Development of a conceptual model of sustainable building from a university
2021
Introduction: In this paper, the authors aim is to develop a conceptual model that aims to facilitate the processes of implementing sustainability and / or assessment of sustainable performance in a Higher Education Building (HEB). The conceptual model could also be used to compare two or more buildings of higher education in terms of sustainability. Methodology: The authors started the scientific research with the literature review in order to identify and analyze the most relevant aspects that are frequently assess and could influencing the components of sustainability in higher education institutions. These aspects were clustered into categories and for each of them were established obje…
Methodological approach for evaluating the geo-exchange potential: VIGOR Project
2012
In the framework of VIGOR Project, a national project coordinated by the Institute of Geosciences and Earth Resources (CNR-IGG) and sponsored by the Ministry of Economic Development (MiSE), dedicated to the evaluation of geothermal potential in the regions of the Convergence Objective in Italy (Puglia, Calabria, Campania and Sicily), is expected to evaluate the ability of the territory to heat exchange with the ground for air conditioning of buildings. To identify the conditions for the development of low enthalpy geothermal systems collected and organized on a regional scale geological and stratigraphic data useful for the preparation of a specific thematic mapping, able to represent in a …
An urban drainage stormwater quality model: model development and uncertainty quantification
2010
Summary The evaluation of urban stormwater quality is of relevant importance for urban drainage, and mathematical models may be of great interest in this respect. To date, several detailed mathematical models are available to predict stormwater quantity–quality characteristics in urban drainage systems. However, only a few models take sewer sediments into account, considering their cohesive-like properties that influence the build-up process of the pollutant load. Furthermore, the model data requirements, especially for the quality aspects, are extensive, which limit their applicability and affect model results with large uncertainty. Uncertainty analysis provides a measure or index regardi…
On Using Conceptual Modeling for Ontologies
2004
Are database concepts and techniques suitable for ontology design and management? The question has been on the floor for some time already. It gets a new emphasis today, thanks to the focus on ontologies and ontology services due to the spread of web services as a new paradigm for information management. This paper analyzes some of the arguments that are relevant to the debate, in particular the question whether conceptual data models would adequately support the design and use of ontologies. It concludes suggesting a hybrid approach, combining databases and logic-based services.
To Share or Not to Share: Supporting the User Decision in Mobile Social Software Applications
2007
User's privacy concerns represent one of the most serious obstacles to the wide adoption of mobile social software applications. In this paper, we introduce a conceptual model which tackles the problem from the perspective of trade-off between privacy and trust, where the user takes the decision with minimal privacy loss. To support the user decision, we introduce the Mobile Access Control List (Macl), a privacy management mechanism which takes into account the user attitude towards mobile sharing, his communication history and social network relationships.
Including functional usability features in a Model-Driven Development Method
2013
The Software Engineering (SE) community has historically focused on working with models to represent functionality and persistence, pushing interaction modelling into the background, which has been covered by the Human Computer Interaction (HCI) community. Recently, adequately modelling interaction, and specifically usability, is being considered as a key factor for success in user acceptance, making the integration of the SE and HCI communities more necessary. If we focus on the Model-Driven Development (MDD) paradigm, we notice that there is a lack of proposals to deal with usability features from the very first steps of software development process. In general, usability features are man…
The Relationship Between the Comprehensiveness of Corporate Annual Reports and Firm Characteristics in Spain
1994
Abstract Not much information exists in the international accounting literature on Spanish accounting. Spain is selected as a subject of study because it is different from those countries that are subjects of the research concerned with investigating the multivariate impact of firm characteristics on disclosure in annual reports and accounts. The conceptual model underlying our empirical tests is based on economic and political incentives for providing greater detail in corporate annual reports and accounts. The paper provides evidence that the amount of detail in Spanish corporate annual reports and accounts is increasing in firm size and stock exchange listing, and decreasing in liquidity.
Life-Based Design
2016
Technical artefacts should exist to bring added value and quality to people’s lives. HTI design should, therefore, be considered in a much broader context than merely the usage of technology. It should be based on an understanding of people’s lives and well-grounded design methods and tools, which can investigate life and apply this knowledge to the design work. The conceptual model of life-based design (LBD) is based on segregating unified systems of actions called forms of life. Investigating the structure of actions and related facts relevant to particular forms of life, in addition to the values that people follow, is the core tool of LBD. The knowledge produced constitutes a template f…
The Co-creation Canvas
2021
Abstract Digital transformation has become an increasingly important topic among enterprises and in research. The adoption of enterprise systems is such an investment, and it usually requires significant change management activities to realize the potential benefits. One important issue is how firms should go about to make investments in appropriate digital technology – and the appropriate changes to organizational processes and business models. This is particularly challenging for small and medium-sized enterprises (SMEs). They generally have very limited resources, and they usually depend on external input and cooperation with other companies. Therefore, a successful strategy for many SME…
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…
