Why braille reading is important and how to study it /Por qué es importante la lectura en braille y cómo estudiarla
2016
AbstractDespite its relevance in theoretical and practical terms, braille reading has received little attention from researchers. Awareness of the pros and cons of the different procedures used to examine braille reading is needed to facilitate the realization of systematic studies and to improve teaching methods in braille reading. This study provides a critical examination of braille reading methods and highlights key points for future studies on tactile reading.
Studying social media as semiotic technology: a social semiotic multimodal framework
2018
How do we study social media technology? While social semiotics provides an extensive toolkit for analysing multimodal texts and semiotic practices, the study of social media as semiotic technology poses a significant challenge to existing research methodologies. In this article, we present a social semiotic framework that allows us to describe in analytical details the multimodal meaning potentials offered by digital social media technology and connect these to multimodal text-making and semiotic practices while underscoring the role of technology. Our framework is organized around seven interrelated and inherently informed dimensions: (1) multimodality, (2) practice, (3) the social, (4) m…
Biotechnology and Cultural Heritage Conservation
2020
The deterioration of cultural asset is induced by biological, chemical, and physical factors, influenced by anthropogenic activity and environmental conditions. In this study, the contribution of biotechnology is emphasized to define the conservation strategy, for a marble Fountain (Two Dragons, XV century) located in Palermo city center, based on an integrated approach and eco-friendly procedures. Biotechnological protocols are preliminarily applied as an integrated approach, based on microscopy observation, in vitro culture and genomic DNA analysis to recognize and characterize microbial communities. Several biological systems have been identified: green algae (Chlorella) and cyanobacteri…
Extending customer relationship management. From empowering firms to empowering customers
2013
Purpose – The focus of customer relationship management (CRM) literature has been predominantly on the firm perspective and on IT, not on customer or service orientation and value co-creation. This paper seeks to explore and analyse contemporary CRM frameworks and suggests future research directions. To achieve this, a thorough literature review on CRM is conducted focusing on recent advances within CRM. This provides a good basis for critically analysing the current status of both CRM theory and practice. Design/methodology/approach – The paper reviews CRM literature published 2003-2011. Based on the literature review, it introduces a conceptual framework of the changing role of customer d…
Computational Models That Matter During a Global Pandemic Outbreak
2020
The COVID-19 pandemic is causing a dramatic loss of lives worldwide, challenging the sustainability of our health care systems, threatening economic meltdown, and putting pressure on the mental health of individuals (due to social distancing and lock-down measures). The pandemic is also posing severe challenges to the scientific community, with scholars under pressure to respond to policymakers’ demands for advice despite the absence of adequate, trusted data. Understanding the pandemic requires fine-grained data representing specific local conditions and the social reactions of individuals. While experts have built simulation models to estimate disease trajectories that may be enough to gu…
Capturing daily family dynamics via text messages: development of the mobile diary
2010
In this paper we introduce a new tool, the mobile phone, for use in diary research. We demonstrate, with reference to two family studies conducted in Finland, how daily family dynamics can be captured by using the mobile diary. In both studies family members sent text messages (SMSs) in answer to structured diary questions three times a day over a one-week period. The participants kept also paper-and-pencil diaries. Two mobile diary items measuring mood (stressfulness and feelings of competence) both at home and at work are reported here as examples. For both items we found statistically significant daily and weekly variation as well as individual fluctuation. The data gathered by the mobil…
Metadata to Support Data Warehouse Evolution
2009
The focus of this chapter is metadata necessary to support data warehouse evolution. We present the data warehouse framework that is able to track evolution process and adapt data warehouse schemata and data extraction, transformation, and loading (ETL) processes. We discuss the significant part of the framework, the metadata repository that stores information about the data warehouse, logical and physical schemata and their versions. We propose the physical implementation of multiversion data warehouse in a relational DBMS. For each modification of a data warehouse schema, we outline the changes that need to be made to the repository metadata and in the database.
Spatio-temporal Schema Integration with Validation: A Practical Approach
2005
We propose to enhance a schema integration process with a validation phase employing logic-based data models. In our methodology, we validate the source schemas against the data model; the inter-schema mappings are validated against the semantics of the data model and the syntax of the correspondence language. In this paper, we focus on how to employ a reasoning engine to validate spatio-temporal schemas and describe where the reasoning engine is plugged into our integration methodology. The validation phase distinguishes our integration methodology from other approaches. We shift the emphasis on automation from the a priori discovery to the a posteriori checking of the inter-schema mapping…

PDB: A pictorial database oriented to data analysis
1993
The paper describes a new pictorial database oriented to image analysis, implemented inside the MIDAS data analysis system. Pictorial databases need expressive data structures in order to represent a wide class of information from the numerical to the visual. The model of the database is relational; however, a full normalization is not achievable, owing to the complexity of the visual information. The paper reports the general design and notes on the software implementation. Preliminary experiments show the performance of the pictorial database. Copyright © 1993 John Wiley & Sons, Ltd
