    Academic Misconduct in Portugal: Results from a Large Scale Survey to University Economics/Business Students
    ( 2010) Aurora Teixeira ; Maria de Fátima Rocha
    The phenomenon of cheating in higher education is of overwhelming importance in that the students engaging in these acts are unlikely to have the skills necessary for their future professional life. Despite its relevance, the empirical evaluation of cheating in universities has been almost exclusively focused on the US context. Little is known about cheating at the European level, let alone in Portugal. Even less is explored at the regional level. In this paper we present evidence on the perception of cheating by Portuguese undergraduate students of economics/business degrees. We undertake a large-scale survey, involving 2675 students from all Portuguese mainland public universities (10). We found that copying-favourable environments are associated with a higher propensity to cheat. Moreover, in universities where 'codes of honour' exist, this propensity tends to be lower. Finally, the propensity to copy seems to be highly influenced by the cultural systems and socially-related factors of different regions.

    Accessibility levels of Portuguese enterprise websites: equal opportunities for all?
    ( 2012) Manuel Au-Yong Oliveira ; José Martins ; Jorge Pereira ; João José Ferreira ; Ramiro Gonçalves
    Web accessibility is growing in importance. We may also find an increasing need for access to web resources by those with some sort of disability. The Web is very important for spreading information and for promoting interaction between the various elements in society. Given this, it is essential that the Web presents itself as a totally accessible resource, so that it can help citizens with disabilities and their integration in society. This obligation should be even greater for enterprises as primarily the Web is used as a marketing and business platform. With this document, we present indicators regarding the [lack of] accessibility levels of Portuguese enterprise websites. This article contains theoretical and background considerations as well as the results of two different studies that the research team undertook. First of all, the research team made a comparison between the 1000 largest Portuguese enterprises (annual sales volume) and the 1000 best Portuguese small and medium enterprises (sales growth and profit) using a specialised software tool and according to Web Content Accessibility Guidelines (WCAG) 1.0; the research team then also considered WCAG 2.0 and its impact on enterprise Web accessibility. In the second study (qualitative in nature), focus group interactions led to a set of recommendations towards greater accessibility.

    Are finance, management, and marketing autonomous fields of scientific research? An analysis based on journal citations
    ( 2010) Pedro C. Vieira ; Aurora Teixeira
    Although there is considerable consensus that Finance, Management and Marketing are 'science', some debate remains with regard to whether these three areas comprise autonomous, organized and settled scientific fields of research. In this paper we aim to explore this issue by analyzing the occurrence of citations in the top-ranked journals in the areas of Finance, Management, and Marketing. We put forward a modified version of the model of science as a network, proposed by Klamer and Van Dalen (J Econ Methodol 9(2):289-315, 2002), and conclude that Finance is a 'Relatively autonomous, organized and settled field of research', whereas Management and (to a larger extent) Marketing are relatively non-autonomous and hybrid fields of research'. Complementary analysis based on sub-discipline rankings using the recursive methodology of Liebowitz and Palmer (J Econ Lit 22:77-88, 1984) confirms the results. In conclusions we briefly discuss the pertinence of Whitley's (The intellectual and social organization of the sciences, 1984) theory for explaining cultural differences across these sub-disciplines based on its dimensions of scholarly practices, 'mutual dependency' and 'task uncertainty'.

    A bibliometric account of Chinese economics research through the lens of the China Economic Review
    ( 2012) Aurora Teixeira ; Yuxin Du
    Very few studies on the assessment and evolution of Chinese economics research draw on quantitative methods, namely bibliometrics. Bibliometrics is a powerful tool that helps to explore, organize and analyze large amounts of information in a quantitative manner. Selecting the most important economic journal focusing on the Chinese economy - the China Economic Review (CER) - we classified and assessed all the (512) articles that have been published in CER from its founding (1989) to December 2010. Based on these articles, and undertaking an exploratory statistical analysis on three databases - a 'bibliographic' database (512 articles), a 'roots' database (over 10 thousand citations), and an 'influence' database (over 3 thousand citations), we concluded that: 1) 'Economic Development, Technological Change, and Growth'; 'Economic Systems', and 'International economics' are the most important topics for Chinese economics literature; 2) there is a trend in Chinese economics research for gro

