- Cruise destination characteristics and performance Application of a conceptual model to North Atlantic islands of MacaronesiaPublication . Luz, Luís Machado; Antunes, António Pais; Caldeirinha, Vítor; Caballé-Valls, Jordi; Garcia-Alonso, LorenaThe purpose of this study is to develop a conceptual model for both port and cruise destinations composed by site and situation-related factors as the main drivers with a direct influence on the performance of the cruise destination. A moderator variable was also included on the model, due to the different characteristics that cruise ports at distinct levels of development present. The conceptual model was then applied on the North Atlantic archipelagos of the Macaronesia region through a survey aimed at cruise specialists and stakeholders. The results of a structural equation model confirmed the concept model, which was subsequently validated through several interviews to senior officials of cruise line operators. Significant differences were observed between the more developed ports of the region and the less developed ports . For the more developed ports, there is a shared influence of both site- and situation-related factors, while in the less developed ports the main drivers are mostly restricted to site-related factors.
- Green Shipping Effect on Sustainable Economy and Environmental Performance.Publication . Felício, J. Augusto; Rodrigues, Ricardo; Caldeirinha, VitorThis paper focuses on green shipping and its’ influence on the sustainable economy and environmental performance. Based on the green shipping approach, this empirical study examines a survey sample of 193 responses from Portuguese and Spanish executive managers and uses exploratory factor analysis and structural equation model. The Green shipping approach supports the green theory. The results show the importance of green efficiency, green management, and pollution impact. The confirmation of the sizeable influence of green shipping on the sustainable economy and environmental performance constructs constitutes a major contribution to the literature. Green management and green efficiency contribute to controlling the impact of pollution with practical effects on economic sustainability. Another contribution arises from the fact that tax and financial incentives and environmental sustainability regulations indicate the relevance of the pollution impact and sustainable economy.
- O Uso da Tecnologia da Informação na Inovação dos Sistemas Logísticos PortuáriosPublication . Caldeirinha, Vítor; Nabais, João LemosAs características dos Port Community Systems (PCS) afetam como a colaboração entre os players pode ser estabelecida na comunidade portuária. A digitalização feita em terminais no âmbito dos PCS tem fomentado o desenvolvimento da colaboração horizontal na comunidade portuária. O acesso a dados e informações relevantes cria oportunidades para novos modelos de negócios para a comunidade portuária. Através da análise realizada neste estudo, concluímos que a implementação de uma Internet Física pode levar décadas, mas a mudança nos serviços prestados pelo PCS está configurando uma mudança de mentalidade de Cadeias de Abastecimento Isoladas para Cadeias de Abastecimento Abertas, promovendo a Internet Física.
- Port Community Systems: Accelerating the Transition of Seaports toward the Physical Internet - The Portuguese CasePublication . Caldeirinha, Vítor; Nabais, João Lemos; Pinto, CláudioSupply chains are complex systems that have grown in dimension and spread worldwide. In supply chains, physical and information flows have strict service quality requirements, namely transparency conditions and traceability. Seaports, connecting land and maritime transport, are special components of supply chains where multiple players interact with different perspectives, and conflicting goals may arise. Port community authorities invest in electronic platforms to foster communication and integration with the companies that interact with the seaport, guiding the digitization of the seaport business. In main European and world ports, the Port Community System (PCS) is the platform that supports the creation of a network composed of shipping agents, shippers, freight forwarders, transporters, terminals, logistics platforms, and public entities. PCS focuses on service level, partner networks, maritime services, freight services, logistical services, and advanced port services. These features have an impact on seaport operations, which affects supply chain performance. Digitization within the scope of the PCSs has fostered the development of horizontal collaboration between seaport community partners. The Physical Internet (PI) is an innovative concept that seeks new logistics solutions requiring integration and interoperability between partners in the supply chain, including maritime and land transport. This paper focuses on (i) the evolution guidelines of PCSs and (ii) on the PCS Business Factors that can drive the supply chain into a significant improvement in performance. A survey was sent to a sample of Portuguese supply chain experts regarding the causal relationship between PCS Business Factors and supply chain performance in the next 10 to 20 years. From the data collected, recent services evolving at PCS are promoting a mindset change aligned to the implementation of a Physical Internet. Establishing a Physical Internal in Portuguese seaports could take decades, but it will support the transition to a new phase of PCS, accelerating the transition from Isolated Supply Chains (I-SCs) to Open Supply Chains (O-SCs), thus improving supply chain performance.
