Dividends and their distribution decisions, being a component of the compensation of investors are a constant financial worry within companies, thus revealing one of the themes highlighted in the context of the financial literature. Study will address the factors determining the dividend policy practiced by companies listed in the Portuguese stock market. The latter will be 47 non-financial companies listed on the Euronext Lisbon during 2009 until 2011. The two samples that have been investigated include the representative of the majority of non-financial companies listed on Euronext Lisbon and the other financial companies members of the PSI 20. The methodology adopted is one of the ordinary least squares regression and the amount of dividends per share distributed was used in determining the dependent variable. In relation to the independent variables, six explanatory factors were chosen. These include profitability, stability of dividend policy, size, growth, risk and investment opportunities. The conclusion suggests that the most important factors to explain the amount of dividends distributed are profitability and stability of dividend policy. There after, growth and risk factors, as well as factors that explain the amount of dividends distributed are also relevant. The remaining variables obtained were insufficient evidence pointing to a significant effect in explaining the dividend policy of Portuguese companies in the sample. The conclusion also states that differences exist in the importance of the explanatory factors to the amount of dividends distributed between the study samples, given the differentiation of dividend policies, followed by companies from each group analyzed.

The short article attempts to make some very brief reflections on the effects a lack of public policies positively discriminatory in terms of public employment retirement. In particular, the observation of the absurd contradiction between the average age of retirement at the time of death (for men and women) and the average pension time for men and women in public employment in Portugal.

O presente artigo analisa o sentido e alcance da nomenclatura desorçamentação. Trata-se de um neologismo recentemente usado na literatura das ciências económicas, e em especial nas finanças públicas, que tem gerado alguma controvérsia, resultando dali interpretações e visões muitas vezes dissemelhantes para o mesmo fenómeno. Embora o conceito não tenha tradução para outras línguas procurou-se fazer uma aproximação à sua semelhança terminológica em termos do seu significado. O contexto é, em especial, o Orçamento de Estado.

O presente artigo analisa os efeitos do custo, da grandeza e da complexidade que o sector público alcançou com o desenvolvimento do Estado de bem-estar Social.

Women are increasingly active in the participation and consumption of tourism, representing a strong and unique market segment. Knowledge of the needs and preferences of female tourists represents a key success factor in the tourism industry. This preliminary study seeks to capture the underlying reasons for the travel decisions of the residents of the Urban Quadrilátero of Minho, investigating their tourist motivations from a gendered perspective. Insight on tourism motivation may be an important policy tool for tourism planners and managers in the development of products and marketing strategies. The empirical analysis is undertaken based on questionnaires administered in 2012 to residents of the Urban Quadrilátero of Minho. Preliminary results do not reveal significant gender differences in the importance that the local residents place on various tourism motivation factors.

In cameras with radial distortion, straight lines in space are in general mapped to curves in the image. Although epipolar geometry also gets distorted, there is a set of special epipolar lines that remain straight, namely those that go through the distortion center. By finding these straight epipolar lines in camera pairs we can obtain constraints on the distortion center(s) without any calibration object or plumbline assumptions in the scene. Although this holds for all radial distortion models we conceptually prove this idea using the division distortion model and the radial fundamental matrix which allow for a very simple closed form solution of the distortion center from two views (same distortion) or three views (different distortions). The non-iterative nature of our approach makes it immune to local minima and allows finding the distortion center also for cropped images or those where no good prior exists. Besides this, we give comprehensive relations between different undistortion models and discuss advantages and drawbacks.

The radial undistortion model proposed by Fitzgibbon and the radial fundamental matrix were early steps to extend classical epipolar geometry to distorted cameras. Later minimal solvers have been proposed to find relative pose and radial distortion, given point correspondences between images. However, a big drawback of all these approaches is that they require the distortion center to be exactly known. In this paper we show how the distortion center can be absorbed into a new radial fundamental matrix. This new formulation is much more practical in reality as it allows also digital zoom, cropped images and camera-lens systems where the distortion center does not exactly coincide with the image center. In particular we start from the setting where only one of the two images contains radial distortion, analyze the structure of the particular radial fundamental matrix and show that the technique also generalizes to other linear multi-view relationships like trifocal tensor and homography. For the new radial fundamental matrix we propose different estimation algorithms from 9,10 and 11 points. We show how to extract the epipoles and prove the practical applicability on several epipolar geometry image pairs with strong distortion that - to the best of our knowledge - no other existing algorithm can handle properly.

