The first international workshop on Data-driven Personalisation of Television aims to highlight the significantly growing importance of data in the support of new television content consumption experiences. This includes automatic video summarization, dynamic insertion of content into media streams and object based media broadcasting, to serve the recommendation of TV content and personalization in media delivery. The workshop has two keynote talks alongside five paper presentations and several related demos.

With the electricity market liberalization, distribution and retail companies are looking for better market strategies based on adequate information upon the consumption patterns of its electricity customers. In this environment all consumers are free to choose their electricity supplier. A fair insight on the customer´s behaviour will permit the definition of specific contract aspects based on the different consumption patterns. In this paper Data Mining (DM) techniques are applied to electricity consumption data from a utility client’s database. To form the different customer´s classes, and find a set of representative consumption patterns, we have used the Two-Step algorithm which is a hierarchical clustering algorithm. Each consumer class will be represented by its load profile resulting from the clustering operation. Next, to characterize each consumer class a classification model will be constructed with the C5.0 classification algorithm.

The European Project Semester (EPS) project-based learning framework is a multicultural and multidisciplinary one semester engineering capstone programme provided by a network of European Higher Education institutions. Its aim is to prepare 3rd-year undergraduate students to their future professional life, enhancing hard and soft skills and following ethical and sustainable design and development practices. At the School of Engineering of Porto Polytechnic (ISEP) the focus of the EPS programme (EPS@ISEP) is on solving multidisciplinary problems through teamwork, involving engineering, design and business students [1]. The students work in teams of 5 to 6 students, assembled according to the identified Belbin team roles, and also maximizing student cultural and scientific diversity. On the first week each team chooses to solve one of the open-ended multidisciplinary problems on offer. Those projects involve typically some type of automation and control[2]. One of the obstacles these eclectic teams face is the lack of hardware/software skills required to design, assemble and test a microcontroller based systems. To help overcome this situation, the programme syllabus includes an 8-hour intensive "Arduino & Electronics Crash Course" at the beginning of the semester due to its market penetration, low-cost, availability of documentation and support, and soft learning curve. This course has effectively contributed to provide students with the necessary knowledge to design and implement simple control systems, leading to the adoption in multiple EPS@ISEP past projects of the Arduino platform/ecosystem. However, the crescent sophistication of the projects, namely the integration with Internet of Things (IoT) platforms, requires the definition of a new strategy, considering the available hardware/software alternatives. This paper analyses the experience of the EPS@ISEP students regarding the use of microcontroller based platforms in the development of engineering capstone projects, and proposes possible future hardware/software alternatives, both from the technical and pedagogical perspectives.

Nowadays, with the widely usage of on-line stream video platforms, the number of media resources available and the volume of crowd-sourced feedback volunteered by viewers is increasing exponentially. In this scenario, the adoption of recommendation systems allows platforms to match viewers with resources. However, due to the sheer size of the data and the pace of the arriving data, there is the need to adopt stream mining algorithms to build and maintain models of the viewer preferences as well as to make timely personalised recommendations. In this paper, we propose the adoption of optimal individual hyper-parameters to build more accurate dynamic viewer models. First, we use a grid search algorithm to identify the optimal individual hyper-parameters (IHP) and, then, use these hyper-parameters to update incrementally the user model. This technique is based on an incremental learning algorithm designed for stream data. The results show that our approach outperforms previous approaches, reducing substantially the prediction errors and, thus, increasing the accuracy of the recommendations.

Future engineering professionals are expected to be technically and scientifically sound, work in international and interdisciplinary teams and, above all, be able to systematically adopt sustainable and ethical design and development practices. These are the challenges faced nowadays by engineering undergraduates and engineering programmes. The European Project Semester (EPS) is a capstone programme offered by a network of European universities to engineering, project design and business undergraduates. Its goal is to prepare engineering undergraduates for their future profession by exposing them to one semester of project-based, multicultural and multidisciplinary teamwork where both hard and soft skills are matured. The Portuguese programme, which is run by Instituto Superior de Engenharia do Porto (ISEP) since the academic year of 2010-2011, emphasises additionally on the ethical and sustainability dimensions of engineering project development. This paper describes how EPS@ISEP achieves this goal by introducing the programme, defining and applying an analysis framework to illustrative robotic projects developed within the programme, identifying and collecting evidences of ethical design and development practices.