- The Impact of Port Community Systems (PCS) Characteristics on PerformancePublication . Caldeirinha, V.; Felício, J. A.; Salvador, A.; Nabais, J.; Pinho, T.The purpose of this study is to assess the effect of the port community system (PCS) and its influence on port performance. The techniques of principal component analysis and structural equation modelling are applied to 153 valid responses from a sample, obtained from Portuguese port community experts. The results identify and measure the factors that characterize the PCS and affects port performance. PCS characteristic, including service level, partner network, ship services, cargo services, logistics services and advanced services, affect port per formance, defined as operational performance, effectiveness and efficiency. The primary contribution of this study is to show the mechanisms that allow ports to adjust and evolve the PCS characteristics and develop new features that affect port performance.
- Ambidextrous capacity in small and medium-sized enterprises.Publication . Felício, J. Augusto; Caldeirinha, Vítor; Dutra, AdemarThis study examines the ambidextrous capacity—the ability to respond simultaneously to both disruptive and incremental innovation processes—of small and medium-sized enterprises (SMEs) in Portugal. The purpose is to understand the organizational ambidexterity of SMEs and its relationship to organizational performance and innovation capacity. The objectives are to evaluate the characteristics that identify ambidextrous organizations and analyze the effect of organizational ambidexterity on performance, supported by the contingency-based approach, organizational theory, behavioral theory of the firm, and organizational learning theory. After factor analysis is performed, a structural equations model is used to analyze a sample of 202 valid responses. The analysis shows that, for SMEs, disruptive innovation factors relate mainly to innovation capacity and incremental innovation factors relate to organizational performance. The confirmation of organizational ambidexterity in SMEs and the increased recognition of the importance of disruptive innovation are relevant contributions to the literature.
- The nexus between port governance and performancePublication . Caldeirinha, Victor; Felício, J. A.; Cunha, S.; Luz, L. M.The diversity of port governance models in the world, sometimes even within the same country, has aroused the interest of researchers. This study is based on contingency theory to support the port governance model. The purpose is to understand the port governance model and the relation with port performance. There are three objectives: to analyze the port governance mechanisms; to analyze the port performance factors; and to understand the influence of the governance model mechanisms on port performance. A factorial analysis was used to determine the main components, and the methodology of the structural equation model was used to analyze a survey sample of 105 valid responses from specialists and managers of port user’s companies that operate in the main Portuguese ports. This study demonstrates that port governancemodel influences directly the port performance. The main contribution of this paper to the literature is providing a set of factors that public managers may decide when changing the characteristics of the port governance models to ensure their performance. It was also observed the approximation of the port expert vision of port governance with models described in literature.
- Government policies and portuguese port governance in the period from 2005 to 2015Publication . Caldeirinha, Victor; Felício, J. A.; Cunha, S.This research focuses on the effect of Portuguese government policies in port management, port strategy and port performance in the period from 2005 to 2015. With the structural equation modeling, we analyzed a sample of 172 observations. Government policies influence the port sector differently. The policies adopted during the period under study produced different effects, especially the national planning policies for investments as well as the central control policy, implemented to make operations and port labor more productive. The main contribution of this paper resides in understanding that it is essential to ensure sustainability conditions for the national port system in an increasingly globalized market where the trend is to be less dependent on the government policies.
- Sustainable tourism financial feasibility: a case study in Timor-Leste.Publication . Ferreira de Matos, AldaRecent research points out the importance of diaspora in the tourism sector and the shift happening in the tourism business model in insular countries. Lately, the demand for the niche of ecocultural tourism has been increasing, while the appearance of new construction techniques has powered the appearance of tourism facilities dierent from traditional hotels. An example of this phenomenon is Timor-Leste, where local authorities encourage tourism development to be on small sustainable facilities, the so-called boutique hotels. Nevertheless, the relevant literature does not address the nancial feasibility of this type of tourism facility. Following the expectations of national Timorese authorities regarding the type of facilities to be installed in their territory, a case study on a boutique facility project is presented in this paper. Using a discounted cash ow valuation model this case study's Net Income would be positive at the end of the 5th year of activity, when the break-even occurs, even considering small scale and ensuring environment protection exigencies.
- Ordinary differential equations with point interactions: An inverse problemaPublication . Dias, N.C.; C., Jorge; Prata, J.N.We study a class of linear ordinary differential equations (ODEs) with distributional coefficients. These equations are defined using an intrinsic multiplicative product of Schwartz distributions which is an extension of the Hörmander product of distributions with nonintersecting singular supports (Hörmander in The analysis of linear partial differential operators I, Springer, Berlin, 1983). We provide a regularization procedure for these ODEs and prove an existence and uniqueness theorem for their solutions. We also determine the conditions for which the solutions are regular and distributional. These results are used to study the Euler–Bernoulli beam equation with discontinuous and singular coefficients. This problem was addressed in the past using intrinsic products (under some restrictive conditions) and the Colombeau formalism (in the general case). Here we present a new intrinsic formulation that is simpler and more general. As an application, the case of a non-uniform static beam displaying structural cracks is discussed in some detail.
