Sustainable development is a concern and a challenge of modern societies, either in developing and developed countries. Good governance is crucial to managing efficiently all kind of resources, including natural resources, for the well-being of current and future generations. Digital transformation can be a key driver of changes in governments if they want to enhance transparency, accountability and efficiency. E-government facilitates integrated policies and public services to promote sustainable and inclusive economic growth, social development and environmental protection. E-government contributes to efficient resource management, and so can help to improve namely natural resource usage in the present to avoid damage to their usage in the future. The aim of this study is to analyse the impact of e-government on sustainable development. Using a logit model, for a sample of 103 countries in the period 2003–2018, the results suggest that e-government development is a positive determinant for a country to attain sustainable development, proxied by adjusted net savings, that embraces a country’s economic, social and environmental development. This study provides evidence that e-government increases the probability to attain sustainable development mostly in developing and transition economies. The results also suggest that economic growth and gross national income per capita are significant positive influences in sustainable development in the whole sample and that countries with lower age dependency and natural resource rents are more likely to have sustainable development. Developing e-government allows promoting sustainable development, particularly in developing and in transition economies.

ABSTRACT. The Minimization of Open Stacks Problem (MOSP) is a Pattern Sequencing Problem that often arises in industry. Besides the MOSP, there are also other related Pattern Sequencing Problems of similar relevance. In this paper, we show that each feasible solution to the MOSP results from an ordering of the vertices of a graph that defines the instance to solve, and that the MOSP can be seen as an edge completion problem that renders that graph an interval graph. We review concepts from graph theory, in particular related to interval graphs, comparability graphs and chordal graphs, to provide insight to the structural properties of the admissible solutions of Pattern Sequencing Problems. Then, using Olariu's characterization and other structural properties of interval graphs, we derive an integer programming model for the MOSP. Some computational results for the model are presented.

The main objective of this study is to empirically test capital structure decisions in Portuguese family-owned businesses under trade-off theory (TOT) and pecking order theory (POT) and attend to the relationships between family/business interaction and agency conflicts. Family-owned businesses are essential for the development of economies, but the financing logic they adopt is not yet adequately clarified by scientific research, especially as they are more exposed to the constraints of markets imperfections. The specific pattern of business ownership may affect the financing decision and the ability to obtain funds externally. This issue is more relevant in economies where family business initiatives and less sophisticated management strategies are expressive. The greater convergence of interests in family businesses and the consequent decrease in agency costs may lead to higher levels of recognized reputation and thus easier access to indebtedness. The empirical study uses static models and dynamic panel models in order to analyze data from 4,952 Portuguese family-owned firms over the period from 2009 to 2016: the TOT following the partial debt adjustment model, and the POT following the model of the impact of the deficit of funds on debt and the model of the relationship between debt and the determinants of financing. The results of the individual tests suggest that Portuguese family-owned businesses adjust debt at the target ratio, albeit influenced by adjustment costs that keep them distant from the optimal, as well as use sources other than debt when a financial deficit occurs. Although the impact of the financial deficit is greater in total debt ratio, the velocity of adjustment to the optimal level is higher in short-term debt. Evidence from a joint test confirms that both theories explain part of the capital structure of Portuguese family-owned businesses.

Abstract. Global Entrepreneurship Monitor is a large scale database for internationally comparative entrepreneurship that includes information about many aspects of entrepreneurship activities, perceptions, conditions, national and regional policy, among others, of a large number of countries. This project has two main sources of primary data: the Adult Population Survey and the National Expert Survey. In this work the 2011 and 2012 National Expert Survey datasets are studied. Our goal is to analyze the effects of the different type of entrepreneurship expert specialization on the perceptions about the Entrepreneurial Framework Conditions. For this purpose the multivariate analysis of variance is used. Some similarities between the results obtained for the 2011 and 2012 datasets were found, however the differences between experts still exist.