    A bibliometric account of the evolution of EE in the last two decades Is ecological economics (becoming) a post-normal science?
    ( 2011) Manuela Castro e Silva ; Aurora Teixeira
    In ecological economics the debate on formalism and formalization has been addressed in the context of a lively discussion on ecological economics as a 'post-normal' (versus 'normal') science. Using ecological economics (EE) as a 'seed' journal and applying bibliometric techniques to all (2533) the articles published in EE from January 1989 to December 2009,we analyze the evolution of the field of ecological economics aiming to shed light on this debate. We observe the predominance (and increased relevance) of certain research topics: 'Methodological issues', 'Policies, governance and institutions' and 'Valuation'.Moreover, 'Collective action', 'Technical change and the environment' and 'Values' stand as emergent themes of research. Finally, we note that ecological economics experienced an 'empirical turn' reflected in a shift away fromexclusively formalized papers towards exclusively empirical and, to a larger extent, 'formal and empirical' ones. The combination of the prominent and emergent topics and the 'empirical turn' mirrors the increasing awareness among researchers in the field of the need to address a key specificity of ecological economics - the interdependence of the economic, biophysical and social spheres. On this basis, we argue that at least through the lens of EE, ecological economics has evolved towards a post-normal science.

    A bibliometric portrait of the evolution, scientific roots and influence of the literature on University-Industry links
    ( 2012) Luisa Mota ; Aurora Teixeira
    The study of university-industry (U-I) relations has been the focus of growing interest in the literature. However, to date, a quantitative overview of the existing literature in this field has yet to be accomplished. This study intends to fill this gap through the use of bibliometric techniques. By using three different yet interrelated databases-a database containing the articles published on U-I links, which encompass 534 articles published between 1986 and 2011; a 'roots' database, which encompasses over 20,000 references to the articles published on U-I relations; and a 'influences' database which includes more than 15,000 studies that cited the articles published on U-I relations-we obtained the following results: (1) 'Academic spin offs', 'Scientific and technological policies' and (to a greater extent) 'Knowledge Transfer Channels' are topics in decline; (2) 'Characteristics of universities, firms and scientists', along with 'Regional spillovers', show remarkable growth, and 'M

    Business Model Generation: A handbook for visionaries, game changers and challengers
    ( 2011) Manuel Au-Yong Oliveira ; João José Ferreira
    The book entitled 'Business Model Generation: A Handbook for visionaries, game changers and challengers' though written by Osterwalder and Pigneur (2010) was also co-created by 470 practitioners from 45 countries. The book is thus a good example of how a global creative collaboration effort can contribute positively to the business and management literature and subsequently to the advancement of society (Alam and Hoque, 2010; Alam et al., 2010a, b). Consisting of five main chapters (Canvas, Patterns, Design, Strategy and Process) and two additional chapters Outlook and Afterword, 'Business Model Generation' should be read by those motivated to 'defy outmoded business models and design tomorrow's enterprises' (front cover).

    Business Narrative Modelling Language (BNML) representations: A storyline view and a plot view of how interoperability is an antecedent of innovation at IP BRICK
    ( 2012) Manuel Au-Yong Oliveira ; João José Ferreira
    The relationship between interoperability and innovation is very hard to prove and more empirical studies seem to be needed to this end. We performed an in-depth case study at an innovative Portuguese software firm which has achieved steady growth, international brand recognition and consistent annual profits, despite the much publicized economic crisis in Portugal. IP BRICK is interesting as it differs from the survivalist entrepreneurial endeavours which tend to be the norm in Portugal. We indeed conclude that having an interoperability capability is central and an antecedent to innovation. Furthermore, a dynamic organizational innovation culture is instrumental and Information and Communication Technology (ICT) is seen to be an enabler in the process. Using digital knowledge management tools as a basis for innovation and having a company-wide profit-sharing scheme based on seniority, but also on merit, encourage a knowledge-sharing corporate culture. This is seen to be especially im

