Reusability in software engineering

This paper surveys recent work concerning reusability in software engineering. The current directions in software reusability are discussed, and the two major approaches of reusable building blocks and reusable patterns studied. An extensive bibliography, parts of which are annotated, is included

Mapping Big Data into Knowledge Space with Cognitive Cyber-Infrastructure

Big data research has attracted great attention in science, technology, industry and society. It is developing with the evolving scientific paradigm, the fourth industrial revolution, and the transformational innovation of technologies. However, its nature and fundamental challenge have not been recognized, and its own methodology has not been formed. This paper explores and answers the following questions: What is big data? What are the basic methods for representing, managing and analyzing big data? What is the relationship between big data and knowledge? Can we find a mapping from big data into knowledge space? What kind of infrastructure is required to support not only big data management and analysis but also knowledge discovery, sharing and management? What is the relationship between big data and science paradigm? What is the nature and fundamental challenge of big data computing? A multi-dimensional perspective is presented toward a methodology of big data computing.Comment: 59 page

The Global Organic Food Market and Transformation Deductive Definition of Empiric Indicators The Demand Explanation The Institutional Explanation & Comparative Country Report: Denmark versus Sweden

The present study is part of the project “Public Policies and Demand for Organic Food: An International Comparison of Policy Effects and Policy Determinants” (COP). It is carried out in WP II that concerns the supply-side policies and demand. In the WP it has been an initial task to formulate a theoretical approach as the conceptual framework to be used in comparative studies. The present study represents the first contribution to apply the conceptual framework in an empirical context and here it is the evolution of the organic sectors in Denmark and Sweden that are compared. The study is searching for indicators to explain which factors can explain increase in organic foods production and consumption. It reaches the conclusion that the picture concerning the demand side is very blurred and that it is impossible to reveal which elements are crucial. However, the study also concludes that institutional design and set up seem to be rather crucial for the evolution of the organic sector
