Model independent assertions for integration of heterogeneous schemas
1992
Due to the proliferation of database applications, the integration of existing databases into a distributed or federated system is one of the major challenges in responding to enterprises' information requirements. Some proposed integration techniques aim at providing database administrators (DBAs) with a view definition language they can use to build the desired integrated schema. These techniques leave to the DBA the responsibility of appropriately restructuring schema elements from existing local schemas and of solving inter-schema conflicts. This paper investigates the assertion-based approach, in which the DBA's action is limited to pointing out corresponding elements in the schemas an…
A Framework to Explain the Relation Between ICT and Development: Combining Affordances and the Capability Approach
2019
Part 1: Pushing the Boundaries - New Research Methods, Theory and Philosophy in ICT4D; International audience; In this paper, we suggest a framework to better explain the relation between ICT and development. The framework combines two theories: The Capability Approach and Affordances. The capability approach defines development as freedom of choice; and the affordances explains the relational aspects of people and technology. These two theories complement each other by connecting the means (technology) to the ends (development). A case study of ICT and study-circle education in rural areas of Kenya is used to illustrate the framework. Using the framework, the study revealed how actualizati…
A triplet under focus:Innovation, design and the city
2018
Three key concept domains are considered and explored in a unitary framework. They are: innovation, the only possible response to global crises, aiming at transforming behaviours and practices towards systemic changes and transition; design, a way of creatively conceiving, developing and driving forward new practices for undertaking large scale transitions; and cities, seen as the environments where problems present themselves in the most socially relevant way and at the same time as key opportunities for testing and adopting forms of innovation which target global challenges. The chapter positions the three key concepts in relation to the most relevant academic references and to the curren…
Big Data Analytics Affordances for Social Innovation: A Theoretical Framework
2021
This paper proposes a theoretical framework to identify the mechanisms by which actors perceive the affordances of big data analytics (BDA) and how institutional voids and supports enable or hinder the actualisation of those perceived affordances. In doing so, we contribute to identifying the missing link needed to understand the social innovation process in relation to BDA. The framework paves the ground towards understanding the institutionalization process of social innovation and its implications for research and practice.
Managing Knowledge in Academic Libraries Are we? Should we?
2016
This article gives an overview of the field of knowledge management and suggests how this can be applied to academic libraries. A literature review has been conducted and has been subject to a critical analysis of comparison to IFLAs standard for “Continuing Professional Development: Principles and Best Practices” (IFLA, 2015). Here IFLA has identified 10 points of best practice. These 10 points will be measured against the literature in the field of knowledge management to ascertain if academic libraries would benefit from a stronger relation to knowledge management.
Business competencies and innovation capability in cross-border small regional enterprises
2017
This paper explores the socio-economic aspects of human capital, especially the IT users' innovation capability in regional cross-border small and medium-sized enterprises in Poland and in Germany. Socio-economic aspects of human capital are crucial for the socioeconomic development that may be achieved through virtual access to online learning tools and by diagnosing IT users' innovation capability and their business competencies, in relation to information and communication technologies. This paper presents an initial report on experimental research that was conducted online using the author's diagnostic tools. Conclusions and findings of this work contribute to socioeconomic development …
EXPLORING THE INPUT OF COMPETENCE ASSESSMENT TO GOAL-SETTING IN VARIOUS TYPES OF ORGANIZATIONS
2018
The aim of the present research is to investigate the existing practices of linking competence assessment to organizational goal-setting in various organisations in Latvia. The importance of linking employee competences to goal-setting within organizations has been established in scientific literature. Nevertheless, there is evidence gathered in this interdisciplinary research that existing methods of competence assessment used by various organizations in Latvia do not translate well into organizational goal-setting. The research is based on information gathered from semi-structured interviews with representatives of managerial positions in private and public, including educational service …
Early and midterm outcomes of bioresorbable vascular scaffolds for ostial coronary lesions: insights from the GHOST-EU registry.
2016
Aims: We aimed to investigate the outcomes of bioresorbable vascular scaffolds (BVS) in coronary ostial lesions. Ostial lesions represent a challenging angiographic subset, with higher event rates compared with non-ostial lesions. BVS might be associated with advantages over the long term, but their safety in this setting remains to be explored. Methods and results: Procedural and 12-month follow-up data from consecutive patients treated with BVS for lesions located at the ostium of the right (RCA), left anterior (LAD) or circumflex (LCX) coronary in 11 European centres were collected. The primary device-oriented endpoint was defined as a combination of cardiovascular death, target vessel m…
Writing as a Learning Tool
2001
How learning is understood in everyday schooling and conceptualized in research varies a great deal, as does the way in which writing is used for enhancing learning. This paper reviews recent research conducted mainly in Europe, North Arrierica, and Australia to outline what kind of challenges research is facing at the moment. The paper begins with examining how the concept of learning is defined in everyday use and in research. It considers the analysis of learning conceptions important because the way that learning is understood greatly determines how writing is used as a tool for learning. Second, it analyzes the theoretical basis for using writing as a learning tool--theories are divide…
Laparoscopic distal pancreatectomy: what factors are related to the learning curve?
2014
none 7 no PURPOSE: The factors related to the learning curve for laparoscopic distal pancreatectomy have rarely been evaluated. METHODS: A retrospective study of 32 patients who underwent a laparoscopic distal pancreatectomy performed at a high-volume center by a single pancreatic surgeon experienced with laparoscopic surgery was conducted. Pre-, intra- and postoperative data were collected. The primary endpoint was the length of the operation. The secondary endpoints were the conversion and reoperation rates, overall postoperative morbidity and mortality rates, the length of hospital stay and rate of unplanned splenectomy. RESULTS: The length of the operation and the cumulative sum of the …