Tourism represents a major economic activity in Portugal, with an enormous wealth and employment growth potential. A significant proportion of jobs in the industry tourism are occupied by women, given that this industry is characterized by a relatively higher percentage of female employees. Despite the evidence of female progress with regard to their role in the Portuguese labor market, women continue to earn less than their male counterparts. This is clearly the case of the tourism industry, where statistics reveal a persistent gender wage gap. The objective of this paper is to provide empirical evidence on the determinants of gender wage inequality in the tourism industry in northern Portugal. Relying on firm-level wage equations and production functions, gender wage and productivity differentials are estimated and then compared. The comparison of these differentials allows inferring whether observed wage disparities are attributable to relatively lower female productivity, or instead disparities are due to gender wage discrimination. This approach is applied to tourism industry data gathered in the matched employer-employee data set Quadros de Pessoal (Employee Records). The main findings indicate that female employees in the tourism industry in northern Portugal are less productive than their male colleagues and that gender differences in wages are fully explained by gender differences in productivity.

For modern consumer cameras often approximate calibration data is available, making applications such as 3D reconstruction or photo registration easier as compared to the pure uncalibrated setting. In this paper we address the setting with calibrateduncalibrated image pairs: for one image intrinsic parameters are assumed to be known, whereas the second view has unknown distortion and calibration parameters. This situation arises e.g. when one would like to register archive imagery to recently taken photos. A commonly adopted strategy for determining epipolar geometry is based on feature matching and minimal solvers inside a RANSAC framework. However, only very few existing solutions apply to the calibrated-uncalibrated setting. We propose a simple and numerically stable two-step scheme to first estimate radial distortion parameters and subsequently the focal length using novel solvers. We demonstrate the performance on synthetic and real datasets.

Consideramos de interés realizar un análisis financiero de la banca virtual en España para ser capaces de posicionar aquellas entidades bancarias que vieron en el canal de Internet una vía de expansión hacia nuevos clientes o como consolidación de los existentes, ya que todos los bancos creados en España de carácter virtual son filiales de grandes grupos bancarios. Utilizamos como modelos de análisis la aplicación de los métodos multicriterio CAMEL y Promethee. Como conclusiones del trabajo se observa que, independientemente del método utilizado, la entidad que mejor se posiciona para el periodo de análisis estudiado (2004-2010) es Bancopopular-e. No obstante, son entidades que todavía alcanzan valores muy bajas de rentabilidad y liquidez y donde datos como la eficiencia o la calidad de activos son muy mejorables.

The problematic of dividends paid out by firms has deserved the attention of several studies, theoretical and empirical, on corporate finance. This article intends to contribute to the theme by determining the factors that influence a firm’s dividends` policy. In this sense, it investigates the effect of a set of factors on the dividends paid out by issuing non financial firms belonging to Euronext Lisbon. Results suggest the existence of firm specific characteristics influencing its dividends policy. A firm’s Cash-flow and its stocks` market price seem to have a positive impact on the dividends paid out to stockholders. In issuing non financial firms that belong to the PSI 20 Index results additionally show the existence of a negative effect of net profits on dividend’s payment.

El principal finalidad de la presente comunicación se traduce en el análisis del efecto de los indicadores de desempeño empresarial en la explicación del precio de las acciones que integran el principal índice bursátil de la Euronext Lisboa, el PSI 20. Para tal, recurrimos a un análisis fundamental, habiendo dividido los indicadores de desempeño empresarial en dos grupos, un con un cariz económico-financiero otro con un cariz bursátil. Utilizando una muestra de 17 empresas, los resultados son obtenidos a través de la aplicación del método OLS y reportan a 31 de Diciembre de 2007. Los resultados obtenidos sugieren que los indicadores de desempeño empresarial se presentan susceptibles de explicar el precio de mercado de las acciones de las empresas que integran el PSI 20. Se destaca el efecto significativamente positivo del resultado líquido y del valor contable y el efecto significativamente negativo del cash-flow. Los resultados obtenidos sugieren la existencia de una expectativa positiva relativamente al desempeño futuro de las empresas que integran el PSI 20.