    Cheating by Economics and Business Undergraduate Students. An Exploratory International Assessment
    ( 2010) Aurora Teixeira ; Maria de Fátima Rocha
    Today's economics and business students are expected to be our future business people and potentially the economic leaders and politicians of tomorrow. Thus, their beliefs and practices are liable to affect the definition of acceptable economics and business ethics. The empirical evaluation of the phenomenon of cheating in academia has almost exclusively focused on the US context, and non-US studies usually only cover a narrow range of countries. This paper presents a comprehensive, cross-country study on the magnitude and determinants of cheating among economics and business undergraduates, involving 7,213 students enrolled in 42 universities located in 21 countries from the American (4), European (14), Africa (2) and Oceania (1) Continents. We found that the average magnitude of copying among economics and business undergraduates is quite high (62%) but there was significant cross-country heterogeneity. The probability of cheating is significantly lower in students enrolled in schools located in the Scandinavian, and the US and British Isles blocks when compared with their Southern European counterparts; quite surprisingly this probability is also lower for the African block. On a distinctly different level, however, students enrolled in schools in Western and especially Eastern European countries reveal statistically significant higher propensities towards committing academic fraud.

    Cohesive fire management within an uncertain environment: A review of risk handling and decision support systems
    ( 2015) Abilio Pereira Pacheco ; João Claro ; Fernandes,PM ; de Neufville,R ; Oliveira,TM ; Borges,JG ; José Coelho Rodrigues
    Wildfire management has been struggling in recent years with escalating devastation, expenditures, and complexity. Given the copious factors involved and the complexity of their interactions, uncertainty in the outcomes is a prominent feature of wildfire management strategies, at both policy and operational levels. Improvements in risk handling and in risk-based decision support tools have therefore a key role in addressing these challenges. In this paper, we review key systems created to support wildfire management decision-making at different levels and scales, and describe their evolution from an initial focus on landscape-level fire growth simulation and burn probability assessment, to the incorporation of exposure and economic loss potential (allowing the translation of ignition likelihood, fire environment terrain, fuels, and weather and suppression efficacy into potential fire effects), the integration with forest management and planning, and more recently, to developments in the assessment of values at risk, including real-time assessment. This evolution is linked to a progressive widening of the scope of usage of these systems, from an initial more limited application to risk assessment, to the subsequent inclusion of functionality enabling their Utilization in the context of risk management, and more recently, to their explicit casting in the broader societal context of risks and decisions, from a risk governance perspective. This joint evolution can be seen as the result of a simultaneous pull from methodological progresses in risk handling, and push from technological progress in wildfire management decision support tool, as well as more broadly in computational power. We identify the key benefits and challenges in the development and adoption of these systems, as well as future plausible research trends.

    Corruption and MNCs' entry mode. An empirical econometric study of Portuguese firms investing in PALOPs
    ( 2011) Marlene Vidal Grande ; Aurora Teixeira
    Extant literature on FDI entry modes and corruption tend to convey the idea that corruption leads to the choice of low equity, i.e. joint‐ventures with local partners, or non‐equity modes, namely export and contracting, in order to avoid the contact with corrupt state officials. Recently, however, Demirbag et al. (2010) argument that, despite corruption, linguistic and historical ties between home and host countries guide MNCs to prefer high equity modes (namely, whollyowned subsidiaries). Focusing on a rather unexplored setting, the African countries, most specifically the PALOP (Países Africanos de Língua Oficial Portuguesa), which includes countries with both very high (Equatorial Guinea, Guinea‐Bissau, and Angola), high (Mozambique, São Tome and Principe) and middle (Cape Verde) levels of corruption, and that maintain quite close linguistic and historical ties with Portugal, we aim at testing Dermirbag's argumentation; in particular, we aim at assessing the extent to which PALOP's