Como nos explica Rosales López (2012), o ato de planificar é uma prática específica da ação docente e, como tal, é essencial que os professores em formação desenvolvam competências no âmbito desta temática. Na mesma linha de pensamento, Roldão (2017) advoga a necessidade de se investigarem os processos pelos quais o cur r ículo - na sua dinâmica prescr ita - é, efetivamente, concretizado nos contextos educativos. Partindo destes pressupostos, no presente artigo temos como objetivo analisar as características das planificações desenhadas por futuros professores de História, aquando da prática educativa supervisionada, nomeadamente os contributos decorrentes dos estudos curriculares, bem como aqueles que são mais específicos da educação histórica (Barca, 2009), aí patentes. Para tal, optamos por uma análise documental de nove planificações provenientes de três instituições universitárias portuguesas distintas. Numa aproximação à Grounded Theory foi nosso propósito, também, criar uma planificação-tipo, enquanto retrato das principais tendências notadas. No final, verificamos que a direção tomada pelos futuros docentes pode ler-se a partir de dois eixos distintos: i) uma linha de pensamento curricular influenciada pelas teorias mais tradicionais e burocráticas, privilegiando, quase por inerência, estratégias pedagógicas assentes na ação primordial do professor e fundamentalmente expositiva; ii) a não integração de alguns dos mais relevantes princípios da educação histórica - a saber, a prevalência das destrezas do pensamento histórico, a diversidade de fontes de facto exploradas e uma recorrente relação intertemporal - evidenciando que, ainda na formação inicial, se valorizam mais os conhecimentos substantivos em detrimento dos saberes sobre História (Seixas, 2017).

Over the last decades, the tourism sector has seen progressive exponential growth, which has consolidated its position in the world as one of the most important economic activities. The main information sources should be privileged, as they will be an essential bridge of contact, gathering information and clarifying contacts between the destination and potential demand, but also for tourists already at the destination. The main objective of this study is to understand which feedback channels exist in a back-office environment, in the “Hospitality and commercialization” department of the Porto Tourism Association, A.R. - Porto Convention & Visitors Bureau. In addition, it will also be objective to understand how demand behaves through each input channel. In order to meet the objectives of this study, two possible analyses were created - one concerning the back-office sales in 2018, and the other related to requests for information via Live Chat tool, between November 2018 and March 2019. 338 contacts were verified which resulted through back-office sales (from 11 feedback channels) and 4196 conversations started in the live tool existing on the Visit Porto and Visit Porto and North websites. The data collected confirm that tourists prioritize three main feedback channels - Chat, Email - visitportoandnorth and Telephone. Chat and Telephone channels are mainly used by families and groups of friends, who search for cruises, prefer short stays and book shortly in advance, in the same month of the visit or just the previous month. On the other hand, the email - visitportoandnorth channel, mainly prioritized for more professional and business visits, is used by travel agencies (TA)/tour operators (TO), valuing the advance and investing in organized and tailored circuits concerning the destination visit.

In this article, we intend to present literary tourism as a growing trend of cultural tourism. In fact, tourism and literature have a common element, the trip. Travelling, as an activity of making journeys, is an element of connection between different places and peoples and, therefore, it plays a crucial role in the tourism activity. Literature may be of great importance as it can make a place immortal, strengthening the growth of literary pilgrims, and satisfy the demands of cultural tourism. Literary tourism has several dimensions, being motivated by the interest concerning an author, in a literary creation or setting, or in the cultural heritage of a destination. This research concludes that it is important to understand visitor’s needs, and places linked to authors or literary creations must be used to promote destinations more proactively, having the support of local communities.

This article aims to highlight the importance of segmenting and bringing a consensual definition on food tourism, gastronomic tourism and culinary, in the international Academia. We will then focus on culinary tourism as a market trend, also recognizing the food trends, grouped as products in this typology of food tourism. As a way of achieving the proposed objective, we proceeded to select indicators of trends in the area of food tourism, based on a review of the scientific literature. As a result of the literature review, two models are presented, one of the definitions of culinary tourism, based on five components, the other as a model of creation of new touristic food products. Finally, with this review, we wish to contribute to the recognition of more accurate market strategies towards these types of food tourism, impaired with the respect for local and regional heritages of the touristic destinations.

The growth of the elderly population is a transversal phenomenon to almost all the countries in the world. In recent years we have seen a growing elderly desire to improve their quality of life and well-being, while increasing interest in this segment of life by governments and, especially, by tourism companies [15]. Studies developed by [9,10,19,27,34] show, in European continent, the will of each of the parts to participate in social tourism. Portugal and Spain follow the global trend and, to mitigate the constraints inherent to advanced age, and others related to health, social and economic difficulties, promote, respectively, the social tourism programs by INATEL and IMSERSO.

The city of Oporto assumes a decisive role in the North region of Portugal, as a tourism destination. In addition to the recognized material and intangible heritage, the city has been developing strategies to create partnerships with regional and national stakeholders in order to program events of different typologies, throughout the year, with benefits for the city and the region. The music festivals are one of the activities programmed with the greatest expression in the city, nowadays. The present research, integrated in a broader project, aims to highlight the importance of the programming of events. In view of this purpose, this article will discuss the need to adapt music festivals to the target audience, in order to adjust the offer with positive results at the level of behavioural attitudes of tourists, regarding the intention to repeat and recommend the event (and destination).

