Spatial joins

2019

The spatial join is a popular operation in spatial database systems and its evaluation is a well-studied problem. This paper reviews research and recent trends on spatial join evaluation. The complexity of different data types, the consideration of different join predicates, the use of modern commodity hardware, and support for parallel processing open the road to a number of interesting directions for future research, some of which we outline in the paper.

Transnational Social Network Analysis

2012

AbstractThe following article discusses methods of social network analysis (SNA) as an approach in researching transnational social formations. SNA allows transnationality to be studied through relationships between actors, enabling the investigation of social structures which expand nation-state frameworks. Two empirical examples are used to address the central characteristics of the network analysis approach (focus on relations, systematic collection of data, means of visualising network data) and their relevance for research on cross-border social phenomena. The article also investigates the significance of geographical mobility in the research process, culminating in reflection on how “…

Strategies for Making Life

2014

Synthetic biology is a multifaceted discipline and the pathways towards an artificial cell are diverse. Top-down strategies seek simplification of genomes, their chemical synthesis and transplantation into a cell chassis. In the long term, scientists hope to have genomic platforms to reinvent metabolic networks capable of producing molecules of biotechnological interest. On the other hand, a bottom-up strategy relies on the chemical implementation of fundamental concepts such as self-reproduction, self-replication and self-maintaining systems. In addition to the artificial synthesis of simplified genomes and protocells, some scientists explore xenobiology, or making life as we do not know i…

Crowdsourcing Fundamentals: Definition and Typology

2015

Crowdsourcing is a problem-solving and task realization model that is being increasingly used. Thanks to the possibility of harnessing the collective intelligence from the Internet; thanks to the crowdsourcing initiatives people can, for example, find a solution to a complex chemical problem, get images tagged, or get a logo designed. Due to its success and usefulness, more and more researchers have focused their interest on this concept. This fact has shown that the concept of crowdsourcing has no clear boundaries, and although over time the concept has been better explained, some authors describe it differently, propose different types of crowdsourcing initiatives, or even use contradicto…

Identifying the Optimum Social Site that Could Serve eLearning Purposes: A Preliminary Analysis

2020

Nowadays, an increasingly attractive research domain is represented by the integration of eLearning systems with the Social Media tools. However, identifying the proper Social Media platform to serve educational purposes could be an extremely hard task, mainly due to the variations from platform to platform. Thus, the first aim of this article is to identify the optimum typology that could be successfully integrated with eLearning systems. Moving forward, a classification of the top 20 most popular Social Media sites at global level in terms of their main objectives will be required in order to asses a specific typology of each of this. Thereafter, we propose a preliminary model of comparis…

Information assets: A typology of disclosed and non-disclosed information

2020

Abstract The debate surrounding the value of disclosed and non-disclosed information as a competitive element has stalled; it has not been possible to make a universal, precise claim as to their potential to generate competitive advantages. This empirical inconsistency can be explained in part by the heterogeneity of information assets, which can give rise to different information dimensions, each offering different potential for generating results depending on the degree to which they meet the conditions of complementarity and co-specialization with other resources. This article helps to move forward on this issue by presenting a theoretical construct of the concept “information assets" an…

Using OLAP Data Cubes in Business Intelligence

2016

Abstract The purpose of this paper is to demonstrate that it is possible to develop business intelligence projects in big and medium-size organizations, only with Microsoft products, used in accordance with standard OLAP cube technology, and presented possible alternatives, in relation with the requested functions.

Construct validity of the Moral Development Scale for Professionals (MDSP)

2011

Olle Söderhamn1,2, John Olav Bjørnestad1, Anne Skisland1, Christina Cliffordson21Faculty of Health and Sport Sciences, University of Agder, Grimstad and Kristiansand, Norway; 2Department of Nursing, Health and Culture, University West, Trollhättan, SwedenAbstract: The aim of this study was to investigate the construct validity of the Moral Development Scale for Professionals (MDSP) using structural equation modeling. The instrument is a 12-item self-report instrument, developed in the Scandinavian cultural context and based on Kohlberg’s theory. A hypothesized simplex structure model underlying the MDSP was tested through structural equation modeling. …