    Digital forgetting in information-centric networks-the CONVERGENCE perspective
    ( 2014) Fernando Luís Almeida ; Hélder Fernandes Castro ; Maria Teresa Andrade ; Tropea,G ; Melazzi,NB ; Signorello,S ; Mousas,A ; Anadiotis,A ; Kaklamani,D ; Venieris,I ; Minelli,S ; Difino,A
    The Web is rapidly becoming the prime medium for human socialization. As it evolves towards an information-centric operation, it records everything and forgets nothing, assuming that every online resource disclosed by people (photos, posts, multimedia files, etc.) is permanently valid and is to be stored forever. However, throughout their lives, people tend to change, both in their habits as well as in their views and opinions. In many situations, as the years go by, information released loses relevance or people may decide they no longer want others to access information they have previously published. The work presented in this paper strives for a new information persistence paradigm, whereby the enforcement of "digital forgetting" is implemented over an information-centric model for the Internet. The defined solution enables the definitive elimination of digital objects, either on-demand or on a pre-scheduled basis, and, hence, their "forgetting." The solution, conceived within the framework of the European project CONVERGENCE, is based on the employment of metadata descriptions about resources, which unambiguously identify their rightful owners. This additional data is efficiently bound to the resource through the use of an extended version of the MPEG-21 Digital Item specification, and its prescriptions are enforced by CONVERGENCE's distributed provisions.

    Does structure influence growth? A panel data econometric assessment of 'relatively less developed' countries, 1979-2003
    ( 2011) Ester G. Silva ; Aurora Teixeira
    Neo-Schumpeterian streams of research emphasize the close relationship between changes in economic structure in favor of high-skill and high-tech branches and rapid economic growth. They identify the emergence of a new technological paradigm in the 1970s, strongly based on the application of information and communication technologies (ICTs), arguing that in such periods of transition and emergence of new techno-economic paradigms, the intermediate development countries and the countries which are not at the technological frontier have higher opportunities to catch-up. Although this debate is theoretically well documented, the empirics seem to lag behind the theory. In this article, we contribute to this literature by adding enlightening evidence on the issue. More precisely, we relate the growth experiences of countries which had relatively similar economic structures in the late 1970s, with changes occurring in these countries' structures between 1979 and 2003. The results reveal a robust relationship between structure and (labor) productivity growth, and lend support to the view that producing (though not user) ICT-related industries are strategic branches of economic activity.

    Drivers, processes and consequences of financial innovation: a research agenda
    ( 2012) Marko Torkkeli ; Anne-Laure Mention
    It is self-evident that financial innovation is a key player in the contemporary economy. However, its significant importance has largely been overlooked in innovation studies. To fill up this gap, and through an interdisciplinary approach, this article details a research agenda for innovation in financial services. It reviews the 'what', 'why' and 'how' of financial innovation in order to clarify all the ambiguities surrounding its nature, creation, purpose and impact. Specifically, the article investigates its definition and distinguishing features, its key determinants, its supporting processes, and finally its effects, mainly at firm-level. Therefore, the article opens the black box of financial innovation and uncovers its peculiarities in order to understand how it occurs when innovation is considered both as an 'outcome' of financial innovation and a 'process' supporting its creation.

    Entry mode choices of MNCs and host countries' corruption: A review
    ( 2012) Marlene Grande ; Aurora Teixeira
    Despite voluminous literature on corruption and the entry mode choices of multinational companies (MNCs) in isolation, a comprehensive account which details the mechanisms through which host country corruption impacts on MNCs' entry modes is lacking. To overcome such a gap, we systematically review and provide an up-to-date overview of the empirical literature on corruption and the entry mode choices of MNCs. The review demonstrates that, in general, when in presence of markets with high levels of corruption, MNCs prefer low equity (that is, joint-ventures with local partners) or non-equity (namely exports and contracting) entry mode choices. Nevertheless, it also reveals that, in some specific cases, such as cultural proximity, even when there is pervasive corruption, MNCs may enter via wholly-owned subsidiaries. Such conclusions uncovered an interesting path for future research by exploring a rather neglected context, where the entry mode choices of MNCs are made from developed count