This article aims to emphasize the importance and function of the landscape as a tourism resource, increasingly valued in tourism destinations. The landscapes are the subject of discussion and the object of sensitization to the valorisation and preservation in recent years. Nowadays, the landscape has acquired a greater appreciation on the part of society, because it is often assigned values representative by one or more sets of individuals. The valuation of the landscape allowed to create regulations and legislation related to its preservation and maintenance. In this sense, this research focuses on the importance of the landscape as a tourism resource and its impact on the motivation and preferences of the tourist in the northern region of Portugal as a tourism destination. Results demonstrate the preference about “coastal landscape”, followed by “mountain landscape”; also, Porto Metropolitan Area is notably the most visited region in the North of Portugal, followed by the Douro region. Most respondents agree that they usually include viewpoint in their journey plans, emphasizing “natural viewpoints”.

In competitive electricity markets with deep concerns for the efficiency level, demand response programs gain considerable significance. As demand response levels have decreased after the introduction of competition in the power industry, new approaches are required to take full advantage of demand response opportunities. Grid operators and utilities are taking new initiatives, recognizing the value of demand response for grid reliability and for the enhancement of organized spot markets’ efficiency. This paper proposes a methodology for the selection of the consumers that participate in an event, which is the responsibility of the Portuguese transmission network operator. The proposed method is intended to be applied in the interruptibility service implemented in Portugal, in convergence with Spain, in the context of the Iberian electricity market. This method is based on the calculation of locational marginal prices (LMP) which are used to support the decision concerning the consumers to be schedule for participation. The proposed method has been computationally implemented and its application is illustrated in this paper using a 937 bus distribution network with more than 20,000 consumers.

The Eurocity Chaves-Verín, as an European Grouping of Territorial Cooperation (EGTC), will be the central region to address in this work, focusing particularly on the issue of good practices taken into account in the existing cooperation link in these two cross-border regions, regarding the Thermal and Water Route Verín-Chaves-Vidago, as a leading proposal that fits and complements other offerings, creating competitiveness prospects for the destination, based on the quality offer, solely in endogenous resources, diversity of complementary tourism products, resulting in advantages for the stakeholders of the destination by extending the average stay and reducing seasonality. The results of the research show that the appreciation of the complementarity of the products made available to tourists, can effectively culminate in the increasing competitiveness of the destination, if the partnerships are valued and concretized, and if the stakeholders demonstrate openness regarding the proposals of the EGTC, concerning the valorisation, planning and promotion of tourism products arising from both regions.

The Paiva Walkways, in Portugal, opened in 2015, gave an important impulse to the tourism dynamic of Arouca municipality. This tourist attraction lacks scientific studies, in the context of tourism. Thus, it was developed a study about the tourist motivation of international visitors of this infrastructure, in the year 2018. The main goal of this research is to understand if the sources of information available (distribution channels) on the Paiva Walkways influence the motivation of the visit, concerning international demand. It was used a quantitative methodology through survey by questionnaire, sent via e-mail to 3639 contacts contained in the database relating to the reservations that were made online. The results of the hypothesis show the relation between the Push dimension and: official website of Paiva Walkways, websites with information about Paiva walkways, family and friends’ recommendation, Tourist office in Arouca, brochures about Paiva Walkways, guides (on paper), and blogs, forums or social networks. Also, a statistically significant positive relationship between the Pull dimension and official website of Paiva Walkways, websites with information about Paiva Walkways, family and friends’ recommendation, travel agency and/or tour operator, tourism office (outside of Arouca), tourism office in Arouca, brochures about Paiva Walkways, guides (on paper), blogs, forums or social networks, radio and television, tourism fair and previous experience. On average, the importance is higher for “Official website of Paiva walkways”, followed by “Websites with information about Paiva walkways”, items with a mean value much higher than the intermediate point of the measurement scale.

The northern region of Portugal, in the last years, has experienced the enhancement of tourism demand, which may induce the emergence of an over tourism phenomenon in some particular subregions of the North of Portugal. This phenomenon may cause significant destruction of the living conditions of residents, landscapes, seascapes, air and water quality, causing economic inequalities and social exclusion. The aim of this research paper is to understand if the phenomena of over tourism is present in the North of Portugal and if it changed overtime. The concentration of tourism activity in different municipality subregions can be measured with the Herfindahl-Hirschman Index a well know economic concentration measure. Using as variables the number guest and their expenditure in accommodation, to measure the demand, and the number of establishments, bedrooms and lodging capacity to measure the supply was possible to follow the concentration of tourism demand and supply in the 8 NUTIII regions located in the North of Portugal. The results showed that a specific subregion–Area Metropolitan do Porto–concentrates both the tourism demand and supply in the years 2014 and 2017, despite the increasing values found for all the variables in the 8 subregions. When it is observed a decrease in the levels of concentration are the subregions near by the most concentrate one that increase the share of tourism demand and supply. More rural and less populated areas need more targeted and specific policies measures to attract even more visitors.