The main objective of this paper is to analyse the effect of firms’ performance indicators in explaining the price of stocks in the Portuguese capital market, using a fundamental analysis. In the empirical setting, firms’ performance indicators are gathered into two groups: (1) economic and financial indicators and (2) stock market indicators. Using a sample of 38 firms quoted at Euronext Lisbon, estimates are obtained trough an Ordinary Least Squares (OLS) model and report to December, 31 2007. Results suggest that performance indicators are able to explain the firms’ stock market price. There is a significant positive impact of sales growth and of payout ratio, while we find a statistically significant negative effect of the firm’s financial autonomy on the stock market price for the majority of firms quoted at Euronext Lisbon.

El objetivo de este trabajo es alcanzar conclusiones acerca de si existe relación entre los resultados empresariales, medidos a través de ratios tanto de tipo económicofinancieros como bursátiles, y el precio de mercado de las acciones de las empresas que conforman el Ibex 35, como índice que recoge la evolución diaria de los 35 valores más importantes del mercado español. La conclusión fundamental es que las variables rentabilidad económica, valor contable y ratio PER son consideradas estadísticamente significativas en la explicación del precio de mercado de las acciones del Ibex 35.

La presente comunicación tiene como objetivo central el análisis de los factores explicativos de la política de dividendos de las empresas que integran el principal índice bursátil del mercado de capitales portugués, el PSI 20. Con ese designio, utilizamos un conjunto de informaciones económicas y financieras de las empresas no financieras para explicar los dividendos por acción distribuidos en el período temporal comprendido por los años de 2005 a 2009. Los resultados logrados en el estudio empírico sugieren que el resultado líquido, los dividendos por acción distribuidos en el ejercicio económico anterior y el crecimiento de las ventas presentan un efecto positivo y estadísticamente significativo en la explicación de los dividendos por acción distribuidos en un determinado ejercicio económico. Sugieren todavía que el modelo desarrollado por Lintner (1956) se presenta válido para explicar la política de dividendos de las empresas de lo PSI 20.

In this investigation, a cluster analysis was used to separate Guimara˜es (Portugal) residents into clusters according to their perceptions of the impacts of tourism development. This approach is uncommonly applied to Portugal data and is even rarer for world heritage sites. The world heritage designation is believed to make an area more attractive to tourists. The clustering procedure analysed 400 data observations from a Guimara˜es resident survey and revealed the existence of three clusters: the Sceptics, the Moderately Optimistic and the Enthusiasts. The results were consistent with the empirical literature’s results, with the emergent nature of the destination found to be relevant. The fact that tourism is relatively recent in this destination has its major reflex in the devaluation by most of the residents of the negative impacts of tourism development.

Guimarães has hosted, during the year of 2012, one of the European Capital of Culture (ECOC). The evaluation of the event is needed as public, private and community funds are involved. The approach considers the tourists (domestic and international) as external and independent stakeholders who assessed the cultural activities developed during the event and the attributes of the city. The results of the survey show that hosting the 2012 ECOC was a major contribution for attracting new visitors to the city, although many of them just for a short period of time. The main source of general information collected by tourists was the Internet, and the traditional media. Only a small amount of respondents demonstrated a specialized knowledge of the cultural program. The most cited and appreciated performances came from the areas of music, exhibitions, and theatre. According to the perceptions of tourists, the tangible assets were clearly detached from the set of attributes of Guimarães, including buildings, churches and chapels, whereas intangible assets were less noted. Overall, Guimarães received a very positive evaluation related to city image and stay and is highly recommended by tourists to friends and relatives.

