- Bibliometric Analysis of Sustainable Indicators in AgribusinessPublication . Monteiro, Sónia; Quesado, Patrícia; Ribeiro, Verónica; Fernandes, Maria Eduarda; Eugénio, Teresa; Costa, João; Rodrigues, Hugo; Tomás, MarinaThe aim of this paper is to analyze the scientific production in the last decade (2011–2022) related to sustainable indicators (environmental, economic, social and ESG—Environmental, Social and Governance) in agribusiness. As methodology, a bibliometric study was carried out on articles from Scopus database. Afterwards, the most cited articles, journals and countries were analyzed, as well as a thematic analysis of the keywords. Results indicate that research on sustainable indi- cators of agribusiness has increased over time. In last years, the number of scientific papers on these topics has been increasing, probably associated with the approval of the United Nations for Sustainable Development (known as 2030 Agenda, approved in 2015). Italy is the country with most publications, the highest number of citations, and with the largest collaboration network. Most papers are published in 2 journals of higher impact and LCA (Life Cycle Assessment) is cited as the most usual method to assess the impact of business. Regarding the indicators to evaluate the sustain- ability of agribusiness, there is a greater predominance of environmental indicators compared to economic and social indicators.
- Tourism Destination Branding as a Marketing Factor: A Short Literature Review with a Focus on Northern CyprusPublication . Kudratova, Malika; Castanho, Rui Alexandre; Santos, EleonoraThis research aims to evaluate the effects of “branding” on client satisfaction and loyalty within the framework of marketing management studies. As a result, brand image and destination brand loyalty were used as two mediators to examine customer happiness and loyalty. The premise is that the success of the lodging industry (i.e., four-and five-star hotels) significantly impacts a destination’s profitable tourism sector. However, the lodging industry can succeed if there is a base of devoted and contented clients. A significant role in mediating this results is branding. Contextually, the study used the Northern Cyprus as a case to investigate and examine the elements that establish the island’s “brand” description and how much branding may be used as a marketing tool. The results show that customers’ contributions to the delivery and use of destination services do not have a beneficial impact on the brand image of the destination, nor does brand image serve as a mediator between customers’ contributions and destination brand loyalty. Regarding the clients’ willingness to get service with no input, this can be explained. Moreover, customer satisfaction is acknowledged as having a favorable impact on the perception of a location. The relationship between service quality and loyalty is consistent with earlier research. Service quality positively impacts customer satisfaction, albeit the findings were lower than anticipated.
- The Implementation of the Circular Economy R-Principles and Strategies: The Portuguese Hotel Industry PerspectivePublication . Costa, Berta; Rodrigues, Susana; Santos, NatáliaCircular Economy (CE) is a concept that has been gaining increasing importance in business circles and advocated by European Union, and by several governments worldwide. It is acknowledged that it has the potential to optimise resource efficiency, minimise production and consumption of greenhouse gas emissions, while simultaneously granting competitive advantage business prospects. Although it has been gaining momentum among academia, politicians, and practitioners, it is apparent some struggling when it comes to the design of a framework explaining how companies can embrace circularity and on how to adapt their business model to this new economic system. Despite its importance and applicability by the travel and tourism sector in general and the hotel industry in particular, it is insufficiently studied and examined. This empirical study investigates this concept on the Portuguese hotel industry perspective concerning the adoption of CE practices and CE R-principles through a survey instrument disseminated across the Portuguese hotel industry, with 78 valid responses. This article also introduces a new set of R-principles to the already existing ones, and contributes to the scientific research on the travel and tourism industry, and mainly to the one linked with the Portuguese hotel industry, which has been vaguely examined up to now. The results obtained indicate that these R-principles have been gaining importance, being adopted, and put into practice by the Portuguese hotel industry with special emphasis on the 3R-Principles (Reduce, Reuse, Recycle) along with Repair. Findings also indicate that some initiatives that are in line with a Circular Economy paradigm, namely recycling, reducing water and energy consumption, and cleaning management policies, towel and bed linen programmes, staff and education programmes, green products, certifications, among others, are also being considered.
- Sustainable tourism and the circular economy: A theoretical overviewPublication . Costa, Berta; Rodrigues, Susana; Moreno, PilarThe concept of sustainable tourism has become one of the most noteworthy topics among academics and practitioners and a hallmark in tourism discourse. During the last decades, tourism has developed into one of the largest socio-economic activities, and thus driving economic growth that most supports to the countries’ GDP (Gross Domestic Product). The world economic paradigm, and consequently the tourism industry, is configured according to the linear model of production and consumption, in which goods are discarded after usage, resulting in massive waste. Furthermore, the degrading impact of tourism, along with the assumption that natural resources are abounding, and that environment has unlimited means to absorb waste, need to be addressed without delay. Considering these premises, the principle of sustainable tourism arose with the objective of minimizing the negative effects of tourism related activities. From this standpoint, circular economy emerges as a solution, as it harmonizes economic development with the sustainable use of natural resources, and also enables the tourism industry to become more sustainable. The purpose of this article is to outline the conceptual dimensions of sustainable tourism and circular economy, and also scrutinize how these two constructs have evolved over the past decades and their correlation. A broad literature review was conducted, in order to draw attention to the constituent elements brought to discussion.
- Estimation of prevalence in rare disease using pooled samplesPublication . Martins, J. P.; Santos, R.; Felgueiras, M.The use of pooled samples for screening infected individuals is a known procedure to reduce costs. In an estimation problem, the aim is only to determine how many individuals are infected instead of determining who is infected (classification problem). In that setting, our goal was to compare the performance of using one or two-dimensional arrays. The best performance was established according to one of the following criteria: minimizing the number of individuals or the number of tests required to attain a certain estimate accuracy. It is observed that when we want to minimize the number of individuals used, the two-dimensional procedures have a little advantage over the one-dimensional procedures. However, when the major concern is the cost, the one-dimensional procedures clearly outperform the two-dimensional procedures.
- Alternative heavy tailed models in seismologyPublication . Felgueiras, Miguel; Martins, João; Santos, RuiGreat earthquakes are commonly considered as the ones with moment magnitude (Mw ) above or equal to 8.0. Since these earthquakes can destroy entire communities located near the epicentre, the search of physical laws that explain the energy released by them is an important issue. There is a connection between the radiated energy of an earthquake, its magnitude and its seismic moment (M 0). Thence, when fitting a heavy or an extremely heavy tailed distribution to a seismic moment dataset, we are in fact adjusting a mathematical model which explains the amount of energy released by these great seisms. Therefore, the main goal of this work is to study the more appropriated Pareto based models (the most used family in this field) when explaining the seismic moment of the great earthquakes. With this purpose in mind, we selected two different catalogs that accommodate recent events and are considered more accurate than other catalogs used in previous works. We conclude that the traditional Pareto distribution remains a good choice to deal with this kind of data, but Log-Pareto lead to higher p-values and Location-scale Pareto is better fitted to the biggest events.