This paper considers a price-set competition between a nonprofit hotel and a for-profit hotel, in a differentiated service market, with uncertain demand. We compute the Bayesian-Nash equilibrium, and we analyse the effects of the degree of altruistic preference on market equilibrium outcomes. As a result, we get that as the nonprofit hotel values more the consumer surplus, both hotels set higher (resp., lower) prices, if the probability of higher demand is high (resp., low). Furthermore, the expected profit of the for-profit hotel decreases (resp., increases) with the degree of altruistic preference, for either low or high (resp., intermediate) values of this degree. The expectation of the objective function of the nonprofit hotel increases with the degree of altruistic preference.

In this age of globalized medicine, when international travel and access to online health information is easily accessible, medical tourism (MT) gains an important global perspective on health. Patients, in most countries around the world, are exercising crescent degrees of autonomy in their health care options, obtaining information from different sources from their regular health care providers and, in some cases, choosing to seek care alternatives outside of national health service. In Portugal MT, is still only in the early stages but is considered one of the strategic products for tourism development. This study aims to explore the existing information on MT in Portugal. Information plays a very important role in attracting medical tourism and Portugal’s ability to design and implement information networks is largely known. Proper medical information systems are one of the most important tools for attracting medical tourists. The analysis in this paper reveals that Portugal presents the necessary conditions to be a destination of MT, due to the infrastructures and the human resources that it has, but currently few people know this country for the practice of medical treatments. Although the MT is in the introductory phase of the market, already has mechanisms to meet demand, it is still necessary to position itself in the international market. It will be necessary to create an image of Portugal associated with tourism linked to health care, creating a branding and slogans to promote the MT.

Apesar de já existirem vários estudos relacionados à implementação da pedagogia da gamificação em ambientes nad educativos (Cruz & Orange, 2016), a verdade é que estudos relacionados à implementação da abordagem 'Escape Room' (Guigon, 2018) são ainda bastante escassos, no que concerne aos contextos de ensino. No entanto, têm-se realizado algumas experiências pelo que se torna necessário reetir sobre sua relevância na educação, com o fim de aprender sobre o seu desenho e os principais resultados e, ao mesmo tempo, orientar os professores para uma implementação adequada e bem-sucedida.

El español es un idioma plurinacional y multiénico que debe mucho de su éxito educativo tanto a la cohesión como a la diversidad de pautas pragmáticas de comunicación, sobretodo del español latinoamericano (Regueiro Rodríguez, 2016). Esta diversidad lingüística y cultural es resultado de los contactos históricos con las lenguas precolombinas, europeas y africanas, pero no impide la intercomprensión entre los distintos pueblos hispanohablantes. De hecho, nos parece pertinente trabajar las variedades lingüísticas y culturales del español latinoamericano (Moreno Fernández, 2000; Liceras, Carballo, y Droege, 1995; Beaven y Garrido, 2000), en la clase de español como lengua extranjera (ELE), teniendo en cuenta una pedagogía de los discursos, que involucra interactivamente a los sujetos en el análisis y producción de textos (Fonseca, 1992; Sueiro Justel, 2012). Asimismo, el principal objetivo de nuestro estudio es caracterizar lingüísticamente dichas variedades, que plasman el binomio cohesión-diversidad, recurriendo a discursos literarios e hipermedia con aportaciones de la sociolingüística histórica. Considerando esta heterogeneidad, plasmada en el binomio cohesión-diversidad, el principal objetivo de nuestro estudio es caracterizar lingüísticamente dichas variedades, recurriendo a discursos literarios e hipermedia con aportaciones de la sociolingüística histórica (Barros, 1997; Sueiro Justel, 2012). Nos proponemos además, a través de un estudio de caso (Benson, Chik, Gao, Huang, y Wang 2009) y con una perspectiva metodológica cualitativa, que incluye cuestionarios, notas de campo y pautas de evaluación de cursos de formación docente y manuales didácticos, concretar los siguientes propósitos: a) analizar las representaciones que los estudiantes y profesores tienen del estudio de estas variedades (Alvar, 2002) en instituciones de enseñanza superior en Portugal; b) evaluar su presencia en la formación de profesorado y en los manuales de ELE en Portugal; c) crear propuestas didácticas basadas en discursos literarios e hipermedia.