A nomeação de Guimarães como Capital Europeia da Cultura (CEC), em 2012, suscitou grandes expectativas na comunidade local, nos territórios limítrofes e, de um modo geral, na população portuguesa. No entanto, muitos dos potenciais impactos são ainda pouco perceptíveis pela maior parte das pessoas, se bem que muitas delas antecipem que os impactos sejam positivos. A presente comunicação pretende aferir, de forma prospectiva, os possíveis impactos do acolhimento por Guimarães da CEC, em 2012. Por referência a experiências anteriores de organização de outras CEC, procura-se identificar alguns dos efeitos, em termos de atracção de turistas (nacionais e internacionais), das actividades culturais programadas, disponibilidades orçamentais e audiências, bem como aferir do potencial impacto económico e do legado do evento para o futuro da cidade. Com base na análise efectuada, pode concluir-se que Guimarães CEC 2012 oferece um potencial de atracção para o Norte do país e região da Galiza, possui um orçamento, por habitante, comparável a outras CEC e beneficia do empenhamento dos agentes locais. Menos positiva é a distância da cidade a dois dos principais destinos turísticos nacionais (Lisboa e Algarve), a extensão da programação cultural do evento, o fraco envolvimento dos agentes culturais locais no programa de actividades do evento e a inexistência de espaços museológicos de referência internacional. Em contrapartida, destaca-se a existência de ligações aéreas de baixo custo a várias cidades Europeias através do aeroporto do Porto, a possibilidade de reposicionar a imagem da cidade ao nível nacional e internacional, a disponibilização de fundos para a revitalização urbana do centro histórico e o aumento esperado do número de turistas (nacionais e estrangeiros). A recessão económica (nacional e Europeia), as dificuldades orçamentais, a pouca ambição da política de angariação de patrocínios e de recursos financeiros privados e a sustentabilidade do evento no futuro são algumas ameaças que poderão comprometer o sucesso de Guimarães CEC 2012.

Guimarães hosted the European Capital of Culture (ECOC) during the year of 2012. This study investigates the differences between Portuguese and foreign tourists regarding the main motivations to visit Guimarães and the retained perceived image of the destination. To achieve that purpose a survey was administered to 390 tourists that visited the city during the cultural event. The results show that tourists who visited Guimarães are relatively young, wealthy, employed and well educated. They are touring around the northern part of the country which includes an itinerary beginning in Porto, and extended to other important neighboring cities such as Braga or Viana do Castelo. The main motivations to visit the city, for both Portuguese and foreign tourists, are its historical heritage and the title of ECOC, the associated cultural events and celebrations that take place during 2012. However, these items were more valued by foreigners than Portuguese tourists. Using a factor analysis the tourists’ perceived attributes of Guimarães were described in four dimensions: “material heritage”, “intangible heritage”, “cultural performance”, and “sport and education”. Although foreigners and nationals perceived the tourism attributes of the city differently, the comparison of the mean scores of the four factors across Portuguese and foreigner tourists reveals that the most valued and least valued factors are common to both groups.

This paper aims to describe the processes of teaching illustration and animation, together, in the context of a masters degree program. In Portugal, until very recently, illustration and animation higher education courses, were very scarce and only provided by a few private universities, which offered separated programs - either illustration or animation. The MA in Illustration and Animation (MIA) based in the Instituto Politécnico do Cávado e Ave in Portugal, dared to join these two creative areas in a common learning model and is already starting it’s third edition with encouraging results and will be supported by the first international conference on illustration and animation (CONFIA). This masters program integrates several approaches and techniques (in illustration and animation) and integrates and encourages creative writing and critique writing. This paper describes the iterative process of construction, and implementation of the program as well as the results obtained on the initial years of existence in terms of pedagogic and learning conclusions. In summary, we aim to compare pedagogic models of animation or illustration teaching in higher education opposed to a more contemporary and multidisciplinary model approach that integrates the two - on an earlier stage - and allows them to be developed separately – on the second part of the program. This is based on the differences and specificities of animation (from classic techniques to 3D) and illustration (drawing the illustration) and the intersection area of these two subjects within the program structure focused on the students learning and competencies acquired to use in professional or authorial projects.
