Assessing the drivers of virtual knowledge management impact in European Firm’s performance : an exploratory analysis

E-Business is a phenomenon that has progressed over the past decades at record speed, with considerable promise and hype. It has been embraced with varying degrees of enthusiasm and impact by both large firms and Small and Medium Enterprises (SME). Parallel with its development, E-Business has attracted research interests, seen in a plethora of new modules, programmes, models and tools. Knowledge Management (KM) is one tool that seams to gain a more relevant role, especially as managing knowledge has become increasingly important to all companies. Appropriate KM practices within organisations can be seen as one of the prerequisites to the enhancement of continuous performance improvement in the interne-based context. Thus, our aim is to develop a conceptual framework related to KM practices in a virtual context and to identify the nature of the relationship existing in those knowledge-driven elements and performance achievements. This paper aims to bridge the gap between the KM and e-business performance-related literatures from the viewpoint of European firms by establishing a model tested in European companies. For this purpose, we used a structural equation modelling analysis. The results show that KM has a positive impact on the maximization of e-business performance and that some elements individually have a positive influence on e-business performance. As limitations of the study, we consider the need for more research into this field and the inclusion of news elements such as technological readiness and management support to KM initiatives. The present study advances knowledge on the nature of the relative importance of different components of Internet-based KM as drivers of e-business performance and reinforces its importance as an integrated e-business tool.info:eu-repo/semantics/publishedVersio

Knowledge management : critical perspectives on e-business activities

This article is both a review and an agenda-setting piece. It argues that knowledge management suffers from conceptual and definitional ambiguity, oversimplification of its development processes, and methodological limitations. Nevertheless, there is a consensus in business and academia that knowledge is a key component of success and allows firms to achieve and sustains competitive advantages. In a digital era, these advantages arise from the potential of data and information that can be gathered, processed, shared, and used to improve e-business activities. Thus, this research bridges the gap in the assessment of knowledge management and e-business relationship, by applying an SEM to a large database sample of KM activities performed by European firms.N/

Internet sales as a new mode of internationalization

The way that organizations explore the Internet has been the focus of a substantial body of scientific studies and non-academic reflection. The main goal of this study is to analyze the potential of the internet as a mode of internationalization and the factors that influence the results of the adoption of this mean to access foreign markets. For this purpose, we examine the determinants of the level of international sales made via internet estimating an ordered probit model. The results show that the importance of previous experience in using the internet and developing international activity, together with the level of internet marketing budget , the level of investment on internet sophistication, the firm dimension, the business age and the type pf activity are variables that determine the results obtain in the international sales trough the internet.info:eu-repo/semantics/publishedVersio

Using Cost Observation to Regulate Bureaucratic Firms

We study regulation of a bureaucratic provider of a public good in the presence of moral hazard and adverse selection. By bureaucratic we mean that it values output in itself, and not only profit. Three different financing systems are studied - cost reimbursement, prospective payment, and the optimal contract. In all cases, the output level increases with the bureaucratic bias. We find that the optimal contract is linear in cost (fixed payment plus partial cost-reimbursement). A stronger preference for high output reduces the tendency of the firm to announce a high cost (adverse selection), allowing a more powered incentive scheme (a lower fraction of the costs is reimbursed), which alleviates the problem of moral hazard.Procurement, Regulation, Adverse selection, Moral hazard, Bureaucracy

O terrorismo e a transformação do planeamento estratégico de segurança nacional dos EUA

Este artigo faz a associação entre o Terrorismo Transnacional e a transformação que se vem verificando no planeamento estratégico de segurança nacional dos EUA desde o 11 de Setembro. O autor começa por caracterizar o planeamento estratégico americano, descrevendo os objectivos de cada um dos doze documentos analisados. Identifica, ainda, a hierarquia entre os diferentes documentos e a sua evolução em termos de pensamento estratégico. Justifica depois a relação entre o combate ao Terrorismo Transnacional e a transformação no planeamento estratégico dos EUA (como “detonador”, como “denominador comum” e como “capital” das opções políticas e estratégicas), que deu lugar à multiplicação de novas estratégias nacionais de cariz pragmático, funcional e conjuntural. Termina com considerações finais em que destaca a importância das estratégias nacionais americanas como instrumento de comunicação, de coordenação e de maior ligação entre vários actores, mas também como instrumento de acção e dissuasão de uma “Nação em Guerra”

A cultura de segurança e defesa no ensino superior em Portugal

O presente artigo tem como objectivo apresentar um ponto da situação sobre a “Cultura de Segurança e Defesa” no Ensino Superior em Portugal e, na mesma linha, contribuir com alguns subsídios para o seu desenvolvimento, numa altura em que novos desafios se colocam ao Estado e ao Cidadão, no que concerne à Segurança e Defesa. No sentido de consolidar as suas propostas, o autor começa por clarificar alguns conceitos, nomeadamente o de “Cultura de Segurança e Defesa”, para depois destacar a importância da formação moral e intelectual dos futuros quadros superiores da Nação, em especial depois do fim da conscrição nas Forças Armadas. As suas propostas, assentes num “Plano Director de Cultura de Segurança e Defesa”, a implementar pelo IDN na sequência do Programa do XVII Governo, são apresentadas de modo integrado em três áreas de intervenção, como a curricular, a organizativa e a comunitária. Está presente em todo o artigo, a ideia de que vale a pena investir nos jovens universitários, como factor multiplicador de valores e comportamentos, “pressuposto” que o autor considera indispensável para a acção de todos os actores mais ou menos directamente responsáveis pela “Cultura de Segurança e Defesa” em Portugal

