Enterprise architecture (EA) implementation refers to a set of activities ultimately aiming to align business objectives with information technology infrastructure in an organization. EA implementation is a multidisciplinary, complicated and endless process, hence, calls for adequate education and training programs that will build highly skilled personnel (called enterprise architects) with diverse competencies. This development of domain‐specific competencies is also supported by European policies on education and vocational training. To this end, the authors present training uses of the Enterprise Architecture Competence Framework (EA‐CF). EA‐CF is a proposed conceptual model that describes EA competencies in compliance to the European e‐Competence Framework (e‐CF). The authors argue that EA stakeholders can consult the framework regarding competencies they want to underpin and thus identify the corresponding skills, knowledge and attitudes that result as learning outcomes in EA courses and training programs. 相似文献

In this paper, I develop an overlapping generations endogenous growth model in which both public education and health are sources of growth by affecting the accumulation rate of the human capital stock and the savings rate over life expectancy. I first find that dynamic complementarities of public expenditures lead to minimum threshold levels of public education and health expenditures that ensure sustainable growth. I then show how governments can use the allocation of public expenditures as an alternative policy instrument to maximize growth without increasing the tax rate or the retirement age, as usually happens in aging economies. 相似文献

The main purpose of this paper is the identification of the characteristics of takeover targets in a small open economy like Greece, using the market for corporate control (MCC) hypothesis as theoretical background. Contrary to this hypothesis, the results indicate that the motives for merging or acquisition activities are basically of strategic character. Using a sample of 35 acquired and 105 non‐acquired firms, the sampling process was initially performed by a modified methodology of state‐based sampling, even if its nature cannot be recognized by the classical maximum likelihood estimator (MLE) of logit model. Subsequently, taking into account the small size of the sample, we develop and use, in the logit context, the bootstrap MLE as an advanced alternative method for reducing inherit bias and inefficiency. The findings remain uniform supporting the strategic motives explanation in actual takeover activities, a fact that clearly illustrates the framework of merger policies followed by the Greek Competition Committee during the period under study. 相似文献

Technology education is a well-established field of knowledge whose applications have many ramifications. For example, technology
education may be used as a tool in meeting the challenges of sustainable development. However, the usefulness of technology
education to the sustainability debate as a whole and to education for sustainable development in particular, has largely
been overlooked in the past. Indeed, there is a paucity of academic studies which examine the contribution technology education
may provide to education for sustainable development. On the basis of the need to address this knowledge gap, this paper reviews
the state of affairs in relation to education for sustainable development and considers its links and appropriateness to technology
education. A further objective of this paper is to present examples of initiatives and existing practices around the world,
drawing partly from the results of the 1st European Conference on Education for Sustainable Development held in Greece in
October 2007, as well as from other initiatives undertaken in Europe and North America. Finally, some measures that may be
adopted in order to enhance the contribution of technology education to education for sustainable development are outlined. 相似文献

This article examines the evolution of social security research from a theoretical and empirical perspective. This is done through an extensive review and analysis of publications from the Journal of International Social Security Review published by Wiley within a 50-year period (1967–2017). It was observed that at a different period in time, the social security research focused on different national and international issues that invoked different social welfare programs and pension systems approach (public or private) to facilitate the explanation of its final socio-economic impact into different social groups in the same country or region respectively. 相似文献

Human society is on a collision course with nature, thus its sustainability is seriously questioned nowadays. To understand this problem better it is essential to define and measure sustainability. In this paper a model that uses fuzzy logic, called SAFE, is used to measure sustainability. The sustainability of a country is based on a multitude of basic indicators. In all 75 indicators for 128 countries are used. This work extends SAFE as follows: (a) The model is amended by an imputation procedure to fill in missing data, (b) the rule bases of SAFE are compiled algebraically, and (c) sustainability thresholds are defined so as to reflect expert opinion and international agreements and norms. Countries are ranked according to their sustainability index. Switzerland and Sweden take the first two places and Mauritania and Sudan the two last ones. A sensitivity analysis pinpoints those basic indicators that affect sustainability the most. Decision makers may focus on these indicators to improve sustainability. 相似文献

Abstract: This paper suggests a recursive application of Fama and MacBeth's (1973) testing procedure to assess the significance of macroeconomic factors and firm-specific effects priced in explaining the cross-sectional variation of expected stock returns over time. The paper applies the suggested testing procedure to investigate the source of risks of the Athens Stock Exchange (ASE). Among the variables examined, it finds out that the changes in the short term interest rates and firm size can explain a significant proportion of the variation of the ASE individual returns. The paper argues that the significance of interest rate changes can be associated with monetary policy changes introduced by the Greek authorities after the mid-nineties. These changes were focused on targeting interest rates, instead of monetary aggregates. 相似文献

We examine the role of financial development in economic growth in the former Communist countries of Central and Eastern Europe and the Commonwealth of Independent States during the first two decades since the beginning of transition. These countries, which had undeveloped financial systems under Communism, provide an interesting test of the relationship between financial development and growth. Our study is the broadest in terms of coverage and time period. We find that measures of financial market efficiency and competitiveness are more important than the size of the market in terms of promoting economic growth. 相似文献
