- An ERP selection using a hybrid methodologyPublication . Ferreira, Fernanda A.; Pereira, TeresaWith this work, we developed a multi-criteria decision-making model to assess and select an Enterprise Resource Planning (ERP), using a multi-criteria decision analysis (MCDA). A hybrid multi-criteria methodology is used for the assessment and selection of an ERP, combining the MMASSI/IT methodology, which is used to both define the relevant family of criteria, based on their features and flexibility to change and adapt to a given scope, and the weight of criteria. Then, the well-known Analytic Hierarchy Process (AHP) methodology is used to perform the decision-makers’ value function elicitation preference of alternatives pairwise comparison in each criterion. The additive aggregation is used to compute the alternatives global score. The proposed hybrid model was validated in an industrial context by three Decision-makers.
- Comparison between different licensing schemes in a Stackelberg model when the follower is the innovatorPublication . Bode, Oana R.; Ferreira, Flávio; Ferreira, Fernanda A.In the present paper we consider a differentiated-good Stackelberg model, when the follower firm engages in an R&D process that gives an endogenous cost-reducing innovation. We assume that there can exist a technology transfer between innovator and non-innovator firm. The aim of this paper is three-fold: to do a comparison of the fixed-fee and royalty licensing cases, of the two-part tariff and royalty licensing cases, respectively of the two-part tariff and fixed-fee licensing cases, in order to state in which case is indicated for the innovator firm to license its technology. This comparison allows us to identify which licensing scheme is more profitable for the innovator (follower firm).
- Complexity constraint in the distributor’s pallet loading problemPublication . Barros, Hugo; Pereira, Teresa; Ramos, António G.; Ferreira, Fernanda A.This paper presents a study on the complexity of cargo arrangements in the pallet loading problem. Due to the diversity of perspectives that have been presented in the literature, complexity is one of the least studied practical constraints. In this work, we aim to refine and propose a new set of metrics to measure the complexity of an arrangement of cargo in a pallet. The parameters are validated using statistical methods, such as principal component analysis and multiple linear regression, using data retrieved from the company logistics. Our tests show that the number of boxes was the main variable responsible for explaining complexity in the pallet loading problem.
- Domestic and international price-setting mixed triopoliesPublication . Ferreira, Fernanda A.; Ferreira, FlávioWe will consider two models describing certain market structures: (i) a domestic market in which a public firm (whose objective is to maximize social welfare) competes with two private firms (whose objective is to maximize their own profits); and (ii) an international market in which a domestic public firm competes with one domestic private firm and one foreign private firm. In both situations, firms decide simultaneously the price for their substitutable goods. We compare the maximum-revenue tariff with the optimum-welfare tariff, and also the other output equilibria obtained in each case. Furthermore, we also compare the results in the domestic competition with the ones in the international competition.
- Entrepreneurs’ self-perception of skills in rural tourismPublication . Castro, Conceição; Ferreira, Fernanda A.The objective of this paper is to study the perception of entrepreneurial and personal maturity skills among owners of rural tourism businesses and structure these skills. The main obstacles to entrepreneurship felt by these entrepreneurs are also analysed. Using the results of a survey of rural tourism businesses in Northern Portugal, exploratory (EFA) and confirmatory factor analysis (CFA) were conducted. The data was evaluated through CFA, using Analysis of Moment Structure and performed a Structural Equation Model. The CFA led to two distinct factors: one includes emotional coping, critical evaluation and networking (personal maturity) skills, while the other (entrepreneurial) includes goal setting and environment scanning skills. The findings reveal, after a cluster analysis based on the resulting component scores, three different groups of entrepreneurs with different perception of competencies, background and type of business. The owners/managers encountered some restrictions in the start-up process as the bureaucracy and the lack of financial support and information. Studying rural tourism owner's perceived entrepreneurial competencies provide advances in identifying its dimensionality and corresponding profiles and help defining strategies to enhance them, in order to promote success and local development.