Tourism development potential in an insular territory : the case of Ribeira Grande in the Azores

The Autonomous Region of the Azores is one of the most sustainable destinations in the world. Being an archipelago comprised of nine small islands, quality and sustainability are critical features in the tourism sector, inducing the need for thorough and technical strategic development processes. Ribeira Grande is an important municipality in the Azores, which envisioned tourism as a strategic sector to develop when the partial liberalization of the air passenger transport sector occurred in 2015. However, this destination had little tourism maturity and competitiveness and required some structural planning work. The development of a strategic plan for tourism for the municipality of Ribeira Grande, including the selection of tourism products, is explained in detail in this article, which highlights the main challenges and results of the process.N/

Wages and Job Satisfaction in Portugal

The interest in the analysis of job satisfaction has increased among economists. Indeed, reported levels of satisfaction have been seen as a good predictor of individual behaviour such as job turnover, productivity and absenteeism. Because of this, several studies have tried to identify the determinants of job satisfaction. This paper is concerned with job satisfaction in Portugal. For this purpose, we use the first six waves of the European Household Panel Data (ECHP). The panel nature of the data allows us to use a random effects estimator in order to control for unobservable individual heterogeneity. The results indicate that wages matter for job satisfaction but do not tell the whole story. In particular, having a good health status, a permanent contract and working the public sector influences positively the level satisfaction. We also find a great heterogeneity in satisfaction by regions, even in a small country as Portugal. These findings are valid for overall job satisfaction as well as for satisfaction with specific job domains such as pay, security, type of work and hours worked. Key words: job satisfaction, wages, regions, unobserved heterogeneity JEL Code: J28

Fault activity studies in the Lower Tagus valley and Lisbon region using geophysical data

he Metropolitan Area of Lisbon and the Lower Tagus Valley (LTV) region are located in central Portugal and inhabited by nearly 4 million people. The region has suffered throughout its history the effect of destructive earthquakes caused by hidden faults, possibly related to the plate boundary, which is sited approximately 400 km south of the region (Figure 1). In spite of low slip-rates and big recurrence times that have been estimated for these local, regional faults, they can produce moderate-to-large earthquakes that cause large damage and loss of life, as in 1344, 1531, or 1909 (e.g. Justo and Salwa, 1998; Cabral et al., 2003; 2013). The shorter occurrence time of the earthquakes might be owing to the existence of multiple active faults and/or time clustering owing to stress drop caused by proximal faults (e.g. Carvalho et al., 2006). Therefore, the seismic hazard and risk evaluation of the region has long been a reason of concern. Geological outcrop and geomorphologic mapping identified several regional faults in the LTV region that could be the source the historical earthquakes, but some of them do not affect. Quaternary sediments and lacked the proofs that they were active faults. On the other side, in the vast quaternary alluvial plains that cover the region, it was difficult to identify active faults, as the sedimentation/erosion rates erase any possible surface rupture caused by the low slip-rate faults (<0,35 mm/y). By the late-20th century, seismic reflection data that had been acquired for the oil-industry till the beginning of the 1980s began to be used to identify the major hidden fault zones (e.g. Cabral et al., 2003; Vilanova and Fonseca, 2004; Carvalho et al., 2006). Potential field data was also used to locate active faults in the areas where no seismic data is available (Carvalho et al., 2008; 2011). Though a few more active faults have been proposed, the vast majority of authors agree that the following active faults threaten the region: Nazaré-Caldas da Rainha, Lower Tagus Valley, Ota, Azambuja, Vila Franca de Xira (VFX), Pinhal Novo and Porto Alto faults (Garcia-Mayordomo et al., 2012; Vilanova et al., 2014). In this work, we discuss the acquisition, processing and interpretation of near surface geophysical works carried out over three of these faults — the VFX, Porto Alto and Azambuja faults — in order to confirm they have had activity during the Holoceneera. Their location is shown in Figure 2. We further estimate some of its fault parameters (vertical displacement, slip-rate, length, etc.) and respective implications in terms of seismic hazard

Regulating a monopolist with unknown bureaucratic tendencies

We determine the optimal contract for the regulation of a bureaucratic firm in the case in which the bureaucratic bias is firm's private information. We find that output is distorted upward when the bureaucratic bias is low, downward when it is high, and equals a reference output when it is intermediate (in this case, the participation constraint is binding). We also determine an endogenous reference output (equal to the expected output, which depends on the reference output), and find that the response of output to cost is null in the short-run (in which the reference output is fixed) whenever the managers' types are in the intermediate range and negative in the long-run (after the adjustment of the reference output to equal expected output).Procurement, Regulation, Adverse selection, Bureaucracy, Reservation utility
