Opportunities for research on evaluation of seaport performance: A systemic analysis from international literature
2015
The purpose of this article is to analyze the opportunities for research on the theme evaluation of seaport performance through the investigation of a bibliographic portfolio of articles with scientific relevance. In order to reach this goal, the intervention tool used was ProKnow-C (Knowledge Development Process – Constructivist), which consists of a structured process for the generation of knowledge on a determined theme from the interests and limitations of the researcher, following a constructivist view and requiring a constant interaction between the researcher and the object of his research. The highlighted results are the identification of the main characteristics of the scientific …

The relationship between credit ratings and asset liquidity: Evidence from Western European banks
2020
This study examines the role of asset liquidity in Western European banks’ credit rating downgrades and upgrades over the 2005–2017 period. The results suggest that changes in bank credit ratings have been more favorable for banks that have a liquid asset portfolio. Furthermore, asset liquidity has a stronger effect on the credit rating of banks that already have an illiquid asset portfolio. In contrast, the effect is significantly smaller or nonexistent for the most liquid banks. These results imply that the new liquidity regulation introduced by the Basel III requirements will improve the stability and hence decrease the fragility of the European banking sector. Furthermore, the benefits …
A Unified Approach to Portfolio Optimization with Linear Transaction Costs
2004
In this paper we study the continuous time optimal portfolio selection problem for an investor with a finite horizon who maximizes expected utility of terminal wealth and faces transaction costs in the capital market. It is well known that, depending on a particular structure of transaction costs, such a problem is formulated and solved within either stochastic singular control or stochastic impulse control framework. In this paper we propose a unified framework, which generalizes the contemporary approaches and is capable to deal with any problem where transaction costs are a linear/piecewise-linear function of the volume of trade. We also discuss some methods for solving numerically the p…
Elever som flerspråkiga : åttondeklassisters språkportfolier och svenska språkets ställning i dem
2011
Tämä pro gradu-tutkielma keskittyy tutkimaan oppilaiden kokemuksellista monikielisyyttä sekä oppilaiden yksilöllisiä kielirepertuaareja. Tarkoituksena on tutkia oppilaita monikielisinä kielenkäyttäjinä sekä tutkia mitä kieliä ja kielimuotoja heidän kielirepertuaareihinsa lukeutuu. Tutkielma pyrkii vastaamaan myös siihen, millainen rooli koulussa opiskeltavilla kielillä oppilaiden elämässä on. Erityisesti kiinnostuksen kohteena toimii toisen kotimaisen kielen ruotsin asema ja oppilaiden suhtautuminen ruotsin kieleen. Oppilaiden oma kokemus on avaintekijänä ja tutkimus lähtee heidän näkökulmastaan ja kokemusmaailmastaan. Tutkimuksen painopiste on oppilaiden yksilöllisessä kokemuksellisuudessa…
A new project management approach for R&D software projects in the automotive industry - continuous V-model
2017
Most current work activities in R&D centres are innovative and dynamic, with project management acting as the discipline that governs them. The improvement of PM methods has become a necessity due to the following main factors: classical methodologies are increasingly difficult to apply, cutbacks in project duration are requested by organisations and customers, demands for product quality are continuously expanding. The paper examines how PM concepts are used in developed R&D projects, based on the V-model approach. It also introduces an enhanced new approach called Continuous V-model - CVM, based on agile concepts. The model has been applied on a real automotive R&D project and the resulte…
A Simulation Analysis of the Microstructure of an Order Driven Financial Market with Multiple Securities and Portfolio Choices
2005
In this paper we propose an artificial market where multiple risky assets are exchanged. Agents are constrained by the availability of resources and trade to adjust their portfolio according to an exogenously given target portfolio. We model the trading mechanism as a continuous auction order-driven market. Agents are heterogeneous in terms of desired target portfolio allocations, but they are homogeneous in terms of trading strategies. We investigate the role played by the trading mechanism in affecting the dynamics of prices, trading volume and volatility. We show that the institutional setting of a double auction market is sufficient to generate a non-normal distribution of price changes…
Versatile tool for competence management - an e-portfolio management system for higher education in applied sciences
2011
In the line of outcome based education and transferability of credits, we study a Higher Education case and propose an e-Portfolio solution as a versatile tool for assessment tasks. The solution tackles the problems firstly, of accreditation of prior achievements from both institutional and experiential learning. Secondly, the developed tool carries the process of learning outcome definitions management (derived from the real employment world), and the learner self-assessment and self-reflection as well as the guidance and support for these. The e-Portfolio management system, ePofo, supports the identification, assessment, recognition and accreditation of prior learning achievements and lea…
A fuzzy ranking strategy for portfolio selection applied to the Spanish stock market
2007
In this paper we present a fuzzy ranking procedure for the portfolio selection problem. The uncertainty on the returns of each portfolio is approximated by means of a trapezoidal fuzzy number. The expected return and risk of the portfolio are then characteristics of that fuzzy number. A rank index that accounts for both expected return and risk is defined, allowing the decision-maker to compare different portfolios. The paper ends with an application of that fuzzy ranking strategy to the Spanish stock market.