- Ethical behavior of firms and corruption in the public sector – a cluster analysis of worldwide countriesPublication . Castro, Conceição; Ferreira, Fernanda A.; Lopes, CristinaIn countries where corruption is high, there is less incentive for corporate organizations to behave ethically. Ethics, either in the private and public sectors, can be related to the level of economic development, economic freedom, and the quality of governance. The objective of this paper is to analyze the relationship between corporate ethics and corruption in the public sector, to group countries according to these indicators, and investigate the characteristics of these clusters. A hierarchical followed by a K-means cluster analysis was performed to group 127 countries. Non-parametric and post-hoc tests were used to examine the significant differences among clusters in some features. The correlation between the ethical behavior of firms and corruption in the public sector was strong and significant. The cluster analysis led to three significantly different clusters, one formed by countries with high levels of corporate ethics and low corruption and it is composed only by countries with high-income, another with medium levels and finally a group of countries with low levels of corporate ethics and high levels of corruption. The results also suggest significant differences among the clusters in several economic, institutional, and development indicators. Improving these indicators potentially lead to high standards of ethics in the private and public sectors.
- Information systems project success surveys - Insights from the last 30 yearsPublication . Loureiro, Elsa; Gomes, Bruna; Varajão, João; Silva, CândidaInformation Systems (IS) projects have a long history of negative reputation regarding their success. However, studies that report the success of IS projects are generally focused on software development (which is only one of the many types of IS projects). Furthermore, practically no research compares the success achieved in the different types of IS projects and projects from other areas. Aiming to contribute to filling this gap, this paper presents a critical review of surveys that report the success of IS projects and gives essential recommendations for further studies.
- Learning experiences in the culinary classroom: identifying barriers and enablers in the practical teaching-learning process in gastronomyPublication . Koerich, Guilherme Henrique; Ferreira, Fernanda A.; Silva, José António; Catapan, Araci HackGastronomy education is relatively new in the university environment. Practical classes in kitchen laboratories are strategic in development the segment. A practical class demands that students mobilize a wide range of skills, assimilate visual cues, information about products and utensils, and critical points of preparation, in a dynamic process in which, besides cooking, students must also practice teamwork, clean the space, manage several activities, and commit to the deadlines and objectives set by the teacher. There are several gaps highlighed in the literature regarding educational practices in hands-on cooking laboratories. Based on this premise, this research aimed to identify enablers and hindrances to hands-on learning in cooking classes, from the perspective of students, in a higher education institution in Portugal. To reach this goal, a structured questionnaire was applied to students of two higher education programmes in the area. Bardin’s content analysis model (2006) was used to analyze the results. The results indicate that the interaction between teachers and students in all stages of a practical class is fundamental for the success of the teaching-learning process.
- Licensing by fixed-fee and two-part tariff in a differentiated Stackelberg model when the follower is the innovatorPublication . Ferreira, Flávio; Bode, Oana R.In the present paper we consider a differentiated-good Stackelberg model, when the follower firm engages in an R & D process that gives an endogenous cost-reducing innovation. The aim is two-fold: the first is to study the case when there is a technology transfer between the innovator and the non-innovator firm based on a fixed-fee licensing contract, and the second is to study the case when there is a technology transfer between the innovator and the non-innovator firm based on a two-part tariff licensing contract. The main result of the paper is that the degree of the differentiation of the goods is the key factor in the decisions of the innovator firm, influencing its licensing strategy. In particular, we find that for the innovator firm is better a fixed-fee or a two-part tariff licensing contract than no-licensing, even if the innovation is drastic. In the case of a fixed-fee licensing, the main variables of this duopoly model increase with the differentiation of the goods all the time. It turns out that in the case of a two-part tariff licensing, this conclusion does not fit all the time. The findings of this paper extend the literature on contract auctions when the innovating firm has different options for licensing its innovation.
