quais os factores determinantes na estrutura de corporate governance nas empresas familiares sublinhando as vantagens e desvantagens destas em comparação com empresas não familiare
